Treatment and outcomes of patients with chronic lung disease and acute myocardial infarction: Insights from the nationwide AMIS plus registry. Eur J Clin Invest 2024; 54:e14193. [PMID: 38481088 DOI: 10.1111/eci.14193] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/12/2023] [Revised: 02/25/2024] [Accepted: 02/25/2024] [Indexed: 05/15/2024]
Abstract
BACKGROUND Limited data are available on patients with chronic lung disease (CLD) presenting with acute myocardial infarction (AMI). We aimed to analyse baseline characteristics, treatment and outcome of those patients enrolled in the Swiss nationwide prospective AMIS Plus registry. METHODS All AMI patients enrolled between January 2002 and December 2021 with data on CLD, as defined in the Charlson Comorbidity Index, were included. The primary endpoints were in-hospital mortality and major adverse cardiac and cerebrovascular events (MACCE), defined as all-cause death, reinfarction and cerebrovascular events. Baseline characteristics, in-hospital treatments and outcomes were analysed using descriptive statistics and logistic regression. RESULTS Among 53,680 AMI patients enrolled during this time, 5.8% had CLD. Compared with patients without CLD, CLD patients presented more frequently with non-ST-elevation myocardial infarction (MI) and type 2 MI (12.8% vs. 6.5%, p < 0.001). With respect to treatment, CLD patients were less likely to receive P2Y12 inhibitors (p < 0.001) and less likely to undergo percutaneous coronary interventions (68.7% vs. 82.5%; p < 0.001). In-hospital mortality declined in AMI patients with CLD over time (from 12% in 2002 to 7.3% in 2021). Multivariable regression analysis showed that CLD was an independent predictor for MACCE (adjusted OR was 1.28 [95% CI 1.07-1.52], p = 0.006). CONCLUSION Patients with CLD and AMI were less likely to receive evidence-based pharmacologic treatments, coronary revascularization and had a higher incidence of MACCE during their hospital stay compared to those without CLD. Over 20 years, in-hospital mortality was significantly reduced in AMI patients, especially in those with CLD.

Quantifying Hemodynamic Cardiac Stress and Cardiomyocyte Injury in Normotensive and Hypertensive Acute Heart Failure. Biomedicines 2024; 12:1099. [PMID: 38791061 PMCID: PMC11118007 DOI: 10.3390/biomedicines12051099] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2024] [Revised: 04/23/2024] [Accepted: 05/08/2024] [Indexed: 05/26/2024] Open
Abstract
BACKGROUND The characterization of the different pathophysiological mechanisms involved in normotensive versus hypertensive acute heart failure (AHF) might help to develop individualized treatments. METHODS The extent of hemodynamic cardiac stress and cardiomyocyte injury was quantified by measuring the B-type natriuretic peptide (BNP), N-terminal proBNP (NT-proBNP), and high-sensitivity cardiac troponin T (hs-cTnT) concentrations in 1152 patients presenting with centrally adjudicated AHF to the emergency department (ED) (derivation cohort). AHF was classified as normotensive with a systolic blood pressure (SBP) of 90-140 mmHg and hypertensive with SBP > 140 mmHg at presentation to the ED. Findings were externally validated in an independent AHF cohort (n = 324). RESULTS In the derivation cohort, with a median age of 79 years, 43% being women, 667 (58%) patients had normotensive and 485 (42%) patients hypertensive AHF. Hemodynamic cardiac stress, as quantified by the BNP and NT-proBNP, was significantly higher in normotensive as compared to hypertensive AHF [1105 (611-1956) versus 827 (448-1419) pg/mL, and 5890 (2959-12,162) versus 4068 (1986-8118) pg/mL, both p < 0.001, respectively]. Similarly, the extent of cardiomyocyte injury, as quantified by hs-cTnT, was significantly higher in normotensive AHF as compared to hypertensive AHF [41 (24-71) versus 33 (19-59) ng/L, p < 0.001]. A total of 313 (28%) patients died during 360 days of follow-up. All-cause mortality was higher in patients with normotensive AHF vs. patients with hypertensive AHF (hazard ratio 1.66, 95%CI 1.31-2.10; p < 0.001). Normotensive patients with a high BNP, NT-proBNP, or hs-cTnT had the highest mortality. The findings were confirmed in the validation cohort. CONCLUSION Biomarker profiling revealed a higher extent of hemodynamic stress and cardiomyocyte injury in patients with normotensive versus hypertensive AHF.

Abstract
INTRODUCTION Heart failure with preserved left ventricular ejection fraction (HFpEF) is a common and very important disease entity because of its association with frequent repeat hospitalization and high mortality. Hallmarks of the underlying pathophysiology include a small left ventricular cavity due to concentric remodeling, impaired left ventricular compliance and left atrial dysfunction. This leads to an increase in left atrial and pulmonary pressure on exertion and in advanced stages of the disease already at rest with consecutive exertional dyspnea and exercise intolerance. Additional cardiovascular mechanisms including atrial fibrillation, chronotropic incompetence and coronary artery disease as well as non-cardiac co-morbidities contribute to a variable extent to the clinical picture. The diagnostic work-up is demanding and complex but the concepts have significantly improved during the last years. The study results of the Sodium Glucose cotransporter-2 inhibitors (SGLT-2-inhibitors) have revolutionized the treatment of HFpEF. In the present article, we provide an overview about the current understanding of the pathophysiology of HFpEF, the principles of the diagnostic pathways and a summary of the intervention studies in the field, and we propose an approach for the treatment in clinical practice.

Pleural effusion in severe aortic stenosis: marker of an adverse haemodynamic constellation and poor prognosis. ESC Heart Fail 2024; 11:893-901. [PMID: 38200702 DOI: 10.1002/ehf2.14666] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2023] [Revised: 11/25/2023] [Accepted: 12/18/2023] [Indexed: 01/12/2024] Open
Abstract
AIM Pleural effusion (PE) is a common chest radiography (CXR) finding in patients with advanced cardiac disease. The pathophysiology and clinical value of PE in this setting are incompletely defined. We aimed to assess the haemodynamic correlates and prognostic impact of PE in patients with severe aortic stenosis (AS). METHODS AND RESULTS We studied 471 patients (mean age 74 ± 10 years) with severe AS (indexed aortic valve area 0.42 ± 0.12 cm2/m2, left ventricular ejection fraction 58 ± 12%) undergoing right heart catheterization and upright CXR prior to aortic valve replacement (AVR). Two radiologist independently evaluated all CXR for the presence of bilateral PE, unilateral, or no PE, blinded to any other data. There were 49 (10%) patients with bilateral PE, 32 (7%) patients with unilateral PE, and 390 (83%) patients with no PE. Patients with bilateral PE had the highest mean right atrial pressure, mean pulmonary artery wedge pressure (mPAWP), and pulmonary vascular resistance, and had the lowest stroke volume index while those with unilateral PE had intermediate values. In the multivariate analysis, mPAWP was an independent predictor of any PE and bilateral PE. After a median (interquartile range) post-AVR follow-up of 1361 (957-1878) days mortality was highest in patients with bilateral PE (2.7 times higher than in patients without PE), whereas patients with unilateral PE had similar mortality as those without PE. CONCLUSIONS In severe AS patients, the presence of PE, particularly bilateral PE, is a marker of a poor haemodynamic constellation. Bilateral PE is associated with a substantially increased post-AVR mortality.

