Background and Purpose: Stroke is the second cause of mortality and the leading cause of disability. Using the clinical scale to predict the outcome of the patient play an important role in clinical practice. The Totaled Health Risks in Vascular Events (THRIVE) score has shown broad utility, allowing prediction of clinical outcome and death. Methods: A cross-sectional study conducting on 102 patients with acute ischemic stroke using THRIVE score. The outcome of patient was assessed by mRankin in the day of 30 after stroke. Statistic analysis using SPSS 15.0. Results: There was 60.4% patient in the group with THRIVE score 0 – 2 points having a good outcome (mRS 0 - 2), patient group with THRIVE score 6 - 9 having a high rate of bad outcome and mortality. Having a positive correlation between THRIVE score on admission and mRankin score at the day 30 after stroke with r = 0.712. THRIVE score strongly predicts clinical outcome with ROC-AUC was 0.814 (95% CI 0.735 - 0.893, p<0.001), Se 69%, Sp 84% and the cut-off was 2. THRIVE score strongly predicts mortality with ROC-AUC was 0.856 (95% CI 0.756 - 0.956, p<0.01), Se 86%, Sp 77% and the cut-off was 3. Analysis of prognostic factors by multivariate regression models showed that THRIVE score was only independent prognostic factor for the outcome of post stroke patients. Conclusions: The THRIVE score is a simple-to-use tool to predict clinical outcome, mortality in patients with ischemic stroke. Despite its simplicity, the THRIVE score performs better than several other outcome prediction tools. Key words: Ischemic stroke, THRIVE, prognosis, outcome, mortality

Background: Stroke is a disabling condition that has physical and mental impact on a patient’s life. Stroke is an important morbidity for low and middle income countries like Nepal. Hypertension, diabetes, smoking, and dyslipidemia are common risk factors in this regard and are inadequately controlled; mainly because of poor public awareness, inadequate infrastructure, lack of service and qualified manpower.Objectives: This study aims to provide insight into the epidemiology and risk factors in ischemic stroke patients.Methodology: A descriptive cross sectional study was conducted in 92 ischemic stroke patients at a tertiary care hospital Kathmandu Medical College and Teaching Hospital (KMCTH), Sinamangal, Nepal from December 2017 to June 2018. Consecutive sampling technique was used and data was collected from ischemic stroke patients above 14 years of age who were admitted in the Department of Neurology. Information regarding pre-morbid and morbid conditions, imaging findings as well as results was obtained from biochemical analysis of blood after taking consent from the patient or patient’s relative. Statistical Package for the Social Sciences Version 20 was used as a tool for statistical analysis.Results: Their mean age was 63.25 years with standard deviation of 16.45. Dyslipidemia was the most commonly found risk factor which was present in 77.2% of the subjects, followed by smoking (59.8%), presence of carotid artery atherosclerosis (59.8%), hypertension (50%), atrial fibrillation (26.1%) and diabetes mellitus(15.2%). Smoking was significant in males and heart disease was mostly seen in females.Conclusion: Dyslipidemia and smoking were the most common risk factors followed by carotid artery atherosclerosis. Patients with hypertension and dyslipidemia had higher incidence of stroke in both young and elderly group.

Introduction: Stroke is the second leading cause of mortality worldwide. Ischemic stroke is  more prevalent than hemorrhagic stroke and atherosclerosis is the major cause of ischemic stroke. The increased carotid artery intima-media thickness (CIMT) is considered to be useful indicator of early atherosclerosis. So, this study was aimed to correlate the relationship between atherosclerotic risk factors and intima-media thickness of carotid artery in patients with acute ischemic stroke. Material and Methods: In this cross-sectional study, 100 consecutive patients of acute ischemic stroke and 50 healthy relatives of patients as control were studied for presence of atherosclerotic risk factors and carotid artery intima?media thickness by B-mode Doppler ultrasonography.Results: In this age and sex matched study, higher CIMT measurement was found among patients of acute ischemic stroke than healthy controls (0.849 ± 0.196 vs 0.602 ± 0.092; p < 0.001). The CIMT was well correlated with smoking (Beta = 0.295; t = 5.728; 95% CI 0.088 to 0.181; p < 0.001); hypertension (Beta = 0.387; t = 6.518; CI 0.112 to 0.209; p < 0.001); di abetes (Beta = 0.237; t = 4.848; CI 0.074 to 0.175; p < 0.001); hypercholesterolemia (Beta = 0.292; t = 5.840; CI 0.096 to 0.195; p < 0.001), but not with age (p = 0.153). The CIMT was also found to be higher among acute ischemic stroke patients who were smoker, hypertensive, diabetic and hypercholesterolemic than non?smoker, normotensive, non-diabetic and normo-cholesterolemic respectively. Conclusion: The CIMT being indicator of atherosclerosis can be used as future predictor of ischemic stroke.
