Cardio-Oncology Services: rationale, organization, and implementation

Anthracycline-induced cardiovascular toxicity: validation of the Heart Failure Association and International Cardio-Oncology Society risk score

BACKGROUND AND AIMS

Baseline cardiovascular toxicity risk stratification is critical in cardio-oncology. The Heart Failure Association (HFA) and International Cardio-Oncology Society (ICOS) score aims to assess this risk but lacks real-life validation. This study validates the HFA-ICOS score for anthracycline-induced cardiovascular toxicity.

METHODS

Anthracycline-treated patients in the CARDIOTOX registry (NCT02039622) were stratified by the HFA-ICOS score. The primary endpoint was symptomatic or moderate to severe asymptomatic cancer therapy-related cardiac dysfunction (CTRCD), with all-cause mortality and cardiovascular mortality as secondary endpoints.

RESULTS

The analysis included 1066 patients (mean age 54 ± 14 years; 81.9% women; 24.5% ≥65 years). According to the HFA-ICOS criteria, 571 patients (53.6%) were classified as low risk, 333 (31.2%) as moderate risk, 152 (14.3%) as high risk, and 10 (0.9%) as very high risk. Median follow-up was 54.8 months (interquartile range 24.6-81.8). A total of 197 patients (18.4%) died, and 718 (67.3%) developed CTRCD (symptomatic: n = 45; moderate to severe asymptomatic: n = 24; and mild asymptomatic: n = 649). Incidence rates of symptomatic or moderate to severe symptomatic CTRCD and all-cause mortality significantly increased with HFA-ICOS score [hazard ratio 28.74, 95% confidence interval (CI) 9.33-88.5; P < .001, and hazard ratio 7.43, 95% CI 3.21-17.2; P < .001) for very high-risk patients. The predictive model demonstrated good calibration (Brier score 0.04, 95% CI 0.03-0.05) and discrimination (area under the curve 0.78, 95% CI 0.70-0.82; Uno's C-statistic 0.78, 95% CI 0.71-0.84) for predicting symptomatic or severe/moderate asymptomatic CTRCD at 12 months.

CONCLUSIONS

The HFA-ICOS score effectively categorizes patients by cardiovascular toxicity risk and demonstrates strong predictive ability for high-risk anthracycline-related cardiovascular toxicity and all-cause mortality.

Cancer therapy-related cardiac dysfunction and the role of cardiovascular imaging: systemic review and opinion paper from the Working Group on Cardio-Oncology of the Korean Society of Cardiology

Cardio-oncology is a critical field due to the escalating significance of cardiovascular toxicity as a side effect of anticancer treatments. Cancer therapy-related cardiac dysfunction (CTRCD) is a prevalent condition associated with cardiovascular toxicity, necessitating effective strategies for prediction, monitoring, management, and tracking. This comprehensive review examines the definition and risk stratification of CTRCD, explores monitoring approaches during anticancer therapy, and highlights specific cardiovascular toxicities linked to various cancer treatments. These include anthracyclines, HER2-targeted agents, vascular endothelial growth factor inhibitors, immune checkpoint inhibitors, chimeric antigen receptor T-cell therapies, and tumor-infiltrating lymphocytes therapies. Incorporating the Korean data, this review offers insights into the regional nuances in managing CTRCD. Using systematic follow-up incorporating cardiovascular imaging and biomarkers, a better understanding and management of CTRCD can be achieved, optimizing the cardiovascular health of both cancer patients and survivors.

Complications and comorbidities associated with antineoplastic chemotherapy: Rethinking drug design and delivery for anticancer therapy

Despite the considerable advancements in chemotherapy as a cornerstone modality in cancer treatment, the prevalence of complications and pre-existing diseases is on the rise among cancer patients along with prolonged survival and aging population. The relationships between these disorders and cancer are intricate, bearing significant influence on the survival and quality of life of individuals with cancer and presenting challenges for the prognosis and outcomes of malignancies. Herein, we review the prevailing complications and comorbidities that often accompany chemotherapy and summarize the lessons to learn from inadequate research and management of this scenario, with an emphasis on possible strategies for reducing potential complications and alleviating comorbidities, as well as an overview of current preclinical cancer models and practical advice for establishing bio-faithful preclinical models in such complex context.

Nursing interventions for adult patients undergoing cancer cardiotoxic therapy: Scoping review

PURPOSE

To identify nursing interventions for the management of adult patients undergoing cardiotoxic oncologic therapy.

METHODS

This scoping review was performed in accordance with the JBI guidelines. The literature search took place between July and August 2022. Studies examining interventions for the management of adult cancer patients undergoing cardiotoxic therapy were included. The characteristics and results of the studies were synthesized and analyzed in a narrative way.

FINDINGS

In the nine included studies, it was verified that the interventions were implemented to guide the actions of the health team in general rather than specifically nursing staff. Nine nursing interventions related to the Classification of Nursing Interventions were included.

CONCLUSIONS

The nursing interventions identified focused on rigorous cardiovascular surveillance, risk assessment, and actions to identify and mitigate cardiotoxicity.

IMPLICATIONS FOR NURSING PRACTICE

It is believed that the implementation of the identified nursing interventions will lead to evidence-based nursing practice and will contribute to the development of care products and processes that assess the cardiological risks and cardiotoxicity.

Current use of echocardiography in cardio-oncology: nationwide real-world data from an ANMCO/SIECVI joint survey

Aims

The need for cardio-oncology competencies is constantly growing, and with the establishment of cardio-oncology services, cardiovascular imaging, particularly transthoracic echocardiography (TTE), has become pivotal in patients' management. However, care pathways for oncologic patients largely depend on local health structures' resources. This survey from Associazione Italiana Medici Cardiologi Ospedalieri and the Italian Society of Echocardiography and Cardiovascular Imaging aimed at investigating the use of echocardiography in cardio-oncology services and knowledge levels on cancer patients' care.