Pulmonary and Systemic Hemodynamics in Patients with Hyperthyroidism. Am J Med 2024; 137:350-357. [PMID: 38104644 DOI: 10.1016/j.amjmed.2023.11.023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/04/2023] [Revised: 11/28/2023] [Accepted: 11/29/2023] [Indexed: 12/19/2023]
Abstract
BACKGROUND There is an association between hyperthyroidism and pulmonary hypertension. However, the prevalence of pulmonary hypertension in hyperthyroidism and the underlying mechanisms are incompletely defined. METHODS Consecutive patients with severe hyperthyroidism, mostly due to Graves disease, were included in this single-center study. Echocardiographic assessment of pulmonary hemodynamics was performed at the time of hyperthyroidism diagnosis (baseline) and after normalization of thyroid hormones (follow-up; median 11 months). In a subset of patients, right heart catheterization and noninvasive assessment of central hemodynamics was performed. RESULTS Among all 99 patients, 31% had pulmonary hypertension at baseline. The estimated systolic pulmonary artery pressure correlated significantly with the estimated left ventricular filling pressure (E/e'). The invasively measured systolic pulmonary artery pressure correlated well with the estimated systolic pulmonary artery pressure. Cardiac output, E/e', left and right ventricular dimensions were significantly reduced from baseline to follow-up, whereas the estimated pulmonary vascular resistance did not differ. Diastolic blood pressure was significantly higher at follow-up, with no change in systolic blood pressure. The central systolic blood pressure, however, exhibited a trend for a reduction at follow-up, while the pulse wave velocity was significantly lower at follow-up. CONCLUSIONS Approximately one-third of patients with hyperthyroidism have evidence of pulmonary hypertension. Our data suggest that an increased cardiac output and left ventricular filling pressure are the main mechanisms underlying the elevated systolic pulmonary artery pressure in hyperthyroidism, whereas there is no evidence of significant pulmonary vascular disease.

Abstract
AIMS To evaluate the prevalence of heart failure (HF) in patients with diabetes in tertiary care, and the implementation of sodium-glucose co-transporter 2 inhibitor (SGLT2i). METHODS Between 28.09.2020 and 31.03.2022, patients enrolled in the Swiss Diabetes Registry at one study centre were screened for HF based on the recommendations by the European Society of Cardiology. Indicated patients were referred for echocardiography and a clinical evaluation of HF, further stratified by preserved (HFpEF), mildly reduced (HFmrEF), and reduced (HFrEF) left ventricular ejection fraction. RESULTS In total, 534 patients were screened (31.5%, type 1 diabetes (T1D); 59.7%, type 2 diabetes (T2D); 8.8%, other forms). Overall, HF was present in 11.2% (HFpEF, 56.7%; HFmrEF, 11.7%; HFrEF, 31.7%). Prevalence by diabetes type was 2.4%, T1D; 16.0%, T2D; and 10.6%, other forms. Of the identified cases, 40.0% were previously diagnosed and 60.0% were diagnosed as a result of the screening. Of the 24 patients with previously known HF, 50.0% were prescribed SGLT2i (including 2 out of 3 patients with HFrEF). CONCLUSIONS The fact that most cases of HF were previously undiagnosed and treatment with SGLT2i could be improved highlights the need to increase awareness of HF among healthcare professionals treating patients with diabetes.

ECG left ventricular hypertrophy in aortic stenosis: Relationship with cardiac structure, invasive hemodynamics, and long-term mortality. Clin Cardiol 2024; 47:e24155.

Abstract
BACKGROUND In aortic stenosis (AS), left ventricular hypertrophy (LVH) is the response to pressure overload and represents the substrate for a maladaptive cascade, the so-called AS-related cardiac damage. We hypothesized that in AS patients electrocardiogram (ECG) LVH not only predicts echocardiography LVH but also other noninvasive and invasive markers of cardiac damage and prognosis after aortic valve replacement (AVR). METHODS In 279 patients with severe AS undergoing ECG, echocardiography, and cardiac catheterization before AVR, the Sokolow-Lyon index, the Cornell product, the Romhilt-Estes score, and the Peguero-Lo Presti score were assessed. RESULTS The mean left ventricular mass index was 109 ± 34 g/m2 , and 131 (47%) patients had echocardiography LVH. The areas under the receiver operator characteristics curve (AUC) for the Sokolow-Lyon index, the Cornell product, the Romhilt-Estes score, and the Peguero-Lo Presti score for the prediction of echocardiography LVH were 0.59, 0.70, 0.63, and 0.65. The Peguero-Lo Presti score had the numerically greatest AUC for the prediction of left ventricular end-diastolic pressure >15 mmHg, mean pulmonary artery wedge pressure >15 mmHg, pulmonary vascular resistance >3 Wood units, mean right atrial pressure >14 mmHg, and stroke volume index <31 mL/m2 . After a median follow-up of 1365 (interquartile range: 931-1851) days after AVR only the Peguero-Lo Presti score was significantly associated with all-cause mortality [hazard ratio: 1.24 (95% confidence interval: 1.01-1.54); per 1 mV increase; p = .045]. CONCLUSIONS Among severe AS patients, the Peguero-Lo Presti score is associated with abnormalities in cardiac structure including LVH, invasive measures of cardiac damage, and long-term mortality after AVR.

Comprehensive vasodilatation in women with acute heart failure: Novel insights from the GALACTIC randomized controlled trial. Eur J Heart Fail 2023; 25:2218-2229.

Abstract
AIMS Sex-specific differences in acute heart failure (AHF) are both relevant and underappreciated. Therefore, it is crucial to evaluate the risk/benefit ratio and the implementation of novel AHF therapies in women and men separately. METHODS AND RESULTS We performed a pre-defined sex-specific analysis in AHF patients randomized to a strategy of early intensive and sustained vasodilatation versus usual care in an international, multicentre, open-label, blinded endpoint trial. Inclusion criteria were AHF with increased plasma concentrations of natriuretic peptides, systolic blood pressure ≥100 mmHg, and plan for treatment in a general ward. Among 781 eligible patients, 288 (37%) were women. Women were older (median 83 vs. 76 years), had a lower body weight (median 64.5 vs. 77.6 kg) and lower estimated glomerular filtration rate (median 48 vs. 54 ml/min/1.73 m2 ). The primary endpoint, a composite of all-cause mortality or rehospitalization for AHF at 180 days, showed a significant interaction of treatment strategy and sex (p for interaction = 0.03; hazard ratio adjusted for female sex 1.62, 95% confidence interval 1.05-2.50; p = 0.03). The combined endpoint occurred in 53 women (38%) in the intervention group and in 35 (24%) in the usual care group. The implementation of rapid up-titration of renin-angiotensin-aldosterone system (RAAS) inhibitors was less successful in women versus men in the overall cohort and in patients with heart failure with reduced ejection fraction (median discharge % target dose in patients randomized to intervention: 50% in women vs. 75% in men). CONCLUSION Rapid up-titration of RAAS inhibitors was less successfully implemented in women possibly explaining their higher rate of all-cause mortality and rehospitalization for AHF.

Pulmonary Congestion by Conventional Chest Radiography: Relationship With Hemodynamics and Mortality in Patients With Severe Aortic Stenosis. CJC Open 2023; 5:938-946.

Abstract
Background The relationship between chest radiograph (CXR) findings of pulmonary congestion and invasive hemodynamics and clinical outcomes in patients with cardiac diseases is unclear. We assessed the correlation between a CXR-based congestion score (RxCS) and the mean pulmonary artery wedge pressure (mPAWP) and the prognostic impact of RxCS and mPAWP in severe aortic stenosis (AS). Methods In 471 patients with severe AS undergoing right heart catheterization and upright CXR, the RxCS was calculated (6 items, maximum score: 10 points) independently by 2 radiologists (average value taken) blinded to clinical data. Congestion was defined as an RxCS > 1. Four patterns were defined based on the presence or absence of congestion (C+ or C-) and elevated (> 15 mm Hg) or normal mPAWP (P+ or P-). Results The median (interquartile range) RxCS was 1 (0-2). Patients with an RxCS > 1 (n = 207) had a higher mean right atrial pressure, mean pulmonary artery pressure, mPAWP, and pulmonary vascular resistance than patients with an RxCS ≤ 1 (n = 264). However, the correlation between the RxCS and the mPAWP was moderate only (r = 0.45). Patients with a C+/P+ pattern had the worst hemodynamics, whereas C-/P- patients had the most favourable constellation. After a median post-valve replacement follow-up of 1361 days, mortality was higher in patients with RxCs > 1 vs ≤ 1 as well as mPAWP > 15 mm Hg vs ≤15 mm Hg. Mortality was highest in C+/P+ patients and lowest in C-/P- patients, whereas it was intermediate in C-/P+ and C+/P- patients. Conclusions In AS patients, RxCS and mPAWP have a significant but moderate correlation. Both RxCS and mPAWP provide prognostic information.

