Role of CHA

Introduction: Acute ischemic stroke (AIS) is a major cause of hospital admission and is responsible for a large proportion of disabilities. The CHA Methods: A cross-sectional study was conducted in a tertiary center in Nepal for the period of 12 months (June 2021 to June 2022) including patients more than 18 years presenting with symptoms of stroke and underwent neuroimaging studies at admission with the diagnosis of acute ischemic stroke. The National Institute of Health (NIH) stroke scale score, pre-stroke and current functional status according to modified Rankin scale (mRS) score were noted. The CHA Results: Seventy-five patients with acute ischemic stroke were enrolled in the study, in which 48 (64%) were male and only 35 (46.7%) of patients could reach the emergency department within 24 hours of onset of symptoms. The mean age of patients was 61.8 ± 16.04 years and 18 (24%) of patients were of age ≥75 years. Hemiplegia/paresis with UMN facial palsy was the most common presentation. Smoking and hypertension were the most common risk factors followed by diabetes mellitus. The severity of stroke as evaluated by NIH stroke scale score at the time of admission categorized as minor, moderate, moderately severe, and severe stroke was present in 7 (9.3%), 47 (62.7%), 11 (14.7%), and 10 (13.3%) patients, respectively. Low-risk CHA Conclusion: The CHA
