Stroke in young adults is an important cause of lifelong morbidity. The aim of this study was to explore some possible admission indicator of subsequent lacunar or non-lacunar strokes. We enrolled 626 patients with the first young cerebral strokes and divided them into lacunar and non-lacunar stroke based on clinical presentation and neuroradiological findings; and the analyses were adjusted for the effects of potential confounders. Hypertension, hyperlipidemia, atrial fibrillation, cerebral vascular moyamoya malformation were significantly more frequent in non-lacunar patients than lacunar patients (respectively P=0.005, 0.048, 0.000, 0.015, 0.030). Serum BUN, Triglyceride, Cholesterol, HDL, UA, White cell count, Fibrinogen, INR and bilirubin (including Total bilirubin, Direct bilirubin, Indirect bilirubin) levels on admission were higher in non-lacunar strokes than in lacunar strokes. Serum white blood cell count (Odds Ratio 1.097; 95% Confidence Interval 1.006-1.195, P=0.035), lower high-density lipoprotein levels (defined as HDL<0.9 mmol/L) (Odds Ratio 1.884; 95% Confidence Interval 1.035-3.285, P=0.038) and serum total bilirubin (Odds Ratio 1.054; 95% Confidence Interval 1.019-1.091, P=0.003) were associated with increased risk for non-lacunar stroke, whereas lacunar stroke was related to age at onset (Odds Ratio 0.929; 95% Confidence Interval 0.888-0.972, P=0.001) and SUA (Odds Ratio 0.997; 95% Confidence Interval 0.995-0.999, P=0.015). The excess risks were blood WBC, lower HDL and total bilirubin levels for non-lacunar strokes, and serum UA and age at onset for lacunar strokes in young Chinese patients.
