Predictive value of combined detection of fractional flow reserve and serum troponin Ⅰ level for MACE after PCI
Objective:To investigate predictive value of combined detection of fractional flow reserve(FFR)and serum cardiac troponin Ⅰ(cTnⅠ)level for major adverse cardiovascular events(MACE)after percutaneous coronary intervention(PCI).Methods:The clinical data of 80 patients with coronary heart disease who underwent PCI in this hospital from January 2021 to December 2023 were retrospectively analyzed.According to whether MACE occurred during postoperative hospitalization,they were divided into occurrence group(n=47)and non-occurrence group(n=33).The levels of FFR and serum cTnⅠ were compared between the two groups.Receiver operating characteristic(ROC)curve was used to analyze the predictive value of single and combined detection of FFR and serum cTnⅠ level for MACE after PCI.Results:The FFR of the occurrence group was lower than that of the non-occurrence group,the serum cTnⅠ level was higher than that of the non-occurrence group,and the differences were statistically significant(P＜0.05).The ROC curve analysis showed that the area under the curve of single and combined detection of FFR and serum cTnⅠ level for predicting MACE after PCI were 0.768,0.738 and 0.890,respectively,and the combined detection had the highest predictive value.Conclusions:The predictive value of combined detection of FFR and serum cTnⅠ level for MACE after PCI is higher than that of single detection.
