INTRODUCTION: Elevated clotting factors and thrombin generation have been reported to occur in patients with heart failure (HF). Circulating activated factor XI (FXIa) and active tissue factor (TF) can be detected in acute coronary syndromes and stable angina. OBJECTIVES: We investigated circulating FXIa and active TF and their associations in patients with systolic HF due to ischemic cardiomyopathy. PATIENTS AND METHODS: In an observational study, we assessed 53 consecutive patients, aged below 75 years, with stable HF associated with documented coronary artery disease (CAD). Atrial fibrillation, recent thromboembolic events, and current anticoagulant therapy were the exclusion criteria. Plasma TF and FXIa activity was determined in clotting assays by measuring the response to inhibitory monoclonal antibodies. RESULTS: Coagulant TF activity was detected in 20 patients (37.7%), and FXIa in 22 patients (41.5%). Patients with detectable TF activity and/or FXIa were younger, had a history of myocardial infarction more frequently, significantly higher F1+2 prothrombin fragments, larger left atrium (LA) and right ventricular diastolic diameter, and higher right ventricular systolic pressure than the remaining subjects (P ≤ 0.01 for all). Circulating FXIa was positively correlated with F1+2 levels (r = 0.69; P < 0.001). CONCLUSIONS: Circulating active TF and FXIa occurred in about 40% of patients with systolic HF due to ischemic cardiomyopathy. The presence of these factors was associated with enhanced thrombin formation. Associations between both factors and LA diameter and right ventricular parameters might suggest that TF and FXIa predispose to thromboembolic complications of HF. |
