OBJECTIVE: Myocardial injury related to percutaneous coronary interventions (PCI) might adversely affect the prognosis of patients with coronary artery disease. Our study aimed to investigate the effects of long-term statin usage on myocardial injury related to elective PCI. METHODS: In our study, total 102 patients were included and evaluated in 3 groups based on the statin usage before PCI, "potent statin" group (n=26), "weak statin" group (n=23), and "statin free" group (n=53). The occurrence of the procedural complications was identified (n=31). The myocardial injury was determined by serial high-sensitivity troponin T (hsTnT) testing at 0th, 2nd, 4th, and 12th hour of the procedure. RESULTS: The increase in hsTnT values in the 2nd and 4th hour was significantly lower in the potent statin group than in the other 2 groups (p=0.008 and p=0.009, respectively). In patients with procedural complications, the increase in hsTnT levels at the 2nd, 4th, and 12th hour were also lower in the potent statin group (p=0.032, p=0.019, and p=0.006, respectively). Also, in patients with procedural complications, hsTnT levels exceeding the myocardial infarction limit at the 4th and 12th hour were lower in the potent statin group (p=0.039 and p=0.006, respectively). CONCLUSION: These results show that elective PCI related myocardial injury was less frequent in patients who were using high-dose statins. This result was more pronounced in patients who developed complications during the procedure.
