© 2017, © The Author(s) 2017. The influence of raised fibrinogen levels on outcome in stable outpatients with peripheral arterial disease (PAD) has not been consistently investigated. We used data from the Factores de Riesgo y ENfermedad Arterial (FRENA) registry to compare ischemic events, major bleeding, and mortality in stable outpatients with PAD, according to their baseline plasma fibrinogen levels. Of 1363 outpatients with PAD recruited in FRENA, 558 (41%) had fibrinogen levels >450 mg/100 mL. Over 18 months, 43 patients presented with acute myocardial infarction, 37 had an ischemic stroke, 51 underwent limb amputation, 19 had major bleeding, and 90 died. Compared to patients with normal levels, those with raised fibrinogen levels had an over 2-fold higher rate of ischemic stroke (rate ratio [RR]: 2.30; 95% confidence interval [CI]: 1.19-4.59), limb amputation (RR: 2.58; 95% CI: 1.46-4.67), or death (RR: 2.27; 95% CI: 1.49-3.51) and an over 3-fold higher rate of major bleeding (RR: 3.90; 95% CI: 1.45-12.1). On multivariate analysis, patients with raised fibrinogen levels had an increased risk of developing subsequent ischemic events (hazard ratio [HR]: 1.61; 95% CI: 1.11-2.32) and major bleeding (HR: 3.42; 95% CI: 1.22-9.61). Stable outpatients with PAD and raised plasma fibrinogen levels had increased rates of subsequent ischemic events and major bleeding.
