Risks and benefits of sharing patient information on social media: a digital dilemma. EUROPEAN HEART JOURNAL. DIGITAL HEALTH 2024; 5:199-207. [PMID: 38774369 PMCID: PMC11104475 DOI: 10.1093/ehjdh/ztae009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/09/2023] [Revised: 02/05/2024] [Accepted: 02/05/2024] [Indexed: 05/24/2024]
Abstract
Social media (SoMe) has witnessed remarkable growth and emerged as a dominant method of communication worldwide. Platforms such as Facebook, X (formerly Twitter), LinkedIn, Instagram, TikTok, and YouTube have become important tools of the digital native generation. In the field of medicine, particularly, cardiology, attitudes towards SoMe have shifted, and professionals increasingly utilize it to share scientific findings, network with experts, and enhance teaching and learning. Notably, SoMe is being leveraged for teaching purposes, including the sharing of challenging and intriguing cases. However, sharing patient data, including photos or images, online carries significant implications and risks, potentially compromising individual privacy both online and offline. Privacy and data protection are fundamental rights within European Union treaties, and the General Data Protection Regulation (GDPR) serves as the cornerstone of data protection legislation. The GDPR outlines crucial requirements, such as obtaining 'consent' and implementing 'anonymization', that must be met before sharing sensitive and patient-identifiable information. Additionally, it is vital to consider the patient's perspective and prioritize ethical and social considerations when addressing challenges associated with sharing patient information on SoMe platforms. Given the absence of a peer-review process and clear guidelines, we present an initial approach, a code of conduct, and recommendations for the ethical use of SoMe. In conclusion, this comprehensive review underscores the importance of a balanced approach that ensures patient privacy and upholds ethical standards while harnessing the immense potential of SoMe to advance cardiology practice and facilitate knowledge dissemination.

Electronic and structural properties of Möbius boron-nitride and carbon nanobelts. DISCOVER NANO 2024; 19:63. [PMID: 38589649 PMCID: PMC11001837 DOI: 10.1186/s11671-024-03967-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/03/2023] [Accepted: 01/24/2024] [Indexed: 04/10/2024]
Abstract
For the development of nanofilters and nanosensors, we wish to know the impact of size on their geometric, electronic, and thermal stabilities. Using the semiempirical tight binding method as implemented in the xTB program, we characterized Möbius boron-nitride and carbon-based nanobelts with different sizes and compared them to each other and to normal nanobelts. The calculated properties include the infrared spectra, the highest occupied molecular orbital (HOMO), the lowest unoccupied molecular orbital (LUMO), the energy gap, the chemical potential, and the molecular hardness. The agreement between the peak positions from theoretical infrared spectra compared with experimental ones for all systems validates the methodology that we used. Our findings show that for the boron-nitride-based nanobelts, the calculated properties have an opposite monotonic relationship with the size of the systems, whereas for the carbon-based nanobelts, the properties show the same monotonic relationship for both types of nanobelts. Also, the torsion presented on the Möbius nanobelts, in the case of boron-nitride, induced an inhomogeneous surface distribution for the HOMO orbitals. High-temperature molecular dynamics also allowed us to contrast carbon-based systems with boron-nitride systems at various temperatures. In all cases, the properties vary with the increase in size of the nanobelts, indicating that it is possible to choose the desired values by changing the size and type of the systems. This work has many implications for future studies, for example our results show that carbon-based nanobelts did not break as we increased the temperature, whereas boron-nitride nanobelts had a rupture temperature that varied with their size; this is a meaningful result that can be tested when the use of more accurate simulation methods become practical for such systems in the future.

Attainment of LDL-Cholesterol Goals in Patients with Previous Myocardial Infarction: A Real-World Cross-Sectional Analysis. Arq Bras Cardiol 2024; 121:e20230242. [PMID: 38477763 PMCID: PMC11081093 DOI: 10.36660/abc.20230242] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2023] [Revised: 09/04/2023] [Accepted: 10/25/2023] [Indexed: 03/14/2024] Open
Abstract
BACKGROUND The European Society of Cardiology guidelines recommend an LDL-cholesterol (LDL-C) < 55 mg/dL for patients with established cardiovascular disease. While the Friedewald equation to estimate LDL-C is still widely used, the newer Martin-Hopkins equation has shown greater accuracy. OBJECTIVES We aimed to assess: A) the proportion of patients reaching LDL-C goal and the therapies used in a tertiary center; B) the impact of using the Martin-Hopkins method instead of Friedewald's on the proportion of controlled patients. METHODS A single-center cross-sectional study including consecutive post-myocardial infarction patients followed by 20 cardiologists in a tertiary hospital. Data was collected retrospectively from clinical appointments that took place after April 2022. For each patient, the LDL-C levels and attainment of goals were estimated from an ambulatory lipid profile using both Friedewald and Martin-Hopkins equations. A two-tailed p-value of < 0.05 was considered statistically significant for all tests. RESULTS Overall, 400 patients were included (aged 67 ± 13 years, 77% male). Using Friedewald's equation, the median LDL-C under therapy was 64 (50-81) mg/dL, and 31% had LDL-C within goals. High-intensity statins were used in 64% of patients, 37% were on ezetimibe, and 0.5% were under PCSK9 inhibitors. Combination therapy of high-intensity statin + ezetimibe was used in 102 patients (26%). Applying the Martin-Hopkins method would reclassify a total of 31 patients (7.8%). Among those deemed controlled by Friedewald's equation, 27 (21.6%) would have a Martin-Hopkins' LDL-C above goals. CONCLUSIONS Less than one-third of post-myocardial infarction patients had LDL-C within the goal. Applying the Martin-Hopkins equation would reclassify one-fifth of presumably controlled patients into the non-controlled group.

Characterization and LDL-C management in a cohort of high and very high cardiovascular risk patients: The PORTRAIT-DYS study. Clin Cardiol 2024; 47:e24183. [PMID: 37933175 PMCID: PMC10766132 DOI: 10.1002/clc.24183] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/10/2023] [Revised: 10/23/2023] [Accepted: 10/24/2023] [Indexed: 11/08/2023] Open
Abstract
AIM This study aims to characterize sociodemographic and clinical characteristics, use of lipid-lowering therapies (LLTs), and low-density lipoprotein cholesterol (LDL-C) control in a population with increased cardiovascular (CV) risk. METHODS A cross-sectional observational study that uses electronic health records of patients from one hospital and across 14 primary care health centers in the North of Portugal, spanning from 2000 to 2020 (index date). Patients presented at least (i) 1 year of clinical data before inclusion, (ii) one primary care appointment 3 years before the index date, and (iii) sufficient data for CV risk classification. Patients were divided into three cohorts: high CV risk; atherosclerotic cardiovascular disease (ASCVD) risk equivalents without established ASCVD; evidence of ASCVD. CV risk and LDL-C control were defined by the 2019 and 2016 European Society of Cardiology (ESC)/European Atherosclerosis Society (EAS) dyslipidemia guidelines. RESULTS A total of 51 609 patients were included, with 23 457 patients classified as high CV risk, 19 864 with ASCVD equivalents, and 8288 with evidence of ASCVD. LDL-C control with 2016 ESC/EAS guidelines was 32%, 10%, and 18% for each group, respectively. Considering the ESC/EAS 2019 guidelines control level was even lower: 7%, 3%, and 7% for the same cohorts, respectively. Patients without any LLT prescribed ranged from 37% in the high CV risk group to 15% in patients with evidence of ASCVD. CONCLUSION We found that LDL-C control was very low in patients at higher risk of CV events. An alarming gap between guidelines on dyslipidemia management and clinical implementation persists, even in those at very high risk or with established ASCVD.

Abstract
INTRODUCTION AND OBJECTIVES Current epidemiological data on heart failure (HF) in Portugal derives from studies conducted two decades ago. The main aim of this study is to determine HF prevalence in the Portuguese population. Using current standards, this manuscript aims to describe the methodology and research protocol applied. METHODS The Portuguese Heart Failure Prevalence Observational Study (PORTHOS) is a large, three-stage, population-based, nationwide, cross-sectional study. Community-dwelling citizens aged 50 years and older will be randomly selected via stratified multistage sampling. Eligible participants will be invited to attend a screening visit at a mobile clinic for HF symptom assessment, anthropomorphic assessment, N-terminal pro-B-type natriuretic peptide (NT-proBNP) testing, one-lead electrocardiogram (ECG) and a sociodemographic and health-related quality of life questionnaire (EQ-5D). All subjects with NT-proBNP ≥125 pg/mL or with a prior history of HF will undergo a diagnostic confirmatory assessment at the mobile clinic composed of a 12-lead ECG, comprehensive echocardiography, HF questionnaire (KCCQ) and blood sampling. To validate the screening procedure, a control group will undergo the same diagnostic assessment. Echocardiography results will be centrally validated, and HF diagnosis will be established according to the European Society of Cardiology HF guidelines. A random subsample of patients with an equivocal HF with preserved ejection fraction diagnosis based on the application of the Heart Failure Association preserved ejection fraction diagnostic algorithm will be invited to undergo an exercise echocardiography. CONCLUSIONS Through the application of current standards, appropriate methodologies, and a strong research protocol, the PORTHOS study will determine the prevalence of HF in mainland Portugal and enable a comprehensive characterization of HF patients, leading to a better understanding of their clinical profile and health-related quality of life.

Abstract
INTRODUCTION AND OBJECTIVES Heart failure (HF) has significant morbidity and mortality, and its prevalence will continue to increase in the future. This unfavorable evolution requires reflection as well as recommendations and decisions based on expert critical and strategic appraisal. METHODS In the Acceleration on Heart Failure Empowerment and Awareness - the Portuguese Challenge (ATHENA-PT) study, a range of strategic factors that represent the strengths, weaknesses, threats, and opportunities (SWOT) of HF in Portugal were established. These factors were assessed quantitatively by experts, to create a final SWOT matrix for the management and prevention of HF in Portugal and to outline recommendations. RESULTS For HF management, the panel emphasized the following strategic recommendations: (i) reimbursement of natriuretic peptides testing in primary healthcare; (ii) reimbursement of Doppler assessment in echocardiographic studies and promotion of detailed information in reports; (iii) intervention to improve the prognosis of patients with HF with preserved ejection fraction; (iv) ensuring effective healthcare transition between hospital and ambulatory units, using checklists/protocols; and (v) reinforcement and commitment to the training of primary health physicians and to the cardiac rehabilitation of patients. For the prevention of HF, the following recommendations/proposals were proposed: (i) campaigns to raise awareness of cardiovascular disease risk factors; (ii) promotion of physical exercise and healthy eating; and (iii) avoidance of therapeutic inertia in the management of risk factors. CONCLUSIONS The acknowledgment of various strategic factors and their prioritization by experts made it possible to create and reinforce a range of new strategic recommendations for the management and prevention of HF.

