Comparative Study on outcome for Anterior versus Posterior circulation Stroke
Abstract: Introduction: Among the non - communicable diseases, stroke is the second leading cause of mortality and third leading cause of disability worldwide Therefore, it is important to understand the risk factors and outcomes of stroke and its subtypes to improve the quality of care. Aims and objectives: The intention of this study is to clinically compare the two types of stroke patients admitted in KGMCH based on the NIHSS score and mRS as well as prediction of prognosis based on the result of these two scales. Materials and methods: An observational cross ? sectional study was conducted by Department of Neurology, KGMC for period of 1year (March2021to March2022). 140 patients of acute is chemicstroke were included in the study. Samples were collected by systematic random sampling. The two types of strokes are compared on the basis of severity and NIHSS score. The clinical features, outcome and prognosis between anterior and posterior circulation stroke group are compared and results are analyzed. Results: In anterior circulation, hypertension was seen in 73 (91.3%) enrolled patients. In posterior circulation, hypertension was seen in 54 (90.0%) enrolled patients. Association of type of stroke vs hypertension was statistically not significant (p = 0.8008). In anterior circulation, diabetes mellitus was seen in 51 (63.8%) enrolled patients. In posterior circulation, diabetes mellitus was seen in 37 (61.7%) enrolled patients. Association of type of stroke vs diabetes mellitus was statistically not significant (p = 0.8006). In case of anterior circulation, the mean of NIHSS score on day 0 (mean ? SD) of the enrolled patients was 13.9875 ? 4.0362. In posterior circulation, the mean of NIHSS score on day 0 (mean ? SD) of the enrolled patients was 23.8833 ? 4.5737. Difference of mean NIHSS score on day 0 vs type of stroke was seen to be statistically significant (p<0.0001). In anterior circulation, the mean of mRS score (mean ? SD) of enrolled patients on day 5 was 2.1125 ? 0.9936. In posterior circulation, the mean of mRS score (mean ? SD) of enrolled patients on day5 was 4.6333 ? 0.8227. The difference of mean mRS score on day 5 vs type of stroke was found to be statistically significant (p<0.0001). Conclusion: Posterior circulation stroke was found to be associated with poorer outcomes compared to anterior circulation stroke. This is supported by higher NIHSS and mRS scores which indicates worse prognosis.
