[BLITZ-AF Cancer study: an international observational research project on patients with atrial fibrillation and cancer]

BACKGROUND

Cancer is an important condition associated with the development of atrial fibrillation (AF). The objectives of the BLITZ-AF Cancer study were to collect real-life information on the clinical profile and use of antithrombotic drugs in patients with AF and cancer to improve clinical management, as well as the evaluation of the association between different antithrombotic treatments (or their absence) and the main clinical events.

METHODS

European multinational, multicenter, prospective, non-interventional study conducted in patients with AF (electrocardiographically confirmed) and cancer occurring within 3 years. The CHA2DS2-VASc and the HAS-BLED scores were calculated in all enrolled patients.

RESULTS

From June 2019 to July 2021, 1514 patients were enrolled, 36.5% women, from 112 cardiology departments in 6 European countries (Italy, Belgium, the Netherlands, Spain, Portugal and Ireland). Italy enrolled 971 patients in 77 centers. Average age of patients was 74 ± 9 years, of which 20.9% affected by heart failure, 18.1% by ischemic heart disease, 9.8% by peripheral arterial disease and 38.5% by valvular diseases; 41.5% of patients had a CHA2DS2-VASc score ≥4. The most represented cancer sites were lung (14.9%), colorectal tract (14.1%), prostate (8.8%), or non-Hodgkin's lymphoma (8.1%). Before enrollment, 16.6% of patients were not taking antithrombotic therapy, while 22.7% were on therapy with antiplatelet agents and/or low molecular weight heparin. After enrollment these percentages decreased to 7.7% and 16.6%, respectively and, at the same time, the percentage of patients on direct oral anticoagulant (DOAC) therapy increased from 48.4% to 68.4%, also to the detriment of those on vitamin K antagonist therapy.

CONCLUSIONS

The BLITZ-AF Cancer study, which enrolled patients diagnosed with AF and cancer, highlights that the use of DOACs by cardiologists in this clinical context has increased, even though the guidelines on AF do not give accurate indications about oral anticoagulant therapy in patients with cancer.

Coagulation Tests and Reversal Agents in Patients Treated with Oral Anticoagulants: The Challenging Scenarios of Life-Threatening Bleeding and Unplanned Invasive Procedures

In clinical practice, the number of patients treated with direct oral anticoagulants (DOACs) has consistently increased over the years. Since anticoagulant therapy has been associated with an annual incidence of major bleeding (MB) events of approximately 2% to 3.5%, it is of paramount importance to understand how to manage anticoagulated patients with major or life-threatening bleeding. A considerable number of these patients' conditions necessitate hospitalization, and the administration of reversal agents may be imperative to manage and control bleeding episodes effectively. Importantly, effective strategies for reversing the anticoagulant effects of DOACs have been well recognized. Specifically, idarucizumab has obtained regulatory approval for the reversal of dabigatran, and andexanet alfa has recently been approved for reversing the effects of apixaban or rivaroxaban in patients experiencing life-threatening or uncontrolled bleeding events. Moreover, continuous endeavors are being made to develop supplementary reversal agents. In emergency scenarios where specific reversal agents might not be accessible, non-specific hemostatic agents such as prothrombin complex concentrate can be utilized to neutralize the anticoagulant effects of DOACs. However, it is paramount to emphasize that specific reversal agents, characterized by their efficacy and safety, should be the preferred choice when suitable. Moreover, it is worth noting that adherence to the guidelines for the reversal agents is poor, and there is a notable gap between international recommendations and actual clinical practices in this regard. This narrative review aims to provide physicians with a practical approach to managing specific reversal agents.

How to Manage Beta-Blockade in Older Heart Failure Patients: A Scoping Review

Beta blockers (BBs) play a crucial role in enhancing the quality of life and extending the survival of patients with heart failure and reduced ejection fraction (HFrEF). Initiating the therapy at low doses and gradually titrating the dose upwards is recommended to ensure therapeutic efficacy while mitigating potential adverse effects. Vigilant monitoring for signs of drug intolerance is necessary, with dose adjustments as required. The management of older HF patients requires a case-centered approach, taking into account individual comorbidities, functional status, and frailty. Older adults, however, are often underrepresented in randomized clinical trials, leading to some uncertainty in management strategies as patients with HF in clinical practice are older than those enrolled in trials. The present article performs a scoping review of the past 25 years of published literature on BBs in older HF patients, focusing on age, outcomes, and tolerability. Twelve studies (eight randomized-controlled and four observational) encompassing 26,426 patients were reviewed. The results indicate that BBs represent a viable treatment for older HFrEF patients, offering benefits in symptom management, cardiac function, and overall outcomes. Their role in HF with preserved EF, however, remains uncertain. Further research is warranted to refine treatment strategies and address specific aspects in older adults, including proper dosing, therapeutic adherence, and tolerability.

[Gender discrepancy: time to implement gender-based clinical management]

It is well established that gender strongly influences cardiovascular risk factors, playing a crucial role in cardiovascular prevention, clinical pathways, diagnostic approach and treatment. Beyond the sex, which is a biological factor, gender entails a socio-cultural condition that impacts access and quality of care due to structural and institutional barriers. However, despite its great importance, this issue has not been adequately covered. Indeed sex and gender differences scarcely impact the clinical approach, creating a lot of disparities in care and outcomes of patients. Therefore, it becomes essential to increase the awareness of the importance of sex and gender influences on cardiovascular diseases. Moreover, new strategies for reducing disparities should be developed. Importantly, these differences should be taken into account in guideline recommendations. In this regard, it is crucial to include a greater number of women in clinical trials, since they are currently underrepresented. Furthermore, more women should be involved as member of international boards in order to develop recommendations and guidelines with more attention to this important topic.The aim of this ANMCO position paper is to shed light on gender differences concerning many cardiovascular drugs in order to encourage a more personalized therapeutic approach.

Recent Advances and Future Directions in Syncope Management: A Comprehensive Narrative Review

Syncope is a highly prevalent clinical condition characterized by a rapid, complete, and brief loss of consciousness, followed by full recovery caused by cerebral hypoperfusion. This symptom carries significance, as its potential underlying causes may involve the heart, blood pressure, or brain, leading to a spectrum of consequences, from sudden death to compromised quality of life. Various factors contribute to syncope, and adhering to a precise diagnostic pathway can enhance diagnostic accuracy and treatment effectiveness. A standardized initial assessment, risk stratification, and appropriate test identification facilitate determining the underlying cause in the majority of cases. New technologies, including artificial intelligence and smart devices, may have the potential to reshape syncope management into a proactive, personalized, and data-centric model, ultimately enhancing patient outcomes and quality of life. This review addresses key aspects of syncope management, including pathogenesis, current diagnostic testing options, treatments, and considerations in the geriatric population.

