I RBH - First Brazilian Hypertension Registry.

BACKGROUND: A registry assessing the care of hypertensive patients in daily clinical practice in public and private centers in various Brazilian regions has not been conducted to date. Such analysis is important to elucidate the effectiveness of this care. OBJECTIVE: To document the current clinical practice for the treatment of hypertension with identification of the profile of requested tests, type of administered treatment, level of blood pressure (BP) control, and adherence to treatment. METHODS: National, observational, prospective, and multicenter study that will include patients older than 18 years with hypertension for at least 4 weeks, following up in public and private centers and after signing a consent form. The study will exclude patients undergoing dialysis, hospitalized in the previous 30 days, with class III or IV heart failure, pregnant or nursing, with severe liver disease, stroke or acute myocardial infarction in the past 30 days, or with diseases with a survival prognosis < 1 year. Evaluations will be performed at baseline and after 1 year of follow-up. The parameters that will be evaluated include anthropometric data, lifestyle habits, BP levels, lipid profile, metabolic syndrome, and adherence to treatment. The primary outcomes will be hospitalization due to hypertensive crisis, cardiocirculatory events, and cardiovascular death, while secondary outcomes will be hospitalization for heart failure and requirement of dialysis. A subgroup analysis of 15% of the sample will include noninvasive central pressure evaluation at baseline and study end. The estimated sample size is 3,000 individuals for a prevalence of 5%, sample error of 2%, and 95% confidence interval. RESULTS: The results will be presented after the final evaluation, which will occur at the end of a 1-year follow-up. CONCLUSION: The analysis of this registry will improve the knowledge and optimize the treatment of hypertension in Brazil, as a way of modifying the prognosis of cardiovascular disease in the country.
