INFLUENCE OF AEROBIC AND RESISTANT LOAD ON THE RISK OF ATRIAL FIBRILLATION IN ARTERIAL HYPERTENSION AND PAROXYSMAL ATRIAL FIBRILLATION

Abstract

Aim. To study the influence of the two basic load types, aerobic exercise (AE) and resistant with weights (RW), on the course of atrial fibrillation, on echocardiographic, structural and functional parameters of the left ventricle and left atrium and on the frequency of atrial fibrillation (AF) onsets. Material and methods. We performed controlled study in 102 patients (45 women) with AH at the age 56±9 years with sinus rhythm and at least one known episode of AF. The patients were randomized to three groups for AE on thread-mill (n=34), for RW (n=34), and controls without any load (n=34).Results. As the study has shown, both types of load significantly improved structural and functional parameters of the left ventricle and atrium, and reduced the frequency of onset of AF comparing to controls. However, in 6 months of regular exercise the RW group had better diastolic function parameters of the left ventricle and the left atrium, and did not have any episodes of AF comparing to AE and controls. Systemic pressure and systolic parameters of the left ventricle did not differ in groups.Conclusion. Adherence in RW was better than AE group. Aftereffect in patients who stopped training was more significant than in stopped AE patients, which presented with higher peak of oxygen consumption in 9-minute thread-mill test in these patients with RW.
