Epidemiology of Arterial Hypertension in Russian Federation – Importance of Choice of Criteria of Diagnosis

Abstract

Purpose. Assessment of prevalence of arterial hypertension (AH), need for prescription of antihypertensive therapy (AHT), and efficacy of AHT in Russian population in accordance with novel guideline of the American College of Cardiology/American Heart Association (“American recommendations”) on diagnosis and treatment of AH (2017).Materials and methods. Epidemiological study ESSE-RF (ЭССЕ-РФ) was carried out in 12 regions of Russian Federation (RF) with different climatic-geographic characteristics. Number of examined residents of RF aged 25–65 years was 20 652. The sample was stratified by  gender and age. Examination included anthropometry, laboratory tests, blood pressure (BP) measurement with the OMRON tonometer. The SCORE scale was used for evaluation of risk of development of cardiovascular diseases (CVD). In  American recommendations AH was defined as  follows: 1-st degree  – systolic BP (SBP) 130–139  and/or diastolic BP (DBP) 80–89 mm Hg, 2-nd degree – BP ≥140/90 mm Hg and/or presence of AHT. In recommendations of the European Society of Cardiology (2013, 2018) (“European recommendations”) AH was defined as BP ≥140/90 mm Hg and/or presence of AHT.Results. We analyzed data of examination of  20 607  participants – 7806 men (37.9%) and 12 801  women (62.1%). According to  European recommendations AH was diagnosed in 10 347  persons (50.2%)  – 3987 men (51.1%) men and 6 360 women (49.7%). According to American recommendations AH was registered in 14 853 persons (72.1%) – 6 059 men (77.6%) and 8 794 women (68.7%). AHT received 6324 persons (61.1% of those with AH); according to American recommendations, the onset of AHT was indicated to additional 620 persons with 1-st degree AH because of high CVD risk. Among all participants with AH (on and without AHT) strengthening of AHT for achievement of target BP level was required in 77.8 and 92.6% of patients according to European and American recommendations, respectively.Conclusion. Application of novel criteria of AH diagnosis from 2017 ACC/AHA guideline to Russian population would increase prevalence of AH up to 72.1%. Onset of AHT would be indicated in 13.8% of patients with 1-st degree AH, while in 93% of patients receiving AHT its strengthening would be required.
