Abstract
Background. Fibrinogen elevation is associated with a worse prognosis in patients with acute coronary syndrome (ACS). The aim of the present study was to assess the prognostic value of increased fibrinogen concentrations in ST-elevation myocardial infarction (STEMI) patients treated with primary percutaneous coronary intervention (PCI). Methods. A total of 428 STEMI patients treated with primary PCI were retrospectively selected (median age: 62 years; 82.5% males) from a continuous case series of 832 ACS patients. Plasma fibrinogen concentrations were measured before PCI and after 24, 48, and 72 hours. In the 4-year follow-up, one major adverse cardiovascular event (MACE) occurred in 111 patients (40%): 17 re-STEMI (7%), 64 re-PCI (22%), 22 cardiac deaths (7%), and eight non ST-elevated acute coronary syndromes (NSTEACS, 4%). Results. According to the reference change value, fibrinogen concentrations increased in 25% of patients at 24 h, 64% at 48 h and 19% at 72 h. Only fibrinogen concentrations at 48 h showed a mild association with overall MACEs (p = 0.036): the risk increased, starting from a concentration of 4 g/L. However a further multivariate model did not confirm any prognostic value. No association with specific MACEs emerged. Conclusions. In contrast to NSTEACS patients, fibrinogen concentrations increased slightly in STEMI patients after primary PCI, however, they were not as prognostic as for MACEs.
