Background and Purpose-We investigated whether lacunar infarct (LI) patients with >1 lacune have different vascular risk factors, a different prognosis, and poorer functional outcome than those with a single lacune.Methods-The study included 175 first-ever LI patients. The group was divided according to the presence of multiple (n=136) or single (n=39) LI. The association of single or multiple LI with the principal vascular risk factors, leukoaraiosis, outcome, and recurrence was investigated with logistic regression models that included age, sex, and cardiac disease.Results-No significant differences were found between single and multiple LI with respect to age, hypertension, hyperlipidemia, smoking, and heavy alcohol drinking. Diabetes mellitus (odds ratio [OR], 2.43; 95% CI, 1.09 to 5.4), high levels of hematocrit (>0.47) (OR, 1.09; 95% CI, 1.04 to 1.21), and leukoaraiosis (OR, 3.58; 95% CI, 1.77 to 7.51) were significantly related to multiple but not to single LI. Stroke recurrence rate was 7.7% in patients with single LI and 24.3% in the multiple LI group (OR, 3.84; 95% CI, 1.1 to 13.3). During a median follow-up of 12 months (range, 6 to 156 months), 94% of the single LI patients and 77.2% of the multiple LI patients had favorable outcomes (Rankin Scale score 0 to 2) (OR, 5.4; 95% CI, 1.25 to 23.9).Conclusions-Diabetes mellitus, leukoaraiosis, and high levels of hematocrit are important risk factors in patients with >1 LI. The presence of multiple LI may be an important prognostic indicator not only for functional recovery but also for a higher rate of recurrence.
