AIMS: Patients with type 2 diabetes mellitus (T2DM) suffer from accelerated coronary artery disease. We assessed the effects of a multifactorial intervention with focus on exercise training on coronary endothelial function, vascular structure, and inflammation in serum and skeletal muscle biopsies, including mRNA expression of diabetes candidate genes. METHODS AND RESULTS: Twenty-three patients were randomized to either 4 weeks in-hospital exercise training (6 x 15 min bicycle/day, 5 days/week) and a hypocaloric diet, followed by a 5 months ambulatory program (30 min ergometer/day, 5 days/week, plus 1 h group exercise/week), or a control group. At the beginning of the study, at 4 weeks, and after 6 months changes in diameter of coronary arteries in response to acetylcholine and mean peak flow velocity were invasively measured; intramural plaques were assessed by intravascular ultrasound. Six months of intervention led to significant improvement of coronary endothelial function, whereas intramural plaque burden remained unchanged. After 4 weeks, endothelial function remained unchanged, however, lowest values for fasting glucose, HbA1c, high-sensitive C-reactive protein, total and LDL-cholesterol, and highest values for mRNA expression in skeletal muscle of p22, gp91, haem oxygenase 1, peroxisome proliferator activator receptor (PPAR) alpha and gamma were observed. There was a continuous increase for AdipoR1, AdipoR2, Glut4, interleukin-6, endothelial nitric oxide synthase, and PPARgamma-coactivator-1alpha mRNA expression in skeletal muscle. CONCLUSION: This is the first study to demonstrate improvement in coronary endothelial function by a multifactorial intervention which focused on exercise training in patients with T2DM. This coincided with improved markers of hyperglycaemia, insulin sensitivity, and inflammation both in serum and skeletal muscle biopsies. |