Abstract
ABSTRACT Dual antiplatelet therapy with aspirin and P2Y12 inhibitors in patients with ST-segment elevation myocardial infarction (STEMI) has been shown to be associated with better outcomes. Yet, there is uncertainty regarding the optimal timing for its initiation. We performed a systematic review and meta-analysis of evidence on pretreatment with P2Y12 inhibitors in combination with aspirin in patients with STEMI undergoing primary percutaneous coronary intervention (PCI). We performed a systematic search of electronic databases PubMed, CENTRAL, and Scopus until April 2022. Studies were eligible if they compared P2Y12 inhibitor upstream administration with downstream use in patients with STEMI submitted to PCI. Studies with patients receiving fibrinolysis or medical therapy only were excluded. Outcomes were assessed at the shortest follow-up available. Of 2491 articles, 3 RCT and 16 non-RCT studies were included, with a total of 79,300 patients (66.1% pretreated, 66.0% treated with clopidogrel). Pretreatment was associated with reduction in definite stent thrombosis (odds ratio [OR] 0.61 [0.38-0.98]), all-cause death (OR 0.77 [0.60-0.97]), and cardiogenic shock (OR 0.60 [0.48-0.75]). It was also associated with a lower incidence of thrombolysis in myocardial infarction flow <3 pre-PCI (OR 0.78 [0.67-0.92]). However, incidence of recurrent MI was not significantly reduced (OR 0.93 [0.57-1.52]). Regarding safety, pretreatment was not associated with a higher risk of major bleeding events (OR 0.83 [0.75-0.92]). Pretreatment with dual antiplatelet therapy, including a P2Y12 inhibitor, was associated with better pre-PCI coronary perfusion, lower incidence of definite stent thrombosis, cardiogenic shock, and, possibly, all-cause mortality with no sign of potential harm encountered.

Abstract
Cardiovascular (CV) guidelines stress the need for global intervention to manage risk factors and reduce the risk of major vascular events. Growing evidence supports the use of polypill as a strategy to prevent cerebral and cardiovascular disease, however it is still underused in clinical practice. This paper presents an expert consensus aimed to summarize the data regarding polypill use. The authors consider the benefits of polypill and the significant claims for clinical applicability. Potential advantages and disadvantages, data regarding several populations in primary and secondary prevention, and pharmacoeconomic data are also addressed.

Non-HDL-cholesterol in dyslipidemia: Review of the state-of-the-art literature and outlook. Atherosclerosis 2023; 383:117312. [PMID: 37826864 DOI: 10.1016/j.atherosclerosis.2023.117312] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/19/2023] [Revised: 09/12/2023] [Accepted: 09/12/2023] [Indexed: 10/14/2023]
Abstract
Dyslipidemia refers to unhealthy changes in blood lipid composition and is a risk factor for atherosclerotic cardiovascular diseases (ASCVD). Usually, low-density lipoprotein-cholesterol (LDL-C) is the primary goal for dyslipidemia management. However, non-high-density lipoprotein cholesterol (non-HDL-C) has gained attention as an alternative, reliable goal. It encompasses all plasma lipoproteins like LDL, triglyceride-rich lipoproteins (TRL), TRL-remnants, and lipoprotein a [Lp(a)] except high-density lipoproteins (HDL). In addition to LDL-C, several other constituents of non-HDL-C have been reported to be atherogenic, aiding the pathophysiology of atherosclerosis. They are acknowledged as contributors to residual ASCVD risk that exists in patients on statin therapy with controlled LDL-C levels. Therefore, non-HDL-C is now considered an independent risk factor or predictor for CVD. The popularity of non-HDL-C is attributed to its ease of estimation and non-dependency on fasting status. It is also better at predicting ASCVD risk in patients on statin therapy, and/or in those with obesity, diabetes, and metabolic disorders. In addition, large follow-up studies have reported that individuals with higher baseline non-HDL-C at a younger age (<45 years) were more prone to adverse CVD events at an older age, suggesting a predictive ability of non-HDL-C over the long term. Consequently, non-HDL-C is recommended as a secondary goal for dyslipidemia management by most international guidelines. Intriguingly, geographical patterns in recent epidemiological studies showed remarkably high non-HDL-C attributable mortality in high-risk countries. This review highlights the independent role of non-HDL-C in ASCVD pathogenesis and prognosis. In addition, the need for a country-specific approach to dyslipidemia management at the community/population level is discussed. Overall, non-HDL-C can become a co-primary or primary goal in dyslipidemia management.

Pretreatment with a P2Y12 receptor inhibitor and delay to coronary artery bypass surgery in patients with non-ST segment elevation acute coronary syndrome. Minerva Cardiol Angiol 2023; 71:582-589.

Abstract
BACKGROUND 2020 ESC guidelines for non-ST elevation acute coronary syndromes (NSTE-ACS) recommend against the pretreatment with P2Y12 receptor inhibitors (P2Y12i) in patients undergoing early invasive management (<24 h). The rationale is, in part, to prevent bleeding complications and the delay of coronary artery bypass graft surgery (CABG) in patients with suitable coronary anatomy. This study aimed to analyze the theoretical impact of pretreatment with a P2Y12i on delay to CABG surgery in a real-world population with NSTE-ACS. METHODS Single-center retrospective cohort of consecutive patients with NSTE-ACS undergoing invasive evaluation in 2019. Those with previous CABG or nonobstructive coronary disease were excluded. RESULTS The total cohort included 262 patients (mean age 68±12 years, 69% male, 15% with unstable angina and mean GRACE score 134±35). Median time from FMC to angiography was 2 (1-4) days. Overall, 168 (64%) patients underwent percutaneous coronary intervention, 47 (18%) were proposed for CABG and the remainder received conservative management. All patients considered for CABG received pretreatment with P2Y12i (clopidogrel or ticagrelor). The median time from angiography to CABG was 12 (7-15) days. Six patients experienced recurrent angina (13%) and 2 (4%) died before surgery due to refractory ventricular fibrillation. Those who underwent CABG under P2Y12i effect were more likely to receive blood and platelets transfusions (64.7% vs. 28.6%, P=0.017 and 82.4% vs. 21.4%, P<0.001, respectively), although there were no differences regarding major bleeding. CONCLUSIONS Pretreatment with P2Y12i was a potential but not the sole driver of CABG delay in our cohort. Adopting the new recommendations of withholding pretreatment might decrease this delay, but other factors must be considered.

Diuretic-resistant heart failure and the role of ultrafiltration: A proposed protocol. Rev Port Cardiol 2023; 42:797-803.

Abstract
Acute heart failure (HF) decompensation generally manifests with signs and symptoms of congestion that strongly predict poor poor patient outcome. Loop diuretics are the cornerstone of therapy to counteract fluid overload and are widely used for acute management and chronic stabilization of HF. However, a diminished response to loop diuretics is a common problem, affecting the patient's clinical course and potentially prolonging hospitalization. Diuretic resistance is defined as failure to decongest despite appropriate and escalating loop diuretic therapy. We propose a protocol for the management of diuretic resistance. The initial approach should include an assessment of causes of pseudo-diuretic resistance. Adjustments to loop diuretic therapy, such as increasing doses and frequency of administration and sequential nephron blockade, may be successful. For hospitalized patients with progressive disease there are more invasive methods for fluid removal. Switching from oral to intravenous loop diuretics is essential to avoid variable absorption and for symptomatic relief. Extracorporeal ultrafiltration is also an option since this technique is highly effective at removing plasma fluid from blood. While extracorporeal ultrafiltration is an invasive solution, peritoneal dialysis is a home-based, intermittent therapeutic option that can enable efficient management of fluid overload, preventing HF-related hospital admission, and improving quality of life. As a last resort for fluid removal, a peritoneal dialysis regimen should fully exploit its decongestive properties and should be tailored to the patient's characteristics and clinical needs.

Möbius carbon nanobelts interacting with heavy metal nanoclusters. J Mol Model 2023; 29:277.

Abstract
CONTEXT The interaction between carbon nanostructures and heavy metal clusters is of great interest due to their potential applications as sensors and filters to remove the former from environment. In this work, we investigated the interaction between two types of carbon nanobelts (Möbius-type nanobelt and simple nanobelt) and nickel, cadmium, and lead nanoclusters. Our aim was to determine how both systems interact which would shed light on the potential applications of the carbon nanostructures as pollutant removal and detecting devices. METHODS To investigate the interaction between carbon nanostructures and heavy metal nanoclusters, we utilized the semiempirical tight binding framework provided by xTB software with the GFN2-xTB Hamiltonian. We performed calculations to determine the best interaction site, lowest energy geometries, complexes stability (using molecular dynamics at 298K), binding energy, and electronic properties. We also carried out a topological study to investigate the nature and intensity of the bonds formed between the metal nanoclusters and the nanobelts. Our results demonstrate that heavy metal nanoclusters have a favorable binding affinity towards both nanobelts, with the Möbius-type nanobelt having a stronger interaction. Additionally, our calculations reveal that the nickel nanocluster has the lowest binding energy, displaying the greatest charge transfer with the nanobelts, which was nearly twice that of the cadmium and lead nanoclusters. Our combined results lead to the conclusion that the nickel nanoclusters are chemisorbed, whereas cadmium and lead nanoclusters are physisorbed in both nanobelts. These findings have significant implications for the development of sensor and filtering devices based on carbon and heavy metal nanoclusters.

Exercise Oscillatory Ventilation Improves Heart Failure Prognostic Scores. Heart Lung Circ 2023; 32:949-957. [PMID: 37330375 DOI: 10.1016/j.hlc.2023.04.291] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2022] [Revised: 01/06/2023] [Accepted: 04/02/2023] [Indexed: 06/19/2023]
Abstract
BACKGROUND Several heart failure (HF) prognostic risk scores are available to guide the ideal time for listing candidates for a heart transplant (HTx). The detection of exercise oscillatory ventilation (EOV) during cardiopulmonary exercise testing (CPET) is associated with advanced HF and a worse prognosis, and yet it is not accounted for in these risk scores. Therefore, this study aimed to assess whether EOV further adds prognostic value to HF scores. METHODS A single-centre retrospective cohort study was undertaken of consecutive HF patients with reduced ejection fraction (HFrEF) who underwent CPET from 1996 to 2018. The Heart Failure Survival Score (HFSS), Seattle Heart Failure Model (SHFM), Meta-analysis Global Group In Chronic Heart Failure (MAGGIC), and Metabolic Exercise Cardiac Kidney Index (MECKI) were calculated. The added value of EOV on top of those scores was assessed using a Cox proportional hazard model. The added discriminative power was also assessed by receiver operating characteristic curve comparison. RESULTS A total of 390 HF patients with a median age of 58 (IQR 50-65) years were investigated, of whom 78% were male and 54% had ischaemic heart disease. The median peak oxygen consumption was 15.7 mL/kg/min (IQR 12.8-20.1). Exercise oscillatory ventilation was detected in 153 (39.2%) patients. Over a median follow-up of 2 years, 61 patients died (49 due to a cardiovascular reason) and 54 had a HTx. Exercise oscillatory ventilation independently predicted the composite outcome of all-cause death and HTx. Furthermore, the presence of this ventilatory pattern significantly improved the prognostic performance of both HFSS and MAGGIC scores. CONCLUSION Exercise oscillatory ventilation was often found in a cohort of HF patients with reduced LVEF who underwent CPET. It was found that EOV added further prognostic value to contemporary HF scores, suggesting that this easily obtained parameter should be included in future modified HF scores.