[ANMCO Position paper: Ionizing radiation exposure and radioprotection in the cath-lab]

In the last decades, because of the improvements in the percutaneous treatment of coronary heart disease, valvular heart disease, congenital heart defects, and the increasing number of cardiac resynchronization therapy and cardioverter-defibrillator implantations, the interventional cardiologists' radio-exposure has importantly risen, causing concerns for ionizing radiation-associated diseases such as cancer and neurodegenerative disorders. Consequently, the radiation exposure issue importantly affects operators' safety. However, our knowledge of this field is poor and most operators are unaware to be at risk, especially because of the absence of effective preventive measures. The aim of this ANMCO position paper is to improve the awareness of operators and identify new ways of reducing operator ionizing radiation dose and minimizing the risk.

Cancer survivorship at heart: a multidisciplinary cardio-oncology roadmap for healthcare professionals

In cancer, a patient is considered a survivor from the time of initial diagnosis until the end of life. With improvements in early diagnosis and treatment, the number of cancer survivors (CS) has grown considerably and includes: (1) Patients cured and free from cancer who may be at risk of late-onset cancer therapy-related cardiovascular toxicity (CTR-CVT); (2) Patients with long-term control of not-curable cancers in whom CTR-CVT may need to be addressed. This paper highlights the importance of the cancer care continuum, of a patient-centered approach and of a prevention-oriented policy. The ultimate goal is a personalized care of CS, achievable only through a multidisciplinary-guided survivorship care plan, one that replaces the fragmented management of current healthcare systems. Collaboration between oncologists and cardiologists is the pillar of a framework in which primary care providers and other specialists must be engaged and in which familial, social and environmental factors are also taken into account.

Management of Patients Treated with Direct Oral Anticoagulants in Clinical Practice and Challenging Scenarios

It is well established that direct oral anticoagulants (DOACs) are the cornerstone of anticoagulant strategy in atrial fibrillation (AF) and venous thromboembolism (VTE) and should be preferred over vitamin K antagonists (VKAs) since they are superior or non-inferior to VKAs in reducing thromboembolic risk and are associated with a lower risk of intracranial hemorrhage (IH). In addition, many factors, such as fewer pharmacokinetic interactions and less need for monitoring, contribute to the favor of this therapeutic strategy. Although DOACs represent a more suitable option, several issues should be considered in clinical practice, including drug-drug interactions (DDIs), switching to other antithrombotic therapies, preprocedural and postprocedural periods, and the use in patients with chronic renal and liver failure and in those with cancer. Furthermore, adherence to DOACs appears to remain suboptimal. This narrative review aims to provide a practical guide for DOAC prescription and address challenging scenarios.

[ANMCO Position paper: Choosing Wisely - ANMCO proposals for 2023]

Nowadays, a progressive and exponential increase in the use of invasive and non-invasive instrumental diagnostics and therapeutic services has been shown. Although unnecessary, instrumental examinations are often largely prescribed, replacing clinical evaluation. Their correct use, on the contrary, would address precise epidemiological and clinical contexts. Therefore identifying whether a test or procedure is appropriate or not plays a crucial role in clinical practice. Several documents from scientific societies and expert groups indicate the most appropriate cardiovascular diagnostic and therapeutic procedures. The international Choosing Wisely campaign invited the main scientific societies to identify five techniques or treatments used in their field that are often unnecessary and may potentially damage patients. The Italian Association of Hospital Cardiologists (ANMCO) joined the project identifying the five cardiological practices in our country at greater risk of inappropriateness in 2014. This list has recently been updated. Moreover, possible solutions to this problem have been proposed.

Cardiovascular Effects of Immune Checkpoint Inhibitors: More Than Just Myocarditis

PURPOSE OF REVIEW

Immune checkpoint inhibitors have reshaped the treatment of cancer, but they are characterized by peculiar toxicity consisting of immune-related adverse events that may potentially affect any organ or system. In this review, we summarize data on clinical presentation, diagnosis, pathogenesis, and management of the main immune-related cardiovascular toxicities of immune checkpoint inhibitors.

RECENT FINDINGS

The most relevant immune-related cardiovascular toxicity is myocarditis, but other non-negligible reported events include non-inflammatory heart failure, conduction abnormalities, pericardial disease, and vasculitis. More recently, growing evidence suggests a role for immune checkpoint inhibitors in accelerating atherosclerosis and promoting plaque inflammation, thus leading to myocardial infarction. Immune checkpoint inhibitors are associated with several forms of cardiovascular toxicity; thus, an accurate cardiovascular baseline evaluation and periodical monitoring are required. Furthermore, the optimization of cardiovascular risk factors before, during, and after treatment may contribute to mitigating both short-term and long-term cardiovascular toxicity of these drugs.

The role of the pregnancy heart team in clinical practice

Significant maternal and fetal morbidity and mortality risk has been shown to be associated with cardiovascular disease in pregnancy. Several determinants, such as the increasing number of females with corrected congenital heart disease in reproductive age, a more advanced maternal age associated with cardiovascular risk factors, and a greater prevalence of preexisting comorbidities related to cardiac disorders such as cancer and COVID-19), lead to a higher incidence of cardiac complications in pregnancy in the last few decades. However, adopting a multidisciplinary strategy may influence maternal and neonatal outcomes. This review aims at assessing the role of the Pregnancy Heart Team, which should ensure careful pre-pregnancy counseling, pregnancy monitoring, and delivery planning for both congenital and other cardiac or metabolic disorders, addressing several emerging aspects in the multidisciplinary team-based approach.

104 EFFECTIVENESS OF 2014 ESC HCM RISK-SCD SCORE IN PREDICTION OF APPROPRIATE ICD SHOCK

Background

Since 2014, European Guidelines have recommended using a novel clinical risk prediction model, called the HCM Risk-SCD, to identify which patients with hypertrophic cardiomyopathy (HCM) who are at higher risk for sudden cardiac death (SCD) and would benefit most from having a prophylactic cardioverter defibrillator (ICD) implantable. In recent years, evidence has called into question the effectiveness of this model in patient selection.

Material and Methods

Data from consecutive patients with HCM and ICD who were followed at our Cardiology Department from January 2000 to January 2022 were retrospectively collected.

Results

Among 702 HCM patients, 52 (7%) received an ICD (female, 31%; mean age at implantation, 49 ± 20; S-ICD, 13%; single-chamber ICD, 50%). Of them, 7 (13%) patients were implanted for secondary prevention while 45 (87%) for primary prevention. Out of the 45 primary prevention patients, 7 (16%) experienced 8 appropriate shocks (AS) while 10 (22%) had 15 inappropriate shocks (IS), during a mean follow up of 8 ± 5 years. Overall, mean HCM Risk-SCD score was 6.8 ± 4.7. Patients with AS showed a non-significant higher risk score when compared to non-AS subjects (7.1 ± 5.4 vs 4.8 ± 5.1, p=0.27). By stratifying study population according to pre-established and clinically adopted HCM Risk-SCD score cut-off (such as < 4 vs. > or = 4), we failed to highlight any significant difference in term of AS between groups. Indeed, out of 10 (22%) patients with HCM Risk-SCD score < 4, 3 (7%) experienced AS, while among 35 (78%) patients with HCM Risk-SCD score > or = 4, 4 (9%) had AS (30% vs. 11%, p=0.17).

