Pioglitazone on Heart Failure in Type-2 Diabetes Mellitus Participants

Recruiting now · Phase 4 · Has a placebo group

Conditions studied: Type 2 Diabetes Mellitus in Obese, Heart Failure With Preserved Ejection Fraction

In brief

Our goal of the study is to learn the effects of the diabetes medication named Pioglitazone, in type-2 diabetic obese participants with Heart failure. The main question it aims to answer are: 1. To demonstrate that impaired mitochondrial function leading to reduced ATP generation plays a key pathophysiologic role in the development of heart failure with preserved ejection fraction (HFpEF) in obese type 2 diabetic (T2D) individuals. 2. To demonstrate that pioglitazone, improves diastolic (as well as systolic) function by improving myocardial insulin sensitivity and by reducing both myocardial and epicardial fat content.
