| Popis: | Objective The purpose of this study was to clarify the clinical features of ischemic patients for whom cigarette smoking was the sole risk factor for ischemic stroke. Methods Among the 1,329 patients (male, n=833; female, n=496) with acute ischemic stroke who were admitted to our hospital between April 2005 and September 2016, 346 (26%) were smokers [male, n=308 (36.9%); female, 38 (7.6%)]. In 42 (3.1%; male, n=41; female, n=1) cases, cigarette smoking was considered to be the sole risk factor for ischemic stroke. Data regarding gender, age, the clinical type of ischemic stroke, the National Institutes of Health Stroke Scale (NIHSS) score at the admission, the modified Rankin scale (mRS) scores before the onset and at discharge, the progression of symptoms, and the recurrence of infarction were investigated. Results The mean age of the 42 patients was 63.2±12.4 years (range, 26-86 years). The clinical types of ischemic stroke included atherothrombosis (n=19), lacunar (n=17), other type (n=2) and undetermined type (n=4). The median NIHSS score at the time of admission for ischemic stroke was 2 (interquartile range: IQR 1-4.25). The median mRS scores before the onset and at the discharge were 0 (IQR 0-0) and 1 (IQR 0-2), respectively. One patient had symptoms of progression; no patients had recurrence of infarction. Conclusion Our findings suggest that cigarette smoking alone may induce ischemic stroke; moreover, patients for whom smoking was the sole risk factor for ischemic stroke showed milder symptoms in comparison to patients with other risk factors; however, ischemic stroke was induced from youth. Since cigarette smoking has detrimental effects on the central nervous system, we suggest that people be encouraged to quit smoking in order to maintain good health. |