Conclusions

The HCM Risk-SCD score does not seem to be able to predict the occurrence of life-threatening ventricular arrhythmias and AS in HCM patients. Our data highlight the need to elaborate a new score in order to improve SCD risk stratification and better select patients for ICD implantation.

102 ICD IMPLANTATION IN PATIENTS WITH HYPERTROPHIC CARDIOMYOPATHY (HCM): A LONG-TERM SINGLE CENTER EXPERIENCE

Background

Subcutaneous ICD (S-ICD) is a safe and effective tool in preventing sudden cardiac death (SCD) and it has the potential to overcome the limitations of transvenous ICDs. Because of increased left ventricular mass and unpredictable electrical substrate, concerns regarding the safety and efficacy of S-ICD in hypertrophic cardiomyopathy (HCM) patients have been raised.

Material and Methods

We retrospectively collected clinical data from consecutive HCM patients who underwent ICD implantation and were followed at our Cardiology Department from January 2000 to January 2022.

Results

Among 702 HCM patients, 52 (7.4%) received an ICD (female, 30.7%; mean age at implantation, 49 ± 20; primary prevention, 86.5%; S-ICD, 13%; single-chamber ICD, 50%). During a mean follow up of 8 ± 5 years, 27 shocks occurred in 20 (38%) patients of which 11 appropriate shocks (AS) in 9 (17%) patients and 16 inappropriate shocks (IS) in 11 (21%) patients, respectively after 4.3 ± 3 and 5 ± 4 years. AS were due to ventricular tachycardia (7) and ventricular fibrillation (4) and occurred in 9 patients with transvenous ICD vs. 0 in S-ICD patients (100% vs. 0%, p=0.32). IS were due to AF (8), PSVT (3), sinus tachycardia (2), and oversensing (3), with a non-significant trend towards a higher rate in patients with transvenous ICD compared to those with S-ICD (33% vs 14%, p=0.41). Device-related complications (DC) were recorded in 14 (27%) patients and were secondary to lead fracture (6), pocket hematoma (3), pneumothorax (1), device malfunctioning (1), endocarditis (2), and venous thrombosis (1). Compared to S-ICD, transvenous ICD was associated with a non-significant higher risk of DC (31% vs. 0%, p=0.17).

Conclusions

In HCM patients at high risk of SCD, when compared to transvenous ICD, S-ICD is related to a non-significant lower rate of IS and DC, with similar rate of AS. Further randomized studies as well as large prospective registries are needed to confirm these findings.

European Society of Cardiology quality indicators for the prevention and management of cancer therapy-related cardiovascular toxicity in cancer treatment

AIMS

To develop quality indicators (QIs) for the evaluation of the prevention and management of cancer therapy-related cardiovascular toxicity.

METHODS AND RESULTS

We followed the European Society of Cardiology (ESC) methodology for QI development which comprises (i) identifying the key domains of care for the prevention and management of cancer therapy-related cardiovascular toxicity in patients on cancer treatment, (ii) performing a systematic review of the literature to develop candidate QIs, and (iii) selecting of the final set of QIs using a modified Delphi process. Work was undertaken in parallel with the writing of the 2022 ESC Guidelines on Cardio-Oncology and in collaboration with the European Haematology Association, the European Society for Therapeutic Radiology and Oncology and the International Cardio-Oncology Society. In total, 5 main and 9 secondary QIs were selected across five domains of care: (i) Structural framework, (ii) Baseline cardiovascular risk assessment, (iii) Cancer therapy related cardiovascular toxicity, (iv) Predictors of outcomes, and (v) Monitoring of cardiovascular complications during cancer therapy.

CONCLUSION

We present the ESC Cardio-Oncology QIs with their development process and provide an overview of the scientific rationale for their selection. These indicators are aimed at quantifying and improving the adherence to guideline-recommended clinical practice and improving patient outcomes.

Cardio-Oncology in Childhood: State of the Art

PURPOSE OF REVIEW

Cardio-oncology is an increasingly important field of cardiology that focuses on the detection, monitoring, and treatment of cardiovascular disease (CVD) occurring during and after oncological treatments. The survival rate for childhood cancer patients has dramatically increased thanks to new treatment protocols and cardiovascular (CV) sequelae represent the third most frequent cause of mortality in surviving patients. This study aims to provide a complete and updated review of all the main aspects of cardio-oncology in childhood and to highlight the critical issues.

RECENT FINDINGS

The problem of CV complications in childhood cancer survivors raises the need to make an early diagnosis of cardiotoxicity by the new imaging and laboratory techniques in order to intervene promptly and to implement pharmacological strategies and lifestyle changes to reduce or even to prevent cardiac injury. Furthermore, a stratification of CV risk, also including new predisposing factors such as the presence of some genetic mutations, is of paramount importance before undertaking oncological treatments. Besides, a systematic and personalized planning of long-term follow-up is fundamental to ensure a transition from pediatric to adult hospital and to avoid missed or late diagnosis of cardiomyopathy. We reviewed the main risk factors for cardiotoxicity in children, both traditional and emerging ones: the mechanisms of toxicity of both old and new antineoplastic therapies, the techniques for detecting cardiac damage, and the current evidence regarding pharmacological cardioprotection. At the end, we focused our attention on the existing guidelines and strategies about the long-term follow-up of childhood cancer survivors.

[Cardio-oncogeriatrics: ANMCO position paper on cardio-oncology management of elderly patients]

Geriatric patients are an increasing population and cancer treatment in this population is a challenging and unsolved issue. Ageing is characterized by low-grade inflammation (inflamm-ageing), an important driver for age-related diseases such as cardiovascular diseases and cancer. These chronic conditions share pathophysiological bases, risk factors and may coexist. The burden of comorbidities lowers the threshold for cardiotoxic effects of oncologic treatments. Geriatric assessment is helpful in identifying the peculiar vulnerabilities of this complex population, but a multidisciplinary approach (with oncologists and cardio-oncologists) is needed to improve the appropriateness of care. In this ANMCO position paper, we define the role of cardio-oncologists in the different scenarios of older cancer patients (active cancer, long-term survivors), the importance of geriatric assessment, the unmet needs of survivors and the complexity of comorbidity management.

Baseline characteristics of patients with atrial fibrillation and cancer enrolled in the BLITZ-AF Cancer registry

Background

Evidences on atrial fibrillation (AF) in patients with cancer are limited, specifically with respect to antithrombotic therapy.

Methods

BLITZ-AF Cancer is a prospective, non-interventional study of the epidemiology and management of AF in patients with cancer. Patients were included from 112 cardiology units in Italy, Belgium, Netherlands, Spain, Portugal, and Ireland, based on the following criteria: age ≥18 years; documented cancer other than basal-cell or squamous-cell carcinoma of the skin diagnosed within 3 years; electrocardiographically confirmed AF within 1 year; no concomitant interventional study. Follow-up is ongoing.

