Peri-procedural myocardial damage (MD) is associated with increased risk of major in-hospital complications and adverse clinical events. The aim of this study was to evaluate the effects of on-clopidogrel platelet aggregation and CYP2C19-reduced-function gene variants on elective percutaneous coronary intervention (PCI)-related MD. We measured changes in serum high-sensitive troponin T (hs-TnT) levels, CYP2C19 genotype, and on-clopidogrel platelet aggregation (PA) using VerifyNow(®) P2Y12 system in 91 patients who received stent implantation (stent group). The control group comprised 30 patients who did not receive PCI. Blood samples were obtained before and 24 h after PCI or coronary angiography (CAG). Patients of the stent group were divided into high and low MD groups based on the median value of hs-TnT level at 24 h after PCI. Serum hs-TnT levels were significantly higher 24 h after PCI (86.8 ± 121.5 pg/ml) compared with before PCI (9.4 ± 5.3, p < 0.001), whereas the levels were identical before and 24 h after CAG in the control group. Simple logistic regression analysis demonstrated that MD correlated with age (p = 0.014), estimated GFR (p = 0.003), hemoglobin A1c (p = 0.015), baseline serum hs-TnT (p = 0.049), and stent length (p < 0.001). Multiple logistic regression analysis identified old age, high hemoglobin A1c level, and long stent, but not CYP2C19 reduced-function allele or high on-clopidogrel PA, as independent predictors of elective PCI-related MD. The present study demonstrated no significant relation between peri-procedural MD and high on-clopidgrel PA associated with CYP2C19 reduced-function allele in patients undergoing elective PCI.
