Background. It is well known that chronic kidney disease is a strong independent predictor of adverse outcomes after percutaneous coronary intervention in patients with ischemic heart disease. Recently, peri-procedural myocardial injury has been associated with adverse cardiac events. The aim of this study was to investigate the relationship between renal function and peri-procedural myocardial injury in patients undergoing elective stent implantation. Methods. This study comprised 273 consecutive patients who underwent elective stent implantation. They were divided into two groups: estimated glomerular filtration rate (eGFR) <60 mL/min/1.73m2 and eGFR≥60 mL/min/1.73m2. Peri-procedural TnT levels higher than three times the normal limit were defined as peri-procedural myocardial injury. Results. Patients with eGFR <60 mL/min/1.73m2 showed a higher incidence of peri-procedural myocardial injury compared to patients with eGFR≥60 mL/min/1.73m2 (4.3 versus 20.9%, P < 0.0001). Even after a multivariate adjustment, the eGFR level predicted peri-procedural myocardial injury [odds ratio 0.92, 95% confidence interval (CI): 0.89-0.95, P < 0.0001]. Total stent length was also an independent predictor of peri-procedural myocardial injury (odds ratio 1.09, 95% CI: 1.02-1.16, P = 0.009). Using a receiver-operating curve analysis, eGFR level of 62.1 mL/ min/1.73m2 (sensitivity 93.3%, specificity 57.2%) was the best value (area under the curve = 0.803) to maximize the power of eGFR levels in predicting peri-procedural myocardial injury. Conclusions. Patients with eGFR <60 mL/min/1.73m2 were strongly associated with peri-procedural myocardial injury after elective stent implantation. Therefore, eGFR may be a simple and convenient predictor of periprocedural myocardial injury.
