Adverse effects were not significantly different between the groups, and the most common events in each group included dizziness, dry mouth, symptomatic hypertension, stomachache, and nausea. Although the results suggest that carvedilol can reduce the risk of myocardial injury, more research is needed to address the question of the increase in troponin without change in the LVEF, Dr. Avila noted. The study is ongoing and the research team intends to follow the low-risk patient population for a total of 2 years. “For high-risk patients, I am already giving carvedilol,” she said. “We believe if we find a difference in LVEF or clinical events, we could encourage cardiologists to give carvedilol in a low-risk population,” she said.
“This study highlights that there is no safe dose of anthracycline,” commented Bonnie Ky, MD of the University of Pennsylvania, Philadelphia, at a press briefing. She emphasized the value of carvedilol for a high-risk population, and stressed the importance of following long-term changes in heart injury markers after 1-2 years for low-risk patients.
Dr. Avila had no financial conflicts to disclose. Dr. Ky disclosed relationships with multiple companies including Bioinvent and Bristol Myers.
The findings were published simultaneously in the Journal of the American College of Cardiology.
