Abstract
Abstract
This study aimed to analyze the changes in myocardial work (MyW) properties and the correlation of MyW with cardiovascular indices during the pre-eclampsia (PE) pregnancy. Standard two-dimensional and speckle-tracking echocardiography were sequentially performed on 77 women with PE and 89 with normal pregnancy. Four components of MyW: global myocardial work index (GWI), constructive work (GCW), wasted work (GWW), and work efficiency (GWE) were measured. The significant increased GWI, GCW and GWW with decreased GWE were observed, while GWW elevated more than GCW with consequently resulting the decline in GWE in PE cases. Further, there was a various relationship between MyW elements and LV morphological as well as functional parameters. Those findings of MyW in the patients with PE may indicate the changes in cardiac contraction and myocardial metabolism as well as the imbalance between them during PE gestation, which not detected by left ventricular ejection fraction and strain alone.