[PMID: 37090089 PMCID: PMC10119631 DOI: 10.1016/j.lanepe.2023.100624] [Citation(s) in RCA: 40] [Impact Index Per Article: 40.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2022] [Revised: 03/14/2023] [Accepted: 03/16/2023] [Indexed: 04/08/2023] Open
Abstract
Background European data pre-2019 suggest statin monotherapy is the most common approach to lipid management for preventing cardiovascular (CV) events, resulting in only one-fifth of high- and very high-risk patients achieving the 2019 ESC/EAS recommended low-density lipoprotein cholesterol (LDL-C) goals. Whether the treatment landscape has evolved, or gaps persist remains of interest. Methods Baseline data are presented from SANTORINI, an observational, prospective study that documents the use of lipid-lowering therapies (LLTs) in patients ≥18 years at high or very high CV risk between 2020 and 2021 across primary and secondary care settings in 14 European countries. Findings Of 9602 enrolled patients, 9044 with complete data were included (mean age: 65.3 ± 10.9 years; 72.6% male). Physicians reported using 2019 ESC/EAS guidelines as a basis for CV risk classification in 52.0% (4706/9044) of patients (overall: high risk 29.2%; very high risk 70.8%). However, centrally re-assessed CV risk based on 2019 ESC/EAS guidelines suggested 6.5% (308/4706) and 91.0% (4284/4706) were high- and very high-risk patients, respectively. Overall, 21.8% of patients had no documented LLTs, 54.2% were receiving monotherapy and 24.0% combination LLT. Median (interquartile range [IQR]) LDL-C was 2.1 (1.6, 3.0) mmol/L (82 [60, 117] mg/dL), with 20.1% of patients achieving risk-based LDL-C goals as per the 2019 ESC/EAS guidelines. Interpretation At the time of study enrolment, 80% of high- and very high-risk patients failed to achieve 2019 ESC/EAS guidelines LDL-C goals. Contributory factors may include CV risk underestimation and underutilization of combination therapies. Further efforts are needed to achieve current guideline-recommended LDL-C goals. Trial registration ClinicalTrials.gov Identifier: NCT04271280. Funding This study is funded by Daiichi Sankyo Europe GmbH, Munich, Germany.

Plant Functional Dispersion, Vulnerability and Originality Increase Arthropod Functions from a Protected Mountain Mediterranean Area in Spring. PLANTS (BASEL, SWITZERLAND) 2023; 12:889. [PMID: 36840238 PMCID: PMC9960503 DOI: 10.3390/plants12040889] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 12/23/2022] [Revised: 02/07/2023] [Accepted: 02/10/2023] [Indexed: 06/18/2023]
Abstract
Plant diversity often contributes to the shape of arthropod communities, which in turn supply important ecosystem services. However, the current biodiversity loss scenario, particularly worrying for arthropods, constitutes a threat for sustainability. From a trait-based ecology approach, our goal was to evaluate the bottom-up relationships to obtain a better understanding of the conservation of the arthropod function within the ecosystem. Specifically, we aim: (i) to describe the plant taxonomic and functional diversity in spring within relevant habitats of a natural protected area from the Mediterranean basin; and (ii) to evaluate the response of the arthropod functional community to plants. Plants and arthropods were sampled and identified, taxonomic and functional indices calculated, and the plant-arthropod relationships analyzed. Generally, oak forests and scrublands showed a higher plant functional diversity while the plant taxonomic richness was higher in grasslands and chestnut orchards. The abundance of arthropod functional groups increased with the plant taxonomic diversity, functional dispersion, vulnerability and originality, suggesting that single traits (e.g., flower shape or color) may be more relevant for the arthropod function. Results indicate the functional vulnerability of seminatural habitats, the relevance of grasslands and chestnut orchards for arthropod functions and pave the way for further studies about plant-arthropod interactions from a trait-based ecology approach.

Clinical outcomes in heart failure with reduced left ventricular ejection fraction and good functional capacity: The illusion of stability. Rev Port Cardiol 2023; 42:89-95. [PMID: 36228834 DOI: 10.1016/j.repc.2021.10.012] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2021] [Revised: 09/15/2021] [Accepted: 10/25/2021] [Indexed: 11/06/2022] Open
Abstract
BACKGROUND Heart failure (HF) remains a prevalent syndrome with significant morbidity and mortality. Optimal drug and device therapies are crucial to reduce the risk of death or HF admission. Yet, less symptomatic patients with good functional capacity are often perceived as having a low risk of adverse events and their attending physicians may suffer from prescription inertia or refrain from performing therapy optimization. Maximum or peak oxygen consumption (pVO2) assessed during cardiopulmonary exercise testing (CPET) is often used as a prognosis indicator and surrogate marker for functional capacity. Our goal was to assess clinical outcomes in a seemingly low risk HF population in Weber class A (pVO2>20 mL/kg/min) with reduced left ventricular ejection fraction (LVEF). METHODS Single-center retrospective observational study enrolling consecutive HF patients with LVEF<40% (HFrEF) performing CPET between 2003 and 2018. Those with pVO2 >20 mL/kg/min were included. The primary endpoint was a composite of all-cause death or HF hospitalizations at two years after CPET. We also assessed the rates of N-terminal pro b-type natriuretic peptide (NT-proBNP) elevations at baseline. RESULTS Seventy-two patients were included (mean age of 53±10 years; 86% male; 90% NYHA I-II; median LVEF 32%; median pVO2 24 mL/kg/min). At baseline, 93% had an NT-proBNP level >125 pg/mL (median NT-proBNP 388 [201-684] pg/mL). Overall, seven patients (10%) met the primary endpoint: three died (4%) and five (7%) had at least one HF admission. Among those who died, only one patient had an HF admission during follow up. CONCLUSION In a clinically stable HFrEF population with good functional capacity, persistent neurohormonal activation was present in the majority, and one in ten patients died or had a HF admission at two years' follow-up. These findings support the urgent need to motivate clinicians to pursue optimal drug uptitration even in less symptomatic patients.

Beyond exercise oscillatory ventilations: the prognostic impact of loop gain in heart failure. Eur J Prev Cardiol 2023; 30:zwad021. [PMID: 36707994 DOI: 10.1093/eurjpc/zwad021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/09/2022] [Revised: 01/07/2023] [Accepted: 01/24/2023] [Indexed: 01/29/2023]
Abstract
Exercise oscillatory ventilation (EOV) is a strong prognostic marker in patients with heart failure (HF) and left ventricular (LV) dysfunction. This phenomenon can be explained through a single quantitative measurement of ventilatory instability, the loop gain. Therefore, we aimed to evaluate whether loop gain could be a better tool than subjective EOV evaluation to identify HF patients with a higher risk of major cardiovascular complications. This was a single-center retrospective study that included patients with left ventricular ejection fraction (LVEF) ≤ 50% consecutively referred for cardiopulmonary exercise testing (CPET) from 2016-2020. Loop gain was measured through computational evaluation of the minute ventilation graph. Of the 250 patients included, the 66 that presented EOV also had higher values of loop gain, when compared to patients without EOV. Those with both EOV and higher loop gain had more severe HF, with higher NT-proBNP and VE/VCO2 slope as well as lower peak VO2 and LVEF. On multivariable analysis, loop gain was strongly correlated with the composite endpoint of cardiovascular death, urgent heart transplantation, urgent left ventricular assist device implantation or HF hospitalization, even after correcting for peak VO2, LVEF, VE/VCO2 slope and NT-proBNP. Presence of EOV was not prognostically significant in this analysis. Loop gain is an objective parameter that quantifies ventilatory instability and showed to have a strong prognostic value in a cohort of patients with HF and LVEF ≤ 50%, outperforming the classification of EOV.

Cost-Effectiveness of the CNIC-Polypill Strategy Compared With Separate Monocomponents in Secondary Prevention of Cardiovascular and Cerebrovascular Disease in Portugal: The MERCURY Study. JOURNAL OF HEALTH ECONOMICS AND OUTCOMES RESEARCH 2022; 9:134-146. [PMID: 36475278 PMCID: PMC9687308 DOI: 10.36469/001c.39768] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 09/04/2022] [Accepted: 10/24/2022] [Indexed: 06/17/2023]
Abstract
Background: Cardiovascular (CV) diseases remain a leading and costly cause of death globally. Patients with previous CV events are at high risk of recurrence. Secondary prevention therapies improve CV risk factor control and reduce disease costs. Objectives: To assess the cost-effectiveness of a CV polypill strategy (CNIC-Polypill) compared with the loose combination of monocomponents to improve the control of CV risk factors in patients with previous coronary heart disease or stroke. Methods: A Markov model cost-utility analysis was developed using 4 health states, SMART risk equation, and 3-month cycles for year 1 and annual cycles thereafter, over a lifetime horizon from the perspective of the National Health System in Portugal (base case). The NEPTUNO study, Portuguese registries, mortality tables, official reports, and the literature were consulted to define effectiveness, epidemiological costs, and utility data. Outcomes were costs (estimated in 2020 euros) per life-year (LY) and quality-adjusted LY (QALY) gained. A 4% discount rate was applied. Alternative scenarios and one-way and probabilistic sensitivity analyses tested the consistency and robustness of results. Results: The CNIC-Polypill strategy in secondary prevention provides more LY and QALY, at a higher cost, than monocomponents. The incremental cost-utility ratio is €1557/QALY gained. Assuming a willingness-to-pay threshold of €30 000/QALY gained, there is a 79.7% and a 44.4% probability of the CNIC-Polypill being cost-effective and cost-saving, respectively, compared with the loose combination of monocomponents. Results remain consistent in the alternative scenarios and robust in the sensitivity analyses. Discussion: The model reflects increments in the number of years patients would live and in quality of life with the CNIC-Polypill. The clinical effectiveness of the CNIC-Polypill strategy initially demonstrated in the NEPTUNO study has been recently corroborated in the SECURE trial. The incremental cost of the CNIC-Polypill strategy emerges slightly above the comparator, but willingness-to-pay estimates and sensitivity analyses indicate that the CNIC-Polypill strategy is consistently cost-effective compared with monocomponents and remains within acceptable affordability margins. Conclusion: The CNIC-Polypill is a cost-effective secondary prevention strategy. In patients with histories of coronary heart disease or stroke, the CNIC-Polypill more effectively controls CV risk factors compared with monocomponents.