Methods and results

Data were obtained via an electronic survey based on a structured questionnaire uploaded to the promoting societies' websites. Responses came from 159 centres with echocardiography. According to one-third of participating centres, workload related to cancer patients represented >30% of the total requests. The most common TTE indication (85%) was left ventricular ejection fraction (LVEF) evaluation. Many centres (55%) still assessed LVEF solely by bidimensional method or visual estimation in case of inadequate acoustic windows. At the same time, almost 40% of centres reported routinely using global longitudinal strain when feasible. We further performed a sub-analysis according to the presence (33%) or absence (77%) of dedicated cardio-oncologists, revealing significant differences in cardiovascular surveillance strategies and cardiotoxicity management.

Conclusion

This survey on echocardiography practice for cancer patients reveals a significant gap between actual clinical practice and standards proposed by recommendations, underlying the need for stronger partnerships between cardiologists and oncologists and dedicated, well-structured cardio-oncology services.

Cardio-oncology and radiation oncology: How collaboration between cardiologists and oncologists can be realised in radiation oncology

Increased survivorship, improvements in cancer treatments, and the potential for cardiac side effects from cancer treatments have resulted in increased collaboration between oncologists and cardiologists and the development of cardio-oncology clinics. This collaboration is important given its role in ensuring greater patient satisfaction, aiding teams of clinicians in making complex treatment decision, and ensuring cardiac complications are diagnosed at an early stage. The particularities of implementing this collaboration in the field of radiation oncology and how this setting is different from other areas of cardio-oncology have not been well detailed in the literature. This paper will discuss what is currently understood about the need for and role of cardio-oncology and what a cardio-oncology services involves, with a particular emphasis on patient and clinician needs in the field of radiation oncology. The literature and recent guidelines do advocate for a detailed baseline assessment of cancer patients undergoing radiotherapy, especially patients with treatment or patient risk factors that increase their risk of cancer-therapy related cardiotoxicity. Advancements in cardiac imaging techniques will be discussed as these may help to diagnose cardiac side effects of certain cancer treatments, including radiotherapy, at an early stage. A multi-disciplinary and collaborative approach is well received by patients and such an approach, guided by the aim of maintaining a patient's cancer treatment wherever possible, should be the cornerstone of cardio-oncology clinics regardless of the patient's treatment regime.

[The Cardio-Oncology Guideline - A Comprehensive Approach to Managing Cardiovascular Risks in Cancer Patients]

The emerging field of cardio-oncology addresses the critical need for specialized cardiovascular care in cancer patients, given the overlapping risk factors and potential cardiovascular complications of oncological therapies. In collaboration with the European Hematology Association (EHA), the European Society for Therapeutic Radiology and Oncology (ESTRO), and the European Society of Cardiology (ESC), the first cardio-oncology guideline was developed and published in 2022. This guideline comprises 272 recommendations covering risk stratification before therapy initiation, monitoring during oncological treatment, and the diagnosis and treatment of therapy-associated cardiovascular side effects.A significant innovation in this guideline is the comprehensive risk stratification approach, which categorizes patients into low, moderate, and high-risk groups based on therapy-specific factors. This allows for tailored cardiovascular care during therapy, with varying frequencies of follow-up examinations depending on the patient's risk level. Notably, the guideline emphasizes the importance of interdisciplinary collaboration between oncologists and cardiologists to optimize patient outcomes.Overall, the cardio-oncology guideline represents a significant advancement in addressing the complex cardiovascular needs of cancer patients. Its comprehensive recommendations and emphasis on interdisciplinary care underscore the importance of optimizing cardiovascular health throughout the oncological treatment journey.This review provides an overview of the guidelines and updates on the risk stratification and therapy of patients with immune checkpoint inhibitor-associated myocarditis (ICIM), as well as the role of statins in protecting against anthracycline-associated cardiotoxicity.

Risk Prediction, Diagnosis and Management of a Breast Cancer Patient with Treatment-Related Cardiovascular Toxicity: An Essential Overview

Breast cancer is amongst the most common invasive cancers in adults. There are established relationships between anti-cancer treatments for breast cancer and cardiovascular side effects. In recent years, novel anti-cancer treatments have been established, as well as the availability of multi-modal cardiac imaging and the sophistication of treatment for cardiac disease. This review provides an in-depth overview regarding the interface of breast cancer and cancer therapy-related cardiovascular toxicity. Specifically, it reviews the pathophysiology of breast cancer, the method of action in therapy-related cardiovascular toxicity from anti-cancer treatment, the use of echocardiography, cardiac CT, MRI, or nuclear medicine as diagnostics, and the current evidence-based treatments available. It is intended to be an all-encompassing review for clinicians caring for patients in this situation.

Higher Mortality in Patients With Diffuse Large B-cell Lymphoma Pre-Existing Arterial Hypertension-Real World Data of the Polish Lymphoma Research Group

BACKGROUND

Arterial hypertension is mentioned as a risk factor in cardio-oncology. This study aimed to assess the long-term prognostic value of arterial hypertension (AH) in diffuse large B-cell lymphoma (DLBCL).

METHODS

We analysed data collected by the Polish Lymphoma Research Group for the evaluation of the outcomes associated with the use of first-line rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone therapy in patients with DLBCL with coexisting AH. Patients with other cardiovascular comorbidities or premature chemotherapy discontinuation due to cardiovascular toxicity were excluded.

