Treatment of coronary heart disease by diet and exercise: Fasting and diurnal lipoproteins

Abstract

The effects of a combined exercise and low-fat dientary regimen were studied in 11 patients with angiographically documented coronary heart disease (cholesterol 233 mg/dl, triglycerides 158 mg/dl) and 13 comparable patients (cholesterol 224 mg/dl, triglycerides 174 mg/dl) on usual care. During one year, fasting serum lipoproteins were lowered to “ideal” levels in the intervention group (cholesterol 191 mg/dl, triglycerides 100 mg/dl, LDL-cholesterol 121 mg/dl). There was no change of triglycerides and cholesterol on usual care while LDL-cholesterol rose significantly. Neither regimen had any effect on HDL-cholesterol. Diurnal triglycerides as a presumptive measure of IDL in the intervention group were diminished by 39%. The study demonstrates the feasibility of a diet and exercise regimen to normalize midly elevated plasma lipid levels and thus to possibly affect the course of coronary heart disease without drugs.
