Abstract:
Objective To observe the risk factors of ischemic mitral regurgitation(IMR)in ischemic cardiomyopathy.Methods Totally 143 patients with ischemic cardiomyopathy were retrospectively enrolled and divided into IMR+group(n=68)or IMR-group(n=75)based on IMR,while 50 healthy volunteers were taken as controls(control group).The general information,conventional ultrasonic parameters of left ventricle,three-dimensional speckle tracking imaging(3D-STI)parameters as well as mitral valve structural and functional parameters were compared among groups,and the risk factors of IMR were screened with logistic regression analysis.Results Significant differences of left ventricular end-diastolic volume(LVEDV),left ventricular end-systolic volume(LVESV),left ventricular global longitudinal strain(LVGLS),the peak systolic twist(Twist),tenting volume(VTent)and total leaflet area(TLA)/annulus area(AA)were found between IMR+group and IMR-group(all P＜0.05).Decreased LVGLS,decreased Twist and increased VTent were all independent risk factors of IMR in ischemic cardiomyopathy(all P＜0.05).Conclusion Decreased LVGLS,decreased Twist and increased VTent were independent risk factors of IMR in ischemic cardiomyopathy.
