Controlled and uncontrolled arterial hypertension: comparison of clinical and demographic characteristics in patients (according to the National Registry of Hypertension, 2019-2022)

Aim: to study the clinical and demographic characteristics of patients in a sample of patients with arterial hypertension observed in primary healthcare (20192022). To compare data from patients with uncontrolled and controlled hypertension.

Materials and methods. An analysis of medical data of 4543 patients was carried out (history, clinical and laboratory data, concomitant cardiovascular diseases, type 2 diabetes mellitus, chronic kidney disease, revascularization (coronary bypass grafting, transluminal balloon angioplasty of the coronary arteries). For statistical data processing, the SPSS statistical software package was used.

Results. The patients in the study sample were middle-aged and elderly. 51,5% of patients did not achieve target blood pressure values. More than 90% of patients in the studied sample are high and very high risk patients. The ratio of groups of patients with controlled and uncontrolled arterial hypertension among patients of different ages did not differ. Higher values of low-density lipoprotein cholesterol, a higher frequency (1,3 times) of failure to achieve target values of low-density lipoprotein cholesterol <2,6 mmol/l, and obesity (1,3 times) were identified in patients with uncontrolled arterial hypertension. More than 80% of patients had low-density lipoprotein cholesterol values higher than recommended. Patients with controlled arterial hypertension were more likely to have coronary heart disease, myocardial infarction and a history of coronary angioplasty and coronary artery bypass grafting.

Сonclusions. In hypertensive patients, more careful monitoring of cardiovascular risk factors is required, including blood pressure levels and achieving target LDL cholesterol levels. The association of a higher incidence of obesity, type 2 diabetes mellitus and the severity of dyslipidemia with uncontrolled hypertension may indicate less adherence of patients to both drug and non-drug treatment methods. While the presence of coronary heart disease, surgical interventions performed on the coronary arteries can serve as an illustration of increased adherence to therapy when hypertension is combined with coronary heart disease.