Abstract
BACKGROUND Nation-wide hospitalization databases include diagnostic information at the level of an entire population over an extended period of time. Comorbidity network and early disease development can be unveiled. Chronic obstructive pulmonary disease (COPD) is an underdiagnosed condition for which it is crucial to identify early disease indicators. The identification of gender-specific conditions preceding the onset of COPD may reveal disease progression patterns allowing for early diagnosis and intervention. The objective of the study was to investigate the antecedent hospitalization history of patients newly diagnosed with COPD and to retrace a gender-specific trajectory of coded entities prior to the onset of COPD. MATERIAL AND METHODS A population-wide hospitalization database including information about all hospitalizations in Switzerland between 2002 and 2018 was used. COPD cases were extracted from the database and comorbidities occurring prior to the onset of COPD identified. Comorbidities significantly over-represented in COPD compared with a 1:1, age- and sex-matched control population were identified and their longitudinal evolution was analyzed. RESULTS Between 2002 and 2018, 697,714 hospitalizations with coded COPD were recorded in Switzerland. Sixty-two diagnoses were significantly over-represented before onset of COPD. These preceding comorbidities included both well-established conditions and novel links to COPD. Early pre-conditions included nicotine and alcohol abuse, obesity and cardiovascular diseases. Later comorbidities included atrial fibrillation, diseases of the genitourinary system and pneumonia. Atherosclerotic heart diseases were more prevalent in males, whereas hypothyroidism, varicose and intestinal disorders were more frequent in females. Disease trajectories were validated using an independent data set. CONCLUSIONS Gender-specific disease trajectories highlight early indicators and pathogenetic links between COPD and antecedent diseases and could allow for early detection and intervention.

Estimated glomerular filtration rate, haemodynamics, and mortality in patients with aortic stenosis. Eur J Clin Invest 2023; 53:e13965.

Abstract
BACKGROUND In aortic stenosis (AS), estimated glomerular filtration rate (eGFR) is an important prognostic marker but its haemodynamic determinants are unknown. We investigated the correlation between eGFR and invasive haemodynamics and long-term mortality in AS patients undergoing aortic valve replacement (AVR). METHODS We studied 503 patients [median (interquartile range) age 76 (69-81) years] with AS [indexed aortic valve area .42 (.33-.49) cm2 /m2 ] undergoing cardiac catheterization prior to surgical (72%) or transcatheter (28%) AVR. Serum creatinine was measured on the day before cardiac catheterization for eGFR calculation (CKD-EPI formula). RESULTS The median eGFR was 67 (53-82) mL/min/1.73 m2 . There were statistically significant correlations between eGFR and mean right atrial pressure (r = -.13; p = .004), mean pulmonary artery pressure (mPAP; r = -.25; p < .001), mean pulmonary artery wedge pressure (r = -.19; p < .001), pulmonary vascular resistance (r = -.21; p < .001), stroke volume index (r = .16; p < .001), extent of coronary artery disease, and mean transvalvular gradient but not indexed aortic valve area. In multivariate linear regression, higher age, lower haemoglobin, lower mean transvalvular gradient (i.e. lower flow), lower diastolic blood pressure, and higher mPAP were independent predictors of lower eGFR. After a median post-AVR follow-up of 1348 (948-1885) days mortality was more than two-fold higher in patients in the first eGFR quartile compared to those in the other three quartiles [hazard ratio 2.18 (95% confidence interval 1.21-3.94); p = .01]. CONCLUSION In patients with AS, low eGFR is a marker of an unfavourable haemodynamic constellation as well as important co-morbidities. This may in part explain the association between low eGFR and increased post-AVR mortality.

Abstract
AIMS Blood pressure (BP) targets in patients with aortic stenosis (AS) are controversial. This study sought to describe the haemodynamic profile and the clinical outcome of severe AS patients with low versus high central meaarterial pressure (MAP). METHODS AND RESULTS Patients with severe AS (n = 477) underwent right and left heart catheterization prior to aortic valve replacement (AVR). The population was divided into MAP quartiles. The mean systolic BP, diastolic BP, and MAP in the entire population were 149 ± 25, 68 ± 11, and 98 ± 14 mmHg. Patients in the lowest MAP quartile had the lowest left ventricular ejection fraction (LVEF), systemic vascular resistance, and valvulo-arterial impedance, whereas there were no significant differences in mean right atrial pressure, mean pulmonary artery wedge pressure, pulmonary vascular resistance, and stroke volume index across MAP quartiles. However, left ventricular stroke work index (LVSWI) was lowest in patients in the lowest and highest in those in the highest MAP quartile. After a median (interquartile range) post-AVR follow-up of 3.7 (2.6-5.2) years, mortality was highest in patients in the lowest MAP quartile [hazard ratio 3.08 (95% confidence interval 1.21-7.83); P = 0.02 for lowest versus highest quartile]. In the multivariate analysis, lower MAP [hazard ratio 0.78 (95% confidence interval 0.62-0.99) per 10 mmHg increase; P = 0.04], higher mean right atrial pressure and lower LVEF were independent predictors of death. CONCLUSIONS In severe AS patients, lower MAP reflects lower systemic vascular resistance and valvulo-arterial impedance, which may help to preserve stroke volume and filling pressures despite reduced left ventricular performance, and lower MAP is a predictor of higher long-term post-AVR mortality.

Abstract
Introduction
Little is known about patients with acute myocardial infarction (AMI) and chronic lung disease (CLD). The aim of our study was to analyze risk factors, treatment, and outcome of AMI patients with CLD over the last 20 years using the nationwide AMIS Plus registry.
Methods
All AMI patients enrolled in the AMIS Plus registry with data on CLD between January 2002 and December 2021 were included. Chronic lung disease was determined according to the definition used in the Charlson Comorbidity Index. Data on baseline characteristics, regular medication, immediate therapy within 24 hours, in-hospital interventions and treatments, in-hospital outcome, complications and discharge medication were analyzed using descriptive statistics and logistic regression.
Results
Among 53,680 AMI patients, 5.8% had a CLD. The CLD group included 26.6% female and 73.4% male patients. Gender distribution was similar in patients with and without CLD. Patients with CLD were significantly older (71.2 vs. 65.8 y; p<0.001), more frequently diagnosed with NSTEMI, had more comorbidities and were less frequently never smokers (17.4% vs. 35.3%; p<0.001) compared to patients without CLD. In addition, CLD patients were less likely to receive aspirin, P2Y12 inhibitors, beta-blockers, ACE inhibitors and statins (all p<0.001), and were also less likely to undergo percutaneous coronary interventions (68.7% vs. 82.5%; p<0.001). Median length of stay was 2 days longer for CLD patients. Patients with CLD had more major adverse cardiac and cerebrovascular events in-hospital (10.3% vs. 5.9%; p<0.001) and higher crude in-hospital mortality (8.3% vs. 4.7%; p<0.001). However, multivariable regression analysis showed that CLD was not an independent predictor for in-hospital mortality (OR 1.19 (95% CI 0.98–1.45), p=0.081).
Conclusion
Patients with CLD were less likely to receive evidence-based medicine and had a worse in-hospital outcome compared to those without CLD. However, after adjustment, CLD was not an independent predictor of in-hospital mortality.

Budget Impact of Intravenous Iron Therapy with Ferric Carboxymaltose in Patients with Chronic Heart Failure with Reduced Ejection Fraction (HFrEF) and Iron Deficiency in Switzerland. PHARMACOECONOMICS - OPEN 2022; 6:735-743.