RESULTS

Pre-existing AH was diagnosed in 65 of 232 patients with DLBCL (28%) included in the study, and was associated with significantly shorter overall survival values (p<0.00001). The rates of DLBCL recurrence, administration of second-, third-, or fourth-line chemotherapy, and lymphoma-related deaths were similar in patients with and those without AH. Cardiovascular deaths were significantly more frequently observed in patients with pre-existing AH (38.5% vs 3.6%, p<0.0001). In the univariate analysis, AH (p=0.000001), older age (p<0.000001), and diabetes (p=0.0065) were identified as significant predictors of all-cause mortality; however, cardiovascular mortality was associated with AH (p<0.000001), older age (p=0.000008), and dyslipidaemia (p=0.03). Multivariate analysis revealed AH as an age-independent significant predictor of all-cause (p=0.00045) and cardiovascular mortality (p<0.000001).

CONCLUSION

In the long-term follow-up of patients with DLBCL, the role of AH, as an important age-independent predictor of premature cardiovascular mortality, was so strong that it may have value for use in close surveillance in cardio-oncology clinics.

Associations between cardiovascular diseases and cancer mortality: insights from a retrospective cohort analysis of NHANES data

BACKGROUND

This study explored the association of cardiovascular disease (CVD) with cancer mortality risk in individuals with or without a history of cancer, to better understand the interplay between CVD and cancer outcomes.

METHODS

Utilizing data from the National Health and Nutrition Examination Survey (NHANES) spanning 1999 to 2018, a retrospective cohort analysis was conducted. This analysis accounted for the survey's complex design to ensure national representativeness. The association of CVD with cancer mortality was assessed through multivariable Cox proportional hazards models.

RESULTS

The present study included 59,653 participants, of whom 54,095 did not have cancer and 5558 had a history of cancer. In individuals without cancer, heart failure (HF) was associated with an increased risk of mortality from cancer (HR, 1.36; 95% CI, 1.09-1.69; P = 0.005). In participants with cancer, HF correlated with a higher risk of mortality from cancer (HR, 1.76; 95% CI, 1.32-2.34; P < 0.001). Diabetes (DM), hypertension (HBP) and coronary heart disease (CHD) were not significantly associated with an increased risk of mortality from cancer. Significant differences were observed in the interaction between cancer and CHD (HR, 0.68; 95% CI, 0.53-0.87; P = 0.002). For cancer and HBP, a similar trend was noted (HR, 0.75; 95% CI, 0.62-0.91; P = 0.003). No significant differences were found in interactions between HF, DM and cancer.

CONCLUSIONS

HF was associated with an increased risk of mortality from cancer, regardless of cancer history, while HBP, CHD and DM showed no significant association. These findings underscore the importance of understanding the mechanisms behind the increased risk of cancer mortality following HF.

Cardiovascular disease burden in patients with urological cancers: The new discipline of uro-cardio-oncology

Cancer remains a major cause of mortality worldwide, and urological cancers are the most common cancers among men. Several therapeutic agents have been used to treat urological cancer, leading to improved survival for patients. However, this has been accompanied by an increase in the frequency of survivors with cardiovascular complications caused by anticancer medications. Here, we propose the novel discipline of uro-cardio-oncology, an evolving subspecialty focused on the complex interactions between cardiovascular disease and urological cancer. In this comprehensive review, we discuss the various cardiovascular toxicities induced by different classes of antineoplastic agents used to treat urological cancers, including androgen deprivation therapy, vascular endothelial growth factor receptor tyrosine kinase inhibitors, immune checkpoint inhibitors, and chemotherapeutics. In addition, we discuss possible mechanisms underlying the cardiovascular toxicity associated with anticancer therapy and outline strategies for the surveillance, diagnosis, and effective management of cardiovascular complications. Finally, we provide an analysis of future perspectives in this emerging specialty, identifying areas in need of further research.

European Society of Cardiology Core Curriculum for cardio-oncology

Cardio-oncology is a rapidly growing field of cardiovascular (CV) medicine that has resulted from the continuously increasing clinical demand for specialized CV evaluation, prevention and management of patients suffering or surviving from malignant diseases. Dealing with CV disease in patients with cancer requires special knowledge beyond that included in the general core curriculum for cardiology. Therefore, the European Society of Cardiology (ESC) has developed a special core curriculum for cardio-oncology, a consensus document that defines the level of experience and knowledge required for cardiologists in this particular field. It is structured into 8 chapters, including (i) principles of cancer biology and therapy; (ii) forms and definitions of cancer therapy-related cardiovascular toxicity (CTR-CVT); (iii) risk stratification, prevention and monitoring protocols for CTR-CVT; (iv) diagnosis and management of CV disease in patients with cancer; (v) long-term survivorship programmes and cardio-oncology rehabilitation; (vi) multidisciplinary team management of special populations; (vii) organization of cardio-oncology services; (viii) research in cardio-oncology. The core curriculum aims at promoting standardization and harmonization of training and evaluation in cardio-oncology, while it further provides the ground for an ESC certification programme designed to recognize the competencies of certified specialists.

Using the consolidated framework for implementation research (CFIR) to guide implementation of cardio-oncology services

Introduction

Cardio-oncology focuses on diagnosing and preventing adverse cardiovascular outcomes in cancer patients. Interdisciplinary cardio-oncology services address the spectrum of prevention, detection, monitoring, and treatment of cancer patients at risk of cardio-toxicity and aim to improve the continuum of cardiac care for oncology patients. The goal of this study was to engage clinician and administrative stakeholders to assess multilevel needs, barriers, and expectations regarding cardio oncology services.

