Objective: To establish the frequency of subtypes of ischemic stroke according to Bamford classification and to determine the associated risk factors.
Material & Methods: This was a cross-sectional study conducted at the Stroke Unit of Rehman Medical Institute (RMI) Peshawar from January 2019 to June 2019. All patients admitted in the Stroke unit with acute ischemic stroke were included after taking informed consent. Their stroke subtype and factors associated with stroke were noted. For age, mean±SD were calculated and for gender, stroke territory, HTN, DM, AF, IHD, and dyslipidemia, frequencies and percentages were calculated. Data was collected on a pre-designed pro forma and analyzed using SPSS version 22.
Results: Ninety-three patients were included. 55.9% (n=52) were males. Mean age was 63.77±12.5 years. Majority patients 45.2%, n=42 had Partial Anterior Circulation Stroke (PACS) followed by Total Anterior Circulation Stroke (TACS) that was seen in 25.8%, n=24 patients. Posterior Circulation Stroke (POCS), Multi territory and Lacunar Stroke (LACS) were observed in 15.1 %( n=14), 10.8% (n=10) and 3.2% (n=3) patients respectively. Hypertension (HTN) was the most common associated risk factor that was seen in 79.6% patients followed by Diabetes mellitus (DM) that was present in 49.5% (n=46) and structural heart disease was the third most common risk factor affecting 36.6%(n=34) of our study population. About 29% (n=27) had Ischemic heart disease (IHD) and 23.7% had dyslipidemia. Atrial fibrillation (AF) was observed in 18.7% (n=17), while 8.6% (n=8) of our study populations were tobacco smoker.
