THE PREDICTIVE VALUE OF THE INDEX BAEVSKY AND ITS RELATIONSHIP WITH CLINICAL AND FUNCTIONAL DATA IN PATIENTS WITH ISCHEMIC HEART DISEASE

Objective: to evaluate the prognostic significance Baevsky-index (BI), during the bicycle exercise test, in comparison with the data of coronary angiography (CAG) in patients with chronic ischemic heart disease. Material and methods: the study involved 116 patients with chronic ischemic heart disease (men - 84.5%) of them with angina pectoris functional class 2 - 47 (40.5%), functional class 3 - 69 (59.5 %) patients. The average age of the subjects = 56,99±9,29 years. From the 116 surveyed 62 (53.4%) patients had a history of myocardial infarction. More than 80% of the patients in the subsequent CAG were performed. Depending on the values of the BI patients were divided into 4 groups: 1gr. - 37 (31.9%) patients with BI <2.6; 2gr. - 31 (26.7%) patients with BI = 2.6-2.9; 3gr. - 40 (34.5%) of persons with BI = 3.0-3.5 and 4gr. - 8 (6.9%) patients with BI > 3.5. Results: more than 85% of the patients were characterized by the presence of excess weight, and in 4gr. - 100% of patients. Also in 4gr. patients, lipid profile, in comparison with those in groups 1-3, were slightly lower and atherogenic index (AI) - was the smallest. Analysis of the echocardiographic parameters, in addition to the relative left ventricular dilatation, testified about reducing the contractile function of the heart muscle, and a more severe diastolic dysfunction in patients 4gr. According bicycle exercise tests, it was found that patients 4gr. characterized by the lowest level of maximal oxygen consumption (MOC 4gr. = 3,46 ± 0,94 MET, that is 22.9%, 16.6% and 12.6% was lower than in groups 1-3, respectively), and with the growth of values BI noted decline in the index of Duke. According to the CAG, the average score on the SYNTAX score reaches a maximum value in people 4gr. Correlation analysis found an inverse relationship between the BI and the index of Duke (p>0,05). At the same time, by comparing the value of BI and CAG data, in particular the amount of vascular lesions, direct correlation was observed (p<0.05). Conclusion: Baevsky index has a direct correlation with the quantitative coronary lesion vessels and can be recommended as a predictor of more severe coronary lesions in patients with chronic ischemic heart disease in the outpatient practice.
