[Use of the CHADS2 score as a predictor of the risk of mortality in hypertensive patients. The FAPRES study]

Abstract

Foundations and aim: The aim of this study is to analyze the CHADS2 score as a marker of the risk of mortality in hypertensive patients, with and without the presence of atrial fibrillation.

Methods: We included 1,003 hypertensive patients≥65 years. Risk factors, and CHADS2 score were recorded among other factors, as well as clinical follow-up of number and type of deaths.

Results: Mean age was 72.8±5.8 years, and 47.5% were men. During follow-up there were 41 deaths, 20 were of cardiovascular origin. Patients with higher CHADS2 had a higher mortality: 1.5% CHADS2=1; 4.7% in CHADS2=2; 9.1% in CHADS2=3, and 7.8% in CHADS2≥4.

Conclusions: The CHADS2 score can be a clinical instrument of easy application to identify hypertensive patients with a high risk of mortality.
