BACKGROUND: Inflammatory process plays an important role in the pathogenesis of acute coronary syndromes.
HYPOTHESIS: The study was undertaken to evaluate whether admission levels of C-reactive protein (CRP), fibrinogen, interleukin-6 (IL-6). and macrophage colony stimulating factor (MCSF) can predict short-term prognosis in patients with unstable angina.
METHODS: C-reactive protein, fibrinogen, IL-6, and MCSF were measured on admission in 141 consecutive patients, aged 59 +/- 10 years, with unstable angina (Braunwald class IIIb). Patients were divided into two groups according to their in-hospital outcome: Group 1 comprised 77 patients with a complicated course (2 died, 15 developed nonfatal myocardial infarction, and 60 had recurrence of angina), and Group 2 comprised 64 patients with an uneventful course.
RESULTS: Admission median levels of CRP (8.8 vs. 3.1 mg/l, p = 0.0002). fibrinogen (392 vs. 340 mg/dl, p = 0.008), IL-6 (8.8 vs. 4.5 pg/ml, p = 0.03), and MCSF (434 vs. 307 pg/ml, p = 0.0001) were higher in Group I than in Group 2. The MCSF levels were an independent risk factor for in-hospital events, with an adjusted odds ratio for eventful in-hospital outcome of 3.3 (95% confidence interval 1-10.9, p = 0.04), and correlated with levels of IL-6 (r(s) = 0.52, p = 0.0001), CRP (r(s) = 0.43, p = 0.0001), and fibrinogen (r(s) = 0.25, p = 0.004).
CONCLUSIONS: These findings suggest that among the studied inflammatory indices only increased admission levels of MCSF are strongly and independently related with adverse short-term prognosis in patients with severe unstable angina.
