The purpose of the study was to examine the capacities of correction of impaired lipid metabolism in patients with CHD receiving selective beta-adrenoblockers (beta-AB) by using an antiatherogenic milk-and-vegetable diet. According to the type of antiatherogenic diet, 67 patients were divided into 2 groups: 1) 42 patients were on an antiatherogenic vegetarian diet (a vegetarian group--VG) and 2) 25 patients received routine mixed diet No. 10c (a control group--CG). At the same time all the patients received similar antianginal drug therapy including the selective beta-AB atenolol in a dose of 50 mg/day. The vegetarian diet without special hypolipidemic therapy had a marked normalizing effect on the serum lipid spectrum in patients with CHD. Thus, in VG, by the end of treatment, the level of total cholesterol significantly decreased by 16% while in the controls it increased by 13%. High-density lipoprotein cholesterol increased in VG and decreased in CG, therefore the atherogenicity coefficient considerably rose. These were true for triglycerides and very low-density lipoprotein cholesterol. These parameters significantly decreased in VG (by more than 30%) and increased in CG (by 16%). Among the clinical symptoms, a more pronounced decrease in blood pressure in the patients on vegetarian diet and a more significant increase in their exercise tolerance. Balanced antiatherogenic milk-and-vegetable diet in patients with coronary heart disease prevents the hyperlipidemic effect caused by the selective beta-AB atenolol and it is an agent for preventing its negative effect on lipid metabolism.
