Background: Despite a significant advance in prevention and treatment of heart failure (HF), patients still struggle with decreased quality of life, high mortality, and recurrent hospitalizations. Several inflammatory cytokines have been widely investigated in the pathogenesis of HF.
Objectives: To investigate the prognostic value of fibrinogen on clinical outcomes of patients admitted with acute HF.
Methods: This retrospective study was based on data of patients hospitalized with acute HF. Demographics, laboratory, and clinical outcomes including length of stay and readmissions were obtained. We compared outcomes of patients with normal (< 430 mg/dl) and high (> 430 mg/dl) fibrinogen levels.
Results: We included 149 patients (mean age 67.6 ± 12.3 years, 73.8% male). In our cohort, 24 (16.1%) had normal fibrinogen (< 430 mg/dl) and 125 (83.9%) had high fibrinogen levels (> 430 mg/dl). Among patients with readmissions for HF, fibrinogen levels were higher (622 ± 136 vs. 470 ± 68, P < 0.001) and were associated with longer hospital stay. Fibrinogen remains an independent risk factor after adjusting to age, diabetes status, and left ventricular ejection fraction.
Conclusions: High fibrinogen levels may predict readmissions in patients with HF.
