arterial hypertension is the constant elevation of blood pressure figures with a polygenic and multifactorial origin. Hypertension is a disease of high incidence and prevalence worldwide. Objective: to demonstrate the familial aggregation for essential arterial hypertension and risk factors in affected individuals. Method: an observational, analytical, longitudinal and retrospective case / control investigation was carried out from the reference consultation for chronic non-communicable

By simple random sampling, the sample of 91 cases was obtained. The control group was formed at a ratio of 3:1 which included 273 individuals. Bioethical requirements were met. Inclusion / exclusion criteria were applied. The following statistics were used: Chi square, Odd Ratio (OR), including p and confidence interval. The variables were operationalized: age, sex, degree of consanguinity, and risk factors. The genealogical tree was obtained. Results: the age groups 56-65 years and 66 years and over, were the most affected. The male sex predominated (53.9 %). First and second-degree relatives of consanguinity showed the highest incidence of the disease. An association was found between the disease and its family history (X2 = 321.4) with an increased risk for relatives of the cases compared to the controls (OR = 10.93). The predominant risk factors were: smoking (OR = 2.18) and family history of disease (OR = 0.74). The association of risk factors with the disease was demonstrated (X2 = 176.9). Conclusions: essential arterial hypertension is a multifactorial, complex and polygenic disease with demonstrated familial aggregation.