Abstract
AIMS A budget impact analysis compared treating patients with heart failure (HF) and reduced ejection fraction (HFrEF) and iron deficiency (ID) in Switzerland with intravenous ferric carboxymaltose (FCM) or placebo. METHODS Clinical data from four international randomized trials showed that FCM versus placebo treatment was associated with a reduced hospitalization rate due to HF. The budget impact of this was modelled over 1 year. Hospital treatment costs for HFrEF, FCM drug costs, and estimated patient numbers were based on published data, official tariffs, specially commissioned analyses of SwissDRG data, and clinical and diagnosis-related groups (DRG) coding expert opinion. The original cost year was 2015. Sensitivity analyses were conducted including updated unit costs from 2019/2020. RESULTS FCM treatment was associated with average cost savings of Swiss Francs (SFr) 503 per patient per year from the perspective of the Swiss mandatory health insurance system. Extrapolating across all eligible HFrEF patients with ID in Switzerland, this amounted to estimated savings of SFr 23,336,873. Sensitivity analyses showed these results to be robust in the face of changes to input parameters like treatment costs, different hospital settings, updated unit costs, and including outpatient treatment and patient co-payments in the analysis. CONCLUSIONS The present analysis shows that using FCM to treat HFrEF patients with ID in line with current guideline recommendations resulted not only in medical benefits but also in significant cost savings. The analysis also provides an example of the pitfalls of transferring economic evaluation results, even between countries with similar hospital reimbursement systems.

Abstract
Therapy of Heart Failure with Reduced Ejection Fraction: What's New in the 2021 Guidelines? Abstract. The spectrum of treatment options for patients with heart failure with reduced ejection fraction (HFrEF) has substantially expanded over the last years. The 2021 guidelines of the European Society of Cardiology propose a new treatment algorithm for patients with HFrEF and define the role of the currently available drugs, interventions and devices in this context. The new standard is a basic therapy consisting of four drugs with different mechanisms of action for all patients with HFrEF: an angiotensin-converting enzyme inhibitor, a betablocker, a mineralocorticoid antagonist, and a sodium glucose co-transporter-2 inhibitor. Additional drugs and/or interventions/devices are indicated depending on the response to the four-drug basic therapy (which has to be up-titrated to the maximally tolerated doses) and the clinical phenotype. In the present article, we discuss the available drugs and devices, their role in the proposed HFrEF treatment algorithm and clinically relevant practical aspects.

Abstract
AIMS OF THE STUDY Spontaneous coronary artery dissection (SCAD) is an increasingly diagnosed cause of acute myocardial infarction. However, there is still a limited number of larger cohorts with long-term follow-up. We report on the largest Swiss single-centre cohort to date, with follow-up of up to 22 years. METHODS We prospectively collected SCAD cases from June 1998 until December 2020. A strategy of systematic follow-up angiography was applied. Information on long-term follow-up was collected up to the end of 2020. Major cardiovascular events (MACE) were defined as all-cause death, non-fatal MI, and non-fatal cardiac arrest. RESULTS We identified 105 SCAD patients (mean age 53 ± 11 years, 98 female, 5 peripartum). Presentation was myocardial infarction in all patients. In 102 patients, there was one contiguous dissection. Three patients had two (n = 2) or three (n = 1) non-contiguous dissections. In the majority of patients (n = 97), the primary treatment approach was conservative (dual antiplatelet therapy for 12 months in 90% of patients, statins in 91%). Seven patients were treated with percutaneous coronary intervention (PCI) and one patient underwent bypass surgery. Elective follow-up angiograms were performed in 73 asymptomatic patients after a median follow-up of 6.0 months (interquartile range [IQR] 5.5-6.5). These showed healing of the dissection (n = 65) or a good result after PCI (n = 5) in 70 patients. Three patients had a persistent dissection but conservative treatment was continued. After a median follow-up of 7.5 years (IQR 3.6-12.5) (longest follow-up: 22.5 years) there were 15 MACE. Five MACE occurred within 30 days of the index event: death following catastrophic peripartum left main SCAD (n = 1), out-of-hospital cardiac arrest with successful resuscitation 16 days after SCAD (n = 1), ST-segment elevation myocardial infarction due to occlusion of the dissected artery 10 hours after the index angiogram with subsequent PCI (n = 1), SCAD of a second vessel 8 days after the index SCAD (n = 1), and non-ST-segment elevation myocardial infarction with persistent, multisite SCAD 10 days after the index event (n = 1). There were 10 late MACE, including myocardial infarction and recurrent SCAD (different vessel/lesion) a median of 7.6 years (IQR 3.9-9.6) after the index event in eight patients and death with unclear cause in two patients. CONCLUSION This SCAD series highlights its highly variable clinical course during the acute phase and in the long term. Although most SCAD patients can be treated conservatively with subsequent healing of the dissection and good clinical outcome, there are also patients with dramatic acute presentation or MACE several years after the initial presentation.

Wedge Pressure vs Left Ventricular End-Diastolic Pressure for Pulmonary Hypertension Classification and Prognostication in Severe Aortic Stenosis. CJC Open 2021; 3:1428-1437. [PMID: 34993454 PMCID: PMC8712584 DOI: 10.1016/j.cjco.2021.07.004] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2021] [Accepted: 07/02/2021] [Indexed: 01/23/2023] Open
Abstract
BACKGROUND Differentiation between precapillary and postcapillary pulmonary hypertension (PH) classically relies on mean pulmonary artery wedge pressure (mPAWP). The left ventricular end-diastolic pressure (LVEDP) is proposed as an equivalent alternative. However, mPAWP and LVEDP may differ substantially. We compared the impact of the choice of using the mPAWP vs the LVEDP on PH classification and mortality prediction in patients with severe aortic stenosis (AS) undergoing valve replacement. METHODS In 335 patients with severe AS , both mPAWP and LVEDP were measured. A mean pulmonary artery pressure ≥ 25 mm Hg was used to define PH, and either mPAWP or LVEDP was used to differentiate between precapillary and postcapillary PH (≤ 15 vs > 15 mm Hg). Mortality after a median follow-up of 1484 days after aortic valve replacement was assessed. RESULTS Overall, mPAWP was lower than LVEDP (16 ± 8 mm Hg vs 21 ± 8 mm Hg; P < 0.001). Among 140 patients (42%) with PH, the PAWP-based classification revealed 76 (54% of those with PH) with isolated postcapillary PH, 48 (34%) with combined pre- and postcapillary PH, and 16 (12%) with precapillary PH. When the LVEDP was used, 59 patients (42%) were differently classified. These patients had higher mortality than those who were not differently classified [hazard ratio 2.79 (95% confidence interval, 1.17-6.65); P = 0.02]. Higher mPAWP was associated with increased mortality [hazard ratio 1.07 (95% confidence interval, 1.03-1.11) per 1 mm Hg; P = 0.001], whereas higher LVEDP was not. CONCLUSIONS Use of LVEDP rather than mPAWP results in a divergent PH classification in nearly every second patient with severe AS. These patients have higher mortality after aortic valve replacement. The mPAWP, but not the LVEDP, predicts mortality.

Effect of a strategy of comprehensive vasodilation versus usual care on health-related quality of life among patients with acute heart failure. ESC Heart Fail 2021; 8:4218-4227. [PMID: 34355538 PMCID: PMC8497201 DOI: 10.1002/ehf2.13543] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2021] [Accepted: 07/16/2021] [Indexed: 11/24/2022] Open
Abstract
Aims We aimed to assess the long‐term effect of a strategy of comprehensive vasodilation versus usual care on health‐related quality of life (HRQL) among patients with acute heart failure (AHF). Methods and results Health‐related quality of life was prospectively assessed by the generic 3‐levelled EQ‐5D and the disease‐specific Kansas City Cardiomyopathy Questionnaire (KCCQ) among adult AHF patients enrolled in an international, multicentre, randomised, open‐label blinded‐end‐point trial of a strategy that emphasized early intensive and sustained vasodilation using maximally tolerated doses of established oral and transdermal vasodilators according to systolic blood pressure. Changes in EQ‐5D and KCCQ from admission to 180 day follow‐up were individually compared between the intensive vasodilatation and the usual care group. Among 666 patients eligible for 180 day follow‐up, 284 (43%, median age 79 years, 35% women) and 198 (30%, median age 77 years, 35% women) had completed the EQ‐5D and KCCQ at baseline and follow‐up, respectively. There was a significant improvement in HRQL as quantified by both, EQ‐5D and KCCQ, from hospitalization to 180 day follow‐up, with no significant differences in the change of HRQL between both treatment strategies. For instance, 39 (26%) versus 33 (25%) patients had an improvement by at least one level in at least two categories in the EQ‐5D. Median increase in KCCQ overall summary score (KCCQ‐OSS) was 17.6 (IQR 2.0–42.6) in the intervention group versus 18.5 (IQR 3.9–39.3) in the usual care group (P < 0.001 vs. baseline, P = 0.945 between groups). Conclusions Among patients with AHF, long‐term HRQL quantified by EQ‐5D and KCCQ improved substantially, with overall no significant differences between a strategy of comprehensive vasodilation versus usual care.

