ABSTRACT
Objective:
To study the value of speckle tracking echocardiography (STE) for assessing left ventricular remodeling (LVR) in patients of acute ST-elevation myocardial infarction (STEMI) with late percutaneous coronary intervention (PCI).Methods:
A total of 127 STEMI patients with elective PCI were enrolled. Echocardiography was conducted within 48 hours of admission and the patients were followed-up for 6-9 (median 7.8) months after discharge. LVR was deifned by left ventricular end-systolic volume (LVESV) elevation >15% than the ifrst echocardiography. The patients were divided into 2 groups LVR group,n=41 and Non-LVR group,n=84.Results:
There were significant differences between 2 groups in left ventricular global longitudinal strain (GLS), longitudinal Ts-SD, radial strain (RS) and longitudinal postsystolic index. Further Logistic regression analysis indicated that GLS (OR=0.39, 95% CI 0.26-0.57,P<0.01) and RS (OR=1.07, 95% CI 1.02-1.13,P=0.01) were the independent predictors for LVR occurrence; ROC presented that the optimal cut-off value for GLS was -10.85% (sensitivity 89.7%, specificity 91.7%) and for RS was 28.46% (sensitivity 82.1%, speciifcity 66.7%).Conclusion:
STE measured GLS and RS were the independent predictors for LVR occurrence in STEMI patients with late PCI.
