To study the changes in the stiffness of the arterial wall, vasomotor function of the endothelium, and appearance of new cases of atrial fibrillation (AF) in patients with arterial hypertension with long-term treatment with lisinopril. Material and method. 66 hypertensive patients with cardiac sinus rhythm at the age of 48-64 years (mean age 58.4±4.2 years) were included into the study. They were randomized into 2 groups: patients of group 1 (n=35) were prescribed lisinopril or a combination of lisinopril with hydrochlorothiazide over the 5-year follow-up; patients of group 2 (control) did not receive angiotensin converting enzyme inhibitors or angiotensin II receptor blockers. The follow-up duration was from September 2010 until June 2016. It included telephone calls once every 3 months and annual clinical, instrumental and laboratory examination. The new-onset AF was identified by the 24-hour Holter ECG monitoring results and by patient symptom diaries. Results. New-onset AF was registered in 2 patients (6%) in the lisinopril group and in 4 patients (13%) from the control group (p=0.001) over the 5-year follow-up. Lisinopril significantly reduced AF incidence in hypertensive patients. The patients on lisinopril were found to have no significant changes in the left ventricular mass index and left atrial size according to echocardiography done after the 5-year follow-up whereas in the patients of control group both parameters increased significantly. Lisinopril contributed to the maintenance of endothelial vasodilator function and prevented increase in arterial wall stiffness. Conclusion. Long term lisinopril treatment was found to significantly reduce the AF incidence in hypertensive patients over the 5-year follow-up. Lisinopril demonstrated organoprotective properties throughout the cardiovascular disease continuum and can be recommended for primary prevention of arrhythmia in hypertensive patients..
