INVESTIGATING PREVALENCE OF ARTERIAL HYPERTENSION AS HIGH-RISK FACTOR IN PATIENTS WITH CORONARY HEART DISEASE ELIGIBLE FOR OFF-PUMP CORONARY BYPASS

Abstract

The aim of the study was to analyze the prevalence of arterial hypertension in patients with coronary heart disease eligible for coronary bypass surgery on a working heart.
 Participants and methods. This study included 991 patients (786 men, 205 women) whose average age was 64.3 ± 1.4, the variation range of age was from 39 to 84 years. All study participants underwent coronary bypass surgery on a working heart. The design of the article is based on the analysis of the frequency of arterial hypertension in different clinical groups: with one-, two- and multi-vessel lesions of the coronary arteries.
 Results. The prevalence of arterial hypertension as a leading cardiovascular risk factor for ischemic heart disease after surgical treatment by performing coronary bypass surgery on a working heart was studied. We analyzed the prevalence of arterial hypertension in all clinical groups of the study as one of the leading factors that aggravate the course of coronary heart disease. Under a prolonged history of the disease, arterial hypertension has the potential to impact the structure of coronary arteries, leading to the formation of "tortuous vessels" i. e. structural changes in the coronary arteries that rise a number of question for the cardiovascular surgeons, determining the choice of tactics of surgical treatment of coronary heart disease.
 It was established that the frequency of arterial hypertension as a concomitant pathology in ischemic heart disease, is significantly higher in clinical groups with two- and multi-vessel lesions of the coronary arteries, mainly among male patients. It was also found that myocardial infarction occurred significantly more often in patients with coronary heart disease in the clinical group with multi-vessel lesions compared to its frequency in the clinical groups with one- and two-vessel lesions of the coronary arteries.
 Conclusion. Arterial hypertension patients with coronary heart disease presented for coronary bypass surgery on a working heart is a quite prevalent comorbidity, the frequency of which is higher among male patients and in clinical groups with multi-vessel lesions of the coronary arteries (lesions ≥ 3).