Abstract
Abstract
Double antiplatelet therapy (DAPT) with both aspirin and P2Y12 inhibitors in patients with STEMI has been shown to be associated with better clinical outcomes. Yet, there is uncertainty regarding the optimal timing for its initiation. This study is a systematic review and meta-analysis of the current evidence on pretreatment with P2Y12 inhibitors in patients with STEMI submitted to primary percutaneous coronary intervention (PCI).
We performed a systematic search of electronic databases Pubmed, CENTRAL and Scopus until April/22. Studies were considered eligible if they were comparing P2Y12 inhibitor upstream administration vs. downstream use in patients with STEMI submitted to PCI. Studies with patients treated with fibrinolysis or medical therapy only were excluded. Outcomes were assessed at the shortest follow-up available.
Out of 2336 articles, 18 studies were included (3 RCT and 17 non-RCT), with a total of 79300 patients (52439 in the pretreatment arm). Pretreatment was associated with a reduction in definite stent thrombosis (OR 0.59 [0.37–0.94]), all-cause death (OR 0.77 [0.60–0.97]) and cardiogenic shock (OR 0.60 [0.48–0.75]). It was also associated with lower incidence of TIMI flow < 3 pre-PCI (OR 0.78 [0.67–0.92]). However, it was not associated with a significant reduction in recurrent MI (OR 0.93 [0.57–1.52]). Regarding safety outcomes, pretreatment was not associated with higher risk of major bleeding events (OR 0.83 [0.75–0.92]).
Pretreatment with DAPT, including a P2Y12 inhibitor, was associated with better pre-PCI coronary perfusion, lower risk for definite stent thrombosis, cardiogenic shock, and all-cause mortality. No sign of potential harm from this approach was encountered.

Abstract
Abstract
Background
ESC guidelines for non-ST elevation acute coronary syndromes (NSTE-ACS) recommend against P2Y12 pre-treatment receptor inhibitors (P2Y12i) in patients undergoing early invasive management (< 24 h). The rationale is, in part, to prevent bleeding complications and the delay of coronary artery bypass graft surgery (CABG) in patients with suitable anatomy. This study aims to analyze the impact of P2Y12i pre-treatment on delay to CABG surgery in a real-world population with NSTE-ACS.
Methods
Single-centre retrospective cohort of consecutive patients with NSTE-ACS undergoing invasive evaluation in 2019. Those with previous CABG (n = 31) or non-obstructive coronary disease (n = 57) were excluded.
Results
Total cohort included 262 patients (mean age 68 ± 12 years, 69% male, 15% with unstable angina and mean GRACE score 134 ± 35). Median time from first medical contact to angiography was 2 (1–4) days. Overall, 168 (64%) patients underwent percutaneous coronary intervention, 47 (18%) were proposed for CABG and the remainder received conservative management. All patients considered for CABG received pre-treatment with P2Y12i, either clopidogrel or ticagrelor. Median time from angiography to CABG was 12 (7–15) days. Six patients experienced recurrent angina (13%) and 2 (4%) died before surgery due to refractory ventricular fibrillation. Those who underwent CABG under P2Y12i effect were more likely to receive blood and platelets transfusions (64.7% vs. 28.6%, P = 0.017 and 82.4% vs. 21.4%, P < 0.001, respectively), although there were no differences regarding major bleeding.
Conclusion
Pre-treatment with P2Y12i was a potential driver of CABG delay in our cohort. In the real-world, adopting the new recommendations of withholding pre-treatment might decrease this delay.

Abstract
Abstract
Background
Adult Congenital Heart Disease (ACHD) patients at increased risk for thromboembolic events are often treated with oral anticoagulation. While vitamin-K antagonists have been the agent of choice for decades, the use of non-vitamin K oral anticoagulants (NOAC) is increasing. We aimed to assess the safety and effectiveness of NOAC in ACHD patients at our centre.
Methods
This is a single-centre study enrolling all patients with ACHD treated with a NOAC from inception to November 2021. Data was collected using a standardized questionnaire applied to all patients by means of a telephone visit, in parallel with a detailed retrospective chart review. The endpoints of interest included thromboembolic and haemorrhagic events, defined as per the standardized International Society on Thrombosis and Haemostasis (ISTH) scale.
Results
Overall, 36 ACHD patients were enrolled [mean age 53±15 years; female sex – 66.7%; previous stroke – 33.3%; median HAS-BLED and CHA2DS2-VASc score – 1 (1–2) and 3 (2–5), respectively], predominantly with moderate or complex congenital defects (52.7%), of whom 14, 8, 8 and 4 were treated with rivaroxaban, apixaban, edoxaban and dabigatran, respectively. Two-thirds had their first NOAC prescription in the latest 3 years (Figure 1). The most common indication for anticoagulation was atrial fibrillation or flutter (77.8%). Over a median time of 36 (18–63) months on NOAC treatment, there were no patients with thromboembolic events, whilst 13 (36.1%) had a haemorrhagic event – annualized event rate of 12.0 (6.9–24.1%). All bleeding events were minor, most often self-limited gingival haemorrhage or epistaxis (n=7) or menorrhagia (n=3). Nasal cautery was needed to treat recurrent epistaxis in 3 patients, whilst 3 other required oral iron supplementation. The strongest predictor of any haemorrhage was a prior cardiovascular hospitalization (HR 3.88; p=0.027).
Conclusions
The use of NOAC in ACHD patients has been increasing in our centre, with encouraging results. The present findings suggest that NOAC are safe and may be effective for thromboembolic event prevention in heterogeneous forms of ACHD.

Further prognostic stratification in patients with oscillatory ventilation with exercise: is there more to it than just ups and downs? Eur Heart J 2022.

Abstract
Abstract
Introduction
Exercise Oscillatory Ventilation (EOV) has numerous definitions, but the common foundation is the presence of an oscillatory phenomenon of the ventilation/minute graph with a given amplitude and frequency. Recently, it was proposed that the presence of a delay in O2 consumption (VO2) peak to minute ventilation (VE) peak during ventilatory oscillation was a predictor of worse prognosis in patients with heart failure (HF) and left ventricular ejection fraction (LVEF) <50%.
The aim of this work was to assess whether these characteristics add further prognostic value to the subset of patients with HF and EOV.
Methods
This was a single-centre retrospective cohort of consecutive patients with HF and LVEF <50% that underwent cardiopulmonary exercise testing (CPET) from 2016–2020. EOV was defined as per Vainshelboim 2017 (≥3 consecutive cyclic fluctuations of ventilation during exercise, average amplitude over 3 ventilatory oscillations ≥5L and an average length of three oscillatory cycles 40s to 140s). The presence of EOV was evaluated by 3 independent observers after observing a VE over time plot. For the creation of this plot, data was collected as a rolling average of 5 consecutive breaths. The presence of EOV was established if at least 2 observers agreed on the classification.
Afterwards, a second graph was plotted, with both VO2 and VE over time and the mean delay between VO2 peak to VE peak during EOV was manually calculated (Figure 1).
The primary endpoint was a composite of time to all-cause death, heart transplantation or left ventricular assistance device (LVAD) implantation.
Results
Of the 285 patients, 78 (27%) were classified as having EOV. These HF patients were mostly male (75%) with a mean age of 58±12 years, mean LVEF 31±10% with 63% having ischemic etiology. During a median follow up of 27 (17 to 43) months, 4 LVAD implantations, 12 heart transplantations and 18 deaths. The rate of primary outcome was 19% and 36% at 1- and 2-years. The amplitude, frequency, and maximum number of EOV cycles were not associated with the development of the primary endpoint. Only the mean delay between VO2 peak to VE peak during EOV was predictive of time to primary endpoint, even when adjusted for peak VO2 and VE VCO2 slope (adjusted HR 1.06 95% CI 1.009–1.114) (Figure 2). The cut-off of 5 seconds for mean VO2 peak to VE peak delay seems to be the most useful to predict the primary outcome at 2 years, with a sensitivity of 48% and specificity of 84%.
Conclusion
This novel parameter seems to be the only EOV-related parameter to enable further stratification of prognosis in a cohort of patients with severe HF, with the best cut-off of mean delay between VO2 peak to VE peak during EOV being 5 seconds.

Abstract
Abstract
Introduction
Dual antiplatelet therapy (DAPT) with aspirin and a P2Y12 inhibitor is the cornerstone of antithrombotic therapy in patients with ST-segment elevation myocardial infarction (STEMI). Yet, there is uncertainty surrounding the optimal timing for the initiation of the P2Y12 inhibitor. This study aims to evaluate the effectiveness and safety of P2Y12 pretreatment by means of a systematic review and meta-analysis of studies in primary percutaneous coronary intervention (PCI) in STEMI.
Methods
We performed a systematic search of electronic databases Pubmed, CENTRAL and Scopus until March of 2021. Studies were considered eligible if they were: a) comparing P2Y12 inhibitor upstream administration vs. treatment during PCI; b) patients enrolled for STEMI and submitted to primary PCI. Studies with patients treated with fibrinolysis or medical therapy only were excluded. Major clinical outcomes included 30-day occurrence of all-cause death, definite stent thrombosis and re-infarction. Thrombolysis in myocardial infarction (TIMI) flow-grade pre-PCI and post-PCI, in-hospital cardiogenic shock and major bleeding events were analysed.
Results
Out of 2193 articles, 18 studies were included (1 randomized clinical trial [RCT] and 17 observational studies [non-RCT]), with a total of 76,836 patients, 52,181 in the pretreatment arm. At 30 days, pretreatment was associated with a reduction in definite stent thrombosis (1 RCT & 4 Non-RCT: OR 0.40; 95% CI 0.18–0.90), but no significant reduction in all-cause death (1 RCT & 7 Non-RCT: OR 0.77; 95% CI 0.56–1.04) or re-infacrtion (1 RCT & 4 Non-RCT: OR 0.73; 95% CI 0.49–1.09). Regarding in-hospital outcomes, pretreatment showed a significant reduction in the occurrence of cardiogenic shock (5 Non-RCT: 0.62; 95% CI 0.51–0.79), major bleeding events (1 RCT & 14 Non-RCT: 0.83; 95% CI 0.75–0.92) and in the number of patients with TIMI flow <3 postPCI (1 RCT & 8 Non-RCT: 0.82; 95% CI 0.73–0.93). Pretreatment was not associated with lower number of patients with TIMI flow <3 pre-PCI (1 RCT & 5 Non-RCT: 0.85; 95% CI 0.66–1.09).
Conclusion
Pretreatment with DAPT, including a P2Y12 inhibitor, was associated with lower risk for definite stent thrombosis and cardiogenic shock, but was not associated with lower all-cause death or re-infarction.

