Abstract:
Objective To observe the value of three-dimensional speckle tracking imaging(3D-STI)in evaluation on right ventricle(RV)function for predicting adverse events in patients with unstable angina(UA)after percutaneous coronary intervention(PCI).Methods A total of 155 UA patients who underwent both 3D-STI and conventional echocardiography and planned to accept PCI were prospectively enrolled and divided into adverse event group(n=37)and control group(n=118)based on the occurrence of adverse events after PCI or not.Clinical data and echocardiographic parameters were compared between groups,and new binary variables were generated according to the optimal cut-off values showed by the maximum Youden index of receiver operating characteristic curves of 3D-STI parameters being statistically different between groups.Then the independent predictors of adverse events among UA patients after PCI were analyzed,a combined model was constructed,and its predictive value was assessed.Results In adverse event group,the left ventricular end diastolic volume(LVEDV)was higher,while the left ventricular ejection fraction(LVEF),right ventricular free wall longitudinal strain(RVFWLS)and right ventricular global longitudinal strain(RVGLS)were all lower than those in control group(all P＜0.05).The optimal cut-off values for distinguishing adverse event or not was 110 ml for LVEDV,19.05%for RVFWLS and 19.75%for RVGLS,respectively,and all the 3 generated binary variables were independent predictors for adverse events of UA patients after PCI(all P＜0.05).The area under the curve of combined model for predicting adverse events in UA patients after PCI was 0.864.Conclusion RVFWLS＜19.05%and RVGLS＜19.75%obtained with 3D-STI,as well as LVEDV＞110 ml with conventional echocardiography were all independent predictors of adverse events in UA patients after PCI.
