Right ventricular dysfunction in type 1 diabetic cardiomyopathy: An overlooked component?
Abstract
While left ventricular (LV) impairment in diabetic cardiomyopathy is well recognized, the contribution of right ventricular (RV) dysfunction has received far less attention. In their longitudinal investigation, Yu et al systematically examined RV and LV performance in a type 1 diabetic mouse model and demonstrated that RV diastolic dysfunction develops later than LV abnormalities, coinciding with structural remodeling marked by fibrosis, hypertrophy, and mild pulmonary hypertension. These observations underscore the progressive yet distinct trajectory of RV pathology in diabetes and point to the importance of incorporating RV assessment into the overall cardiac evaluation of diabetic patients. This letter explores the broader significance of these findings and highlights the urgent need for studies focused on RV-specific mechanisms and targeted therapies aimed at preventing or attenuating biventricular injury in diabetic cardiomyopathy.
