Purpose: This review aims to highlight the different types of chemotherapy-induced cardiotoxicity and will discuss the evidence base behind the use of different cardiac biomarkers to predict cardiovascular complications. Additionally, we will review the use of cardiac biomarkers to monitor cardiac outcomes and the role of cardioprotective medications in reducing cardiovascular side effects.

Recent findings: Chemotherapy has been linked to an increased risk of cardiotoxicity and heart failure. Currently, patients receiving chemotherapy undergo echocardiogram before starting chemotherapy and every 6 months to monitor for any decline in cardiac function. We reviewed the current evidence and practice guidelines of monitoring chemotherapy cardiotoxicity.

Summary: Cardio-oncology is a rapidly evolving subspecialty in cardiology, especially with the advent of new chemotherapeutic agents, which have cardiovascular side effects. Early detection of these effects is crucial to prevent life-threatening and irreversible cardiovascular outcomes. Monitoring troponin, pro-brain natriuretic peptide, and other cardiac biomarkers during chemotherapy will help to early detect cardiotoxicity.