Abstract
Abstract
Background
Transthyretin Amyloid Cardiomyopathy (ATTR-CM) is an under-diagnosed condition often presenting with Heart Failure (HF). We aimed to assess a cohort of patients with ATTR-CM and HF, focusing on the centre strategies to identify new cases, prognosticate and tailor treatment.
Methods
We conducted an all-comers single-centre prospective registry of consecutive patients with HF due to ATTR-CM followed in our centre from November 2019 to 2021. As per site protocol, diagnosis is established according to the algorithm by Gilmore et al. and all patients are assessed in our HF outpatient clinic at least twice yearly with systematic electronic chart data collection. We evaluated disease-modifying treatment and compliance with the current European Guidelines and CHAD-STOP management. A summary of this program is presented in the central figure.
Results
Overall, 60 patients were included (mean age 83±7 years; 80% male). ATTR-CM was confirmed by the non-invasive algorithm in all but 8 patients, in whom endomyocardial biopsy was positive. Of those undergoing genetic testing (n=30), 7 (23%) presented with the hereditary form of ATTR-CM (4 Val50Met and 3 Val142Ile mutations). The initial presentation was most often HF (n=43), atrial fibrillation (n=9), or “incidental” myocardial uptake on 99mTc-HMDP bone scintigraphy (grade 2) performed for cancer staging (n=5). Beta-blockers were reduced or stopped in 40 (67%) patients, all of whom improved in NYHA class and/or NT-proBNP (>30% reduction) at 1–3 months. Tafamidis 61mg was started in 22 patients and 15 more currently await approval. Those initiated on or referred to tafamidis 61mg (n=37) had less severe HF, as per NYHA (class I-II – 94 vs. 50%, p=0.033) and performance status (e.g. Karnofsky score 80–100 – 79 vs. 21%, p=0.010). Of those already on tafamidis (n=22), NYHA class remained stable or improved in all but 1 patient. In the year following vs. preceding treatment there was 2 vs. 3 total HF hospitalizations. No drug-related severe adverse events were reported. Over a 2-year follow-up, 14 (23.3%) patients died, of whom 1 was on tafamidis (compassionate use for 19 months).
Conclusions
ATTR-CM recognition is improving in our dedicated rare disease program, possibly due to the implementation of several alert pathways. The identification of the disease at an earlier stage allows targeted treatment, compliant with the recommendations. Nonetheless, the rarity of this disease and the required expertise for its optimal management argues in favour of a national strategic plan based on referral centres for ATTR-CM.

Abstract
Background
Aborted cardiac arrest (ACA) during the acute ischaemic phase is a relatively frequent but often undervalued complication of acute myocardial infarction (AMI). The aim of this study was to evaluate the clinical and prognostic impact of aborted cardiac arrest in AMI patients and investigate its correlation with infarct size.
Methods
We conducted a single-centre retrospective study enrolling consecutive patients admitted for AMI, from January 2016 to December 2018. ACA was defined as the need for advanced life support measures and defibrillation, either out-of-hospital or in-hospital, up until culprit vessel revascularisation. Infarct size was estimated using peak serum troponin T, impact on left ventricular ejection fraction (LVEF ≤50%) and echocardiographic wall motion index (WMI). Clinical outcomes included cardiogenic shock (SCAI C or more), need for mechanical circulatory support (MCS), major bleeding events (BARC ≥3) during in-hospital phase and all-cause mortality during follow-up.
Results
A total of 571 patients were included (65±13 years old, 72% male). Overall, 237 had anterior STEMI, 39 patients (6,8%) suffered ACA (21 out of hospital), 60 progressed into cardiogenic shock throughout the hospitalisation, 7 needed MCS, and 52 had BARC ≥3 bleeding. During a mean follow-up of 32 months, 96 patients died.
ACA was significantly associated with higher peak serum troponin T (4802 [1950; 9420] vs 2659 [555; 6708] ng/L – p=0.004), higher proportion of patients with reduced or mildly reduced LVEF (60% vs. 36.5%, p=0.018) and higher WMI (1.7 [1.4; 2.3] vs. 1.5 [1.2; 1.8], p=0.016). Moreover, ACA was also associated with higher risk of cardiogenic shock occurrence (64.1% vs. 6.6%, p<0.001 – OR 25.357 (12.115–53.073)), higher need for MCS (7.9% vs 0.8%, p<0.001 – OR 11.271 (2.427–52.343)) and higher incidence of BARC ≥3 bleeding events (28.2% vs. 8.4%, p<0.001 – OR 4.705 (2.185–10.128)) – Table 1.
On univariate Cox regression, ACA showed significant association with all cause death, which remained highly significant after multivariable adjustment (OR 2.431 (1.181; 5.002); p=0.016).
Conclusion
The occurrence of aborted cardiac arrest in patients with AMI was associated with increased morbidity and mortality. This may be driven by a larger area of arrhythmia prone ischemic myocardium.

Abstract
Abstract
Background
Exercise Oscillatory Ventilation (EOV) during Cardiopulmonary Exercise Test (CPET) predicts prognosis in patients with Heart Failure (HF). In these patients, O2 consumption (VO2) oscillations have also been described, possibly secondary to circulatory delay. We hypothesize that in clinically meaningful EOV, cardiac output variation is mirrored by VO2 oscillation, which is then chronologically followed by a similar oscillation in minute ventilation (VE) (Figure 1). Accordingly, we aimed to assess whether this new definition surpassed that of classical EOV.
Methods
This is a single-centre cohort study of consecutive patients undergoing CPET from 2016 to 2018. Patients with LVEF >50% were excluded. CPET was performed on a treadmill to the limit of tolerance. Data was collected as a rolling average of 20 seconds and a composite VE/time and VO2/time plot was created. Classical EOV was defined as three or more regular oscillations of the VE graph with a minimal average amplitude of five litters. The addition of exercise VO2-to-VE peak-to-peak ventilation asynchrony (EVA) to the previous criteria fulfilled the new definition. The primary endpoint was a composite of time to all-cause death, heart transplantation or HF hospitalization.
Results
Overall, 177 patients were enrolled (mean age 58±11 years, LVEF 34±9%), of whom 35 had EOV and 17 had EVA. Compared to those without EVA, patients with EVA had markers of more severe HF. During a median follow-up of 32 (21–42) months, 55 patients met the primary outcome (32 all-cause deaths, 15 heart transplants, 47 HF hospitalizations). In multivariate analysis, EVA was associated with a 2.5-fold increased risk of events (HR 2.489; 95% CI: 1.302–4.759; p=0.006), adjusted for peak VO2, VE to CO2 production ratio (VE/VCO2 slope) and LVEF. EVA outperformed EOV in predicting the primary endpoint at 1 year, with a similar sensitivity and higher specificity (96.2 vs. 83.2%). The rate of events between the subgroup of patients without EVA was similar regardless of presence of EOV, contrasting with a higher rate in the EVA subgroup (Figure 2).
Conclusion
EVA is a strong predictor of hard outcomes in a broad population with HF. The new definition may outperform that of classical EOV. The incidence and prognostic value of EVA in the management algorithm and risk stratification of patients with HF is worth being further explored.

Looking beyond left ventricular ejection fraction – a new multiparametric CMR score to refine the prognostic assessment of HF patients. Eur Heart J 2022.

Abstract
Abstract
Background
Cardiac magnetic resonance (CMR) is recommended in Heart Failure (HF) to assess myocardial structure and function. Recently, the quantification of pulmonary congestion and skeletal muscle mass using CMR have been shown to predict adverse events in HF, but a tool integrating this information is currently unavailable. The purpose of this study was to develop and test a new multiparametric CMR-derived score.
Methods
We conducted a single-center retrospective study of consecutive HF patients with left ventricular ejection fraction (LVEF) <50% who underwent CMR. Several CMR parameters with known prognostic value were assessed, including: LVEF, Lung Water Density (LWD), Pectoralis Major Muscle (PMM) area, and presence of Late Gadolinium Enhancement. PMM area was outlined at the level of the carina – Figure 1A, B – and LWD was defined as the lung-to-liver signal ratio multiplied by 0.7, as previously described. Both parameters were measured in standard HASTE images - Figure 1C. The primary endpoint was a composite of all-cause death or HF hospitalization. Using the Cox regression Hazard Ratios of designated variables, a risk score was developed.
Results
Overall, 436 patients were included. During a median follow-up of 27 (17–37) months, 43 (9.9%) patients died and 57 (13.2%) had at least one hospitalization for HF. LVEF, LWD and PMM were independent predictors of the primary endpoint and were included in the CMR-HF score – Figure 2. The annual rate of events increased from 4.7 to 7.5 and 20.0% from lowest to highest tertile of the score. Roughly half of the events (54%) occurred in patients in the highest tertile of the CMR-HF score. In multivariate analysis, the new score independently predicted the primary endpoint (HR per 5 points: 1.54; 95% CI: 1.21–1.97; p<0.001) even after adjustment for age, body mass index, NYHA class, NT-proBNP, estimated glomerular filtration rate, presence of implantable cardioverter-defibrillator, and ischemic etiology.
Conclusions
This novel multidimensional CMR-HF score, combining easily obtainable data on left ventricular pump failure, lung congestion and muscular wasting, is a promising tool identifying HF patients with an LVEF <50% at higher risk of death or HF hospitalization.

CAD in kidney transplant recipients: a real-world assessment pre-ISCHEMIA-CKD. Eur Heart J 2022.

Abstract
Abstract
Background
The ISCHEMIA-CKD trial has shown that an initial invasive strategy, as compared to conservative treatment, did not reduce the risk of death and non-fatal myocardial infarction, nor did it improve quality-of-life in patients with advanced chronic kidney disease (CKD) and coronary artery disease (CAD) with moderate-to-severe ischemia. Similar findings were reported in patients with CKD enlisted for kidney transplantation (KT). We aimed to evaluate screening and treatment CAD strategies in patients who ultimately underwent KT at our center.
Methods
This is a single-center study of consecutive patients who received a KT from 2015 to 2020. Obstructive CAD was defined whenever one of the following criteria was met: lesion with a stenosis >70% (or >50%, if left main disease) or CAD requiring revascularization, as per the Heart Team discussion. CAD evaluation refers to non-invasive or invasive coronary angiography and/or stress testing, irrespective of clinical scenario.
Results
A total of 324 patients underwent KT [mean age 55±12 years; 65.1% male; CKD most often due to hypertensive or diabetic nephropathy and polycystic kidney disease – 41.8%; median time from renal replacement therapy (RRT) to KT – 60 (40–88) months]. A flow-chart summarizing CAD diagnosis over time is depicted in Figure 1. Overall, 119 (36.7%) patients had CAD evaluation prior to KT, of whom 21 underwent myocardial revascularization – 8, 12 and 1 patients with acute coronary syndrome (ACS), chronic coronary syndrome (CCS) and silent ischaemia, respectively. At a median time of 46 (25–66) months after KT, 36 (11.1%) more patients had CAD evaluation, of whom 8 underwent percutaneous myocardial revascularization – 6 and 2 for ACS and CCS, respectively. Those with obstructive CAD were older (64 vs 54 years-old; p<0.001), with a higher burden of cardiovascular (CV) risk factors (p<0.001) and more likely to have had a CV death (9.5 vs. 1.0%; p=0.025) or CV hospitalization (38.1 vs. 13.4%; p=0.007). CAD status (revascularized vs. non-revascularized) was not associated with improved major outcomes at follow-up. We found no strong predictors of CAD requiring revascularization post-KT, including time from RRT to KT. There were no patients with refractory angina, left main disease or reduced left ventricular ejection fraction (<40%) in need of myocardial revascularization over follow-up.
Conclusions
Obstructive CAD was uncommon in our cohort of patients who received a KT, most of whom with asymptomatic or mildly (monthly angina) symptomatic CCS or non-fatal ACS. These findings, together with the most recent evidence, may argue against routine CAD screening in all patients being enlisted for KT. Notwithstanding, randomized evidence is eagerly awaited to further guide treatment decisions in the post-ISCHEMIA-CKD era.

