Abstract
- Aim: To determine the mortality, degree of dependence, survival, and years of life lost (YLL) after first episode of stroke.<br />Design: Cohort study.<br />Location: Community based register.<br />Participants: A total of 553 subjects between 15-90 years with a first episode of definitive or transitory stroke were recruited between 01/04/2006 and 31/03/2008.<br />Measurements: The analyses were performed with the use of time-to-event methods, according to the intention-to-treat principle. The level of dependency was assessed according to the Barthel Scale one year after stroke; YLL (1-70 years) from the mean life expectancies at birth; survival analysis by Kaplan-Meier's curves, bivariate analysis comparing the variables between patients who had survived and those who died, and Cox's multivariate.<br />Results: The mean age was 73.3 (±11.6 years. The mean time of follow-up was 29.7 ± 13,4 months, during which 26.6% of the patients died. The mean Barthel score fell by >20%, particularly among women. There was moderate or greater dependence in 41.5% (95%CI 30.6-52.8%) of the subjects. The overall accumulative probability of survival was 0.96 (95% CI 0.94-0.97) in the first month and 0.69 (95% CI 0.65-0.72) in the fourth year. The thrombolytic treatment showed a protective effect on mortality, particularly among the women. The main predictive variables were, history of recurrent cardiovascular event (RR 6.7, 95% CI 2.2-21.7) and aging (RR 1.08, 95% CI 1.01-1.2). The average YLL was 11.5/10000/year SD7.2, and higher among men.<br />Conclusion: There are differences in functional outcome, mortality, and potential years of life lost by gender. A new cardiovascular event is an independent prognostic factor of survival.<br /> (Copyright © 2011 Elsevier España, S.L. All rights reserved.)
