Abstract
ABSTRACT Objectives Alcohol consumption is a risk factor for stroke. However, there are no available data on the effect of alcohol consumption on the long-term outcome of ischemic stroke in China. Therefore, this study aimed to explore the association of alcohol consumption with the prognosis of ischemic stroke by subtype in different follow-up periods after stroke. Methods This 12-month follow-up study recruited 3830 acute ischemic stroke patients from Tianjin, China, between 2016 and 2018. Patients were categorized into two groups according to their consumption of alcohol. Differences in mortality, recurrence, and dependency rates at 3 and 12 months after stroke were compared between both groups. Results The mortality, recurrence, and dependency rates at 12 months after stroke were significantly higher in patients who previously consumed alcohol than in those without previous alcohol consumption (all P < 0.005). A similar trend was observed for mortality rate at 3 months after stroke (P < 0.001). The risk of death at 3 months after an atherothrombotic stroke decreased by 63.4% (relative risk [RR], 0.366; 95% confidence interval [CI], 0.144–0.935) among patients who previously consumed alcohol compared with those who never consumed alcohol. Moreover, for patients with small artery disease classified according to the Trial of ORG 10,172 in Acute Stroke Treatment (TOAST), the recurrence and dependency rates at 12 months after stroke decreased by 49.2% (RR, 0.508; 95% CI, 0.259–0.996) and 49.5% (RR, 0.505; 95% CI, 0.258–0.990), respectively, among patients who consumed alcohol. Conclusions Previous alcohol consumption decreased the risk of death at 3 months after stroke among patients with atherothrombotic stroke according to the TOAST classification. Furthermore, for patients with small artery disease (according to TOAST classification), alcohol consumption significantly decreased the risk of recurrence and dependency at 12 months after stroke. This study highlights an urgent need to quantify the association of alcohol consumption with outcomes after stroke in China to improve stroke prognosis.