Abstract
Pulmonary hypertension (PH) is common in patients with heart failure (HF). The role of PH in patients with HF with reduced (HFrEF) and preserved (HFpEF) left ventricular ejection fraction (LVEF) has been extensively characterized during the last years. In contrast, the pathophysiology of HF with mid-range LVEF (HFmrEF), and in particular the role of PH in this context, are largely unknown. There is a paucity of data in this field, and the prevalence of PH, the underlying mechanisms, and the optimal therapy are not well-defined. Although often studied together there is increasing evidence that despite similarities with both HFrEF and HFpEF, HFmrEF also differs from both entities. The present review provides a summary of the current concepts of the mechanisms and clinical impact of PH in patients with HFmrEF, a proposal for the non-invasive and invasive diagnostic approach required to define the pathophysiology of PH and its management, and a discussion of future directions based on insights from mechanistic studies and randomized trials. We also provide an outlook regarding gaps in evidence, future clinical challenges, and research opportunities.

Impact of the new pulmonary hypertension definition on long-term mortality in patients with severe aortic stenosis undergoing valve replacement. Clin Cardiol 2021; 44:1276-1285.

Abstract
Background The new 2018 pulmonary hypertension (PH) definition includes a lower mean pulmonary artery pressure (mPAP) cut‐off (>20 mmHg rather than ≥25 mmHg) and the compulsory requirement of a pulmonary vascular resistance (PVR) ≥3 Wood units (WU) to define precapillary PH. We assessed the clinical impact of the 2018 compared to the 2015 PH definition in aortic stenosis (AS) patients undergoing aortic valve replacement (AVR). Methods Severe AS patients (n = 487) undergoing pre‐AVR right heart catheterization were classified according to the 2015 and 2018 definitions. Post‐AVR mortality (median follow‐up 44 months) was assessed. Results Based on the 2015 definition, 66 (13%) patients exhibited combined pre and postcapillary PH (CpcPH), 116 (24%) isolated post‐capillary PH (IpcPH), 28 (6%) precapillary PH, and 277 (57%) no PH at all. Overall, 52 (11%) patients were reclassified: 23 no PH into IpcPH; 8 no PH into precapillary PH; 20 precapillary PH into no PH; 1 CpcPH into IpcPH. By the 2015 definition, only CpcPH patients displayed increased mortality, whereas by the 2018 definition, precapillary PH patients also experienced higher mortality than those without PH. Among the PH definition components, PVR ≥3 WU was the strongest predictor of death (hazard ratio > 4). Conclusions In severe AS, a higher number of IpcPH patients are diagnosed by the 2018 definition, even though they have the same prognosis as those without PH. Patients with true precapillary PH are more accurately identified by the 2018 definition that includes a pulmonary vascular disease criterion, that is, PVR ≥3 WU, a strong mortality predictor.

Abstract
A patient with hypertrophic obstructive cardiomyopathy (HOCM) was admitted with acute heart failure. Echocardiography revealed significantly worsened left ventricular outflow tract obstruction and pulmonary hypertension. Cardiac magnetic resonance imaging showed biventricular dysfunction and, as an unexpected finding, a large embolus in the right pulmonary artery. The patient gradually improved with medical therapy including oral anticoagulation. In HOCM patients, pulmonary embolism may trigger heart failure due to impaired left ventricular filling with consecutive outflow tract obstruction provocation.

Abstract
BACKGROUND The role of the electrocardiogram for risk stratification in patients with severe aortic stenosis is not established. We assessed the hemodynamic correlates and the prognostic value of the corrected QT interval (QTc) in patients with severe aortic stenosis undergoing aortic valve replacement. METHODS The QT interval was measured in a 12-lead electrocardiogram in 485 patients (age 74 ± 10 years, 57% male) with severe aortic stenosis (indexed aortic valve area 0.41 ± 0.13 cm2/m2, left ventricular ejection fraction 58 ± 12%) the day prior to cardiac catheterization. Prolonged QTc was defined as QTc >450 ms in men and QTc >470 ms in women. The outcome parameter was all-cause mortality. RESULTS Patients with prolonged QTc (n = 100; 77 men, 23 women) had similar indexed aortic valve area but larger left ventricular and left atrial size, lower left ventricular ejection fraction, more severe mitral regurgitation, lower cardiac index, and higher mean pulmonary artery pressure, mean pulmonary artery wedge pressure, and pulmonary vascular resistance, as compared with patients with normal QTc (n = 385). After a median follow-up of 3.7 years (interquartile range, 2.6-5.2) after surgical (n = 349) or transcatheter (n = 136) aortic valve replacement, patients with prolonged QTc had higher mortality than those with normal QTc (hazard ratio 2.81 [95% confidence interval, 1.51-5.20]; P < .001). Prolonged QTc was an independent predictor of death along with more severe mitral regurgitation and higher pulmonary vascular resistance. CONCLUSIONS In patients with severe aortic stenosis, prolonged QTc is a marker of an advanced disease stage associated with an adverse hemodynamic profile and increased long-term mortality after aortic valve replacement.

Abstract
BACKGROUND Both loop diuretics (LDs) and congestion have been related to worse heart failure (HF) outcome. The relationship between the cause and effect is unknown. The aim of this study was to investigate the interaction between congestion, diuretic use and HF outcome. METHODS Six hundred and twenty-two chronic HF patients from TIME-CHF were studied. Congestion was measured by means of a clinical congestion index (CCI). Loop diuretic dose was considered at baseline and month 6. Treatment intensification was defined as the increase in LD dose over 6 months or loop diuretic and thiazide or thiazide-like diuretic co-administration. The end-points were survival and HF hospitalisation-free survival. RESULTS High-LD dose at baseline and month 6 (≥ 80 mg of furosemide per day) was not identified as an independent predictor of outcome. CCI at baseline remained independently associated with impaired survival [hazard ratio (HR) 1.34, (95% confidence interval) (95% CI) (1.20-1.50), p < 0.001] and HF hospitalisation-free survival [HR 1.09, 95% CI (1.02-1.17), p = 0.015]. CCI at month 6 was independently associated with HF hospitalisation-free survival [HR 1.24, 95% CI (1.11-1.38), p < 0.001]. Treatment intensification was independently associated with survival [HR 1.75, 95% CI (1.19-1.38), p = 0.004] and HF hospitalisation-free survival [HR 1.69, 95% CI (1.22-2.35), p = 0.002]. Patients undergoing treatment intensification resulting in decongestion had better outcome than patients with persistent (worsening) congestion despite LD dose up-titration (p < 0.001). CONCLUSION Intensification of pharmacological decongestion but not the actual LD dose was related to poor outcome in chronic HF. If treatment intensification translated into clinical decongestion, outcome was better than in case of persistent or worsening congestion.

Impact of a volume challenge on haemodynamics and prognosis in patients with severe aortic stenosis. ESC Heart Fail 2020; 8:508-517.

Abstract
Aims A volume challenge can unmask pulmonary hypertension (PH) and its mechanism. We evaluated the impact of a volume challenge on mean pulmonary artery pressure (mPAP) and mean pulmonary artery wedge pressure (mPAWP) and its prognostic implications in patients with severe aortic stenosis (AS) undergoing aortic valve replacement (AVR). Methods and results In 285 patients with severe AS (indexed aortic valve area 0.41 ± 0.13 cm2/m2), mPAP and mPAWP were measured before and after administration of 150 ± 58 mL of low‐osmolal or iso‐osmolal contrast. Following contrast, mPAP and mPAWP rose from 25 ± 10 and 16 ± 8 mmHg by 5 ± 4 and 4 ± 4 mmHg to 30 ± 11 and 20 ± 8 mmHg. There were 112 (39%) patients with pre‐contrast PH and 70 (40% of those without pre‐contrast PH) patients with post‐contrast PH only. Post‐contrast PH patients were intermediate between pre‐contrast PH and no PH in terms of AS severity, cardiac dysfunction, and haemodynamics. After a median follow‐up of 43 months post‐AVR, pre‐contrast PH patients had numerically the highest mortality driven by those with pre‐contrast combined pre‐capillary and post‐capillary PH (n = 35), while post‐contrast changes in mPAP and mPAWP were not related to mortality. Patients with any post‐contrast mPAWP > 18 mmHg had significantly higher mortality than those with post‐contrast mPAWP ≤ 18 mmHg, Conclusions In severe AS, a contrast challenge leads to post‐contrast PH in ~40% of patients without pre‐contrast PH. However, post‐contrast haemodynamic changes do not adversely affect outcomes in patients undergoing AVR. Post‐contrast PH represents an intermediate stage of ‘cardiac damage’, which may be attenuated or reversible after AVR.

