Arterial hypertension in ryazan region: Data of the third section of the epoha study

Abstract

Aim. To study the nine-year dynamics of prevalence, risk factors, approaches to the treatment of arterial hypertension (AH) in the Ryazan region according to a representative sample survey, to assess the impact of risk factors and cardiovascular diseases on achieving blood pressure (BP) control. Material and methods. A representative sample of the population of the Ryazan region, created in 2002 by the method of step-by-step randomization, was reexamined in 2007 and 2016. The group of AH included people with blood pressure ≥140/90 mm Hg. with double measurement or normal blood pressure, receiving antihypertensive therapy. The role of risk factors (age, smoking, alcohol abuse, salt, obesity, burdened heredity, low physical activity) and cardiovascular diseases was analyzed. Results. In 2016, the prevalence of AH was 43,9%, the number of people receiving antihypertensive drugs — 89,5%, those who are treated effectively — 37,3%, which is higher than in 2007 (39,3%, 799% and 16,6%, respectively). Smoking (RR 1,23; 1,11-1,37, p=0,005), salt abuse (RR 1,11; 1,01-1,23, p=0,04) and obesity (RR 1,16; 1,06-1,27, p=0,003) negatively effect on the effectiveness of AH treatment. Treatment of AH is more effective in the absence of cardiovascular diseases (35,0% vs. 26,8%), signs of chronic heart failure (24,9% vs. 34,9%) and intermittent claudication (8,3% vs. 31,7%), p <0,001. Conclusion. Over nine years, the standardized by age prevalence of AH has increased significantly, the number of individuals taking antihypertensive drugs and the treatment effectively, the structure of the drugs taken has changed positively. Smoking, obesity, salt abuse and the presence of diseases of the cardiovascular system adversely affect the effectiveness of therapy.