Methods

We interviewed clinicians and administrators at an academic medical center using the Consolidated Framework for Implementation Research (CFIR) to understand multilevel determinants influencing cardio-oncology service implementation. We also conducted a web-based survey to assess the knowledge, attitude, and perceptions of cardio-oncology services held by local and regional clinicians who may refer cardio-oncology patients to the study site.

Results

Multiple facilitators to cardio-oncology service implementation emerged. Interview participants believed cardio-oncology services could benefit patients and the organization by providing a competitive advantage. A majority (74%) of clinicians surveyed thought a cardio-oncology service would significantly improve cancer patients' prognoses. Implementation barriers discussed included costs and a siloed organizational structure that complicated cross-service collaboration. In the clinician survey, differences in the views toward cardio-oncology services held by cardiology versus oncology providers would need to be negotiated in future cardio-oncology service development. For example, while most providers accepted similar risk of cardio-toxicity when consenting patients for cancer therapy in a curative setting, cardiologists accepted significantly higher levels of risk than oncologists in an incurable setting: 75% of oncologists accepted 1-5% risk; 77% of cardiologists accepted ≥5% risk).

Conclusions

Participants supported implementation and development of cardio-oncology services. Respondents also noted multi-level barriers that could be addressed to maximize the potential for success. Engaging administrators and clinicians from cardiology and oncology disciplines in the future development of such services can help ensure maximal relevance and uptake.

Enhanced supportive care

Enhanced supportive care is a care model providing earlier access to multiprofessional, coordinated care for patients from the point of cancer diagnosis. As a proactive model of care, it stands as a contrast to providing access to a multidisciplinary team once a patient has hit a crisis point, or when their prognosis has become sufficiently poor that they are able to access traditional end-of-life services. Its arrival in the UK through palliative care teams working in cancer care has led to enhanced supportive care being synonymous with early palliative care. While enhanced supportive care has enabled early palliative care, as it has become more embedded in the UK, it has taken on a wider remit for patients living longer with cancer and the management of side effects. Enhanced supportive care services have also begun to provide care for cancer survivors. Enhanced supportive care services have a key role in modern cancer care in maintaining and improving patients' quality of life alongside cancer treatment and ensuring that patients' priorities and preferences for treatment are considered. Furthermore, enhanced supportive care has been shown to support the wider healthcare system by creating capacity within the NHS, reducing demand on hospital services and saving money. As enhanced supportive care services continue to grow and venture into the care and support of cancer survivors and those receiving potentially curative treatments, ongoing work is needed to determine how these services can be made available throughout the NHS and how a shared vision of the way enhanced supportive care operates can be realised.

[Heart and cancer: cardio-oncology]

Cardiovascular diseases and cancer have a complex relationship and show a reciprocal linkage and influence. Mutual risk factors, demographic changes and increasing multimorbidity result in an increase in the incidence of both diseases. Advances in oncological and cardiological treatment lead to a further increase in patients with cured or chronic diseases as a relevant comorbidity. The induction of cardiovascular side effects by cancer therapies leads to increased cardiovascular morbidity and mortality in cancer patients. Recent data also show that cardiovascular disease, through various factors, can also promote the development and progression of cancer. An understanding of the interrelationship between cardiovascular diseases and cancer can be seen as a major medical challenge for the future. To this end, scientific, structural, clinical and educational interfaces between cardiology and oncology are essential. This article outlines the complex relationships between cardiovascular diseases and cancer and defines current and future challenges for the best possible care of affected patients.

Concealed Inherited Cardiomyopathies Detected in Cardio-Oncology Screening

INTRODUCTION

Basal cardiovascular risk assessment in cardio-oncology is essential. Integrating clinical information, ECG and transthoracic echocardiogram can identify concealed inherited cardiomyopathies (ICMPs) with potential added risk of cardiotoxicity. We aimed to evaluate the impact of our Cardio-Oncology Unit design in detecting concealed ICMPs.

METHODS

We carried out a retrospective study of all consecutive breast cancer patients referred to the Cardio-Oncology Unit for cardiac evaluation (2020-2022). ICMPs diagnosis was provided according to ESC guidelines and underwent genetic testing. ICMPs prevalence in this cohort was compared to the highest and lowest frequency reported in the general population.

RESULTS

Among 591 breast cancer patients, we identified eight patients with ICMPs: one arrhythmogenic cardiomyopathy (ACM), three familial non-ischemic dilated cardiomyopathy (DCM), three hypertrophic cardiomyopathy (HCM) and one left ventricular non-compaction cardiomyopathy (LVNC), which has now been reclassified as non-dilated left ventricular cardiomyopathy. The number of ICMPs identified was within the expected range (neither overdiagnosed nor overlooked): ACM 0.0017 vs. 0.0002-0.001 (p 0.01-0.593); DCM 0.0051 vs. 0.002-0.0051 (p 0.094-0.676); HCM 0.005 vs. 0.0002-0.002 (p < 0.001-0.099); LVCN 0.0017 vs. 0.00014-0.013 (p 0.011-0.015). Genetic testing identified a pathogenic FLNC variant and two pathogenic TTN variants.

CONCLUSION

Opportunistic screening of ICMPs during basal cardiovascular risk assessment can identify high-risk cancer patients who benefit from personalized medicine and enables extension of prevention strategies to all available relatives at concealed high cardiovascular risk.

Developing Cardio-Oncology Programs in the New Era: Beyond Ventricular Dysfunction Due to Cancer Treatments

Cardiovascular disease is a common problem in cancer patients that is becoming more widely recognized. This may be a consequence of prior cardiovascular risk factors but could also be secondary to the anticancer treatments. With the goal of offering a multidisciplinary approach to guaranteeing optimal cancer therapy and the early detection of related cardiac diseases, and in light of the recent ESC Cardio-Oncology Guideline recommendations, we developed a Cardio-Oncology unit devoted to the prevention and management of these specific complications. This document brings together important aspects to consider for the development and organization of a Cardio-Oncology program through our own experience and the current evidence.