Results

From June 26th, 2019 to Sep. 30th, 2021, 1,514 subjects were enrolled.

The most frequent cancer locations were lung (14.9%), colorectal (14.1%), breast (13.9%), prostate (8.8%), and non-Hodgkin lymphoma (8.1%); 463 (30.6%) of participants had metastases.

AF was first-detected in 323 (21.3%), paroxysmal in 460 (30.4%), persistent in 192 (12.7%), long-standing persistent in 33 (2.2%), and permanent in 506 (33.4%); 590 (39.0%) patients had symptoms attributable to AF.

Baseline characteristics are presented in Table 1. Males were more than women and almost half of the subjects was >75 years-old. Cardiovascular risk factors were common and approximately 31% had heart failure or coronary artery disease. Previous thromboembolic and haemorrhagic events had occurred in 14% and 10% of subjects, respectively. The median CHA2DS2VASc score was 3.

As shown in Figure 1, the prescription of oral anticoagulants, especially direct-acting ones (DOACs), rose after the cardiology assessment, while the percentage of participants without any antithrombotic therapy declined.

Among 1,427 patients with non-valvular AF (i.e., no mitral stenosis or prosthetic mechanical valve), 997 (69.9%) were prescribed on DOACs at discharge/after consultation. At multivariable logistic regression analysis, variables associated with DOAC use were female sex (OR 1.58, 95% CI 1.22–2.05), age (OR 2.00, 95% CI 1.39–2.88 and OR 2.63, 95% CI 1.84–3.76, respectively, for 65–74 years and ≥75 years vs <65 years), hypertension (OR 1.43, 95% CI 1.10–1.87), long-standing persistent or permanent AF (OR 1.36, 95% CI 1.05–1.78). Haemoglobin <12 g/dL (OR 0.57, 95% CI 0.45–0.73), and planned cancer treatment (OR 0.72, 95% CI 0.57–0.92) were independently associated with a lower prescription of DOACs.

Conclusions

BLITZ-AF Cancer provides extensive information on a large, contemporary cohort of individuals with AF and cancer. This baseline snapshot indicates that cardiologists pursue the implementation of DOACs in these patients, although residual use of other antithrombotic therapies or lack of any thrombo-prophylaxis remains substantial.

[ANMCO Position paper: Cardiovascular disease in women - prevention, diagnosis, treatment and organization of care]

Cardiovascular diseases are still the main cause of death among women despite the improvements in treatment and prognosis achieved in the last 30 years of research. The determinant factors and causes have not been completely identified but the role of "gender" is now recognized. It is well known that women tend to develop cardiovascular disease at an older age than men, and have a high probability of manifesting atypical symptoms not often recognized. Other factors may also co-exist in women, which may favor the onset of specific cardiac diseases such as those with a sex-specific etiology (differential effects of estrogens, pregnancy pathologies, etc.) and those with a different gender expression of specific and prevalent risk factors, inflammatory and autoimmune diseases and cancer. Whether the gender differences observed in cardiovascular outcomes are influenced by real biological differences remains a matter of debate.This ANMCO position paper aims at providing the state of the research on this topic, with particular attention to the diagnostic aspects and to care organization.

Superiority of Direct Oral Anticoagulants over Vitamin K Antagonists in Oncological Patients with Atrial Fibrillation: Analysis of Efficacy and Safety Outcomes

Background and aim. Cancer and atrial fibrillation (AF) may be associated, and anticoagulation, either with vitamin K antagonists (VKAs) or direct oral anticoagulants (DOACs), is necessary to prevent thromboembolic events by reducing the risk of bleeding. The log incidence rate ratio (IRR) and 95% confidence interval were used as index statistics. Higgin’s I2 test was adopted to assess statistical inconsistencies by considering interstudy variations, defined by values ranging from 0 to 100%. I2 values of less than 40% are associated with very low heterogeneity among the studies; values between 40% and 75% indicate moderate heterogeneity, and those greater than 75% suggest severe heterogeneity. The aim of this meta-analysis was to compare the safety and efficacy of VKAs and DOACs in oncologic patients with AF. Methods. A meta-analysis was conducted comparing VKAs to DOACs in terms of thromboembolic events and bleeding. A meta-regression was conducted to investigate the differences in efficacy and safety between four different DOACs. Moreover, a sub-analysis on active-cancer-only patients was conducted. Results. A total of eight papers were included. The log incidence rate ratio (IRR) for thromboembolic events between the two groups was −0.69 (p < 0.005). The meta-regression did not reveal significant differences between the types of DOACs (p > 0.9). The Log IRR was −0.38 (p = 0.008) for ischemic stroke, −0.43 (p = 0.02) for myocardial infarction, −0.39 (p = 0.45) for arterial embolism, and −1.04 (p = 0.003) for venous thromboembolism. The log IRR for bleeding events was −0.43 (p < 0.005), and the meta-regression revealed no statistical difference (p = 0.7). The log IRR of hemorrhagic stroke, major bleeding, and clinically relevant non-major bleeding between the VKA and DOAC groups was −0.51 (p < 0.0001), −0.45 (p = 0.03), and 0.0045 (p = 0.97), respectively. Similar results were found in active-cancer patients for all the endpoints except for clinically-relevant non-major bleedings. Conclusions. DOACs showed better efficacy and safety outcomes than VKAs. No difference was found between types of DOACs.

[Pregnancy and heart disease: the role of the Pregnancy Heart Team]

A significant risk of maternal and fetal morbidity and mortality has been shown to be associated with congenital heart disease or heart disease occurring during pregnancy. Given the increasing number of patients with corrected congenital heart disease who reach fertile age and the more and more common advanced maternal age associated with preexisting or intercurrent comorbidities, a higher incidence of cardiac complications in pregnancy has been reported in the last decades. Improvement in maternal and neonatal outcomes is influenced by a multidisciplinary strategy. The purpose of this review is to assess the role of the Pregnancy Heart Team which should ensure careful pre-pregnancy counseling, pregnancy monitoring, and delivery planning for both congenital heart disease and other cardiac or metabolic disorders.

[The importance of intensive lipid-lowering therapy after acute coronary syndrome: changing the paradigm to improve the achievement of targets]

BACKGROUND

Despite the availability of effective lipid-lowering drugs, only few high-risk patients attain their LDL cholesterol (LDL-C) guideline-recommended risk-based goal because of underprescription of combination therapy. We present an 18-month experience with variation of prescription protocols after publication of the 2019 ESC/EAS guidelines for the management of dyslipidemias.

