Prognostic Implications of Creatine Kinase Elevation After Primary Percutaneous Coronary Intervention for Acute Myocardial Infarction
چکیده انگلیسی

ObjectivesWe examined the prognostic implications of the absolute level and rate of increase of creatine kinase (CK) elevation after primary percutaneous coronary intervention (PCI).BackgroundPeak creatine kinase (CKpeak) and the rate of CK increase are related to reperfusion success and clinical outcomes after thrombolytic therapy for acute myocardial infarction (AMI). The utility of routine serial CK monitoring after primary PCI, in which normal antegrade blood flow is restored in most patients, is unknown.MethodsIn the Controlled Abciximab and Device Investigation to Lower Late Angioplasty Complications (CADILLAC) trial, 1,529 patients with AMI randomized to either stenting or balloon angioplasty, each with or without abciximab, had CK levels determined at baseline and at 8 ± 1 h, 16 ± 1 h, and 24 ± 1 h after PCI.ResultsThe CKpeakoccurred at baseline in 3.9% of patients, at 8 ± 1 h in 69.6%, at 16 ± 1 h in 20.0%, and at 24 ± 1 h in 6.5%. The CK levels at all post-procedural time points were significantly higher in patients who died compared with the one-year survivors, as was CKpeak(mean, 2,865 U/l vs. 1,885 U/l, respectively, p ≤ 0.001). By multivariate analysis, CKpeakwas a significant predictor of one-year mortality (hazard ratio = 2.15, p = 0.0002), independent from post-PCI Thrombolysis In Myocardial Infarction (TIMI) flow. Both the improvement in left ventricular ejection fraction from baseline to seven months and its absolute level were inversely correlated with CKpeak(p < 0.001 for both). In contrast, the time to CKpeakwas not an independent predictor of mortality or myocardial recovery.ConclusionsThe CKpeakafter primary PCI is a powerful predictor of one-year mortality independent of other clinical and angiographic measures.
