[Disorders of lipid metabolism in sudden death from ischemic heart disease].

Type IV hyperlipoproteinemia and sharp increase in the concentration of free fatty acids in blood were revealed in most individuals who had died suddenly of ischemic heart disease. Beside increased lipolytic activity of the myocardium, accumulation of free fatty acids and triglycerides in the muscle tissue of the heart was revealed. The authors presume that the increase of the concentration of free fatty acids and tryglycerides, just as of their source in the affected myocardium, stimulates hypoxia and promotes electrical instability of the heart and sudden death.
