[Surgical correction of hyperlipoproteinemia in patients with ischemic heart disease].

The experimental results obtained in 102 animals showing a beneficial effect of partial ileac bypass on hyperlipoproteinemia and experimentally-induced atherosclerosis prompted the authors to perform this surgical intervention in 34 patients with coronary heart disease (CHD) and attendant hyperlipoproteinemia resistant to therapeutic agents. The follow up period was up to five years. The patients exhibited a persistent and substantial decrease in blood lipids and atherogenic lipoproteins, a reduced incidence of angina attacks and an improved CHD course. Furthermore, the surgery resulted in a considerable and stable elevation of the cholesterol levels of antiatherogenic high density lipoproteins (by an average of 85,3%) and in a 45.8% decrease of the cholesterol coefficient of atherogenicity which contributes to atherosclerosis regression.
