Hypertension Control in Brazilian Publications

Abstract

Hypertension is a major public health problem due to its high prevalence and cardiovascular complications. Its treatment is aimed at reducing cardiovascular morbidity and mortality, its goal being to maintain blood pressure levels below 140/90 mm Hg. Hypertension control in Brazil is low, and nationwide rates are unknown. The objective of this review was to provide an overview on hypertension control in Brazil from publications in a database. We identified 45 publications. In population-based studies, the highest control rate (57.6%) was reported in a multicenter study in 100 municipalities and the city of São José do Rio Preto, São Paulo state (52.4%), while the lowest rates (around 10%) were identified in microregions of the Rio Grande do Sul state and in the city of Tubarão, Santa Catarina state. In conclusion, the studies assessed showed a wide variation in hypertension control rates. It is worth noting that the comparison between studies was a major limiting factor, because of the different methods used.

Arterial hypertension and associated factors in patients submitted to myocardial revascularization

“…Although a Brazilian study on its prevalence is not available, about 30% of the Brazilian adult population is estimated to be hypertensive, and this rate is doubled in the elderly (5) . Treatment in the pharmacological and nonpharmacological modalities was shown to be effective, but control of arterial hypertension is hardly satisfactory (6) . Sustained high pressure levels cause damage in target organs, with serious complications such as myocardial infarction, stroke, and kidney failure.…”

Chronic and asymptomatic diseases influence the control of hypertension treatment in primary care

“…More than half (60%) of the studied hypertensive patients had controlled blood pressure, slightly higher rates when compared to other national studies (4,(17)(18)(19) . Among the bio-social characteristics of hypertensive patients that were associated with the control, the fact that women are more controlled also coincides with the results of other studies (20)(21)(22) .…”

“…Despite the proven efficacy of pharmacological and non-pharmacological measures in the treatment of hypertension, poor control of blood pressure is still very frequent. A review study evaluated that the control of hypertension in Brazilian in publications showed control rates below 50% in most of them, except for two studies that showed rates of 52.4% and 57.6% (4) . We highlight that, in the context of chronic diseases, the control of blood pressure is directly related to adherence to treatment.…”

Hipertensos com e sem doença renal: avaliação de fatores de risco

“…In recent years, population-based studies in Brazil have shown blood pressure control rates ranging between 30% and 50% (24) . However, the control of blood pressure can be more compromised in the presence of comorbidities and end organ damage.…”
