Short Editorial: Clinical Characteristics of Resistant vs. Refractory Hypertension in a Population of Hypertensive Afro-descendants

Differences in the clinical behavior of arterial hypertension (AH) in diverse ethnic groups have long been the object of intense scientific investigation. The American Heart Association statistics for 2015 found that Afro-descendants have the highest prevalence of hypertension worldwide. In black, non-Hispanic men and women, the prevalence was 44.9% and 46.1%, respectively. Although such figures are not universal for all Afro-descendant populations, there are groups in which blood pressure levels are much higher, such as South-African blacks, in whom systolic blood pressure is 9.7 mmHg higher when compared to African-Americans.^,

Target-organ lesions and complications are more prevalent in Afro-descendants, when compared to Caucasians or Hispanics for the same pressure levels, in addition to the fact that they are more resistant to treatment.^,

Short Editorial: Hypertension in Special Populations: An Epidemiological Challenge

Rui Póvoa

Arterial hypertension (AH) is the most prevalent chronic disease worldwide and the main risk factor for most cardio-cerebrovascular diseases. The true prevalence in Brazil is still unknown, and the available data are from the Vigitel Study, where the information is obtained by telephone contact. The prevalence of hypertension in Brazil is estimated at around 31% in adult individuals. In recent data from the Vigitel Study, the prevalence was 25.7% of the adult Brazilian population. Knowledge of the real prevalence and geographic distribution is not only important for prevention and treatment measures, but also contribute to the knowledge of the genesis of the disease.

In some populations, particularly individuals of African descent, AH has its own characteristics, including prevalence, therapeutic response and severity.^, The multifactorial aspect of AH is only understood when assessing special populations considering their own habitats and habits, as in the case of quilombolas, where individuals with African ancestry still retain some genetic and cultural characteristics of the African origin. The analysis in this context is important, since we can detect aspects inherent to factors related to AH development.
