COMPARISON OF ACUTE ISCHEMIC STROKE FUNCTIONAL OUTCOME IN SMOKERS AND NONSMOKERS MEASURED BY CANADIAN NEUROLOGICAL SCALE (CNS) AND NIHSS

Abstract

Background. Stroke is the world’s second leading cause of death and main cause of disability. Smoking is a well-known risk factor of stroke. However, the correlation between smoking and stroke outcome is still remains a controversy. Objective. To analyze the differences of functional outcome between smokers and non-smokers in acute ischemic stroke patients. Methods. The design used in this study is retrospective cross-sectional. The functional outcomes of acute ischemic stroke were measured by Canadian Neurologic Scale (CNS) and NIHSS over a period of seven days after the onset of stroke. Differences of CNS and NIHSS were analyzed using Mann-Whitney U test. Results. Median of CNS in smokers and non-smokers were 9.0 and 11.0, respectively. Median of NIHSS in smokers and non-smokers were 4.0 and 2.0, respectively. There were no significant differences in the analysis of CNS score between smokers and non-smokers and NIHSS score analysis between smokers and non-smokers. Conclusion. Smoking is not correlated with the functional outcome in acute ischemic stroke patients measured by CNS and NIHSS.
