THE ROLE OF VASODILATION FACTORS IN THE PATHOGENESIS OF CHRONIC HEART FAILURE OF ISCHEMIC ORIGIN IN ATRIAL FIBRILLATION
Abstract
The purpose of the study is to study the possible role of vasodilation factors in the pathogenesis of chronic heart failure (CHF) in persistent atrial fibrillation (AF) in patients with stable coronary heart disease. Materials and methods. A survey of 86 patients with stable coronary heart disease complicated by CHF II-III FC according to the NYHA classification. There was 1 group - 22 patients with CHF with reduced LV EF ≤ 40.0% and AF; I (comparative group) - 20 patients with CHF with reduced LV EF without AF; 2-nd group - 24 patients with preserved LV EF ≥ 40.1% and AF and II (comparative group) - 20 patients with CHF with preserved LV EF without AF. The content of endothelial nitric oxide synthase (eNOS), nitrites (NO2-) and nitrates (NO3-) was determined. All patients underwent electrocardiographic examination (ECG) for the initial screening of arrhythmias and conduction, diagnosis of focal changes in the ventricular myocardium. Structural and hemodynamic characteristics of the heart muscle were determined by echocardiography.
Results. In the examined patients of the 1st group with CHF of ischemic origin and reduced LV EF ≤ 40.0% and AF in comparison with the 2nd group of patients with CHF with preserved LV EF and AF, a significant increase in the values of ICO, ICD, IMML, the size of LA and a decrease in LV EF (p <0.01), indicating the development of LVH (remodeling) and a decrease in isotropic heart function. When comparing the levels of vasodilation factors in patients with CHF with low LV EF and AF and data from the CHF comparison group without AF, a significant decrease in eNOS by 96.8% (almost twice) and a significant decrease in serum nitrite and nitrate levels (p < 0.01), indicating the development of endothelial dysfunction. Conclusions. In patients with CHF of ischemic origin in the development of persistent forms of AF pathogenetic role is played by a significant decrease in vasodilating factors (content of eNOS, nitrites and nitrates). At decrease in EF of LV ≤ 40,0% there is a significant decrease in vasodilating factors, as a result of disturbance of endothelial function that testifies to need of correction of the revealed changes directed on slowing down of disease progression.
