The Effect of 48 Hours GLP-1 Infusion on Left Ventricular Function, Exercise Capacity, Insulin Sensitivity and Substrate Metabolism in Patients With Chronic Heart Failure
The Effect of 48 Hours GLP-1 Infusion on Left Ventricular Function, Exercise Capacity, Insulin Sensitivity and Substrate Metabolism in Patients With Chronic Heart Failure
The purpose of this study is to determine whether 48 hours of glucagon-like-peptide-1 (GLP-1) infusion can improve heart function and alter substrate metabolism in non-diabetic patients with heart failure.
Heart failure is a major complication in patients with ischemic heart disease. It has been shown that many of these patients have areas of viable myocardium that are not effectively contributing to heart function.
Further, chronic congestive heart failure is associated with some degree of insulin resistance in both skeletal and cardiac muscle.
GLP-1 is a naturally occurring peptide hormone that acts as an incretin and has been intensively studied by many groups in association with type II diabetes and it has clearly shown its glucose lowering potential with very little risk of hypoglycemia in several trials.
Recently GLP-1 has been shown to improve cardiac function in dogs with pace-induced cardiomyopathy, and in an open-labeled study it did improve cardiac function in patients with acute myocardial infarctions.
Comparison: 48 hours of treatment with intravenous GLP-1 compared to placebo. Effect on global and regional left ventricular function, exercise capacity, insulin sensitivity and substrate metabolism.
