Abstract
Fibrinogen is an independent risk factor for coronary events in population-based studies and inpatients with coronary heart disease, but there is an uncertainty about its prediction for stroke, particularly in secondary prevention. In view of this uncertainty, study was conducted to establish the role of serum fibrinogen in ischemic stroke. Fifty six patients with acute ischemic stroke of less than 7 days duration were recruited for the study. Fourty two age and sex matched candidates served as control. Baseline characteristics and blood pressure were recorded at admission to hospital. Computer tomography head was done in all patients as per protocol. Sampling took place in the early morning (7-9 AM) using all necessary precaution and serum fibrinogen was measured by method of Clauss. Statiscal analysis was performed using student t test and fisher exact test. In present study, mean plasma fibrinogen in patients group was 326.45 mg/dl, which was significantly higher than control group (202.23 mg/dl) (p<0.001). Mean plasma fibrinogen level in lacunar infarct and non-lacunar infarct did not differ significantly (307.47 mg/dl Vs. 333.19 mg/dl). Smoking was found to be a significant predictor of fibrinogen with 36.7% predictability whereas other parameters (risk factors for ischemic stroke) had little or no predictable value regarding serum fibrinogen. After adjustment for other possible ischemic stroke risk factors; plasma fibrinogen levels was found to be still significantly high in patients as compared to controls (p<0.001). Mean plasma fibrinogen level between patients who survived and who expired does not differ significantly. Present study concluded that fibrinogen is a powerful predictor of ischemic stroke though it does not predict the type and prognosis of stroke.
