The Effects of SGLTi on Diabetic Cardiomyopathy — SGLTi  

Type2 Diabetes Clinical Trial

Official title: The Effects of SGLT Inhibition on Diabetic Cardiomyopathy

Status Active, not recruiting

Clinical Trial Summary

Diabetic cardiomyopathy is associated with significant morbidity and mortality. It is considered as a cardiac muscle disorder secondary to diabetes mellitus (DM). Certain studies show the clinical benefit of SGLT-s inhibitors on reducing cardiovascular outcomes amongst patients with type II DM that go beyond the correction of hyperglycemic perse. Thus an observational imaging study is proposed to identify mechanistic insights of the drug group over cardiovascular events.

Clinical Trial Description

Diabetic cardiomyopathy is defined as ventricular dysfunction in diabetic patients in the absence of coronary artery disease and hypertension. It is considered as a cardiac muscle disorder due to the metabolic consequences of DM characterized by left ventricular hypertrophy, left ventricular diastolic dysfunction (in the early stage), and/or systolic dysfunction. To date, there is no specific treatment proven effective for the condition due to the incomplete understanding of the pathogenesis. Recent studies however prove the efficacy of SGLT-2 inhibitors on reducing the primary composite end point of cardiovascular outcomes including hospitalization for heart failure, cardiovascular death, and all-cause death amongst patients with type II DM. Such clinical benefit is apparently mainly stemmed from the reduction in heart failure related mortality and sudden cardiac death rather than the macro-vascular events such as myocardial infarct and stroke, suggesting addition benefits going beyond the correction of hyperglycemia perse. These studies thus raise the possibility that the drug may have direct effects on the myocardium that conferring the clinical benefit not related the modification of traditional risk factors such as glycemic control, lipid, blood pressure, and obesity. A single-arm, observational cardiac magnetic resonance imaging study is proposed in type II diabetic patients before and 2 months after initiation of dapagliflozin. The aim is to identify mechanistic insights leading to the unexpected clinical benefit of SGLT inhibition. ;
