The clinical significance of smaller increases in cardiac enzymes following elective percutaneous coronary intervention.

摘要

In their recently published well designed article Yonetsu and coworkers used optical coherence tomography (OCT) to study the relationship between pre-percutaneous coronary intervention (PCI) plaque morphology and post-PCI creatine kinase-MB (CK-MB) elevation [1 ]. Elevated CK-MB levels were observed in 28% of patients. The CK-MB elevation was associated with elevated white blood cell count, type B2/C lesions, the presence of thin cap flbroatheroma (TCFA), plaque rupture, and lipid quadrants. In the multivariate analysis, the presence of TCFA (OR 4.68) and type B2/C lesions (OR 4.20) were independent predictors of post-PCI CK-MB elevation. They concluded that TCFA and angiographically complex lesion morphology can predict post-PCI CK-MB elevation in patients treated with elective stent implantation.