METHODS

Overall, 621 consecutive patients hospitalized for acute coronary syndrome at Mauriziano Hospital in Turin, Italy, between January 2020 and June 2021 were enrolled. Lipid-lowering therapy recommended at discharge was registered to evaluate how many patients received statin monotherapy, statin plus ezetimibe combination or triple therapy with high-intensity statin plus ezetimibe and proprotein convertase subtilisin/kexin type 9 inhibitor (PCSK9i). At 6-month follow-up, the reduction in LDL-C, adverse events, compliance and cardiovascular recurrences was analyzed.

RESULTS

Of 621 patients enrolled, 7 died during hospitalization. During the entire study period, 33% of patients received statin monotherapy, 50% were discharged on statin-ezetimibe combination, and PCSK9i (evolocumab) was prescribed to 17% of patients. Between April 2020 and June 2021, when new recommendations were introduced into clinical practice, 20% of patients received evolocumab, 56% combination therapy and only 24% were discharged on statin monotherapy. At the beginning of observation, evolocumab was prescribed to 3% of patients hospitalized for acute coronary syndrome, while at the end of the study period 27% of patients were discharged on PCSK9i, with an increase of the prescription rate by 759%; in the same period, prescription of statin monotherapy decreased by 75%. At 6-month follow-up, LDL-C reduction was 77% in patients treated with PCSK9i vs 48% in patients taking statin-ezetimibe combination therapy (p<0.001). All patients on evolocumab reached the guideline-directed goals and a low rate of adverse events was reported, mainly represented by local injection site reactions. Six patients experienced acute coronary syndrome recurrence; only one of them was treated with evolocumab.

CONCLUSION

Prescription of intensive lipid-lowering therapy after acute coronary syndrome, eventually with introduction of PCSK9i during hospitalization or at discharge, leads to attainment of guideline-recommended goals for all patients, with a low incidence of adverse events and optimal compliance.

At multivariable logistic regression analysis, variables associated with DOAC use were female sex (OR 1.58, 95% CI 1.22-2.05), age (OR 2.00, 95% CI 1.39-2.88 and OR 2.63, 95%CI 1.84-3.76, respectively, for 65-74 years and ≥75 years vs &lt;65 years), hypertension (OR 1.43, 95%CI 1.10-1.87), long-standing persistent or permanent AF (OR 1.36, 95%CI 1.05-1.78). Haemoglobin &lt;12 g/dL (OR 0.57, 95%CI 0.45-0.73), and planned cancer treatment (OR 0.72, 95%CI 0.57-0.92) were independently associated with a lower prescription of DOACs.

Conclusions

BLITZ-AF Cancer provides extensive information on a large, contemporary cohort of individuals with AF and cancer. This baseline snapshot indicates that cardiologists pursue the implementation of DOACs in these patients, although residual use of other antithrombotic therapies or lack of any thrombo-prophylaxis remains substantial.

C48 PROGNOSTIC IMPACT OF ECHOCARDIOGRAPHIC RESTRICTIVE FILLING PATTERN IN PATIENTS AFFECTED BY HYPERTROPHIC CARDIOMYOPATHY AND PRESERVED SYSTOLIC EJECTION FRACTION

Background

“Restrictive phenotype” is an uncommon presentation of Hypertrophic Cardiomyopathy (HCM), associated with severe functional limitation and poor prognosis. For this reason, current therapeutic aims are prevention of complications through periodic follow–ups and diagnostic investigations, up to the ICD placement.

Objectives

The primary aim of this study was to evaluate the impact of the restrictive filling pattern in HCM on the incidence of complex composite outcome included arrhythmic events, events related to heart failure and general events, correlating it to clinical and imaging data.

Methods

This study is an experimental, multicentric, retrospective and non–randomized analysis, including all patients over the age of 18 suffering from classical HCM, excluding phenocopies and systolic dysfunction. Patients were followed up and selected by specialized Centers of Trieste and Turin and divided by degree of diastolic dysfunction, particularly on the basis of the presence or absence of the restrictive filling pattern.

Results

A total of 367 patients with HCM were included. Restrictive filling pattern was present in 23 patients (6.3%). This subgroup of patients was younger than all other patients (P &lt; 0.001); percentage of ICD patients suffering from severe diastolic dysfunction at follow–up is significantly higher than patients without restrictive filling pattern (39.1% vs 4.1%, P &lt; 0.001). On average, left atrial volume has larger sizes in restrictive filling pattern (109.7ml, SD 43.06 vs 82.8ml, SD 35.81, P = 0.003). Patients with restrictive filling pattern, compared to other patients, are more subjected to heart transplantation (8.7% vs 0.3%, P = 0.009) and hospitalized for heart failure (21.7% vs 7.8%, P = 0.028). Restrictive pattern was not an independent predictor of adverse events at the multivariable analysis. In our cohort, the independent predictors were found to be the left atrium diameter and the presence of LGE on CMR.

Conclusions

In patients with HCM and preserved EF, the evidence of a restrictive diastolic pattern identifies a poor prognosis subgroup. Severe diastolic alteration was not associated with a significant independent role either for events related to heart failure, or for arrhythmic events during a median follow up of 7 years. However, the high rate of ICD implantation in patients with severe diastolic dysfunction suggests a high clinical perception of adverse events in this subgroup.

Management of Acute Coronary Syndrome in Cancer Patients: It's High Time We Dealt with It

Cancer patients have an increased risk of cardiovascular disease and, notably, a significant prevalence of acute coronary syndrome (ACS). It has been shown that an elevated presence of cardiovascular risk factors in this setting leads to an interaction between these two conditions, influencing their therapeutic strategies and contributing to higher mortality. Nonetheless, cancer patients have generally not been evaluated in ACS trials, so that the treatment in these cases is still not fully known. We reviewed the current literature and discussed the best management for these very high-risk patients. The treatment strategy must be tailored based on the cancer type and stage, balancing thrombotic and bleeding risks. When the prognosis is longer than six months, especially if a clinical instability coexists, patients with ACS and cancer should be referred for percutaneous coronary intervention (PCI) as soon as possible. Moreover, an invasive strategy should be preferred in STEMI patients as well as in NSTEMI patients who are considered as high risk. On the contrary, in clinically stable NSTEMI patients, a conservative non-invasive strategy could be adopted, especially in cases of a poor life expectancy and/or of high risk of bleeding. Drug-Eluting-Stents (DES) should be the first choice if an invasive strategy is adopted. Conservative therapy could instead be considered in cancer patients with more stable CAD at an increased risk of major bleeding complications. However, the duration of dual antiplatelet therapy (DAPT) with aspirin and clopidogrel is recommended, but it should be as short as possible, whereas triple antithrombotic therapy is non-advised because it significantly increases the risk of bleeding. ACS management among cancer patients should be based on an accurate evaluation of the risk of thrombosis and bleeding. Future studies focused on choosing optimal strategies in tumor patients with ACS should be performed to treat this subset of patients better.

