Evaluation of Left Atrial Function Changes in Peripartum Cardiomyopathy Using Two-dimensional Speckle Tracking Imaging
摘要
Abstract
Objective To evaluate the changes of left atrial(LA)function in peripartum cardiomyopathy(PPCM)patients using two⁃dimensional speckle tracking echocardiography(2DSTE). Methods Totally 35 PPCM patients and 35 healthy postpartum women(control group)were en⁃rolled in this study. Left ventricular end⁃diastolic diameter(LVEDd)and LA anteroposterior dimension(LAAD)were measured. The end⁃diastol⁃ic volume(EDV)and end⁃systolic volume(ESV)were obtained using biplane modified Simpson′s method. Cardiac output(CO)and left ventricu⁃lar ejection fraction(LVEF)were also calculated. E wave and A wave of mitral valve were measured,and correspondingly E/A ratio were obtained. LA longitudinal systolic strain(SS),systolic strain rate(s⁃SR),early diastolic strain rate(e⁃SR),and late diastolic strain rate(a⁃SR)were ob⁃tained by 2DSTE. Results There was no statistical difference of E wave between the two groups(P>0.05). Compared to the normal control group, LVEDd,EDV,ESV,LAAD,E/A were increased,while CO,LVEF,A,SS,s⁃SR,e⁃SR,a⁃SR were decreased in the PPCM group(P<0.05). a⁃SR was positively correlated with A wave in patients with PPCM(r=0.775,P=0.001). Conclusion LA reservoir,conduit and booster pump func⁃tion were decreased during PPCM. 2DSTE can easily and accurately assess these changes of LA function.关键词
