Introduction & Objective: Percutaneous Coronary Intervention (PCI (can be associated with a small but significant number of symptoms around procedure such as: myocardial infarction, thrombosis, stroke, broad bleeding or death, that among these symptoms, infarction around the procedure is the most common symptom. Therefore, the aim of this study was assessing the incidence of myocardial infarction around the stent and determining the predictive and preventive factors for this symptom. Method: 442 patients based on the previous angiography were candidates for elective PCI. Demographic, laboratory, and angiographic variables and their relationship with the peri-procedure infarction were investigated. Previous ck-MB and 8 and 24 hours were measured. Items that had at least three-time increase from the upper normal limit were considered as PMI. Results: Out of 442 patients with coronary PCI, 40 cases had CK-MB increase  three-times more than the increase in URL (9.44%). 149 (33.7%) were female and 293 (66.3%) were male. Patients with a history of hyperlipidemia and low LVEF, low GFR and high Cr, high CRP, high ureic acid, no or low dose of statin, metformin (in diabetics), more stent, longer lesion length, more balloon sessions, were more likely to suffer from PMI. Conclusion: Caring for renal function and administering adequate doses of statin and minimizing the number of balloon sessions can reduce the risk of post-PCI infarction.
