AbstractObjective: Small-vessel occlusions are the most common causes of mild strokes and, in China, account for approximately 27.3% of ischemic stroke cases. However, the factors associated with short- and long-term outcomes appear contradictory. Thus, we assessed the factors related to outcomes 3 years after small-vessel occlusion among patients aged 18 to 55 years.Methods: Between 2007 and 2014, we recruited patients who experienced small-vessel occlusion (according to Trial of Org 10,172 in Acute Stroke Treatment [TOAST] classification) aged 18 to 55 years and conducted a hospital-based follow-up study. The assessed outcomes were mortality, recurrence, and dependency within 3 years after the initial stroke. The outcome determinants were assessed using a multivariate logistic regression analysis.Results: A total of 276 patients (men, 76.09%) with small-vessel occlusions were enrolled in this study. In addition, 85.1% of the patients had strokes between the ages of 45 and 55 years. The risk of recurrence within 3 years was higher for patients who had moderate strokes than for those who had mild events (relative risk [RR], 3.09; 95% confidence interval [CI], 1.14-8.34; P < 0.05). Further, the risk of dependency within 3 years was 2.61 times higher in obese patients than in non-obese patients (RR, 2.61; 95% CI, 1.00-6.79; P < 0.05). The risks of recurrence and dependency within 3 years increased by 17% and 18%, respectively, for each 1-unit increase in fasting plasma glucose levels (RR, 1.17; 95% CI, 1.05-1.30 and RR, 1.18; 95% CI, 1.06-1.32, respectively; both P < 0.05).Conclusion: Our findings suggest that small-vessel occlusions cause the heaviest disease burden in patients aged 45 to 55 years. To reduce stroke recurrence, young and middle-aged patients with small-vessel occlusions should control their fasting plasma glucose levels and manage their weight.