Geographical Variation in Underlying Social Deprivation, Cardiovascular and Other Comorbidities in Patients with Potentially Curable Cancers in England: Results from a National Registry Dataset Analysis

AIMS

To describe the prevalence of cardiovascular disease (CVD), multiple comorbidities and social deprivation in patients with a potentially curable cancer in 20 English Cancer Alliances.

MATERIALS AND METHODS

This National Registry Dataset Analysis used national cancer registry data and CVD databases to describe rates of CVD, comorbidities and social deprivation in patients diagnosed with a potentially curable malignancy (stage I-III breast cancer, stage I-III colon cancer, stage I-III rectal cancer, stage I-III prostate cancer, stage I-IIIA non-small cell lung cancer, stage I-IV diffuse large B-cell lymphoma, stage I-IV Hodgkin lymphoma) between 2013 and 2018. Outcome measures included observation of CVD prevalence, other comorbidities (evaluated by the Charlson Comorbidity Index) and deprivation (using the Index of Multiple Deprivation) according to tumour site and allocation to Cancer Alliance. Patients were allocated to CVD prevalence tertiles (minimum: <33.3rd percentile; middle: 33.3rd to 66.6th percentile; maximum: >66.6th percentile).

RESULTS

In total, 634 240 patients with a potentially curable malignancy were eligible. The total CVD prevalence for all cancer sites varied between 13.4% (CVD n = 2058; 95% confidence interval 12.8, 13.9) and 19.6% (CVD n = 7818; 95% confidence interval 19.2, 20.0) between Cancer Alliances. CVD prevalence showed regional variation both for male (16-26%) and female patients (8-16%) towards higher CVD prevalence in northern Cancer Alliances. Similar variation was observed for social deprivation, with the proportion of cancer patients being identified as most deprived varying between 3.3% and 32.2%, depending on Cancer Alliance. The variation between Cancer Alliance for total comorbidities was much smaller.

CONCLUSION

Social deprivation, CVD and other comorbidities in patients with a potentially curable malignancy in England show significant regional variations, which may partly contribute to differences observed in treatments and outcomes.

Exploration of current pharmacy practice in cardio-oncology: Experiences & perspectives

INTRODUCTION

Cardiovascular complications can occur in oncology patients secondary to certain cancer therapies. Pharmacists are involved in the care of oncology patients who are at risk of or experiencing cardiotoxicity related to their cancer therapy. Our study aimed to understand how pharmacists in Canada care to these patients and to explore their experiences, perceptions, and challenges.

METHODS

Canadian pharmacists currently involved in the care of patients receiving cancer treatments and at risk of or experiencing cardiotoxicity were invited to participate in a 30-min telephone interview using an interview guide. A combination of inductive and deductive reasoning was applied using two coders who independently reviewed the transcribed interviews and identified key concepts and themes.

RESULTS

Eight pharmacists were interviewed. Perceived benefits included sharing specialized knowledge and conducting safety assessments. Perceived challenges were the lack of role recognition and resources and fractured continuity of care. Proposed future directions were to play a more substantial role in direct medication management, creation of specific guidance and tools to support the clinical decision-making process, and to understand how pharmacists at other sites were providing care through the creation of a community of practice.

CONCLUSIONS

As patient-focused medication specialists, pharmacists help guide clinical decision-making, assess cardiac risk factors, and offer individualized education to meet the holistic needs of oncology patients at risk of or experiencing cardiotoxicities. The creation of a cardio-oncology community of practice may allow pharmacists with a common interest to connect, share learnings, and collaborate on how to continue to advance the delivery of care.

The Essential Strategies to Mitigate Cardiotoxicity Caused by Doxorubicin

The study of mechanisms underlying cardiotoxicity of doxorubicin and the development of strategies to mitigate doxorubicin-induced cardiotoxicity are the most relevant issues of modern cardio-oncology. This is due to the high prevalence of cancer in the population and the need for frequent use of highly effective chemotherapeutic agents, in particular anthracyclines, for optimal management of cancer patients. However, while being a potent agent to counteract cancer, doxorubicin also affects the cardiovascular systems of patients undergoing chemotherapy in a significant and unfavorable fashion. Consecutively reviewed in this article are risk factors and mechanisms of doxorubicin cardiotoxicity, and the essential strategies to mitigate cardiotoxic effects of doxorubicin treatment in cancer patients are discussed.

Mild Cardiotoxicity and Continued Trastuzumab Treatment in the Context of HER2-Positive Breast Cancer

Breast cancer is the leading cause of cancer death in women worldwide. Trastuzumab, the main HER2-targeted treatment, faces limitations due to potential cardiotoxicity. The management of patients with mild cardiotoxicity on trastuzumab remains uncertain, resulting in treatment discontinuation and negative oncological outcomes. This retrospective study analyzed 23 patients who experienced decreased left ventricular function during trastuzumab treatment. During the 18-month follow-up period, two patients (9%) had severe declines in function, leading to treatment cessation, and one patient (4%) developed heart failure symptoms. However, 21 patients showed mild, reversible myocardial dysfunction without significant differences in final ventricular function compared to a control group (58.4% vs. 61.7%, respectively; p = 0.059). The declines in function were most pronounced at nine months but improved at twelve and eighteen months. Various echocardiographic parameters changed significantly over time. As predictors of severe cardiotoxicity, we identified the following: LVEF before initial chemotherapy (p = 0.022), as well as baseline LVEF before treatment with trastuzumab (p = 0.007); initial left ventricular end systolic volume (p = 0.027); and the initial global longitudinal strain (p = 0.021) and initial velocity time integral in the left ventricular outflow track (p = 0.027). In conclusion, the continuation of trastuzumab should be considered for most patients with mild cardiotoxicity, with close cardiac monitoring and cardioprotective measures. However, identifying the patients at risk of developing severe cardiotoxicity is necessary. According to our data, the initial LVEF and GLS levels appear to be reliable predictors.

