[Lipid metabolic characteristics of young adults with ischemic heart disease]. 
Lipid metabolism was studied in 166 patients under 40 years of age suffering from myocardial infarction.  Marked changes were revealed in the condition of lipid metabolism: hyperlipoproteinemia, hypercholesterolemia, hypertriglyceridemia, increased level of free fatty acids.  In some cases, atherosclerosis of the coronary arteries was confirmed by the results of selective coronarography; hyperlipidemia was found more frequently than changes in the coronarograms.
