Brief Summary:

Patients with coronary artery disease are characterized by an increased cardiovascular risk and they often have low blood high density lipoprotein (HDL)-cholesterol levels or HDL-cholesterol with modified vasculoprotective properties.

The purpose of the present study is to characterize the quality of HDL-cholesterol in patients with coronary artery disease and normal blood HDL-cholesterol levels and to examine the effect of exercise training on the vasculoprotective effects of HDL-cholesterol in these patients. Additionally, the researchers aim to investigate the endothelial function, oxidative stress and the regenerative capacity of the endothelial progenitor cells in patients with coronary artery disease and the changes dependent on physical activity of patients.


Condition or disease Intervention/treatment
Coronary Artery Disease Behavioral: physical exercise

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 30 participants
Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Official Title: Randomized, Clinical Trial to Study the Effect of Exercise Training on the Function of HDL-Cholesterol, Endothelial Function, Oxidative Stress and Regenerative Capacity of Endothelial Progenitor Cells in Patients With Coronary Artery Disease

Primary Outcome Measures :
  1. vasculoprotective and regenerative functions of HDL-cholesterol before and after 8-weeks of exercise training