Developing a Clinical Cardio-Oncology Program and the Building Blocks for Success: JACC: CardioOncology How To

•Cardio-oncology programs are necessary to provide optimal cardiovascular care to cancer patients and survivors.•Focus on developing a clear vision and mission-successful programs must be tailored to an organization's unique landscape.•Fostering partnerships with cardiologists and oncologists to provide high-quality patient-centered care is crucial.•Patience is essential-program development takes time, but success can be achieved.

Global Cardio Oncology Registry (G-COR): Registry Design, Primary Objectives, and Future Perspectives of a Multicenter Global Initiative

BACKGROUND

Global collaboration in cardio-oncology is needed to understand the prevalence of cancer therapy-related cardiovascular toxicity in different risk groups, practice settings, and geographic locations. There are limited data on the socioeconomic and racial/ethnic disparities that may impact access to care and outcomes. To address these gaps, we established the Global Cardio-Oncology Registry, a multinational, multicenter prospective registry.

METHODS

We assembled cardiologists and oncologists from academic and community settings to collaborate in the first Global Cardio-Oncology Registry. Subsequently, a survey for site resources, demographics, and intention to participate was conducted. We designed an online data platform to facilitate this global initiative.

RESULTS

A total of 119 sites responded to an online questionnaire on their practices and main goals of the registry: 49 US sites from 23 states and 70 international sites from 5 continents indicated a willingness to participate in the Global Cardio-Oncology Registry. Sites were more commonly led by cardiologists (85/119; 72%) and were more often university/teaching (81/119; 68%) than community based (38/119; 32%). The average number of cardio-oncology patients treated per month was 80 per site. The top 3 Global Cardio-Oncology Registry priorities in cardio-oncology care were breast cancer, hematologic malignancies, and patients treated with immune checkpoint inhibitors. Executive and scientific committees and specific committees were established. A pilot phase for breast cancer using Research Electronic Data Capture Cloud platform recently started patient enrollment.

CONCLUSIONS

We present the structure for a global collaboration. Information derived from the Global Cardio-Oncology Registry will help understand the risk factors impacting cancer therapy-related cardiovascular toxicity in different geographic locations and therefore contribute to reduce access gaps in cardio-oncology care. Risk calculators will be prospectively derived and validated.

Multimodality imaging in cardio-oncology: the added value of CMR and CCTA

During the last 30 years, we have assisted to a great implementation in anticancer treatment with a subsequent increase of cancer survivors and decreased mortality. This has led to an ongoing interest about the possible therapy-related side-effects and their management to better guide patients therapy and surveillance in the chronic and long-term setting. As a consequence cardio-oncology was born, involving several different specialties, among which radiology plays a relevant role. Till the end of August 2022, when European Society of Cardiology (ESC) developed the first guidelines on cardio-oncology, no general indications existed to guide diagnosis and treatment of cancer therapy-related cardiovascular toxicity (CTR-CVT). They defined multimodality imaging role in primary and secondary prevention strategies, cancer treatment surveillance and early CTR-CVT identification and management. Cardiac computed tomography angiography (CCTA) has acquired a central role in coronary assessment, as far as coronary artery disease (CAD) exclusion is concerned; but on the side of this well-known application, it also started to be considered in left ventricular function evaluation, interstitial fibrosis quantification and cardiac perfusion studies. Cardiac magnetic resonance (CMR), instead, has been acknowledged as the gold standard alternative to trans-thoracic echocardiography (TTE) poor acoustic window in quantification of heart function and strain modifications, as well as pre- and post-contrast tissue characterization by means of T1-T2 mapping, early Gadolinium enhancement (EGE), late Gadolinium enhancement (LGE) and extracellular volume (ECV) evaluation. Our review is intended to provide a focus on the actual role of CMR and CCTA in the setting of a better understanding of cardiotoxicity and to draw some possible future directions of cardiac imaging in this field, starting from the recently published ESC guidelines.

Uncommon short- and long-term cardiological side effects of thoracic radiation: a report of two cases

Radiotherapy is an essential treatment of more than 50% of oncohematological patients. Pericardial disorders and valvular heart disease are two common radiotherapy complications. Acute pericarditis is infrequent and usually underdiagnosed. Therefore, diagnostic suspicion and early treatment are mandatory to avoid the evolution to constrictive pericarditis. The prevalence of radiation-induced valvular heart disease is common in patients with a history of Hodgkin's lymphoma and breast cancer. It has distinctive characteristics from other etiologies and, thus, different therapeutic approaches. We present two cases of unusual complications of radiotherapy; the first one in the acute setting and the second one during the follow-up in the chronic phase. A multidisciplinary and individualized approach with specific considerations is decisive in the management of these patients.

Cardio-Oncology for the Primary Care Provider

Cardiovascular disease is a major cause of mortality among oncologic patients. As cancer therapies continue to evolve and advance, cancer survival rates have been increasing and so has the burden of cardiovascular disease within this population. For this reason, cardio-oncology plays an important role in promoting multidisciplinary care with the primary care provider, oncology, and cardiology. In this review, we discuss the roles of different providers, strategies to monitor patients receiving cardiotoxic therapies, and summarize cancer therapy class-specific toxicities. Continued collaboration among providers and ongoing research related to cardiotoxic cancer therapies will enable patients to receive maximal, evidence-based, comprehensive care.

