Effects of antihyperlipidemic drugs and diet plus exercise therapy in the treatment of patients with moderate hypercholesterolemia.

We compared the efficacy of two antihyperlipidemic drugs and the efficacy of diet plus exercise therapy in the treatment of patients with moderate hypercholesterolemia. The study included 48 patients with moderate hypercholesterolemia (serum total cholesterol [TC], 250 to 320 mg/dL). Patients were divided into three groups: group A--patients administered 10 mg/d of pravastatin; group B--patients administered 500 mg/d of probucol and 600 mg/d of pantethine; and group C--patients administered diet plus exercise therapy. The serum TC and serum high-density lipoprotein cholesterol (HDL-C) values were determined via enzymatic methods before initiation of each therapy and after 4 and 8 weeks of therapy. An atherogenic index (AI) was also calculated. The results indicated that TC showed a statistically significant decrease in all three groups at 4 and 8 weeks (P < 0.001 and P < 0.05, respectively); the HDL-C value did not change significantly in groups A and C, but it had a statistically significant decrease in group B at 4 and 8 weeks. The AI showed a statistically significant decrease in group A at 4 and 8 weeks of treatment and group C at 8 weeks; there were no significant changes in AI in group B. It may be concluded that as an antihyperlipidemic agent, pravastatin is more useful than probucol and that appropriate exercise and strict dietary management for 8 weeks achieve an efficacy close to that achieved by drug therapy.