Abstract
BACKGROUND β-Blockers (BBs) are mainstay therapy for heart failure with reduced ejection fraction. However, individual patient responses to BB vary, which may be partially due to genetic variation. The goal of this study was to derive and validate the first polygenic response predictor (PRP) for BB survival benefit in heart failure with reduced ejection fraction patients. METHODS Derivation and validation analyses were performed in n=1436 total HF patients of European descent and with ejection fraction <50%. The PRP was derived in a random subset of the Henry Ford Heart Failure Pharmacogenomic Registry (n=248) and then validated in a meta-analysis of the remaining patients from Henry Ford Heart Failure Pharmacogenomic Registry (n=247), the TIME-CHF (Trial of Intensified Versus Standard Medical Therapy in Elderly Patients With Congestive Heart Failure; n=431), and HF-ACTION trial (Heart Failure: a Controlled Trial Investigating Outcomes of Exercise Training; n=510). The PRP was constructed from a genome-wide analysis of BB×genotype interaction predicting time to all-cause mortality, adjusted for Meta-Analysis Global Group in Chronic Heart Failure score, genotype, level of BB exposure, and BB propensity score. RESULTS Five-fold cross-validation summaries out to 1000 single-nucleotide polymorphisms identified optimal prediction with a 44 single-nucleotide polymorphism score and cutoff at the 30th percentile. In validation testing (n=1188), greater BB exposure was associated with reduced all-cause mortality in patients with low PRP score (n=251; hazard ratio, 0.19 [95% CI, 0.04-0.51]; P=0.0075) but not high PRP score (n=937; hazard ratio, 0.84 [95% CI, 0.53-1.3]; P=0.448)-a difference that was statistically significant (P interaction, 0.0235). Results were consistent regardless of atrial fibrillation, ejection fraction (≤40% versus 41%-50%), or when examining cardiovascular death. CONCLUSIONS Among patients of European ancestry with heart failure with reduced ejection fraction, a PRP distinguished patients who derived substantial survival benefit from BB exposure from a larger group that did not. Additional work is needed to prospectively test clinical utility and to develop PRPs for other population groups and other medications.

Hemodynamic profile of patients with severe aortic valve stenosis and atrial fibrillation versus sinus rhythm. Int J Cardiol 2020; 311:39-45. [PMID: 32276775 DOI: 10.1016/j.ijcard.2020.03.084] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/30/2019] [Revised: 02/14/2020] [Accepted: 03/30/2020] [Indexed: 01/09/2023]
Abstract
BACKGROUND In patients with severe aortic stenosis (AS), atrial fibrillation (AF) is associated with increased long-term mortality after aortic valve replacement (AVR), which may be due to unfavorable hemodynamics in AF. We aimed to analyze the hemodynamic profile of patients with severe AS and AF versus sinus rhythm (SR). METHODS We performed cardiac catheterization in 486 patients (age 74 ± 10 years, 58% males) with severe AS [indexed aortic valve area 0.41 ± 0.13 cm2, left ventricular ejection fraction 58 ± 12%]: 50 patients had AF, and 436 patients had SR. All patients underwent surgical (n = 350) or transcatheter (n = 136) AVR. RESULTS Despite similar indexed aortic valve area (0.41 ± 0.11 vs. 0.41 ± 0.12 cm2/m2; p = 0.45) patients with AF had lower left ventricular ejection fraction, larger left atrial size, lower tricuspid annular plane systolic excursion, higher mean pulmonary artery pressure (34 ± 13 vs. 24 ± 9 mmHg), mean pulmonary artery wedge pressure (mPAWP; 22 ± 8 vs. 15 ± 7 mmHg), and pulmonary vascular resistance (2.8 ± 1.9 vs. 2.0 ± 1.3 Wood units) and lower stroke volume index (26 ± 9 vs. 37 ± 10 ml/m2) than patients with SR (p < 0.05 for all). Patients with AF and SR had a different mPAWP-left ventricular end-diastolic pressure (LVEDP) relationship with higher mPAWP in AF and higher LVEDP in SR. After a median follow-up of 49 (interquartile range, 35-64) months post-AVR patients with AF (p = 0.05) and patients with a larger difference between mPAWP and LVEDP (p = 0.005) had higher mortality. CONCLUSIONS Patients with severe AS and concomitant AF have a distinct and significantly worse hemodynamic profile compared to patients with SR associated with worse clinical outcome.

Limited role for fibroblast growth factor 23 in assessing prognosis in heart failure patients: data from the TIME-CHF trial. Eur J Heart Fail 2020; 22:701-709. [PMID: 32020782 DOI: 10.1002/ejhf.1749] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/14/2019] [Revised: 11/30/2019] [Accepted: 12/27/2019] [Indexed: 12/16/2022] Open
Abstract
AIM Fibroblast growth factor 23 (FGF23) is an intensively studied biomarker at the crossroads of cardiovascular disease, heart failure (HF) and chronic kidney disease. Independent associations between increasing FGF23 levels and cardiovascular events were found in many, but not all studies. By analysing data from the TIME-CHF cohort, we sought to investigate the prognostic value of FGF23 in an elderly, multimorbid HF patient cohort. We determined differences between intact (iFGF23) and C-terminal FGF23 (cFGF23) regarding their prognostic value and their levels over time in different HF subgroups according to left ventricular ejection fraction (LVEF). METHODS AND RESULTS In this multicentre trial of 622 patients with symptomatic HF aged ≥60 years, we determined iFGF23 and cFGF23 at baseline, 3, 6 and 12-month follow-up. In unadjusted analyses, cFGF23 significantly predicted all HF-related outcomes at all time points. The predictive value of iFGF23 was less and not statistically significant at baseline. After multivariable adjustments, the association between both cFGF23 and iFGF23 and outcome lost statistical significance apart from cFGF23 at month 3. Overall, patients with preserved and mid-range LVEF had higher levels of iFGF23 and cFGF23 than those with reduced LVEF. Levels decreased significantly during the first 3 months in mid-range and reduced LVEF patients, but did not significantly change over time in those with preserved LVEF. CONCLUSIONS Fibroblast growth factor 23 is of limited value regarding risk prediction in this elderly HF population. Potentially heterogeneous roles of FGF23 in different LVEF groups deserve further investigation.

