Purpose of Review HER2-targeted therapies have led to improved clinical outcomes in early and advanced breast cancer (BC). We review the long-term cardiotoxicity of HER2-targeted therapy in early and advanced BC, our current knowledge of cardiotoxicity of novel HER2-targeted therapies, and propose a cardiac monitoring (CM) strategy for this population. Recent Findings Long-term data from studies with HER2-targeted therapy in the adjuvant setting have failed to demonstrate an increase in cardiotoxicity over time, and rates of cardiotoxicity seen with novel HER2 agents remain low. Despite over a decade of experience with HER2-targeted therapy, CM in clinical practice is inconsistent in patients with early BC and almost non-existent in advanced BC. Summary Long-term follow-up of clinical trials with HER2-targeted agents in early and advanced BC has failed to demonstrate increased rates of cardiotoxicity over time, attesting to the long-term safety of this class of drugs for the majority of patients, although the long-term cardiac safety of newer HER2 agents in the non-clinical trial setting is largely unknown. We propose CM incorporating clinical history, cardiac imaging, and biomarkers.

Purpose of Review The purpose of this review is to summarize the epidemiology, mechanisms, and management of cardiovascular complications of Bruton’s Tyrosine Kinase inhibitors (BTKIs). Recent Findings Ibrutinib increases the risk of atrial fibrillation, bleeding, and hypertension compared with non-BTKI therapies. The evidence to support an association between ibrutinib and other cardiovascular complications including ventricular tachyarrhythmias or cardiomyopathy is limited. Ibrutinib metabolism can be inhibited by some medications used to treat cardiovascular complications. The cardiovascular effects of more selective BTKIs, such as acalabrutinib, remain to be determined. Summary Future research should address the mechanisms underlying the cardiovascular complications of BTKIs and how best to manage them. The risks and benefits of more selective BTKIs as compared with ibrutinib require further evaluation.

Purpose of Review Cardiovascular toxicity is a leading cause of mortality among cancer survivors and has become increasingly prevalent due to improved cancer survival rates. In this review, we synthesize evidence illustrating how common cancer therapeutic agents, such as anthracyclines, human epidermal growth factors receptors (HER2) monoclonal antibodies, and tyrosine kinase inhibitors (TKIs), have been evaluated in cardiomyocytes (CMs) derived from human-induced pluripotent stem cells (hiPSCs) to understand the underlying mechanisms of cardiovascular toxicity. We place this in the context of precision cardio-oncology, an emerging concept for personalizing the prevention and management of cardiovascular toxicities from cancer therapies, accounting for each individual patient’s unique factors. We outline steps that will need to be addressed by multidisciplinary teams of cardiologists and oncologists in partnership with regulators to implement future applications of hiPSCs in precision cardio-oncology. Recent Findings Current prevention of cardiovascular toxicity involves routine screenings and management of modifiable risk factors for cancer patients, as well as the initiation of cardioprotective medications. Despite recent advancements in precision cardio-oncology, knowledge gaps remain and limit our ability to appropriately predict with precision which patients will develop cardiovascular toxicity. Investigations using patient-specific CMs facilitate pharmacological discovery, mechanistic toxicity studies, and the identification of cardioprotective pathways. Studies with hiPSCs demonstrate that patients with comorbidities have more frequent adverse responses, compared to their counterparts without cardiac disease. Further studies utilizing hiPSC modeling should be considered, to evaluate the impact and mitigation of known cardiovascular risk factors, including blood pressure, body mass index (BMI), smoking status, diabetes, and physical activity in their role in cardiovascular toxicity after cancer therapy. Future real-world applications will depend on understanding the current use of hiPSC modeling in order for oncologists and cardiologists together to inform their potential to improve our clinical collaborative practice in cardio-oncology. Summary When applying such in vitro characterization, it is hypothesized that a safety score can be assigned to each individual to determine who has a greater probability of developing cardiovascular toxicity. Using hiPSCs to create personalized models and ultimately evaluate the cardiovascular toxicity of individuals’ treatments may one day lead to more patient-specific treatment plans in precision cardio-oncology while reducing cardiovascular disease (CVD) morbidity and mortality.

Purpose of Review Immune checkpoint inhibitors (ICIs) have improved the survival of several cancers. However, they may cause a wide range of immune-related adverse events (irAEs). While most irAEs are manageable with temporary cessation of ICI and immunosuppression, cardiovascular toxicity can be associated with high rates of morbidity and mortality. As ICIs evolve to include high-risk patients with preexisting cardiovascular risk factors and disease, the risk and relevance of ICI-associated cardiotoxicity may be even higher. Recent Findings Several cardiovascular toxicities such as myocarditis, stress cardiomyopathy, and pericardial disease have been reported in association with ICIs. Recent findings also suggest an increased risk of atherosclerosis with ICI use. ICI-associated myocarditis usually occurs early after initiation and can be fulminant. A high index of suspicion is required for timely diagnosis. Prompt treatment with high-dose corticosteroids is shown to improve outcomes. Summary Although the overall incidence is rare, ICI cardiotoxicity, particularly myocarditis, is associated with significant morbidity and mortality, making it a major therapy-limiting adverse event. Early recognition and prompt treatment with the cessation of ICI therapy and initiation of high-dose corticosteroids are crucial to improve outcomes. Cardio-oncologists will need to play an important role not just in the management of acute cardiotoxicity but also to reduce the risk of long-term sequelae.

