Core Tip
Core Tip: Yu et al conducted a rare longitudinal study of right ventricle (RV) and left ventricular function in type 1 diabetes. The left ventricle initially presented with diastolic dysfunction, followed by a decline in systolic function. Then, RV dysfunction emerged concurrently with the onset of pulmonary vascular pathologies and structural cardiac changes. These data align with clinical evidence that, although its onset is delayed, right heart failure independently predicts outcomes in diabetic patients. Recognizing RV failure as a component of diabetic cardiomyopathy is thus crucial, as it can facilitate earlier disease screening of diabetes, guide therapeutic strategies, and advance our understanding of biventricular remodeling.
