    Abstract:
    AIMS: To evaluate the predictive value of high sensitivity (hs) C-reactive protein levels on long-term survival in patients with ST-elevation myocardial infarction (STEMI) treated with primary PCI. METHODS AND RESULTS: We conducted a retrospective analysis of 758 STEMI patients (from January 2003 to December 2005), with STEMI onset <12 h and hs-C-reactive protein determination on admission. Patients were classified into four groups [I (hs-C-reactive protein < 0.48 mg/dL), II (hs-C-reactive protein > or = 0.48 to <1.2 mg/dL), III (hs-C-reactive protein > or = 1.2 to <3.1 mg/dL), IV (hs-C-reactive protein > or = 3.1 mg/dL)] according to quartiles of hs-C-reactive protein serum level. The IV quartile hs-C-reactive protein group had a higher incidence of in-hospital mortality and cumulative adverse events. At a mean follow-up of 724 +/- 376 days (range 0-1393), the IV quartile hs-C-reactive protein group showed lower estimated survival, lower estimated myocardial infarction-free survival and lower estimated event-free survival. At multivariable analysis hs-C-reactive protein appeared to be an independent predictor of long-term mortality (HR: 1.04, 95% CI: 1.01-1.07, P = 0.003), long-term mortality and re-infarction (HR: 1.03, 95% CI: 1.01-1.06, P = 0.008) and adverse events (HR: 1.03, 95% CI: 1.01-1.05, P = 0.03). CONCLUSION: Evaluation of hs-C-reactive protein on admission in STEMI patients undergoing primary PCI allows reliable risk stratification of these patients.