Purpose of Review To give an overview of the role of social media (SoMe) in cardio-oncology during the COVID-19 pandemic. Recent Findings SoMe has been critical in fostering education, outreach, awareness, collaboration, dissemination of information, and advocacy in cardio-oncology. This has become increasingly evident during the COVID-19 pandemic, during which SoMe has helped share best practices, community, and research focused on the impact of COVID-19 in cardiology and hematology/oncology, with cardio-oncology at the interface of these two subspecialty fields. Summary A strength of SoMe is the ability to amplify a message in real-time, globally, with minimal investment of resources. This has been particularly beneficial for the emerging field of cardio-hematology/cardio-oncology, a field focused on the interplay of cancer and cardiovascular disease. SoMe field especially during the COVID-19 pandemic. We illustrate how social media has supported innovation (including telemedicine), amplification of healthcare workers’ voice, and illumination of pre-existing and continued health disparities within the field of cardio-oncology during the pandemic.

Purpose of Review This study aims to assess the current state of cardio-oncology in reference to advocacy efforts, access to care, and perspective of stakeholders in their ability to provide patient care as well as development of “across the aisle” synergy among cardiologists and oncologists and academic and non-academic centers in various worldwide locations. Recent Findings During the last decade, there has been a significant and diverse growth in cardio-oncology. We reviewed the experience from cardiologists and oncologists across different healthcare systems, the global trends, the role of collaborative networks, and the importance of advocacy efforts. Summary Cardio-oncology will continue to grow, but there is an unmet need to increase awareness, improve education, and expand access to care to larger segments of the cancer population in order to have a more significant impact on their health. The growing collaboration through professional societies and collaborative networks provides an opportunity to advance the cardiovascular care of cancer patients to meet the projected needs in a growing and more diverse population.

Purpose of Review Along with population aging, the incidence of both heart failure (HF) and cancer is increasing. However, little is known about new-onset cancer in HF patients. This review aims at showing recent discoveries concerning this subset of patients. Recent Findings Not only cancer and HF share similar risk factors but also HF itself can stimulate cancer development. Some cytokines produced by the failing heart induce mild inflammation promoting carcinogenesis, as it has been recently suggested by an experimental model of HF in mice. Summary The incidence of new-onset cancer is higher in HF patients compared to the general population, and it significantly worsens their prognosis. Moreover, the management of HF patients developing new-onset cancer is challenging, especially due to the limited therapeutic options for patients affected by both cancer and HF and the higher risk of cardiotoxicity from anticancer drugs.

Purpose of the ReviewAs the number of cancer survivors increases due to early screening and modern (antineoplastic) treatments, cancer treatment associated cardiotoxicity (CTAC) is becoming an increasing health burden that affects survival and quality of life among cancer survivors. Thus, clinicians need to identify adverse events early, in an effort to take suitable measures before the occurrence of permanent or irreversible cardiac dysfunction.Recent FindingsCardiac troponin (cTn) and B-type natriuretic peptide (BNP) have been proven to detect subclinical cardiotoxicity during antineoplastic treatment. As such, these cardio-specific biomarkers could predict which patients are at risk of developing CTAC even before the start of therapy. Nevertheless, there are inconsistent data from published studies, and the recommendations regarding the use of these biomarkers and their validity are mostly based on expert consensus opinion.SummaryIn this review, we summarize available literature that evaluates biomarkers of CTAC, and we encourage strategies that integrate circulating biomarkers and cardiac imaging in identifying cancer patients that are at high risk.

Purpose of Review The novel Coronavirus (2019-nCoV, COVID-19) is historically one of the most severe acute respiratory syndromes and pandemics to affect the globe in the twenty-first century. Originating in Wuhan, the virus rapidly spread and impacted subsets of populations with initial unclear risk factors contributing to worsening morbidity and mortality. Patients with diagnosis of cancer and undergoing treatment further represent a population at risk for worsening cardiopulmonary outcomes. This review explores specific risk factors, diagnoses, and treatment options that impact cardio-oncologic patients with COVID-19. Recent Findings Multiple studies globally, including Italy, China, and the USA, have documented severe outcomes. Cancer patients are at increased risk of cardiac injury which itself is a risk factor for mortality. Additionally, elderly cancer patients undergoing recent anti-cancer treatment may be at greater risk for sustaining worse outcomes, although data remains suboptimal in this population. Major gaps remain regarding risk associated with type of cancer and type of anti-cancer treatment, as well as the layered risk of cardiovascular disease and cancer. Immunomodulatory therapies used to treat cytokine release syndrome secondary to anti-cancer therapies, as well as other agents being traditionally used to treat cardiovascular and cancer disease states, are being investigated for treatment of COVID-19. Summary Hypertension, cardiovascular disease, diabetes, and cancer have been associated with more severe COVID-19 infection and worse outcomes. Patients undergoing anti-cancer therapy or those who have suffered from coronavirus infection may develop long-standing changes, not limited to pulmonary fibrosis, hyperlipidemia, and worsening atherosclerosis. Those undergoing anti-cancer therapy are at theoretically increased susceptibility for infection, with type of cancer not necessarily dictating outcome. A review of the literature of patients with cardiovascular and/or cancer disease is presented, as well as proposed strategies to attenuate risk regarding treatment, management, and surveillance in this vulnerable population.
