Long-term prognosis after a minor stroke: 10-year mortality and major stroke recurrence rates in a hospital-based cohort

Stroke; a Journal of Cerebral Circulation

Abstract

Determinants of long-term outcome are not well defined in minor stroke patients. This study aims to evaluate which factors are independent long-term predictors of death and major stroke recurrence in a cohort of minor ischemic strokes. A cohort of 322 patients with first-ever minor ischemic strokes (mean age, 55 years; 89% were treated with antiplatelet or anticoagulant drugs) with minor (Rankin score=2) or no disability (Rankin score <2) were followed for 10 years, with only 6% lost to follow-up. Death and major stroke recurrence rates were evaluated by Kaplan-Meier analysis. Hazard ratios and 95% confidence intervals (CI) of factors with P<.1 at the log-rank test were evaluated by multivariate Cox analysis. The 10-year mortality rate was 32%, with a relative risk of 1.7 (95% CI, 1.4 to 2.1) compared with the age- and sex-matched general population. The 10-year recurrence rate of major strokes was 14%. The hazard ratio (95% CI) of death was 1.1 (1.05 to 1.09) for age (1-year increments), 3.4 (2.2 to 5.2) for minor disability, 1.8 (1.1 to 3.1) for myocardial infarction (MI), 2.0 (1.1 to 3.7) for nonvalvular atrial fibrillation, and 1.8 (1.2 to 2.7) for hypercholesterolemia. The hazard ratio (95% CI) of major stroke recurrence w...Continue Reading

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Brain Ischemia

Brain ischemia is a condition in which there is insufficient blood flow to the brain to meet metabolic demand. Discover the latest research on brain ischemia here.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
