[Data on repeated studies on the blood lipid levels in evaluating the severity of chronic ischemic heart disease].

During 3 years cholesterol, triglyceride and lipoprotein levels were repeatedly determined in the blood of 125 patients with coronary disease, and the severity of the disease was assessed with bicycle ergometry and coronarography. A relationship has been established between the severity of the disease and its course and the degree of disorders in the lipid metabolism. Group with stable normolipidemia (28%) showed less manifest symptoms of the disease and absence of rapid progression with new coronary accidents. Groups with hyperlipoproteinemia both stable (52.8%) and transient (19.2%) had predominantly severe forms of the disease running unfavourable course. The more frequent with severe and extended, according to angiography atherosclerosis of the coronaries and unfavourable course of disease were associated with hyperlipoproteinemia type II.