Abstract
AIMS Heart failure (HF) is the most frequent cause of hospital admission among patients 65 years or older. Patients hospitalized for acutely decompensated chronic HF and 'de novo' acute heart failure (AHF) continue to experience unacceptably high post-discharge readmission and mortality rates. METHODS AND RESULTS Until recently, trials had failed to improve outcome in patients with AHF irrespective of ejection fraction with exception of sodium-glucose co-transporter 2 inhibitors (SGLT2i) that improved clinical outcomes in patients hospitalized for AHF in the Study to Test the Effect of Empagliflozin in Patients Who Are in Hospital for Acute Heart Failure (EMPULSE) and in the Effect of Sotagliflozin on Cardiovascular Events in Patients With Type 2 Diabetes Post Worsening Heart Failure (SOLOIST-WHF) trials. CONCLUSIONS This document reviews the potential utility of SGLT2i in patients hospitalized for AHF.

Abstract
BackgroundFiber-poor diets are linked to a reduction in gut microbiota diversity and gut barrier integrity, which is thought to promote the susceptibility to chronic inflammatory disorders1,2. We have previously shown that dietary resistant starch (RS) improves lupus-like disease in a murine model of SLE3 through the modulation of microbiota composition. If similar dysbiotic microbial community structures exist in subsets of SLE patients and if a RS intervention may be efficacious in those patients remains unclear.ObjectivesTo test if the dietary RS content in SLE and SLE-related antiphospholipid syndrome (APS) affect gut microbial taxa associated with SLE in published cohorts to date.MethodsWe obtained stool and blood samples as well as diet history for up to 3 visits (0, 4 and 8 weeks) from 12 SLE (n=28) and 15 APS (n=44) patients as well as 20 controls (n=48) as previously published4-6. Microbiota composition was defined by 16S rRNA V4 region sequencing on the Illumina platform and correlated with dietary fiber content extracted from a diet questionnaire. We used the FDA reference list to determine dietary RS contents in patients` regular diets and defined RS quantities as being low if less than 2.5 g/day and as medium if 2.5 to 15 g/day. None of the patients achieved high RS greater than 15 g/day. Mann-Whitney or Kruskal-Wallis tests were performed to compare bacteria relative abundances among the different groups. Simple linear regression was performed to relate the bacterial abundance to RS content and other metadata.ResultsMedium intake of RS was associated with beneficial Bifidobacterium spp. in SLE patients (p=0.016) but not APS (p=0.509). Instead, APS patients who consumed medium quantities of RS in their diets had less gut bacterial taxa that are capable of producing cardiolipins (among them Collinsella; p=0.009) and Ruminococcus gnavus (p=0.0142), a species previously associated with lupus nephritis7. A recent Japanese metagenome-wide study8 associated Streptococcus spp. and related redox reaction genes with SLE, which may also affect oxidative processes in APS9. We therefore also explored Streptococcus levels in SLE and APS patients and found unexpectedly a significant reduction of streptococci in a subset of APS (p=0.004) but not SLE patients (p=0.451) in medium compared to low RS dietary content. Streptococcus abundance was correlated with both Collinsella (R2=0.3141; p=<0,0001) and Ruminococcus gnavus (R2=0.1687; p=<0,0056) in APS patients.ConclusionMedium compared to low RS quantities in the regular diets of SLE and APS patients were associated with unique alterations in gut microbial community structures. Bifidobacterium increased in SLE patients with diets containing medium RS whereas APS patients with medium RS carried less cardiolipin-synthesizing taxa and lupus-related pathobionts. In particular, Streptococcus species recently strongly associated with SLE and redox reactions in Japanese patients in a metagenome-wide study8, were significantly suppressed in APS patients on medium RS diets. This modulatory effect was not seen in SLE patients or control subjects consuming medium RS. Together, these findings support distinct dietary effects on autoimmune gut microbiomes depending on the disease state. They also suggest potential beneficial effects of increased RS content on gut microbiota in SLE and APS patients. Fully resolving gut microbial signatures and clinical characteristics in these patients may identify the ideal subset to benefit from an interventional pilot trial with RS.References[1] Thorburn et al., 2014, Immunity 19, 833-842[2] Ruff et al, 2020, Nat Rev Microbiol 18, 521-538[3] Zegarra-Ruiz et al., 2019, Cell Host Microbe 25, 113-127[4] Greiling et al., 2018, Science Transl Med 10, 1–15[5] Manfredo Vieira et al, 2018, Science 359, 1156-1161[6] Ruff et al., 2019, Cell Host Microbe 26, 1–14[7] Azzouz et al., 2019, Ann Rheum Dis 78, 947–956[8] Tomofuji et al., 2021, Ann Rheum Dis 80, 1575–1583[9] Giannakopoulos and Krilis, 2013, New Engl J Med 368, 1033-1044AcknowledgementsThe work was supported by grants from the National Institutes of Health (NIH) (R01AI118855, T32AI07019), Arthritis National Research Foundation, Arthritis Foundation, Lupus Research Alliance, and Maren Foundation.Disclosure of InterestsMárcia Pereira: None declared, Iryna Kulyk: None declared, Sylvio Redanz: None declared, William E Ruff: None declared, Teri M.

Abstract
The mission statement of the European Society of Cardiology (ESC) is "to reduce the burden of cardiovascular disease". The ESC is the leading scientific society for cardiovascular health care professionals across Europe and increasingly the world. Recognising the need for democratisation of education in cardiology, the ESC has for many years embraced the digital world within its education programme. As in all areas of medicine, the COVID-19 pandemic required an agile response to be able to continue to provide not only a digital congress but also education, training and assessment in an almost totally digital world. In this paper we will describe the digital learning activities of the ESC, the successes and the challenges of the transformation that has taken place in the last 18 months as well as an overview of the vision for education, training and assessment in the post-COVID digital era. We understand the need to provide a portfolio of educational styles to suit a diverse range of learners. It is clear that digital CME provides opportunities but it is likely that it will not entirely replace in-person learning. In planning for the future, we regard the provision of digital CME as central to fulfiling our mission.

Validation of a novel framework defining the acceptable standard of care for heart failure with reduced ejection fraction. Eur Heart J 2021.

Abstract
Abstract
Background
In heart failure with reduced ejection fraction (HFrEF), uptitration of neurohormonal antagonists to trial-proven doses shown to reduce mortality is challenging and seldomly achieved in clinical practice. A major reason for underdosing of these agents is the lack of a clear description of what constitutes an acceptable standard of care in HFrEF. To address this limitation, a novel framework for describing the physician adherence to evidence-based treatment was recently proposed. The aim of our study was to evaluate and validate the proposed framework in a real-world population of patients with HFrEF.
Methods
A cohort of patients with HFrEF, defined as left ventricular ejection fraction (LVEF) <40%, under treatment with neurohormonal antagonists for at least 3 months were retrospectively identified at a tertiary hospital's Heart Failure Clinic. Demographic, clinical, echocardiographic and treatment data were assessed. Patients were divided in three strata for each neurohormonal antagonist, according to the proposed framework: Status I – patients receiving target doses or the highest tolerated dose; Status II – use of subtarget doses for reasons unrelated to clinically important intolerance; and Status III – not receiving the drug at any dose. The prognostic value of each strata was assessed for all-cause mortality.
Results
A total of 408 patients (mean age 68±12 years, 78% male, 63% ischemic etiology) were included. The median LVEF was 31% (IQR 25–36) and most patients were in NYHA class II or III [210 (51.5%) and 163 (40%), respectively]. Medical therapy is described in Table 1. During a median follow-up of 3.3 years (IQR 1.4–5.6), 210 patients died. On univariable analysis, achieving Status I of beta-blocker (BB) therapy (HR: 0.50; 95% CI: 0.32–0.81; P=0.004) or ACEi/ARB (HR: 0.56; 95% CI: 0.36–0.86; P=0.012) was associated with reduced all-cause mortality. The mortality of patients in Status II of BB or ACEi/ARB was similar to the mortality of those not receiving the drug (HR for BB: 0.90; 95% CI: 0.53–1.52; P=0.69 and HR for ACEi/ARB: 0.71; 95% CI: 0.42–1.18; P=0.182) – figure 1. Achieving Status I of BB remained independently associated with reduced mortality after adjustment for several clinical and echocardiographic confounders (n=13) (adjusted HR: 0.59; 95% CI: 0.35–0.98; P=0.041).
Conclusions
In this real-world population of patients with HFrEF, the vast majority of patients were in Status I of BB and ACEi/ARB therapy. Achieving Status I of BB therapy seems to be associated with reduced mortality, even after adjustment for several markers of disease severity, highlighting the need for uptitration of medical therapy to maximal tolerated doses according to trial-proven regimens.

Abstract
Abstract
Background
The burden of CV disease is a health and economic challenge to societies that is expected to grow in future years due to an increased prevalence in CV risk factors. Adequate management and appropriate therapy positively modify risk factors and, consequently, improve outcomes and cost-effectiveness of care. The CNIC-polypill has demonstrated in real-life, clinical effectiveness studies, its superiority over monocomponents in improving the lipidic parameters and in reduction of blood pressure in secondary CV prevention patients.
Purpose
To assess the cost-effectiveness of the CNIC-polypill (acetylsalicylic acid 100mg, atorvastatin 20/40mg, ramipril 2.5/5/10mg) compared to usual care with individual monocomponents for the secondary prevention of CV events in patients with a history of coronary heart disease (CHD) based on control of CV risk factors.
Methods
A Markov cost-effectiveness model (1-year cycles; 4 health states: stable disease, subsequent CHD, subsequent stroke, death; payer perspective; direct medical costs; lifetime horizon; 4% discount rate) based on changes in TC (10,1% reduction), HDL-c (7.4% increment) and SBP (2.6% reduction) obtained from the NEPTUNO* – a real-life, clinical effectiveness study conducted in Spain – was set for Portugal (base case). The probability of transition between health states was based on the SMART risk equation (S0, t=10= 0.8107). Cost-effectiveness was calculated for a hypothetical population (n=1,000) that replicated the characteristics of the population in the proACS registry, comprised of Portuguese patients with previous CHD. Systematic reviews identified epidemiological, costs, utility and mortality data. Outcomes were costs (€, 2020), life years (LY) and quality adjusted LY (QALY) gained.
Results
In patients with a history of CHD, the incremental cost of the CNIC-polypill strategy reaches €365,527, while preventing 35 recurrent CHD events and 17 subsequent strokes. In women and men with previous CHD, the incremental cost reaches €392,529 and €354,444 respectively while preventing recurrent 47 and 30 CHD events and 19 and 16 subsequent strokes respectively. The ICER is €5,130/LY gained for the overall population, €5,768/LY gained for women and €4,884/LY gained for men. The ICUR is €5,332/QALY gained in total, €5,817/QALY gained for women and €5,137/QALY gained for men. Assuming a willingness-to-pay (WTP) threshold of €30,000/QALY gained, there is 76.1% chances in total, 75.8% in women and 76.9% in men for the CNIC-polypill to be cost-effective and 27.8% chances overall, 27.7% in women and 25.5% in men of it being cost saving compared to usual care.
Conclusion
The CNIC-polypill seems to be a cost-effective strategy in men and women compared to usual care with monocomponents for the secondary prevention of CV disease based on improved control of risk factors. A larger reduction in the number of recurrent events is seen in women compared to men at a slightly higher cost.

