Hipertensão arterial sistêmica e fatores associados em uma coorte de pacientes portadores de doenças cardiovasculares e cerebrovasculares

Abstract

The aim of this seccional study nested with the Cohort of Patient Carrier of Cardiovascular and cerebrovascular disease was to determine the prevalence of systemic hypertension (HAS) and to check the association with different factors between the 370 adults interviewed of 2009 and 2010, entered in the Vascular Medicine Institute of Mãe de Deus Hospital. The achievement of this study was bound the execution of the baseline field collect of Cohot. Initially had a expectation of entrance of approximately 480 patient in one year. With a lower entrance, some association measures were not possible in this moment. Were descreptive analyzis of frequency, with caracterization of the study population, applying the tests of chi-square e linear association of Pearson. Were analyzed the prevalence ratio employing the robust Poisson regression. The variables were analyzed in three hierarchical levels, being the comorbidity entered individually for control of collinearity effect. Between the study sujects, the prevalence of HAS was 45,1%, (CI95%: 43,5-46,7). Observed greater prevalence of HAS in woman (RP=1,26, IC95%: 1,00-1,59), in sujects with chart register of stroke (AVC) (RP=1,36, IC95%: 1,08-1,71), of diabetes mellitus (RP=1,26, IC95%: 1,00-1,60) and between the carrier others comorbidities (RP=4,13, IC95%: 2,54-6,72 for one and RP=5,47, IC95%: 3,41-8,77 for two or more). In the sujects with char register of acute myocardial infarction (IAM), the prevalence of HAS was lower (RP=0,69, IC95%: 0,53-0,91). After akept association with HAS the variable of sex, AVC, IAM, diabetes mellitus and to have one or more comobidities. In this study the prevalence of 8 comorbidity presented like a factor that may contribute for the greater prevalence of HAS, is important the determine the risk factors and the suggestion of actions of care for the most effective compliance of treatment and blood pressure levels control.
