The efficacy of surgery was studied in relation to the clinical manifestations of ischemic heart disease and the extent of coronary artery involvement. The localization of myocardial infarction, which happened after the operation, and the effect of myocardial infarction on the general state and work fitness of patients with ischemic heart disease were determined. The positive effect of surgery in ischemic heart disease was observed more frequently in patients with typical angina pectoris than in patients with atypical pain syndrome. The favorable result of myocardial revascularization was observed more often in patients with a lesion of 1 and 2 coronary arteries than in those with a lesion of 3 arteries. The area of the reversibly changed myocardium, determined by mosaic ECG, significantly affects the outcome of the operation. The larger the area of myocardial involvement, the more important is the complete (maximum) revascularization of the myocardium. Clinical, coronarographic and mosaic ECG data should be considered when determining indications and contraindications for the surgical treatment of patients with ischemic heart disease.
