Efficacy Evaluation of Glimepiride in Patients With Type 2 Diabetes Mellitus and Chronic Heart Failure With Reduced Ejection Fraction: A Multicenter, Randomized, Double-blind, Placebo-controlled Clinical Trial.

Evaluating the safety and efficacy of glimepiride in patients with type 2 diabetes and chronic heart failure with reduced ejection fraction--a multicenter randomized controlled study.

Study Overview

Detailed Description

Diabetes and heart failure share common pathophysiological mechanisms. The synergistic effects of managing both conditions, along with the potential for diabetes treatment to modulate the risk of heart failure outcomes, hold significant medical promise.Currently, the relationship between sulfonylureas,primarily including glimepiride, and heart failure outcomes remains poorly understood, with ongoing controversy regarding their cardiovascular effects in observational studies. No large-scale, randomized controlled trials have yet been conducted to validate the impact of sulfonylureas on patients with established heart failure. Our prospective cohort studies have preliminarily confirmed the cardioprotective effects of glimepiride in patients with type 2 diabetes complicated by chronic heart failure, demonstrating a favorable safety profile. Therefore, this study aims to conduct a prospective, multicenter, randomized, double-blind, placebo-controlled clinical trial to evaluate the therapeutic efficacy of glimepiride in patients with type 2 diabetes complicated by chronic heart failure.This study plan aims to recruit 1,484 eligible participants, who will be randomly assigned in a 1:1 ratio to either the glimepiride group or the placebo group. The total study duration is 36 months, with all participants required to complete baseline visits and outpatient follow-ups at months 1, 3, 6, 9, 12, 18, 24, 30 and 36.

  13. Patients refusing to comply with study requirements to complete the research;
  14. Conditions where the investigator deems the patient unable to understand and/or comply with study medications, procedures, or any other circumstances that may prevent completion of the study;
  15. Any other reason deemed inappropriate for inclusion by the study physician.