Abstract
Abstract
Background
Right Ventricular (RV) dysfunction is a well-recognized prognostic marker in the natural history of left-sided Heart Failure (HF). Common experience dictates that structural and functional evaluation are often seemingly discrepant. We aimed to evaluate the correlation between RV function by transthoracic echocardiography (TTE) and Right Heart Catheterization (RHC) parameters, and their prognostic value in patients with HF.
Methods
We designed a retrospective single-centre study of patients with advanced HF referred to TTE and RHC as part of Heart Transplant candidacy evaluation, from 2010 to 2019. Pulmonary Hypertension (PH) was defined by a mean pulmonary artery pressure (mPAP) ≥25mmHg. Patients with PH other than Group II (WHO) PH were excluded. In appropriate cases, vasodilator challenge with inhaled NO was performed. The primary endpoint was a composite of death, heart transplant or HF hospitalization at 6 months.
Results
The cohort was comprised of 68 patients (mean age 56±11 years, 73.5% male, ischaemic HF 44.1%). Most patients had PH (n=61) and TTE evidence of RV dysfunction (n=46). The strongest correlations between RHC and TTE parameters were moderate at best – mPAP, pulmonary capillary wedge pressure and central venous pressure with E/A ratio (Pearson r 0,461, 0,533 and 0,543, respectively; p<0.05); and RV stroke work index and mPAP with non-invasive estimated systolic pulmonary artery (PA) pressure (Pearson r 0,483 and 0,481, respectively; p<0.05). Over a median follow-up of 26 (12–42) months, 53 patients had a primary endpoint event, of whom 36 within 6 months. The best model integrating data from structural and functional assessment to predict the primary endpoint included the systolic PA pressure to stroke volume ratio – i.e. PA elastance (HR per 0.10 units: 2.817; 95% CI 1.030–1.338; p=0.016) – and RV free wall longitudinal strain (HR per −1%: 0.792; 95% CI 0.656–0.956; p=0.015). ROC curve analysis disclosed the best cut-off values as follows: 1.3 (sensitivity 77.2%, specificity 65.6%) and −18% (sensitivity 10.7%, specificity 86.4%), respectively.
Conclusion
In a cohort of patients with advanced HF, who were potential candidates for heart transplantation, RV dysfunction was often noted. The model with highest accuracy to predict the primary outcome integrated RV structural with functional data. Additional studies are warranted to define well-validated scores useful in the algorithmic therapeutic decision of advanced HF.

Abstract
Abstract
Background
Left Ventricular (LV) Global Function index (LVGFi) is a parameter that combines data from global systolic performance and volumetric anatomical information, measurable by non-contrast Cardiac Magnetic Resonance (CMR). We aimed to evaluate whether LVGFi predicts major cardiovascular outcomes and outperforms LV ejection fraction (LVEF) in Heart Failure (HF).
Methods
We conducted a retrospective single-centre study of consecutive patients with HF who were referred to and had a LVEF <50% at CMR. Other than inadequate images for endocardial or epicardial border delineation, there were no exclusion criteria. LVEF was determined by 3D measurement. LVGFi was calculated as the LV stroke volume to the LV global volume ratio (Figure 1). The primary endpoint was a composite of time to all-cause death or HF hospitalization.
Results
The cohort was comprised of 433 HF patients (mean age 64±12 years, 74.1% male, ischaemic HF 53.1%, NYHA I-II 83.9%) with a mean LVEF of 33.5±10.0% and LVGFi of 22.8±7.4%. Over a median follow-up of 27 (17–37) months, 85 (19.6%) met the primary endpoint and 42 (9.7%) died. Patients with an event of the primary endpoint had markers of more severe HF, as noted by a reduced functional capacity (NYHA I-II: 63.5 vs. 89.0%; p<0.001) and increased natriuretic peptides [NT-proBNP: 2664 (1022–27242) vs. 791 (337–7258); p<0.001). Likewise, CMR showed higher LV volumes (e.g., LV end-diastolic volume index: 137±50 vs. 120±43mL/m2; p=0.001) and reduced LV performance indices, namely LVEF (29.2±10.6 vs 34.5±9.6%; p<0.001) and LVGFi (19.8±7.4 vs 23.6±7.3%; p<0.001). Both LVEF and LVGFi independently predicted the primary endpoint in multivariate analysis (separately imputed into a model adjusted for NYHA, NT-proBNP and creatinine). The LVEF model was more powerful than that of LVGFi. Similarly, LVGFi did not provide incremental prognostic information over LVEF in c-statistics analysis (0.653 vs. 0.622; p=0.645) (Figure 2).
Conclusion
While LVGFi independently predicted major outcomes in patients with HF and LVEF <50%, it did not surpass LVEF. Our findings contrast to those demonstrating LVGFi as a powerful variable that outperforms LVEF in hypertrophic cardiomyopathy, cardiac amyloidosis, and healthy subjects at risk of developing structural heart disease. We hypothesize that LVGFi might be primarily useful in the prognostic stratification of patients with preserved LVEF.

Abstract
Abstract
Background
The SMART-REACH score (SRS) was developed to predict the risk of major adverse cardiovascular events in ambulatory patients with established cardiovascular disease, although it has not been extensively validated. Patients at higher risk of recurrent ischemic events may benefit from novel, more intensive treatment options, and earlier identification of these patients can potentially improve outcomes.
Purpose
We aimed to validate the SRS and evaluate its performance in a population recently admitted with acute coronary syndrome.
Methods
In this single-centre retrospective cohort, we included 320 patients aged 45 to 80 years, who were discharged following admission for an acute coronary syndrome between 2016 and 2018. To calculate the SRS for each patient, we considered clinical data on admission (age, gender, smoking, diabetes, prior history of vascular disease, heart failure or atrial fibrillation), lipid values obtained within the first 24 hours of hospitalization, serum creatinine level at baseline and once the patient was deemed clinically stable, and discharge medication. The outcome of interest was defined as stroke, myocardial infarction or cardiovascular death (MACE) at two years of follow-up. SRS was assessed for discrimination and calibration.
Results
Mean age was 63±9 years, and 240 (75%) were male. There was high prevalence of cardiovascular risk factors: 71% had hypertension, 32% had diabetes mellitus, 42% were active smokers and 25% had previously established cardiovascular disease. The outcome of interest was observed in 38 patients (22 cardiovascular deaths, 6 strokes and 14 myocardial infarctions). SRS showed good discrimination of the estimated MACE risk with overall C-statistic of 0.646 (95% CI, 0.554–0.737, p=0.004) (picture 1) and calibration (p-value for the goodness-of-fit test of 0.544). The global estimated risk of MACE at 2-years was 4.8% (3.8%-6.8%). The expected/ observed ratio was 0.56 for the occurrence MACE (picture 2).
Conclusions
Over the first two years after discharge from an acute coronary syndrome, one of every 8 patients developed a potentially fatal recurrent ischemic event. The SRS performed reasonably well in discriminating those at highest risk of MACE, suggesting that this score may help select patients at discharge for ad initium more intensive pharmacological therapy.

Abstract
To assess whether a simplified cardiac magnetic resonance (CMR)–derived lung water density (LWD) quantification predicted major events in Heart Failure (HF). Single-centre retrospective study of consecutive HF patients with left ventricular ejection fraction (LVEF) < 50% who underwent CMR. All measurements were performed on HASTE sequences in a parasagittal plane at the right midclavicular line. LWD was determined by the lung-to-liver signal ratio multiplied by 0.7. A cohort of 102 controls was used to derive the LWD upper limit of normal (21.2%). The primary endpoint was a composite of time to all-cause death or HF hospitalization. Overall, 290 patients (mean age 64 ± 12 years) were included. LWD measurements took on average 35 ± 4 s, with good inter-observer reproducibility. LWD was increased in 65 (22.4%) patients, who were more symptomatic (NYHA ≥ III 29.2 vs. 1.8%; p = 0.017) and had higher NT-proBNP levels [1973 (IQR: 809–3766) vs. 802 (IQR: 355–2157 pg/mL); p < 0.001]. During a median follow-up of 21 months, 20 patients died and 40 had ≥ 1 HF hospitalization. In multivariate analysis, NYHA (III–IV vs. I–II; HR: 2.40; 95%-CI: 1.30–4.43; p = 0.005), LVEF (HR per 1%: 0.97; 95%-CI: 0.94–0.99; p = 0.031), serum creatinine (HR per 1 mg/dL: 2.51; 95%-CI: 1.36–4.61; p = 0.003) and LWD (HR per 1%: 1.07; 95%-CI: 1.02–1.12; p = 0.007) were independent predictors of the primary endpoint. These findings were mainly driven by an association between LWD and HF hospitalization (p = 0.026). A CMR-derived LWD quantification was independently associated with an increased HF hospitalization risk in HF patients with LVEF < 50%. LWD is a simple, reproducible and straightforward measurement, with prognostic value in HF.

Evaluation of contemporary treatment of high- and very high-risk patients for the prevention of cardiovascular events in Europe - Methodology and rationale for the multinational observational SANTORINI study. ATHEROSCLEROSIS PLUS 2021; 43:24-30. [PMID: 36644508 PMCID: PMC9833224 DOI: 10.1016/j.athplu.2021.08.003] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 07/21/2021] [Accepted: 08/12/2021] [Indexed: 01/18/2023]
Abstract
Background and aims Clinical practice before 2019 suggests a substantial proportion of high and very high CV risk patients taking lipid-lowering therapy (LLT) would not achieve the new LDL-C goals recommended in the 2019 ESC/EAS guidelines (<70 and < 55 mg/dL, respectively). To what extent practice has changed since the last ESC/EAS guideline update is uncertain, and quantification of remaining implementation gaps may inform health policy. Methods The SANTORINI study is a multinational, multicentre, prospective, observational, non-interventional study documenting patient data at baseline (enrolment) and at 12-month follow-up. The study recruited 9606 patients ≥18 years of age with high and very high CV risk (as assigned by the investigators) requiring LLT, with no formal patient or comparator groups. The primary objective is to document, in the real-world setting, the effectiveness of current treatment modalities in managing plasma levels of LDL-C in high- and very high-risk patients requiring LLT. Key secondary effectiveness objectives include documenting the relationship between LLT and levels of other plasma lipids, high-sensitivity C-reactive protein (hsCRP) and overall predicted CV risk over one year. Health economics and patient-relevant parameters will also be assessed. Conclusions The SANTORINI study, which commenced after the 2019 ESC/EAS guidelines were published, is ideally placed to provide important contemporary insights into the evolving management of LLT in Europe and highlight factors contributing to the low levels of LDL-C goal achievement among high and very high CV risk patients. It is hoped the findings will help enhance patient management and reduce the burden of ASCVD in Europe.

