INTRODUCTION Implantation of bare metal or drug eluting stents supported by dual antiplatelet therapy (DAPT) is standard treatment for the management of patients with ST elevation myocardial infarction (STEMI). Individual response to aspirin and clopidogrel is heterogeneous, and decreased response is associated with thrombotic events following stenting. We postulated that systemic inflammation at the time of STEMI would diminish responsiveness to DAPT. The aim of this study is to evaluate the correlation between elevated high-sensitivity C-reactive protein (hs-CRP) as a marker of inflammation and decreased platelet sensitivity to DAPT in STEMI. METHODS We recruited patients with STEMI undergoing percutaneous coronary intervention (PCI) who received oral clopidogrel 600 mg loading dose followed by 75 mg daily maintenance dose and aspirin 325 mg daily. Platelet reactivity and hs-CRP were measured within 72 hours of PCI and at 6 weeks. For patients receiving eptifibatide, blood samples were taken 48 hours after discontinuation. Platelet reactivity was assessed using the VerifyNow platelet function analyzer. A cut-off value of 208 platelet reaction units (PRU) was used to define high on-clopidogrel platelet reactivity (HCPR) and a value of 454 aspirin reaction units (ARU) was used to define high on-aspirin platelet reactivity (HAPR). RESULTS In 20 patients aged 31 to 85, in hospital and 6 weeks after STEMI, hs-CRP was 6.7 (SD 4.0) and 2.6 (SD 3.2) respectively, p< 0.01. Changes in ARU from 408.3 (SD 54.3) to 425.2 (SD 68.2) and PRU from 157.8 (SD 74.7) to 164.2 (SD 75) were not statistically significant. 2 patients had HAPR in hospital; 1 became sensitive at follow up. 2 patients developed HAPR and HCPR. We saw a trend towards higher PRU in diabetic patients and those prescribed statins. CONCLUSIONS Although we found a significant difference in hs-CRP levels between the first and second time point, no significant difference was found in on-aspirin and on-clopidogrel platelet reactivity between the time points.Thus, in this small series, the acute inflammatory state associated with STEMI did not appear to influence the on-DAPT reactivity at the dosages used. Trends among those with diabetics and prescribed statins will be discussed

Background: This study evaluated the association of the high-sensitivity C-reactive protein to prealbumin ratio (CPR) with adverse cardiovascular events after ST-elevation myocardial infarction (STEMI) in patients undergoing primary percutaneous coronary intervention (PCI). Methods: The study included 682 patients who presented with STEMI and were treated with primary PCI. Patients were divided into 2 groups: high CPR (CPR ≥0.02) and low CPR (CPR <0.02). The primary endpoint of the study was the occurrence of major adverse cardiovascular events (MACE), defined as cardiovascular mortality or admission due to recurrent AMI or heart failure. Multivariate Cox regression models were used to assess the prognostic value of CPR on MACE in patients with STEMI. Results: During a median follow-up of 18 months, the accumulated incidence rate of MACE was significantly higher in the high-CPR group than in the low-CPR group (38.7% versus 12.0%, P < .01). Multivariate analysis revealed that CPR was an independent predictor for increased risk of MACE (hazard ratio = 3.27, 95% confidence interval [CI] 2.14 to 4.49, P < .01). Receiver operating characteristic (ROC) curve analysis showed that the area under the ROC curve for predicting the diagnosis of MACE was higher for CPR (0.82, 95% CI 0.77 to 0.87) than hs-CRP (0.70, 95% CI 0.65 to 0.75). Conclusion: CPR was independently associated with MACE and can be used for risk stratification in patients with STEMI.
