Abstract

Introduction:

Arterial hypertension is a disease that has a high impact on cardiovascular mortality and morbidity; however, it is still insufficiently controlled.

Objectives:

To assess hypertension control in patients seen at a specialized clinic and to identify associated variables.

Method:

Cross-sectional study involving the analysis of medical records from 782 patients treated in a highly complex outpatient clinic. Inclusion criteria: age ≥18 years, diagnosed with hypertension, in treatment ≥6 months. Patients with secondary hypertension (104) and incomplete data (64) were excluded. The main outcome was blood pressure control (systolic <140 and diastolic <90 mmHg). The independent variables studied were: sociodemographic and clinical characteristics (use of drugs, comorbidities and laboratory tests). Pearson's χ2 tests, Fisher's test, Student's t and Wilcoxon-Mann-Whitney tests were performed in the bivariate analysis and logistic regression in the multiple analyses, adopting p≤0.05.

Results:

The prevalence of hypertensive control was 51.1%. It was associated with a lack of control: body mass index (OR = 1.038; 95% CI = 1.008 - 1.071), history of stroke (OR = 0.453; 95% CI = 0.245 - 0.821), left ventricular hypertrophy (OR = 1.765; 95% CI = 1.052 - 3.011), and number of medications (OR = 1.082; 95% CI = 1.033 - 1.136).

Conclusion:

About half of the hypertensive patients had their blood pressure controlled; clinical variables and target organ damage were associated with the control.
