BACKGROUND: Patients with acute myeloid leukemia (AML) treated with hypomethylating agents and venetoclax (HMA-VEN) may be at risk for cardiovascular complications. The incidence, associations, and prognostic implications of these events remain poorly defined.
OBJECTIVES: The purpose of this study was to evaluate the incidence, risk factors, and prognostic significance of major adverse cardiovascular events (MACE) in AML patients treated with HMA-VEN and to identify clinical and genetic predictors.
METHODS: We conducted a multicenter retrospective cohort study across 6 U.S. health care systems between January 2017 and July 2024. The study included 1,012 adults (mean age 69 ± 12.5 years; 57% male) with newly diagnosed or relapsed/refractory AML treated with HMA-VEN. The primary outcome was MACE, defined as atrial fibrillation, heart failure, left ventricular ejection fraction reduction, stroke/transient ischemic attack, acute coronary syndrome, angina, ventricular tachycardia/fibrillation, myocarditis, or cardiovascular death. The secondary outcome was noncardiac mortality. Variables associated with MACE and mortality were analyzed using Fine-Gray competing risk and Cox proportional hazards models.
RESULTS: MACE occurred in 20% of patients (n = 200), with a median time to first MACE of 120 days and a 12-month cumulative incidence of 17%. Atrial fibrillation (6%), stroke/transient ischemic attack (5%), left ventricular ejection fraction reduction (5%), and heart failure (4%) were most frequent. Diabetes independently predicted MACE (subdistribution HR: 1.4; 95% CI: 1.03-1.89; P = 0.031). In the matched cohort, MACE was associated with increased mortality (73% vs 56%; HR: 1.96; 95% CI: 1.59-2.42; P < 0.001).
CONCLUSIONS: MACE are frequent and occur early in patients with AML treated with HMA-VEN, particularly in patients with diabetes, and are associated with lower survival.
