Exercise Training Improves Coronary Endothelial Dysfunction in Diabetes Mellitus Type 2 and Coronary Artery Disease

Paracelsus Medical University (PMU)

Status and phase: Completed; Phase 4

Conditions: Coronary Artery Disease; Type 2 Diabetes Mellitus

Treatments: Behavioral: Exercise training

Study type: Interventional

Funder types: Other

Identifiers

About

Patients with type 2 diabetes mellitus suffer from accelerated coronary artery disease. We will assess the effects of exercise training on coronary endothelial function, vascular structure, and inflammation both in serum and skeletal muscle biopsies, as well as expression of diabetes candidate genes.

Sex: All

Ages: 50 to 80 years old

Volunteers: No Healthy Volunteers

Inclusion criteria
