Abstract

Background: Sodium-glucose co-transporter-2 (SGLT2) inhibitors improve outcomes among patients with established heart failure. Despite supportive basic science studies, there are no data on the value of SGLT2 inhibitors among patients treated with anthracyclines. Objectives: This study sought to test the cardiac efficacy and overall safety of SGLT2 inhibitors in patients treated with anthracyclines. Methods: This study identified 3,033 patients with diabetes mellitus (DM) and cancer who were treated with anthracyclines. Cases were patients with cancer and DM who were on SGLT2 inhibitor therapy during anthracycline treatment (n = 32). Control participants (n = 96) were patients with cancer and DM who were also treated with anthracyclines, but were not on an SGLT2 inhibitor. The primary cardiac outcome was a composite of cardiac events (heart failure incidence, heart failure admissions, new cardiomyopathy [>10% decline in ejection fraction to <53%], and clinically significant arrhythmias). The primary safety outcome was overall mortality. Results: Age, sex, ethnicity, cancer type, cancer stage, and other cardiac risk factors were similar between groups. There were 20 cardiac events over a median follow-up period of 1.5 years. The cardiac event incidence was lower among case patients in comparison to control participants (3% vs 20%; P = 0.025). Case patients also experienced lower overall mortality when compared with control participants (9% vs 43%; P < 0.001) and a lower composite of sepsis and neutropenic fever (16% vs 40%; P = 0.013). Conclusions: SGLT2 inhibitors were associated with lower rate of cardiac events among patients with cancer and DM who were treated with anthracyclines. Additionally, SGLT2 inhibitors appeared to be safe. These data support the conducting of a randomized clinical trial testing SGLT2 inhibitors in patients at high cardiac risk treated with anthracyclines.
