Background: Acute coronary syndromes (ACSs) are the primary cause of mortality worldwide. The aim of the study was to assess the as‑ sociations of serum fibrinogen and plasma D‑dimer levels with angiographic severity of atherosclerotic lesions as well as the presence of in‑hospital complications and complications at 30‑day follow‑up in patients with ACS. Methods: This was a prospective study including 107 patients with ACS. Severity of CAD was assessed by the Gensini score. Correlations of D‑dimer and fibrinogen levels with complica‑ tions such as heart failure, arrhythmia, recurrent angina, and cardiac death were assessed using the Pearson correlation coefficient and the receiver operating characteristic curve analysis. Results: The mean age of patients was 61±10.9 years. Mean serum fibrinogen levels were higher in individuals with severe left ventricular (LV) dysfunction than in those with moderate and mild LV dysfunction (444 mg/dl, 404 mg/dl, and 330 mg/dl, respectively). Similarly, the mean plasma D‑dimer level was higher in individuals with severe ACS (1.03 µg/ml) than in those with moderate (1.88 µg/ml) and mild ACS (3.5 µg/ml). Conclusion: Our study revealed that patients with higher serum fibrinogen levels tend to have more severe ACS, greater LV dysfunction, and a higher rate of complications. Therapies aimed at reducing fibrinogen levels might help reduce mortality and morbidity in patients with ACS. JRCD 2019; 4 (5): XX–XX
