INFLUENCE OF MYOCARDIUM LESIONS OF DIFFERENT DEGREES ON LEFT VENTRICLE DIASTOLIC FUNCTION IN PATIENTS-NORTHENERS WHO HAD CORONARY ARTERY BYPASS GRAFT
To evaluate the left ventricular diastolic function after coronary bypass surgery were performed in 65 patients, constantly living in condition of the European Russian North with varying myocardial involvement before and during 1-year operation. Doppler-echocardiography was performed in all patients. The study excluded patients with heart defects. Based on myocardial infarction in anamnesis, the patients were divided into 3 groups. Parameters of transmitral and pulmonary blood flow after coronary bypass surgery significantly improved in patients, who had a history of large myocardial infarction and in patients, who have not had it. Thus, coronary bypass surgery results in improved left ventricular diastolic function, which may be an additional criterion in assessing the adequacy of surgical intervention.
