FROMETA GUERRA, Adonis et al. Risk factors of hypertensive acute cerebrovascular disease. Rev haban cienc méd [online]. 2010, vol.9, n.4, pp. 534-544. ISSN 1729-519X.

A case-control study was carried out in patients admitted with a clinical diagnosis of acute cerebrovascular disease in the municipalities of Escuque, Valera and Sábana Libre, State of Trujillo, Venezuela, from January 1st, 2003 to December 31st, 2004, with the objective of identifying risk factors for the occurrence of this condition. The sample was selected at random and included 140 cases and 140 controls. The variables studied were age, sex, past history of cerebrovascular disease, toxic habits, heart disease, arterial hypertension, diabetes mellitus and obesity. A data base was created in SPSS 11.1. Variable associations were measured using odds ratio and a logistic regression analysis was performed. An univariate analysis showed that the factors studied were risk factors for the occurrence of acute cerebrovascular disease, while a multivariate analysis demonstrated that the most important independent factor was hypercholesterolemia with a sevenfold risk of occurrence of the condition (OR: 7,19; CI: 3,075-16,837; p: 0,000), followed by arterial hypertension (OR: 4,23; CI: 1,978-9,064; p: 0,000), diabetes mellitus (OR: 3,19; CI: 1,139-8,98; p: 0,027), and finally past history of heart disease (OR: 1,90; CI: 1,413-1,978; p: 0,031). It was concluded that the values obtained by adjustment of the logistic regression function for independent risk factors allow to estimate the risk of suffering from this disease.
