Cardiac Testing to Manage Cardiovascular Risk in Cancer Patients

Cardiovascular toxicity is one of the most feared complications of cancer treatment. Recent advances in oncologic therapies have resulted in improved cancer outcomes but also a new set of cardiovascular adverse effects. Common toxicities include left ventricular dysfunction/heart failure, hypertension, and myocardial ischemia. Accurate risk stratification allows avoidance of potentially harmful treatments in those patients at greatest risk while maintaining the ability to deliver high doses of effective therapies to the lower-risk population. Cardiac investigations, including echocardiography, nuclear imaging, magnetic resonance imaging, biomarker measurement, blood pressure monitoring, electrocardiography, stress testing, and invasive angiography, can help to risk-stratify selected patients. In this review, common complications are discussed in terms of the factors used to identify patients with elevated risk, the monitoring strategies available, and selected interventions that have been used to modify outcomes in patients identified as being at high risk for cardiac complications of cancer treatment.
