[BDSP. Notice produite par INIST-CNRS WdozR0x4. Diffusion soumise à autorisation]. Stroke occurs particularly frequently in elderly people and, being more often disabling than fatal, entails a high social burden. The predictors of stroke mortality have been identified in 3282 subjects aged>=65 years, taking part in the CArdiovascular STudy in the ELderly (CASTEL), a population-based study performed in Northeast Italy. Historical and clinical data, blood tests and 14-year fatal events were recorded. Continuous items were divided into quintiles and, for each quintile, adjusted relative risk (RR) with 95% confidence intervals [CI] was derived from multivariate Cox analysis. Age, historical stroke (RR : 5.2 ; 95% CI : 3.18-8.6) and coronary artery disease (RR : 1.38 ; CI : 1.18-2.1), atrial fibrillation (RR : 2.40 ; CI : 1.42-4.0), arterial hypertension (RR : 1.33 ; CI : 1.15-1.76), systolic blood pressure>=163 mmHg (RR : 1.84 ; CI : 1.20-2.59), pulse pressure>=74 mmHg (RR : 1.50 ; CI : 1.13-2.40), cigarette smoking (RR : 1.60 ; CI : 1.03-2.47), electrocardiographic left ventricular hypertrophy (RR : 1.72 ; CI : 1.10-2.61), impaired glucose tolerance (IGT, RR : 1.83 ; CI : 1.10-3.0), uric acid (UA)>0.38 mmol/l (RR : 1.61 ; CI : 1.14-2.10), serum potassium>=5 mEq/l (RR : 1.70 ; CI : 1.24-2.50) and serum sodium
