Relationship Between Plasma Fibrinogen Level and Ischemic Stroke in Patients with Nonvalvular Atrial Fibrillation / 国际脑血管病杂志

ABSTRACT

Objective:To investigate whether the increased plasma fibrinogen level is an independent predictor of cardiogenic embolism in patients with nonvalvular atrial fibrillation (NVAF).Methods:Ninety-eight patients with NVAF hospitalized for cardiac causes were evaluated,and 24 of them had a history of ischemic stroke.The relationship between fasting plasma fibrinogen level and ischemic stroke were analyzed.Results:After adjusting traditional cardiovascular risk factors.the patients with NVAF who had the history of ischemic stroke were significantly older than those without(mean [SD] age 73.6 [8.4]vs.69.1[10.3] years,P=0.017).1he prevalence of hypertension was significantly higher(83.3%va.66.2%,P=0.011).The proportion of patients with left ventricular systolic dysfunction was significantly higher(63.1% vs.45.9%,P=0.006),and plasma fibrinogen level increased significantly (mean [SD] 365 [108]vs.312[82] mg/dL,P=0.008).Conclusions:Plasma fibrinogen level is independently associated with a history of ischemic stroke in older patients with NVAF hospitalized for cardiac causes.
