Improvements of the lipoprotein profile after coronary bypass surgery: additional effects of an exercise training program.

We have followed physical working capacity and the plasma lipoprotein pattern in 37 males who underwent coronary artery surgery for severe disabling angina pectoris. In order to evaluate the effect of exercise training, 18 patients were randomized to a supervised bicycle training programme three times a week for 12 weeks starting 6 weeks after surgery. Before surgery, working capacity was severely reduced in all subjects. The mean HDL cholesterol level was low (0.8 +/- 0.2 mmol l-1) and the mean plasma LDL concentration moderately elevated (4.6 +/- 0.9 mmol l-1). In the non-training group, physical working capacity increased significantly, and 18 weeks after surgery reached a plateau about 45% above the preoperative values. In the training group, a further improvement to about 60% above preoperative levels was registered at the end of the training program. In the non-training group, HDL cholesterol concentrations rose rapidly to levels between 10 and 15% above the preoperative values. One year after surgery, HDL cholesterol levels were 20% higher than before surgery. There was a parallel rise in apolipoprotein A1 concentrations by about 10% which indicates that the increase in HDL occurred mainly in the lipid rich HDL2 subfraction. There were no changes in plasma lipids or in LDL cholesterol concentrations. In the training group, the increase in HDL was about 20% during the first 26 weeks. One year after surgery, HDL levels were 23% above preoperative values. In this group, we also registered a significant decrease in plasma triglyceride levels by about 25% after two months of exercise.(ABSTRACT TRUNCATED AT 250 WORDS)

In-hospital exercise therapy in patients with severe angina pectoris.

The authors evaluated physiologic, psychologic and metabolic effects of a nine-week in-hospital training program on 14 men with severe disabling angina pectoris. The exercise program consisted of intensive interval training on an ergometer bicycle for two 30 min sessions daily. The physical performance increased by about 40% (p less than 0.001). Plasma insulin levels were reduced and glucose tolerance improved significantly. There was a decrease in plasma triglyceride and low-density lipoprotein (LDL) cholesterol levels, but no change in high-density lipoprotein (HDL) cholesterol, apolipoprotein AI and B concentrations. Plasma triglyceride (p less than 0.05) and LDL cholesterol (p less than 0.05) levels remained low three weeks after completion of the training period and the physical performance remained improved (p less than 0.01) even six months post-training. Four of the patients who had been disabled for at least five months were able to return to work. The authors suggest that comparatively short and intensive in-hospital rehabilitation of patients with coronary heart disease may be an attractive alternative to prolonged training on an outpatient basis, especially in patients with severe angina pectoris.
