[Fate of ischemic heart disease patients depending on the nature of the coronary artery lesion].
The natural course of ischemic heart disease was followed up in 240 patients in periods of 1 to 7 years (average follow-up period 3 years). In all patients the character of affection of the coronary arteries was verified by angiography. The coronary arteries were normal or had mild changes in 27 patients. Obstruction of arteries (50 to 100%) was found in 189 patients. The study made it possible to establish the prognostic significance of angiographic and clinical data. Survival was highest when the coronary arteries were normal or only mildly changed as well as in isolated affection of a single artery. The disease followed a severe course with high mortality in involvement of three coronary arteries with grade III--IV stenosis.
