[Characteristics and assessment of clinical course of ischemic heart disease after aortocoronary bypass surgery].

The features of the clinical course of coronary heart disease were examined in 325 patients 40.24 +/- 1.4 months after coronary bypass grafting. Based on the results of the comprehensive examination of the patients, its following patterns were identified: 1) asymptomatic without myocardial ischemia (30.8%); 2) asymptomatic in the presence of silent ischemia (3.5%); 3) effort angina pectoris (36.0%); 4) effort-and-rest angina (17.8%); 5) non-coronarogenic pain syndrome (11.7%), that is the patients in whom myocardial ischemia could not be provoked. The objective assessment of the patient's status in the preoperative period was demonstrated to predict a postoperative prognosis to a greater extent. Arterial hypertension and two prior myocardial infarctions, the number of diseased coronary arteries, the overall cardiac artery lesions and residual myocardial reserve were ascertained to be the most informative clinicofunctional measures in the assessment of the clinical course of coronary heart disease.
