Cardio-oncology: a multidisciplinary approach for detection, prevention and management of cardiac dysfunction in cancer patients
Abstract
Cardiac dysfunction that develops during or after completion of cancer therapy is a growing health concern that should be addressed in a multidisciplinary setting. Cardio-oncology is a new discipline that focuses on screening, monitoring and treating cardiovascular disease during and after cancer treatment. A baseline cardiovascular risk assessment is essential. For high-risk patients, a tailored and detailed plan for cardiovascular management throughout treatment and beyond should also be established. Anthracycline and/or trastuzumab-containing chemotherapy and chest-directed radiation therapy are well known cardiotoxic cancer therapies. Monitoring for the development of subclinical cardiotoxicity is crucial for the prevention of clinical heart failure. Detecting a decreased left ventricular ejection fraction after cancer therapy might be a late finding; therefore, earlier markers of cardiac injury are being actively explored. Abnormal myocardial strain and increased serum cardiac biomarkers (e.g. troponins and natriuretic peptides) are possible candidates for this purpose. An important method for preventing heart failure is the avoidance or minimization of the use of cardiotoxic therapies. Decisions must balance the anti-tumo...Continue Reading

Cardiovascular Disease Pathophysiology
Cardiovascular disease involves several different processes that contribute to the pathological mechanism, including hyperglycemia, inflammation, atherosclerosis, hypertension and more. Vasculature stability plays a critical role in the development of the disease. Discover the latest research on cardiovascular disease pathophysiology here.

Cardiotoxicity
Cardiotoxicity refers to the muscle damage or dysfunction of heart electrophysiology caused by drug intake or due to disease complications. It is a well-known side effect of several cytotoxic drugs, especially of the anthracyclines and can lead to long term morbidity. Here is the latest research.