Risk and Management of Patients with Cancer and Heart Disease

Cancer and cardiovascular disease are two of the leading causes of global mortality and morbidity. Medical research has generated powerful lifesaving treatments for patients with cancer; however, such treatments may sometimes be at the expense of the patient's myocardium, leading to heart failure. Anti-cancer drugs, including anthracyclines, can result in deleterious cardiac effects, significantly impacting patients' functional capacity, mental well-being, and quality of life. Recognizing this, recent international guidelines and expert papers published recommendations on risk stratification and care delivery, including that of cardio-oncology services. This review will summarize key evidence with a focus on anthracycline therapy, providing clinical guidance for the non-oncology professional caring for a patient with cancer and heart failure.

Established and Emerging Cancer Therapies and Cardiovascular System: Focus on Hypertension-Mechanisms and Mitigation

Cardiovascular disease and cancer are 2 of the leading causes of death worldwide. Although improvements in outcomes have been noted for both disease entities, the success of cancer therapies has come at the cost of at times very impactful adverse events such as cardiovascular events. Hypertension has been noted as both, a side effect as well as a risk factor for the cardiotoxicity of cancer therapies. Some of these dynamics are in keeping with the role of hypertension as a cardiovascular risk factor not only for heart failure, but also for the development of coronary and cerebrovascular disease, and kidney disease and its association with a higher morbidity and mortality overall. Other aspects such as the molecular mechanisms underlying the amplification of acute and long-term cardiotoxicity risk of anthracyclines and increase in blood pressure with various cancer therapeutics remain to be elucidated. In this review, we cover the latest clinical data regarding the risk of hypertension across a spectrum of novel anticancer therapies as well as the underlying known or postulated pathophysiological mechanisms. Furthermore, we review the acute and long-term implications for the amplification of the development of cardiotoxicity with drugs not commonly associated with hypertension such as anthracyclines. An outline of management strategies, including pharmacological and lifestyle interventions as well as models of care aimed to facilitate early detection and more timely management of hypertension in patients with cancer and survivors concludes this review, which overall aims to improve both cardiovascular and cancer-specific outcomes.

Cancer and Postradiotherapy Cardiotoxicity: How to Face Damage in Women’s Hearts?

Cancer and cardiovascular disease are the two main causes of death worldwide in both men and women. In the past decades, survival rate in cancer patients has substantially improved due to new treatments and developments in radiation therapy (RT). In women, breast cancer (BC) is the leading cause of cancer death and thoracic RT is a main component of the treatment in many cases. Nevertheless, despite new techniques that limit the area receiving RT, cardiac damage is still an important concern in BC patients. In this review, the following aspects will be addressed: pathophysiology of postradiotherapy heart damage in women with BC; mechanisms, diagnosis and prevention/management of heart damage; and future areas of potential research for radiotherapy injury in women.

Comparison of American and European guidelines for cardio-oncology of heart failure

Heart failure is a complex clinical syndrome, whose signs and symptoms are caused by functional or structural impairment of ventricular filling or ejection of blood. Due to the interaction among anticancer treatment, patients' cardiovascular background, including coexisting cardiovascular diseases and risk factors, and cancer itself, cancer patients develop heart failure. Some drugs for cancer treatment may cause heart failure directly through cardiotoxicity or indirectly through other mechanisms. Heart failure in turn may make patients lose effective anticancer treatment, thus affecting the prognosis of cancer. Some epidemiological and experimental evidence shows that there is a further interaction between cancer and heart failure. Here, we compared the cardio-oncology recommendations among heart failure patients of the recent 2022 American guidelines, 2021 European guidelines, and 2022 European guidelines. Each guideline acknowledges the role of multidisciplinary (cardio-oncology) discussion before and during scheduled anticancer therapy.

Potential Role of Global Longitudinal Strain in Cardiac and Oncological Patients Undergoing Cardio-Oncology Rehabilitation (CORE)

Although shown to be effective in improving survival and quality of life in patients with cancer, some treatments are well-known causes of cardiotoxicity, such as anthracyclines, monoclonal antibodies against human epidermal growth factor receptor 2 (HER2) and radiotherapy. To prevent cardiovascular disease (CVD) in patients living with cancer, cardiologists and oncologists promoted the development of cardio-oncology, an interdisciplinary field which aims to further improving life expectancy in these patients. Cardio-oncology rehabilitation (CORE), through correction of risk factors, prescription of drug therapies and structured exercise programs, tries to improve symptoms, quality of life, cardiorespiratory fitness (CRF) and survival in patients with cancer. Different imaging modalities can be used to evaluate the real effectiveness of exercise training on cardiac function. Among these, the global longitudinal strain (GLS) has recently aroused interest, thanks to its high sensitivity and specificity for cardiac dysfunction detection due to advanced ultrasound programs. This review summarizes the evidence on the usefulness of GLS in patients with cancer undergoing cardiac rehabilitation programs.

In-hospital and one-year outcomes in cancer patients receiving percutaneous coronary intervention for acute myocardial infarction: A real-world study

BACKGROUND

Cancer and ischemic heart disease are the leading causes of mortality. The optimal management for patients with concomitant acute myocardial infarction (AMI) and cancer remains challenging.

OBJECTIVE

To evaluate in-hospital and 1-year adverse outcomes in cancer patients receiving percutaneous coronary intervention (PCI) to treat AMI.