Abstract
Background:It has been published that the presence of NXP2 autoantibodies presents a risk for calcinosis in patients with JDM.Objectives:To investigate the incidence of calcinosis and response to the treatment in NXP2 positive JDM patients with calcinosis.Methods:The study design is a retrospective, multinational, multicenter study. Data on gender, race, age at disease onset and age at disease diagnosis, age at inclusion in the study, clinical presentation, muscle function tests, laboratory results, imaging, data on treatment and outcome of disease were collectedResults:we collected 26 patients (19 F, 7 M) with JDM and positive NXP2 antibodies. Fourteen patients were white, eight asian, three black and one Hispanic ethnicity. The mean age at disease presentation was 6.5 years (SD 3.7), the median diagnosis delay was 4 months (range 0.5- 27 months). Patients were divided in two groups (A and B) based on the presence of calcinosis.Eleven patients (42%) developed calcinosis (group A) in the course of the disease, 10 females and 1 male. Four patients already had calcinosis at presentation, 1 developed after 4 months, and 6 developed calcinosis later in disease course (median 2 years, range 0,8- 7,8). Four patients developed lipodystrophy in group A (1 in group B). In group A, 3 patients developed skin ulcerations (1 in group B), 2 patients had polyarthritis (1 in group B), 2 patients had gut involvement (1 in group B) and 1 patient had lung involvement (2 in group B).The mean age at disease presentation (5.2 / 7.5 y) and mean CK level (1548.6 / 1811.6 U/L) were lower in group A. The platelet count (306.5 / 258 109/L), and mean values of AST (111.4 / 103.8 U/L), ALT (72.2 / 50.8 U/L), LDH (1048.3 / 808 IU/L), and IgG (11.8 / 9.9 g/L) were higher in group A. However, the differences were not statistically significant. ANA antibodies were positive in 9/11 in group A and 12/15 in group B. One patient in group A was also positive for anti-MDA5 antibody. The data on muscle strength measurement (MMT/CMAS) were available only in a few patients.Treatments used for patients with calcinosis includes, methotrexate and glucocorticosteroids (GCS) (all patients), hydroxychloroquine (9), IVIG (7), cyclosporine (4), bisphosphonate (4), MMF (5), rituximab (4), cyclophosphamide (1), abatacept (1) and TNF alpha blocker (1).Disease outcome (by evaluation of the treating physician) was excellent in 4, good in 2, stable in 2 and poor in 3 patients. None of the patients from group B had a poor disease outcome. Patients with excellent disease outcomes from group A were treated with GCS and methotrexate (4), hydroxychloroquine (3), IVIG (1) and cyclosporine (1). Out of two patients who had good outcomes, one was additionally treated with MMF, bisphosphonates and rituximab and the second was treated with cyclophosphamide and rituximab. One patient with calcinosis at the presentation (age 4 years) was treated also with anti-TNF alpha therapy which not only stopped progression but partially dissolved the calcinosis. However, after 2 years of anti-TNF alpha therapy the calcinosis start to progress and the therapy was changed to MMF and rituximab, which stopped the progression of calcinosis.Conclusion:Our preliminary results showed that calcinosis occurred in 42% of NXP2 positive JDM patients. Children with calcinosis were treated with several combinations of drugs. In four cases, rituximab and in one case, for limited time of 2 years, anti-TNF alpha agent, were used successfully.References:[1]Chung MP, Richardson C, Kirakossian D, Orandi AB, Saketkoo LA, et al.

Background
The cardiovascular (CV) polypill has consistently demonstrated cost-effectives in decreasing the risk of CV disease in patients in secondary prevention. Previous pharmacoeconomic studies addressed improvements in adherence as a driver of health gains. This economic assessment focuses on the implications of improved control of risk factors with the polypill as observed in clinical practice.
Purpose
To assess the cost-effectiveness of a fixed-dose combination polypill (ASA 100mg, atorvastatin 20/40mg, ramipril 2.5/5/10mg) strategy for the secondary prevention of CV and cerebrovascular events in adults with a history of coronary heart disease (CHD) or stroke compared to usual care with monocomponents.
Methods
A Markov cost-effectiveness model (1-year cycles; 4 health states: stable disease, subsequent CHD, subsequent stroke, death; payer perspective; direct medical costs; lifetime horizon; 4% discount rate) based on changes in CV risk factors (total cholesterol, 18.3% reduction; high density lipoprotein cholesterol, 2.1% increment; systolic blood pressure, 11.46% reduction) obtained from a real-life effectiveness study was set for Portugal. The probability of transition between health states was based on the SMART risk equation. Cost-effectiveness was calculated for two cohorts (n = 1,000) of secondary prevention patients with previous CHD or stroke. Systematic reviews, Portuguese registries, mortality tables and official reports were searched to identify effectiveness, epidemiological, costs and utility data. Outcomes were costs (€, 2020) per life year (LY) and Quality Adjusted LY (QALY) gained. One-way (OWA) and probabilistic (PSA) sensitivity analyses tested consistency. Assumptions were validated by experts.
Results
In the CHD cohort, the incremental cost-effectiveness ratio for the polypill strategy (ICER) is 2,402 €/LY and the incremental cost-utility ratio (ICUR) is 2,328 €/QALY. Incremental cost reaches 278,927 € (polypill, 13,198,506 €; monocomponents: 12,919,579 €) with less subsequent CV events (552.31 vs 641.88) and CV deaths (102.4 vs 118.68). Assuming a willingness-to-pay (WTP) threshold of 30.000 €/QALY gained, the PSA shows a 81.4% probability for the polypill to be cost-effective and 39.1% chances to be costs saving compared to usual care. In the stroke cohort, the ICER is 386 €/LY and the ICUR is 553 €/QALY. Incremental costs are 34,178 € (polypill, 10,138,807 €; monocomponents: 10,104,629 €) with less subsequent CV events (481.99 vs 564.50) and CV deaths (101.00 vs. 117.23) with the polypill. There is a 75.9% probability for the polypill to be cost-effective and 49.5% chances to be costs saving.
Conclusion
The CV polypill is a cost-effective secondary prevention strategy compared to usual care with monocomponents. Its ICER is well below acceptable thresholds in both CV and cerebrovascular disease patients. It reduces the number of recurrent events at a moderately higher cost compared to monocomponents.

Background
Risk equations (RE) are crucial to individualise estimates and properly adjust preventive treatments in patients with previous cardiovascular (CV) disease. RE are also routinely incorporated into health economic assessments but it is unknown if the cost-effectiveness results vary according to the RE applied.
Purpose
To determine the cost-effectiveness of a CV polypill (ASA 100mg, atorvastatin 20/40mg and ramipril 2.5/5/10mg) strategy compared to usual practice of combining monocomponents in the prevention of recurrent events in patients with previous coronary heart disease (CHD) or stroke applying two different CV RE: SMART and FRAMINGHAM, respectively.
Methods
A Markov cost-effectiveness model (1-year cycles; 4 health states: stable disease, subsequent CHD, subsequent stroke; death; payer perspective; direct medical costs; lifetime horizon; 4% discount rate) was developed for Portugal. Transition probability between health states was based on the SMART RE and an adaptation for secondary CV prevention of the FRAMINGHAM RE, respectively. Cost-effectiveness was calculated for a mixed cohort of secondary prevention patients (weighed post-CHD: 57.9%; post-stroke: 42.1%). Systematic literature reviews, Portuguese registries, mortality tables and official reports ware used to identify effectiveness, epidemiological, costs and utility data. Outcomes were costs (€, 2020) per life year (LY) and Quality Adjusted Life Year (QALY) gained. One-way (OWA) and probabilistic (PSA) sensitivity analyses tested the consistency of results. Assumptions were validated by experts.
Results
Applying the SMART RE, the incremental cost-effectiveness ratio (ICER) is 1,555€/LY gained and the incremental cost-utility ratio (ICUR) is 1,785€/QALY gained for the polypill strategy. The incremental costs of adopting the polypill strategy are 171,378€. Recurrent CV events (550.68 vs 642.13) and CV deaths (106.05 vs 122.81) are also less frequent with the polypill strategy compared with monocomponents. Assuming a willingness-to-pay (WTP) threshold of 30.000 €/QALY gained, there is a 77.80% probability for the polypill strategy to be cost-effective and 43.00% chances to be costs saving when used in a mixed cardiovascular and cerebrovascular disease population. Applying the FRAMINGHAM RE, the ICER is 998€/LY gained and the ICUR is 1,242€/QALY. The incremental costs amount 175,122€. Recurrent CV events (452.66 vs 563.48) and CV deaths (104.77 vs 127.32) are less frequent with the polypill strategy. The PSA shows a 99.5% probability for the polypill strategy to be cost-effective and 46.8% chances to be costs saving.
Conclusion
Both risk equations result in comparable results on the cost-effectiveness of interventions for the secondary prevention of CV disease. The polypill strategy remains cost-effective compared to the common practice of using individual monocomponents concomitantly, reducing recurrent CV events at a moderately higher cost.

Assessing proportionate and disproportionate functional mitral regurgitation with individualized thresholds. Eur Heart J Cardiovasc Imaging 2021; 23:431-440.

Abstract
AIMS The concept of proportionate/disproportionate functional mitral regurgitation (FMR) has been limited by the lack of a simple way to assess it and by the paucity of data showing its prognostic superiority. The aim of this study was to evaluate the prognostic value of an individualized method of assessing FMR proportionality. METHODS AND RESULTS We retrospectively identified 572 patients with at least mild FMR and reduced left ventricular ejection fraction (<50%) under medical therapy. To determine FMR proportionality status, we used an approach where a simple equation determined the individualized theoretical regurgitant volume (or effective regurgitant orifice area) threshold associated with haemodynamically significant FMR. Then, we compared the measured with the theoretical value to categorize the population into non-severe, proportionate, and disproportionate FMR. The primary endpoint was all-cause mortality. During a median follow-up of 3.8 years (interquartile range: 1.8-6.2), 254 patients died. The unadjusted mortality incidence per 100 persons-year rose as the degree of FMR disproportionality worsened. On multivariable analysis, disproportionate FMR remained independently associated with all-cause mortality [adjusted hazard ratio: 1.785; 95% confidence interval (CI): 1.249-2.550; P = 0.001]. The FMR proportionality concept showed greater discriminative power (C-statistic 0.639; 95% CI: 0.597-0.680) than the American (C-statistic 0.583; 95% CI: 0.546-0.621; P for comparison <0.001) and European guidelines (C-statistic 0.584; 95% CI: 0.547-0.620; P for comparison <0.001). When added to any of the before-mentioned guidelines, FMR proportionality also improved risk stratification by reclassifying patients into lower and higher risk subsets. CONCLUSION Disproportionate FMR is independently associated with all-cause mortality and improves the risk stratification of current guidelines.