Breast Cancer and Atrial Fibrillation

This study aims to establish the incidence of atrial fibrillation (AF) in breast cancer (BC) patients, focusing on staging and anti-cancer treatment. A meta-analysis was conducted to investigate the incidence of AF in BC patients and compare this incidence to other cancers. Furthermore, we evaluated the occurrence of AF as an adverse effect of biological therapies vs. non-biological therapies vs. biological therapies + non-biological therapies in BC. Finally, we compared the incidence of AF in early BC and metastatic BC. Thirty studies were included. Twenty-two studies focused on BC, encompassing 166,271 patients. In the BC group, 2.7% of patients developed AF, while in the “all cancer” group, 5.8% of patients developed AF. In addition, there was no difference between different types of therapies (p = 0.61) and between early and metastatic BC (p = 0.57). The type of anti-cancer therapy and the staging of BC does not influence AF’s occurrence in this neoplastic disease.

Obstructive Sleep Apnea and Atrial Fibrillation

Atrial fibrillation (AF) is the most common arrhythmia, increasing with age and comorbidities. Obstructive sleep apnea (OSA) is a chronic sleep disorder more common in older men. It has been shown that OSA is linked to AF. Nonetheless, the prevalence of OSA in patients with AF remains unknown because OSA is significantly underdiagnosed. This review, including 54,271 patients, carried out a meta-analysis to investigate the association between OSA and AF. We also performed a meta-regression to explore cofactors influencing this correlation. A strong link was found between these two disorders. The incidence of AF is 88% higher in patients with OSA. Age and hypertension independently strengthened this association, indicating that OSA treatment could help reduce AF recurrence. Further research is needed to confirm these findings. Atrial Fibrillation (AF) is the most common arrhythmia, increasing with age and comorbidities. Obstructive sleep apnea (OSA) is a regulatory respiratory disorder of partial or complete collapse of the upper airways during sleep leading to recurrent pauses in breathing. OSA is more common in older men. Evidence exists that OSA is linked to AF. Nonetheless, the prevalence of OSA in patients with AF remains unknown because OSA is underdiagnosed. In order to investigate the incidence of AF in OSA patients, we carried out a meta-analysis including 20 scientific studies with a total of 54,271 subjects. AF was present in 4801 patients of whom 2203 (45.9%) had OSA and 2598 (54.1%) did not. Of a total of 21,074 patients with OSA, 2203 (10.5%) had AF and 18,871 (89.5%) did not. The incidence of AF was 88% higher in patients with OSA. We performed a meta-regression to explore interacting factors potentially influencing the occurrence of AF in OSA. Older age and hypertension independently strengthened this association. The clinical significance of our results is that patients with OSA should be referred early to the cardiologist. Further research is needed for the definition of the mechanisms of association between AF and OSA.

Update on Management of Cardiovascular Diseases in Women

Cardiovascular diseases (CVD) have a lower prevalence in women than men; although, a higher mortality rate and a poorer prognosis are more common in women. However, there is a misperception of CVD female risk since women have commonly been considered more protected so that the real threat is vastly underestimated. Consequently, female patients are more likely to be treated less aggressively, and a lower rate of diagnostic and interventional procedures is performed in women than in men. In addition, there are substantial sex differences in CVD, so different strategies are needed. This review aims to evaluate the main gender-specific approaches in CVD.

Cardio-Oncology in the COVID Era (Co & Co): The Never Ending Story

The pathophysiology of some non-communicable diseases (NCDs) such as hypertension, cardiovascular disease (CVD), diabetes, and cancer includes an alteration of the endothelial function. COVID-19 is a pulmonary and vascular disease with a negative impact on patients whose damaged endothelium is particularly vulnerable. The peculiar SARS-CoV-2-induced “endothelitis” triggers an intriguing immune-thrombosis that affects both the venous and arterial vascular beds. An increased liability for infection and an increased likelihood of a worse outcome have been observed during the pandemic in patients with active cancer and in cancer survivors. “Overlapping commonalities” between COVID-19 and Cardio-Oncology have been described that include shared phenotypes of cardiovascular toxicities such as left ventricular dysfunction, ischemic syndromes, conduction disturbances, myocarditis, pericarditis and right ventricular failure; shared pathophysiologic mechanisms such as inflammation, release of cytokines, the renin-angiotensin-aldosterone-pathway, coagulation abnormalities, microthrombosis and endothelial dysfunction. For these features and for the catalyst role of NCDs (mainly CVD and cancer), we should refer to COVID-19 as a “syndemic.” Another challenging issue is the persistence of the symptoms, the so-called “long COVID” whose pathogenesis is still uncertain: it may be due to persistent multi-organ viral attacks or to an abnormal immune response. An intensive vaccination campaign is the most successful pharmacological weapon against SARS-CoV-2, but the increasing number of variants has reduced the efficacy of the vaccines in controlling SARS-CoV-2 infections. After a year of vaccinations we have also learned more about efficacy and side-effects of COVID-19 vaccines. An important byproduct of the COVID-19 pandemic has been the rapid expansion of telemedicine platforms across different care settings; this new modality of monitoring cancer patients may be useful even in a post pandemic era. In this paper we analyze the problems that the cardio-oncologists are facing in a pandemic scenario modified by the extensive vaccination campaign and add actionable recommendations derived from the ongoing studies and from the syndemic nature of the infection.

[ANMCO Position paper: Cardio-oncology in the COVID-19 era]

The COVID-19 pandemic and its impact on patients with cancer and cardiovascular disease have confirmed the particular vulnerability of this population. Indeed, not only a higher risk of contracting the infection has been reported, but also an increased occurrence of a more severe course and unfavorable outcome. Beyond the direct consequences of COVID-19, the pandemic has an enormous impact on global health systems. Screening programs and non-urgent tests have been postponed; clinical trials have suffered a setback. Similarly, in the area of cardiology care, a significant decline in ST-elevation myocardial infarction accesses and an increase in cases of late presenting heart attacks with increased mortality and complication rates have been reported. Health care systems must therefore get ready to tackle the "rebound effect" that will likely show a relative increase in the short and medium term incidence of diseases such as heart failure, myocardial infarction, arrhythmias and cardio- and cerebrovascular complications. Scientific societies are taking action to provide general guidance and recommendations aimed at mitigating the unfavorable outcomes of this pandemic emergency. Cardio-oncology, as an emerging discipline, is more flexible in modulating care pathways and represents a beacon of innovation in the development of multi-specialty patient management. In the era of the COVID-19 pandemic, cardio-oncology has rapidly modified its clinical care pathways and implemented flexible monitoring protocols that include targeted use of cardiac imaging, increased use of biomarkers, and telemedicine systems. The goal of these strategic adjustments is to minimize the risk of infection for providers and patients while maintaining standards of care for the treatment of oncologic and cardiovascular diseases. The aim of this position paper is to evaluate the impact of the COVID-19 pandemic on the management of cardio-oncologic patients with the-state-of-the-art knowledge about SARS-CoV-2 and COVID-19 in order to optimize medical strategies during and after the pandemic.

