Abstract:
Objective To investigate the ability of myocardial fractional flow resever (FFRmyo) in predicting the incidence of major cardiac events (death, myocardial infarction, revascularization and recurrance of angina) 3 months after stent inplantation and also try to find out the cutoff point. Methods Coronary pressure was measured in 79 patients with stable angina immediately after stent implantation. The values of poststenting FFRmyo was calculated and found to be related to the presence of major adverse cardiac events during first 3 months. Results In 14 patients (18.4%), at least one adverse event occurred. Two out of 12 patients experienced recurrance of angina and underwent revascularization. By Logistic Regress analysis, FFRmyo immediately after stenting was the most significant independent variable for predicting major cardiac events. By receiver-operating characteristic (ROC) analysis, the cutoff point of FFRmyo was 0.92. Conclusion FFRmyo immediately after stenting is an independent predictor of clinical events at first 3 months.
