Comparison of syntax score and syntax score II to predict peri-procedural myocardial injury during percutaneous coronary intervention

Background Peri-procedural myocardial infarction(PPI) is an increase in cardiac enzymes during percutaneous coronary intervention. The development of this condition is associated with a poor prognosis. In this study, we aimed to evaluate the development of PPI in patients undergoing elective percutaneous coronary intervention and the factors that predict patients who developed PPI. Method: A total of 160 consequtive patients who underwent percutaneous coronary intervention were enrolled in the study. Patients were divided into two groups as PPI developing and not developing PPI. The clinical characteristics, laboratory and angiographic features of groups were compared. The SS and SS II was calculated by using the online calculator. Results PPI was devoloped in 44 (27.5%) patients during PCI procedure. SS ,SSII, glomerular filtration rate (GFR), age were identified as independent predictors of PPI. A higher rate of PPI was observed in those with SSII over 35. When compaired of the ROC curves showed that area under curve of SS II was larger than that of SS (AUC 0.855 vs. 0.741, p = 0.039) Conclusion In the study; age GFR, SS and SSII were observed to be independent predictors of PPI. SSII may be a more useful tool than SS for prediction PPI during elective percutaneous coronary intervention.