METHODS

This was a single-center, retrospective cohort study, patients with cancer admitted to The First Affiliated Hospital of Xi'an Jiaotong University for AMI and discharged between January 2015 and June 2020 were analyzed. The outcomes were all-cause mortality at 1-year follow up and incidence of in-hospital adverse events, including arrhythmias, heart failure, major bleeding, stroke, and all-cause death.

RESULTS

A total of 119 patients were included, of these, 68 (57.1%) received PCI (PCI group) and 51 (42.9%) did not (non-PCI group). Patients in the PCI group had a lower incidence of in-hospital arrhythmias (22.1 vs. 39.2%; p = 0.042), major bleeding (2.9 vs. 15.7%; p = 0.013), and all-cause mortality (1.5 vs. 11.8%; p = 0.018) than those in non-PCI group. On 1-year follow-up, the PCI group had a lower all-cause mortality than the non-PCI group (log-rank test = 14.65; p < 0.001). Multivariable Cox regression showed that PCI is an independent protective factor (adjusted HR = 0.503 [0.243-0.947], p = 0.045) for cancer patients who have concomitant AMI.

CONCLUSION

Cancer patients receiving PCI for AMI had a lower risk of in-hospital adverse events and mortality as well as 1-year all-cause mortality compared to those who refused PCI. Our study therefore supports the use of PCI to improve prognosis of this selected group of patients.

Cardiac computed tomographic imaging in cardio-oncology: An expert consensus document of the Society of Cardiovascular Computed Tomography (SCCT). Endorsed by the International Cardio-Oncology Society (ICOS)

Cardio-Oncology is a rapidly growing sub-specialty of medicine, however, there is very limited guidance on the use of cardiac CT (CCT) in the care of Cardio-Oncology patients. In order to fill in the existing gaps, this Expert Consensus statement comprised of a multidisciplinary collaboration of experts in Cardiology, Radiology, Cardiovascular Multimodality Imaging, Cardio-Oncology, Oncology and Radiation Oncology aims to summarize current evidence for CCT applications in Cardio-Oncology and provide practice recommendations for clinicians.

Temporal trends in disease-specific causes of cardiovascular mortality amongst patients with cancer in the USA between 1999 and 2019

AIMS

We report disease-specific cardiovascular causes of mortality among cancer patients in the USA between 1999 and 2019, considering temporal trends by age, sex, and cancer site.

METHODS AND RESULTS

We used the Multiple Cause of Death database, accessed through the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research resource. We included 629 308 decedents with cardiovascular disease (CVD) recorded as the primary cause of death and active malignancy listed as a contributing cause of death. We created disease-specific CVD categories and grouped cancers by site. We calculated the proportion of CVD deaths attributed to each disease category stratified by sex, age, and cancer site. We also examined disease-specific temporal trends by cancer site. Ischaemic heart disease (IHD) was the most common cardiovascular cause of death across all cancer types (55.6%), being more common in men (59.8%), older ages, and in those with lung (67.8%) and prostate (58.3%) cancers. Cerebrovascular disease (12.9%) and hypertensive diseases (7.6%) were other common causes of death. The proportion of deaths due to heart failure was greatest in haematological (7.7%) and breast (6.3%) cancers. There was a decreasing temporal trend in the proportion of cardiovascular deaths attributed to IHD across all cancer types. The proportion of deaths due to hypertensive diseases showed the greatest percentage increase, with the largest change in breast cancer patients (+191.1%).

CONCLUSION

We demonstrate differential cardiovascular mortality risk by cancer site and demographics, providing insight into the evolving healthcare needs of this growing high-cardiovascular risk population.

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.

The new 2022 ESC Guidelines on Cardio-oncology and their impact on the Acute Cardiovascular Care Society

In this perspective piece on the recently published ESC Guidelines on Cardio-oncology and the Consensus Statements from the Acute Cardiovascular Care Association, we summarize key learning points regarding the management of acute cardiovascular disease in patients with cancer. This document outlines where other pre-existing ESC Guidelines can be applied to the management of acute cardiovascular disease in patients with cancer while simultaneously highlighting important gaps in knowledge that require further research.

Cancer and cardiovascular disease share common risk factors and often co-exist, especially in older patients. In addition, patients with cancer undergoing active treatment are exposed to multiple, potentially cardiotoxic drugs, which may manifest as a variety of cardiovascular events, including left-ventricular systolic dysfunction and heart failure, arrhythmias, hypertension, or acute venous and arterial vascular events.

Knowledge about potential causative cancer therapeutics is necessary for rapid recognition and management to improve cardiovascular outcomes and guide ongoing cancer treatment. Specifically, the importance of rapidly interrupting culprit cancer drugs is highlighted, as well as instituting standard guideline-based therapies for conditions such as acute heart failure and acute coronary syndromes [ST-elevation myocardial infarction and high-risk non-ST-elevation acute coronary syndrome (ACS)]. Given the high prevalence of thrombocytopenia and increased bleeding risk in patients with cancer, we are provided with platelet cut-offs for the use of different antiplatelet agents and anticoagulants for patients with ACS and atrial arrhythmias. In contrast, given the hypercoagulable milieu of cancer, we are provided information regarding types of anticoagulants, drug–drug interactions, and duration of anticoagulation in patients with acute venous thromboembolism, as well as for atrial fibrillation. They also discuss the diagnostic and treatment strategies for the unique cardiotoxicities seen with novel cancer therapeutics such as immune checkpoint inhibitors and chimeric receptor antigen T-cell therapy. Last, but not least, the authors emphasize that the care of these patients requires close collaboration between cardiology and oncology to maximize both cardiovascular and cancer outcomes.
