Usefulness of Preprocedure High-Sensitivity C-Reactive Protein to Predict Death, Recurrent Myocardial Infarction, and Stent Thrombosis According to Stent Type in Patients With ST-Segment Elevation Myocardial Infarction Randomized to Bare Metal or Drug-Eluting Stenting During Primary Percutaneous Coronary Intervention.

摘要

It is unknown whether high-sensitivity C-reactive protein (hs-CRP) predicts outcome depending on implanted stent type. We investigated the prognostic value of hs-CRP in relation to type of stent implanted in patients with ST-segment elevation myocardial infarction (STEMI). Immediately before primary percutaneous coronary intervention (pPCI), 301 patients had blood drawn. Patients were categorized according to hs-CRP levels and combination of hs-CRP (2 mg/L) and stent type (bare metal stent [BMS] vs drug-eluting stent [DES]). Hs-CRP >2 mg/L (median, hazard ratio 2.7, 95% confidence interval 1.3 to 5.6, p = 0.007) and the combined variable of hs-CRP >2 mg/L and BMS (hazard ratio 2.4, 95% confidence interval 1.2 to 4.5, p = 0.006) independently predicted the composite end point of death and MI at 36-month follow-up. There was a significant interaction (p = 0.006) for hs-CRP and stent type. Survival analysis demonstrated significant differences for occurrence of death and MI: 4.8% in BMS + CRP 2 mg/L, and 27.9% in BMS + CRP >2 mg/L. None of the 14 stent thromboses occurred in patients with BMS + CRP 2 mg/L to decrease long-term adverse outcomes including stent thrombosis in patients with STEMI treated with pPCI. These findings need confirmation in larger randomized clinical trials.