Relationship between B-type natriuretic peptide and invasive haemodynamics in patients with severe aortic valve stenosis. ESC Heart Fail 2020; 7:577-587. [PMID: 31994357 PMCID: PMC7160488 DOI: 10.1002/ehf2.12614] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2019] [Revised: 11/22/2019] [Accepted: 12/23/2019] [Indexed: 11/08/2022] Open
Abstract
AIMS In patients with aortic stenosis (AS), B-type natriuretic peptide (BNP) is a prognostic marker. However, there is little information on the association between BNP and invasive haemodynamics in AS. The aim of the present study was to assess the hitherto not well-defined relationship between BNP and invasive haemodynamics in patients with severe AS undergoing aortic valve replacement (AVR) with a view to understand the link between high BNP and poor prognosis in these patients. In particular, we were interested in the association between BNP and combined pre-capillary and post-capillary pulmonary hypertension (CpcPH). METHODS AND RESULTS BNP was measured in 252 patients (age 74 ± 10 years, 58% male patients) with severe AS [indexed aortic valve area 0.4 ± 0.1 cm2 /m2 and left ventricular ejection fraction (LVEF) 57 ± 12%] the day before cardiac catheterization. Patients were followed for a median (interquartile range) period of 3.1 (2.3-4.3) years after surgical (n = 157) or transcatheter (n = 95) AVR. The prevalence of CpcPH (mean pulmonary artery pressure ≥ 25 mmHg, mean pulmonary artery wedge pressure > 15 mmHg, and pulmonary vascular resistance > 3 Wood units) was 13%. The median BNP plasma concentration was 188 (78-452) ng/L. The indexed aortic valve area was similar across BNP quartiles (P = 0.21). Independent predictors of higher BNP (ln transformed) included lower haemoglobin (beta = -0.18; P < 0.001), lower LVEF (beta = -0.20; P < 0.001), more severe mitral regurgitation (beta = 0.20; P < 0.001), higher mean pulmonary artery wedge pressure (beta = -0.37; P < 0.001), and higher pulmonary vascular resistance (beta = 0.21; P < 0.001). In a multivariate model with CpcPH rather than its haemodynamic components, CpcPH was independently associated with higher BNP (0.21; P < 0.001). Higher ln BNP was associated with higher mortality [hazard ratio 1.90 (95% confidence interval 1.33-2.71); P < 0.001] in the univariate analysis. Patients in the third and fourth BNP quartiles had a more than six-fold risk of death compared with patients in the first and second quartiles [hazard ratio 6.29 (95% confidence interval 1.86-21.27); P = 0.003]. In the multivariate analysis, lower LVEF [hazard ratio 0.96 (95% confidence interval 0.94-0.99) per 1% increase; P = 0.01] and CpcPH [hazard ratio 4.58 (95% confidence interval 1.89-11.09); P = 0.001] but not BNP were independently associated with mortality. The areas under the receiver operator characteristics curve for BNP for the prediction of CpcPH and mortality were 0.88 and 0.74, respectively. CONCLUSIONS In patients with severe AS, higher BNP is a marker of the presence of CpcPH and its contributors. The association between BNP and such an adverse haemodynamic profile at least in part explains the ability of BNP to predict long-term post-AVR mortality.

Abstract
IMPORTANCE Short-term infusions of single vasodilators, usually given in a fixed dose, have not improved outcomes in patients with acute heart failure (AHF). OBJECTIVE To evaluate the effect of a strategy that emphasized early intensive and sustained vasodilation using individualized up-titrated doses of established vasodilators in patients with AHF. DESIGN, SETTING, AND PARTICIPANTS Randomized, open-label blinded-end-point trial enrolling 788 patients hospitalized for AHF with dyspnea, increased plasma concentrations of natriuretic peptides, systolic blood pressure of at least 100 mm Hg, and plan for treatment in a general ward in 10 tertiary and secondary hospitals in Switzerland, Bulgaria, Germany, Brazil, and Spain. Enrollment began in December 2007 and follow-up was completed in February 2019. INTERVENTIONS Patients were randomized 1:1 to a strategy of early intensive and sustained vasodilation throughout the hospitalization (n = 386) or usual care (n = 402). Early intensive and sustained vasodilation was a comprehensive pragmatic approach of maximal and sustained vasodilation combining individualized doses of sublingual and transdermal nitrates, low-dose oral hydralazine for 48 hours, and rapid up-titration of angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, or sacubitril-valsartan. MAIN OUTCOMES AND MEASURES The primary end point was a composite of all-cause mortality or rehospitalization for AHF at 180 days. RESULTS Among 788 patients randomized, 781 (99.1%; median age, 78 years; 36.9% women) completed the trial and were eligible for primary end point analysis. Follow-up at 180 days was completed for 779 patients (99.7%). The primary end point, a composite of all-cause mortality or rehospitalization for AHF at 180 days, occurred in 117 patients (30.6%) in the intervention group (including 55 deaths [14.4%]) and in 111 patients (27.8%) in the usual care group (including 61 deaths [15.3%]) (absolute difference for the primary end point, 2.8% [95% CI, -3.7% to 9.3%]; adjusted hazard ratio, 1.07 [95% CI, 0.83-1.39]; P = .59). The most common clinically significant adverse events with early intensive and sustained vasodilation vs usual care were hypokalemia (23% vs 25%), worsening renal function (21% vs 20%), headache (26% vs 10%), dizziness (15% vs 10%), and hypotension (8% vs 2%). CONCLUSIONS AND RELEVANCE Among patients with AHF, a strategy of early intensive and sustained vasodilation, compared with usual care, did not significantly improve a composite outcome of all-cause mortality and AHF rehospitalization at 180 days. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT00512759.

Microbiota-derived peptide mimics drive lethal inflammatory cardiomyopathy. Science 2019; 366:881-886.

Abstract
Myocarditis can develop into inflammatory cardiomyopathy through chronic stimulation of myosin heavy chain 6–specific T helper (TH)1 and TH17 cells. However, mechanisms governing the cardiotoxicity programming of heart-specific T cells have remained elusive. Using a mouse model of spontaneous autoimmune myocarditis, we show that progression of myocarditis to lethal heart disease depends on cardiac myosin–specific TH17 cells imprinted in the intestine by a commensalBacteroidesspecies peptide mimic. Both the successful prevention of lethal disease in mice by antibiotic therapy and the significantly elevatedBacteroides-specific CD4+T cell and B cell responses observed in human myocarditis patients suggest that mimic peptides from commensal bacteria can promote inflammatory cardiomyopathy in genetically susceptible individuals. The ability to restrain cardiotoxic T cells through manipulation of the microbiome thereby transforms inflammatory cardiomyopathy into a targetable disease.

Non-invasive assessment prior to invasive coronary angiography in routine clinical practice in Switzerland - Is it according to the guidelines? PLoS One 2019; 14:e0222137. [PMID: 31491029 PMCID: PMC6731015 DOI: 10.1371/journal.pone.0222137] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2019] [Accepted: 08/12/2019] [Indexed: 11/27/2022] Open
Abstract
Background Non-invasive testing is recommended as a basis to decide about the indication for invasive coronary angiography (ICA) in patients with suspected stenotic coronary artery disease (CAD). However, a recent study based on insurance claims data reported that one third of patients undergoing ICA in Switzerland did not have non-invasive testing beforehand. We aimed to re-evaluate the practice of testing prior to ICA in Switzerland by manual review of patient histories. Methods Retrospective analysis of all 816 consecutive patients (age 67±9 years, 70% males) undergoing elective ICA solely for the evaluation of stenotic CAD during the year 2015 in a single center in Eastern Switzerland. The proportion of patients undergoing a non-invasive test was assessed, and predictors of the lack of such a test were determined. Results 764/816 (94%) patients had a non-invasive test prior to ICA. The majority of patients (728/816; 89%) had an exercise stress test, one fifth (160/816; 20%) underwent a test other than an exercise stress test (6% scintigraphy, 4% stress echocardiography, 6% stress magnetic resonance imaging, 4% computed tomography coronary angiography), and 122/816 (15%) patients had two tests. The use of antianginal drugs other than beta-blockers [odds ratio 1.92 (95% confidence interval 1.01–3.66); p = 0.047] and a lower left ventricular ejection fraction [odds ratio 0.97 (95% confidence interval 0.94–0.99) per one % point increase; p = 0.005] were independent predictors of the lack of a non-invasive test. ICA revealed stenotic CAD in 72% of patients, and 54% of patients underwent revascularization. Patients with and without non-invasive tests did not differ with respect to ICA findings and management. Conclusions The present analysis suggests that patients are appropriately selected for ICA based on clinical judgement and non-invasive testing in Switzerland. There is no evidence for an overuse of ICA.

