To detect regional of left ventricular myocardial function in patients with metabolic syndrome (I and II group) using Strain Rate imaging (SRI).
64 patients with MS were enrolled in the study. MS I group (n=32) and MS II group (n=32);32 healthy adults as control group. SRI was used to detect srain rate. And Qlab online analysis software was used to analyze each group.
1, Left ventricular regional longitudinal and circumferential peak strain rate(SRS) analysis: (1)Compared with control group, SRS were all declined significantly in MSI, IIgroup (p <0.05); Comparison between MS I group and MS II group, SRS were all declined significantly in MSIgroup (p < 0.01 0.05). 2, Left ventricular regional peak radial strain rate(SRS) analysis: Compared with control group,SRS was obviously reduced in part of segment of left ventricular in MSI, IIgroup(p < 0.05); Comparison between MS I group and MS II group, SRS was obviously reduced in mitral valve of after left ventricular interval in MS I group (p < 0.05). 3, ROC curve analysts showed that, the curve of Left ventricular regional longitudinal peak strain rate had certain diagnostic accuracy for MS I group. The best diagnostic cut-off point was -1.29s- 1.
SRI can detect early regional left ventricular myocardial function dysfunction.
