ObjectivesTo assess the predictive value of C-reactive protein (CRP) on periprocedural myocardial injury (PMI), evaluated by creatine kinase-myocardial band isoform (CK-MB) elevation in patients undergoing percutaneous coronary intervention (PCI) with drug-eluting stent (DES) implantation for the treatment of coronary bifurcation lesions is actually unknown.
BackgroundSystemic inflammation as assessed by CRP has been associated with averse events after DES implantation. After PCI, the occurrence of PMI is common and has also been associated with worse outcomes. Finally, bifurcations are frequently encountered anatomically complex lesions which the treatment is associated with higher complication rate compared with simple lesions.
MethodsA total of 96 patients (6610 years, 70 men) from the Coronary bifurcations: Application of the Crushing Technique Using Sirolimus-eluting stents (CACTUS) trial who had baseline CRP dosage and both baseline and postprocedural CK-MB measurement were included.
ResultsA complex bifurcation strategy was implemented in 53 (55%) patients, and angiographic success was achieved in all but two (2%) patients. Periprocedural myocardial necrosis (increase of CK-MB between one and three times the upper limit of normal [ULN]) was observed in 12 (13%) patients, and four (4%) patients had PCI-related myocardial infarction (increase of CK-MB more than three times ULN). Notably, progressively higher CRP levels were observed in patients with different increase in CK-MB (P=0.041). Moreover, CRP >1 mg/L significantly predicted CK-MB rise (odds ratio 5.6, 95% confidence interval 1.5-4.3, P=0.011).
ConclusionIn the setting of true coronary bifurcations treated by DES, baseline CRP levels were significantly associated with both the incidence and the extent of PMI.
