ABSTRACT
The effects of chronic exercise training and diet modification on serum lipids and lipoproteins were measured in 17 hypertensive males and 41 normotensive males with documented coronary artery disease (CAD). Exercise consisted of aerobic activities which were performed at approximately 75-85% of the symptom-limited maximum heart rate for 30-40 minutes, three times weekly for 3 months. Each participant's diet was also controlled, the recommended daily intake of fat and cholesterol was no more than 40 g/day and 200 mg/day, respectively. Significant increases in estimated VO2max and total cholesterol/high density lipoprotein (HDL) and a significant decrease in serum triglycerides were documented after training. Significant differences in serum cholesterol and triglycerides between the nondiuretic and diuretic patients were also noted. No significant changes were found in low density lipoprotein (LDL), HDL, or body weight. Vigorous aerobic training and diet modification can favorably modify the deleterious effects of diuretic medications on serum triglycerides and total cholesterol/HDL in patients with documented CAD.