Prognostic Significance of Longitudinal Clinical Congestion Pattern in Chronic Heart Failure: Insights From TIME-CHF Trial. Am J Med 2019; 132:e679-e692. [PMID: 31051151 DOI: 10.1016/j.amjmed.2019.04.010] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/20/2019] [Revised: 04/06/2019] [Accepted: 04/08/2019] [Indexed: 11/16/2022]
Abstract
BACKGROUND The relationship between longitudinal clinical congestion pattern and heart failure outcome is uncertain. This study was designed to assess the prevalence of congestion over time and to investigate its impact on outcome in chronic heart failure. METHODS A total of 588 patients with chronic heart failure older than 60 years of age with New York Heart Association (NYHA) functional class ≥II from the TIME-CHF study were included. The endpoints for this study were survival and hospitalization-free heart failure survival. Orthopnea, NYHA ≥III, paroxysmal nocturnal dyspnea, hepatomegaly, peripheral pitting edema, jugular venous distension, and rales were repeatedly investigated and related to outcomes. These congestion-related signs and symptoms were used to design a 7-item Clinical Congestion Index. RESULTS Sixty-one percent of patients had a Clinical Congestion Index ≥3 at baseline, which decreased to 18% at month 18. During the median [interquartile range] follow-up of 27.2 [14.3-39.8] months, 17%, 27%, and 47% of patients with baseline Clinical Congestion Index of 0, 1-2, and ≥3 at inclusion, respectively, died (P <.001). Clinical Congestion Index was identified as an independent predictor of mortality at all visits (P <.05) except month 6 and reduced hospitalization-free heart failure survival (P <.05). Successful decongestion was related to better outcome as compared to persistent congestion or partial decongestion (log-rank P <0.001). CONCLUSIONS The extent of congestion as assessed by means of clinical signs and symptoms decreased over time with intensified treatment, but it remained present or relapsed in a substantial number of patients with heart failure and was associated with poor outcome. This highlights the importance of appropriate decongestion in chronic heart failure.

Abstract
AIMS OF THE STUDY Coronary computed tomography angiography (CCTA) is recommended as a first-line option for the exclusion of coronary artery disease in patients with low to intermediate (15–50%) pretest probability. We aimed to study the use of CCTA in clinical practice in a single centre in Switzerland in light of this recommendation. METHODS In 523 consecutive patients (age 56 ± 13 years, 48% females) undergoing CCTA during a period of 2 years, the pretest probability of coronary artery disease was assessed using the revised Diamond-Forrester model (CAD consortium score). In patients who had invasive coronary angiography following CCTA, angiographic findings and the consequences regarding management are reported. RESULTS The majority of patients (n = 316; 60%) had a pretest probability <15%, 188/523 (36%) had a pretest probability between 15 and 50%, and 19/523 (4%) had a pretest probability >50%. The prevalences of coronary artery disease (≥50% lumen diameter reduction) by CCTA in patients with pretest probability <15%, 15–50%, and >50% were 25/316 (8%), 45/188 (24%) and 8/19 (42%), respectively. In 438/523 patients (84%), a CCTA scan showing no coronary artery disease represented the final diagnostic step. In patients undergoing invasive coronary angiography (n = 59, age 58 ± 9 years, 88% with coronary artery disease by CCTA), coronary artery disease was found in 47/59 (80%) patients and 36/59 (61%) patients underwent revascularisation. The prevalences of coronary artery disease by invasive coronary angiography in patients with pretest probability <15%, 15–50%, and >50% were 14/21 (67%), 28/32 (88%) and 5/6 (83%). CONCLUSIONS The present data suggest that the currently used pretest probability model is still imperfect and that guideline recommendations regarding pretest probability use for the selection of CCTA candidates are not followed completely. Still, in more than 80% of patients coronary artery disease could be excluded by CCTA, while CCTA also detected a significant number of patients with coronary artery disease in the low pretest probability population. Thus, the data suggest a very judicious use of CCTA as a gatekeeper for invasive coronary angiography in current practice.

Heart failure with preserved ejection fraction (HFpEF) Abstract. Heart failure with preserved left ventricular ejection fraction (HFpEF) is a very common form of heart failure typically seen in older patients and associated with poor prognosis. Patients with HFpEF are characterized by a s small left ventricle with concentric remodeling and abnormal compliance, which under the impact of additional cardiovascular mechanisms and non-cardiac comorbidities, leads to the cardinal symptoms of dyspnea and exercise intolerance. The diagnosis of HFpEF is still under debate, and the therapeutic options are limited despite intensive research efforts. In the present review article, we provide an overview of the current understanding of the pathiohysiology of HFpEF, the current diagnostic approach, and a summary of the available evidence on treatment.

Is the clinical presentation of chronic heart failure different in elderly versus younger patients and those with preserved versus reduced ejection fraction? Eur J Intern Med 2018; 57:61-69.

Abstract
BACKGROUND Whether the clinical presentation and in particular prevalence of symptoms and signs of heart failure (HF) is different in elderly versus younger patients and in those with reduced (HFrEF) versus preserved (HFpEF) left ventricular ejection fraction (LVEF) is a matter of ongoing debate. AIMS To compare detailed clinical characteristics of these important subgroups and to develop a prediction rule for the differentiation of HFpEF and HFrEF based on clinical parameters. METHODS The analysis was based on the Trial of Intensified versus standard Medical therapy in Elderly patients with Congestive Heart Failure (TIME-CHF) comprising 622 patients ≥60 years with HF including the whole LVEF spectrum. RESULTS In the groups ≥75 years and with HFpEF typical symptoms and clinical signs of HF were more prevalent as compared to those <75 years or with HFrEF, respectively. The burden of comorbidities was higher in the older age group. HFrEF could not be differentiated from HFpEF by symptom history and clinical examination alone. However, a combination of age, presence of pulmonary rales, systolic blood pressure, cause of heart failure, osteoporosis, current smoking, NT-proBNP, haemoglobin, QRS width and heart rhythm allowed to identify HFrEF versus HFpEF with a sensitivity of 81% and specificity of 90% (c-statistics 0.91). CONCLUSIONS More symptoms and signs of HF were present both in the older age group and in patients with HFpEF. HFpEF versus HFrEF could be differentiated by a set of simple clinical, laboratory and ECG parameters but not by symptom history and physical examination alone.

Haemodynamic mechanisms and long-term prognostic impact of pulmonary hypertension in patients with severe aortic stenosis undergoing valve replacement. Eur J Heart Fail 2018; 21:172-181.

Abstract
AIMS We aimed to investigate the prevalence, detailed invasive haemodynamics, and prognostic impact of pulmonary hypertension (PH) in severe aortic stenosis (AS). METHODS AND RESULTS We studied 503 patients (mean age 74 ± 10 years) with severe AS (indexed aortic valve area 0.4 ± 0.1 cm2 /m2 , left ventricular ejection fraction 57 ± 12%) undergoing left and right heart catheterization prior to aortic valve replacement. Median follow-up was 3.7 (interquartile range 2.6-5.4) years. Baseline PH (mean pulmonary artery pressure ≥ 25 mmHg) was found in 239 (48%) patients: 31 patients had pre-capillary PH [mean pulmonary artery wedge pressure (mPAWP) ≤ 15 mmHg], 144 had isolated post-capillary PH [IpcPH; mPAWP > 15 mmHg, pulmonary vascular resistance (PVR) ≤ 3 Wood units (WU)], and 64 had combined pre- and post-capillary PH (CpcPH; mPAWP > 15 mmHg, PVR > 3 WU). Patients with CpcPH had higher mortality than those with IpcPH, pre-capillary PH, and without PH. In the multivariate analysis, CpcPH remained an independent predictor of death (hazard ratio 4.39, 95% confidence interval 2.40-8.03; P < 0.001). Patients with CpcPH had higher mPAWP (26 ± 7 vs. 22 ± 5 mmHg) and lower pulmonary arterial capacitance (1.5 ± 0.6 vs. 2.9 ± 1.2 mL/mmHg) than IpcPH patients but similar left ventricular end-diastolic pressure (LVEDP; 25 ± 7 vs. 25 ± 7 mmHg). A smaller LVEDP-mPAWP difference was related to larger left atrial size, atrial fibrillation, and more severe mitral regurgitation. CONCLUSIONS In patients with severe AS, PH is common but underlying mechanisms differ. Patients with CpcPH have higher mPAWP, lower pulmonary arterial capacitance, and worse survival than all other groups. Left atrial dysfunction and mitral regurgitation seem to be drivers of high mPAWP in CpcPH.
