Cancer and heart failure are the two leading causes of death in developed countries. These two apparently distinct clinical entities share similar risk factors, symptoms, and pathophysiological mechanisms (inflammation, metabolic disturbances, neuro-hormonal and immune system activation, and endothelial dysfunction). Beyond the well-known cardiotoxic effects of oncological therapies, cancer and heart failure are thought to be tied by a bidirectional relationship, where one disease favors the other and vice versa. In this context, biomarkers represent a simple, reproducible, sensitive and cost-effective method to explore such relationship. In this review, we recapitulate the evidence on cardiovascular and oncological biomarkers in the field of cardioncology, focusing on their role in treatment-naïve cancer patients. Cardioncological biomarkers are useful tools in risk stratification, early detection of cardiotoxicity, follow-up, and prognostic assessment. Intriguingly, these biomarkers might contribute to better understand the common pathophysiology of cancer and heart failure, thus allowing the implementation of preventive and treatment strategies in cardioncological patients
Longer life expectancy along with advancements in cancer and atrial fibrillation (AF) therapies and treatment strategies have led to an increase in the number of individuals with both diseases. As a result, the complicated management of these patients has become crucial, necessitating individualised treatment that considers the bi-directional relationship between these two diseases. On the one hand, giving appropriate pharmaceutical therapy is exceptionally difficult, considering the recognised thromboembolic risk posed by AF and malignancy, as well as the haemorrhagic risk posed by cancer. The alternative pulmonary vein isolation (PVI) ablation, on the other hand, has been inadequately explored in the cancer patient population; there is yet inadequate data to allow the clinician to unambiguously select patients that can undertake this therapeutic intervention. The goal of this review is to compile the most valuable data and supporting evidence about the characteristics, care, and therapy of cancer patients with AF. Specifically, we will evaluate the pharmaceutical options for a proper anticoagulant therapy, as well as the feasibility and safety of PVI in this population.
Since the introduction of anthracyclines into clinical practice in the 1960s, chemotherapy have always been associated to cardiotoxicity. Patients on cardiotoxic drugs can develop a wide range of cardiovascular diseases, including left ventricular (LV) systolic dysfunction and heart failure (HF), arrhythmias, hypertension, and coronary artery disease (CAD). The rising number of cancer patients, population aging, and the frequent overlap of cardiovascular and oncological diseases have highlighted the importance of close collaboration between cardiologists and oncologists. As a result, in 1995, cardiologists at the IEO (European Institute of Oncology) coined the term cardioncology, a new discipline focused on the dynamics of cardiovascular disease in cancer patients. Given the complex scenario characterized by a constant dialogue between the oncological condition and cardiovascular comorbidity, it is essential for the clinician to get the knowledge to properly fulfill the needs of the oncological patient under cardiotoxic treatment.
Through the answer to 10 questions, we aim to describe the complex issue of cardiotoxicity by addressing the main critical points and current evidence related to the assessment, management, treatment and surveillance of cancer patients under chemotherapy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
