Abstract

BACKGROUND: Diabetic cardiomyopathy (DbCM) increases risk of overt heart failure in individuals with diabetes mellitus. Racial and ethnic differences in DbCM remain unexplored.

OBJECTIVES: The authors sought to identify racial and ethnic differences among individuals with type 2 diabetes mellitus, structural heart disease, and impaired exercise capacity.

METHODS: The ARISE-HF (Aldolase Reductase Inhibitor for Stabilization of Exercise Capacity in Heart Failure) trial is assessing the efficacy of an aldose reductase inhibitor for exercise capacity preservation in 691 persons with DbCM. Baseline characteristics, echocardiographic parameters, and functional capacity were analyzed and stratified by race and ethnicity.

RESULTS: The mean age of the study participants was 67.4 years; 50% were women. Black and Hispanic patients had lower use of diabetes mellitus treatments. Black patients had poorer baseline ventricular function and more impaired global longitudinal strain. Overall, health status was preserved, based on Kansas City Cardiomyopathy Questionnaire scores, but reduced exercise capacity was present as evidenced by reduced Physical Activity Scale for the Elderly (PASE) scores. When stratified by race and ethnicity and compared with the entire cohort, Black patients had poorer health status, more reduced physical activity, and a greater impairment in exercise capacity during cardiopulmonary exercise testing, whereas Hispanic patients also displayed compromised cardiopulmonary exercise testing functional capacity. White patients demonstrated higher physical activity and functional capacity.

CONCLUSIONS: Racial and ethnic differences exist in baseline characteristics of persons affected by DbCM, with Black and Hispanic study participants demonstrating higher risk features. These insights inform the need to address differences in the population with DbCM. (Safety and Efficacy of AT-001 in Patients With Diabetic Cardiomyopathy [ARISE-HF]; NCT04083339).
