While heart failure (HF) is an uncommon complication of breast cancer, a new study in the Journal of the American College of Cardiology notes individuals treated with trastuzumab-based chemotherapy have a higher risk for HF—but they are not monitored for it, despite recommendations.

As life expectancy continues to expand for cancer patients, clinicians are increasingly dealing with oncological complications like cardiotoxicity, according to a medical team in the Netherlands—and those doctors are met with a paucity of research on the topic.

Treating today’s cancer patient no longer means simply targeting the cancer. Given the known cardiotoxicities of some established chemotherapies and the possibility that newer approaches may damage the heart, oncologists, cardiologists and imaging specialists now work together to detect and minimize the risk of treatment-induced heart failure.

According to research presented during the 21st annual scientific sessions of the American Society of Echocardiography (ASE) in San Diego this week, cardiac troponin plasma concentrations and longitudinal strain can predict the development of cardiotoxicity in patients treated with anthracyclines and trastuzumab chemotherapies.