Portrait of Italian Cardio-Oncology: Results of a Nationwide Associazione Nazionale Medici Cardiologi Ospedalieri (ANMCO) Survey

Aims: Cardio-oncology has achieved a pivotal role in science, but real world data on its clinical impact are still limited.

Methods: A questionnaire was sent out to all cardio-oncology services across Italy (n = 120). The questionnaire was made up of 28 questions divided into four blocks: (A) general information on hospitals and service, (B) the inner organization of cardio-oncology and its relationships with out-of-hospital cardiologists and general practitioners, (C) educational needs and referral guidelines, and (D) activities/specific workload.

Results: Ninety-six out of 120 (80%) completed the questionnaire; 9.4% were cancer centers while 90.6% were general hospitals. A cardio-oncology team was present in 56% of the cancer centers and in 20% only of general hospitals, and a cardio-oncology pathway was active in 55% of cancer centers and in just 14% of the general hospitals. Relationships with out-of-hospital cardiologists and general practitioners were lacking. The guidelines of reference were ESC and ANMCO/AIOM. Patients receiving anthracycline chemotherapy underwent scheduled monitoring by means of echocardiography in 58% of cases. Routine use of cardiac damage biomarkers was overall low, ranging from 22 to 33% while the use of global longitudinal strain reached 44%.

Conclusions: Italian cardio-oncology showed a growing influence on clinical practice but still has room for improvement. Cardio-oncology teams are still scarce, and the application of dedicated paths is poor. The need for specific training has been highlighted.

Unmet Clinical Needs in Elderly Patients Receiving Direct Oral Anticoagulants for Stroke Prevention in Non-valvular Atrial Fibrillation

Vitamin K antagonists have been used for many years as the treatment of choice for long-term oral anticoagulation in patients with non-valvular atrial fibrillation. Unfortunately, the use of those drugs in the real-world setting, particularly among elderly patients, is suboptimal because of their limitations in management. Therefore, many patients were not adequately anticoagulated. Direct oral anticoagulants have been demonstrated to overcome almost all the limitations derived from the use of vitamin K antagonists. Direct oral anticoagulants are at least as effective as vitamin K antagonists in preventing thromboembolic events in patients with non-valvular atrial fibrillation and safer in reducing the risk of intracranial haemorrhage and all-cause mortality. However, as a result of the strict inclusion and exclusion criteria applied to patients, data coming from randomized controlled trials might not apply to the general population. Furthermore, elderly patients were scarcely represented in randomized controlled trials with direct oral anticoagulants. Therefore in elderly patients with non-valvular atrial fibrillation, unmet clinical needs still exist. This review article highlights some of them and provides potential answers based on the results coming from randomized clinical trials, real-world data, and the authors' clinical experience.

Device closure for patent foramen ovale in patients with cryptogenic stroke: which patients should get it?

Patent foramen ovale (PFO) and cryptogenic stroke (CS) both have a high prevalence. The optimal treatment to reduce stroke recurrence after CS remains controversial. Results from clinical trials, meta-analyses, and position papers, support percutaneous PFO device closure and medical therapy compared to medical therapy alone. However, the procedure may be associated with cardiac complications including an increased incidence of new atrial fibrillation. The benefit/risk balance should be determined on a case-by-case basis with the greatest benefit of PFO closure in patients with atrial septal aneurysm and PFO with large shunts. Future studies should address unsolved questions such as the choice of medical therapy in patients not undergoing closure, the duration of antiplatelet therapy, and the role of PFO closure in patients over 60 years old.

Anticoagulation in patients with atrial fibrillation and active cancer: an international survey on patient management

BACKGROUND

In patients with active cancer and atrial fibrillation (AF) anticoagulation, thrombotic and bleeding risk still entail uncertainty.

AIM

We explored the results of an international survey examining the knowledge and behaviours of a large group of physicians.

METHODS AND RESULTS

A web-based survey was completed by 960 physicians (82.4% cardiologists, 75.5% from Europe). Among the currently available anticoagulants for stroke prevention in patients with active cancer, direct oral anticoagulants (DOACs) were preferred by 62.6%, with lower values for low molecular weight heparin (LMWH) (24.1%) and for warfarin (only 7.3%). About 46% of respondents considered that DOACs should be used in all types of cancers except in non-operable gastrointestinal cancers. The lack of controlled studies on bleeding risk (33.5% of respondents) and the risk of drug interactions (31.5%) were perceived as problematic issues associated with use of anticoagulants in cancer. The decision on anticoagulation involved a cardiologist in 27.8% of cases, a cardiologist and an oncologist in 41.1%, and a team approach in 21.6%. The patient also was involved in decision-making, according to ∼60% of the respondents. For risk stratification, use of CHA2DS2-VASc and HAS-BLED scores was considered appropriate, although not specifically validated in cancer patients, by 66.7% and 56.4%, respectively.

CONCLUSION

This survey highlights that management of anticoagulation in patients with AF and active cancer is challenging, with substantial heterogeneity in therapeutic choices. Direct oral anticoagulants seems having an emerging role but still the use of LMWH remains substantial, despite the absence of long-term data on thromboprophylaxis in AF.

Acute coronary syndromes in cancer patients

: Cardiovascular disease and cancer are responsible for the majority of deaths in the Western world. These two entities share common risk factors and their intersection will be more and more frequent in future due to general population aging and long-term cancer control. Clinical presentation, management and outcome of acute coronary syndromes (ACS) in cancer patients could differ from noncancer ones. Cancer patients were frequently excluded from clinical trials and so the paucity of data further complicates the scenario. The management of ACS in cancer patients represents a unique setting in which the risk/benefit ratio of invasive treatment should be carefully evaluated. This review focused on the available evidence of all aspects of ACS in cancer patients providing a guide to a multidisciplinary approach.

[ANMCO/SICI-GISE/SIC/SIECVI/SIRM Consensus document: Appropriateness of multimodality imaging in cardiovascular disease]

The complexity of cardiovascular diseases has led to an extensive use of technological instruments and the development of multimodality imaging. This extensive use of different cardiovascular imaging tests in the same patient has increased costs and waiting times.The concept of appropriateness has changed over time. Appropriateness criteria address the need for specific cardiovascular imaging tests in well-defined clinical scenarios, and define the kind of cardiovascular imaging that is appropriated for each clinical scenario in different stages of the disease. The concept of appropriateness criteria has replaced the old idea of appropriate use criteria and reflects the increasing effort of the international Scientific Societies to create and review in a critical way the management of diagnostic tests used by clinicians.The aim of this Italian consensus document is to address the use of multimodality imaging in the diagnosis and management of the major cardiovascular clinical scenarios, taking into consideration not only the international guidelines and scientific documents already published, but also the reality of Italian laws as well as the various professional profiles involved in patient management and availability of technological diagnostic instruments.

Cardiovascular Risk Factors and Timing of Anthracyclines and Trastuzumab Cardiac Toxicity

BACKGROUND/AIM

Cardiovascular risk factors (CVRFs) predict cardiotoxicity in cancer patients but their role in late cardiac toxicity is less clear.

