Risks and causes of death in a community-based stroke population: 1 month and 3 years after stroke

We performed a community-based study on a cohort of 221 stroke patients followed for 3 years. In this paper, we tried to answer the following questions: Is the risk of dying increased throughout the first 3 years after stroke? What are the causes of death after the 1st month? What factors at stroke onset are independent predictors of early and late mortality? The relative risk of death was estimated using age- and sex-specific mortality rates for the Netherlands. Causes of death were registered by the attending physicians, mostly general practitioners. During the 1st month 26% of the patients died. At 1, 2 and 3 years, the cumulative mortality rates were 37, 46 and 54%, respectively. Stroke patients had an increased risk of dying, approximately twice that of the general population, during the 3 years of follow-up. In women, this increased risk was more pronounced than in men. After 1 month, cardiovascular pathology, stroke and diseases resulting from stroke were the causes of death in 70% of the patients, i.e. substantially higher than in the general population, matched for age and sex. Factors predicting mortality after stroke varied over time. Severity of the stroke, preexisting atrial fibrillation and congestive heart failure were associated with early mortality (within 30 days). For 1-month survivors, incontinence and preexisting atrial fibrillation were associated with mortality in the 1st year after stroke. After 1 year, only age was associated with mortality.