PATIENTS AND METHODS

This was a retrospective analysis of patients treated with anthracyclines (A) and/or trastuzumab (T) and a correlation with early (≤5 years) or late (>5 years) cardiac toxicity, and baseline CVRFs and CVRFs at toxicity time.

RESULTS

A total of 610 patients were included, 422 with (Group A) and 188 without (Group B) baseline CVRFs. In group A toxicity incidence was 4.7% with all events during treatment or immediately after [mean onset time 0.7 years (range=0.2-1.6)]. Events rate was 3.2% in group B with all events after five years [mean time onset 6.9 years (range=5.2-7.5)]. All group B patients who developed late cardiac toxicity presented with CVRFs at the time of toxicity not reported before.

CONCLUSION

CVRFs could predict late cardiac toxicity and their control should be part of the survivorship program.

[Lifestyle, risk factors and prevention of cancer: role of the cardiologist]

Although commonly thought of as two separate disease entities, cardiovascular diseases and cancer, the leading causes of death, possess various possible interactions, including a number of similar risk factors (e.g. obesity, diabetes, chronic inflammation). Each cardiologist should provide counseling for a correct lifestyle (diet, physical exercise, avoiding smoking and alcohol abuse); doing so, not only cardiovascular diseases, but also cancer could be prevented. Besides, intervention on diet, physical activity and smoking has been shown to be effective even in patients with known cancers. Many drugs used in cardiovascular prevention (i.e. aspirin, metformin, statins, and beta-blockers) have shown in vivo and in vitro promising pleiotropic properties, and, in observational studies, they were also effective in the prevention of some cancers, although this matter is controversial, emphasizing the need for interventional studies in the field of primary and secondary cancer prevention. Considerable interest has emerged regarding the potential adjuvant chemotherapeutic use of these drugs, but real-world epidemiological data remain inconclusive. In this review, we explore the risk factors common to both cardiovascular diseases and cancer, as well as the role of preventive cardiology treatments, highlighting the related major epidemiologic studies and potential biological mechanisms.

Cardio-oncology organization patterns in Italy: one size does not fit all

AIMS

Cardio-oncology is imposing as the specialty deputed to the management of a large and rapidly increasing population of cancer patients receiving anticancer treatments with cardiovascular side effects or presenting with cardiac and oncological comorbidities. Organization patterns dramatically vary across Italy.

METHODS

On the behalf of ANMCO, we have analyzed the characteristics of cardio-oncology services across different hospital types in Italy. A questionnaire was sent out to all ANMCO divisions inquiring about inner organization, workload, multidisciplinary team and inter-hospital connections.

RESULTS

Ninety-eight centers sent back the questionnaire. We summarize different paths into four reference assistance models (sizes XL, L, M and S) according to hospital characteristics, cardio-oncology population size, specialists availability, local facilities and the hospital-surrounding network. We define sizes of the proposed pathways highlighting the need to tailor the model in each single situation.

CONCLUSION

No single cardio-oncology organization model can be applied to all hospitals. Each center could select the size/model that best fits its organization. Multidisciplinarity and networking play a crucial role.

[ANMCO/AICO/AIOM Consensus document: Clinical and management pathways in cardio-oncology]

In Italy, cardiovascular diseases and cancer are the leading causes of death. Both diseases share the same risk factors and, having the highest incidence and prevalence in the elderly, they often coexist in the same individual. Furthermore, the enhanced survival of cancer patients registered in the last decades and linked to early diagnosis and improvement of care, not infrequently exposes them to the appearance of ominous cardiovascular complications due to the deleterious effects of cancer treatment on the heart and circulatory system. The above considerations have led to the development of a new branch of clinical cardiology based on the principles of multidisciplinary collaboration between cardiologists and oncologists: Cardio-oncology, which aims to find solutions to the prevention, monitoring, diagnosis and treatment of heart damage induced by cancer care in order to pursue, in the individual patient, the best possible care for cancer while minimizing the risk of cardiac toxicity. In this consensus document we provide practical recommendations on how to assess, monitor, treat and supervise the candidate or patient treated with potentially cardiotoxic cancer therapy in order to treat cancer and protect the heart at all stages of the oncological disease.

Targeted Cancer Therapies and QT Interval Prolongation: Unveiling the Mechanisms Underlying Arrhythmic Complications and the Need for Risk Stratification Strategies

The care and treatment of cancer patients has significantly changed in the last decade with a remarkable shift towards novel targeted therapies. These promising new drugs may represent effective and potentially life-saving therapeutic options in cancer patients, but are also emerging in the cardiotoxicity scenario for their arrhythmogenic potential due to their QT-prolonging activity. In this article we review the mechanisms underlying drug-induced QT interval prolongation and the classes of anticancer-targeted therapies most frequently responsible for this adverse event, with a particular focus on tyrosine kinase-targeting molecules. Since up to 49 % of serious adverse drug reactions (ADRs) and 58 % of potentially fatal ADRs may not appear on initial drug safety labels, we also review and discuss data from the post-marketing VigiBase^® safety reporting system, the World Health Organization's global database of ADRs. Finally, we discuss arrhythmic risk stratification and prevention strategies in the complex multiple-risk setting of cancer patients, paying particular attention to drug-drug interactions with common antimicrobial, psychotropic and antiemetic supportive care, and we also provide an electrocardiographic QT monitoring algorithm for patients who are candidates for targeted cancer therapies.

Scar Detection by Pulse-Cancellation Echocardiography: Validation by CMR in Patients With Recent STEMI

OBJECTIVES

This study sought to assess an echocardiographic approach (scar imaging echocardiography with ultrasound multipulse scheme [eSCAR]), based on existing multipulse ultrasound scheme, as a marker of myocardial scar in humans, compared with cardiac magnetic resonance assessing late gadolinium enhancement (CMR-LGE).

BACKGROUND

The detection of myocardial scar impacts patient prognosis and management in coronary artery disease and other types of cardiac disease. The clinical experience with echocardiography suggests that the reflected ultrasound signal is often significantly enhanced in infarcted myocardial segments.

METHODS

Twenty patients with a recent ST-segment elevation myocardial infarction (STEMI) (cases) and 15 patients with absent CMR-LGE (negative controls) were imaged with both the eSCAR pulse-cancellation echocardiography and CMR-LGE to assess their potential association.

RESULTS

Scar was detectable at CMR-LGE in 19 of 20 STEMI patients (91%), whereas all (100%) demonstrated eSCAR at echocardiography. In the 19 STEMI patients in whom CMR-LGE was detected, regional matching between eSCAR and CMR-LGE was total, although the segmental extent of detected scar was not always superimposable, particularly in the most apical segments, a region in which eSCAR demonstrated undersensitivity for the true extent of scar.

CONCLUSIONS

A 2-dimensional multipulse echocardiography allows detection of myocardial scar, reliably matching the presence and site of CMR-LGE at 30 days after STEMI, or its absence in negative controls.
