Abstract:
Objective To evaluate the left atrial(LA) function in patients with severe preeclampsia ( SPE) by full-volume imaging technology. Methods Forty-two patients of SPE were randomly chosen as SPE group,34 healthy pregnant women were selected as the control group. LA related function parameters including LA maximum volume( LAVmax),LA minimum volume( LAVmin),LA pre-atrium contraction volume(LAVpre),LA reservoir volume(LARV),LA passive emptying volume(LAPEV),LA contraction volume(LACV),LA expansion index(LAEI),LA passive emptying fraction(LAPEF),LA passive emptying fraction( LAAEF ) were separately required by biplane area-length method and full-volume imaging technology in antepartum and postpartum. Results Compared with control group before delivery,the parameters of SPE group before delivery such as LAVmax,LAVmin,LAVpre were higher,LAEI,LAPEF, LAAEF indexed to body surface area(BSA) were lower(all P ＜0.01).Compared with control group before delivery,the parameters of control group after delivery such as LAVmax,LAVmin,LAVpre were lower( all P ＜0.05),LAEI, LAAEF calculated as ratio to BSA were somewhat reduced,LAPEF calculated as ratio to BSA was relatively higher(all P ＞0.05).Compared with SPE group before delivery,the parameters of SPE group after delivery such as LAVmax,LAVmin,LAVpre were lower,LAEI,LAPEF,LAAEF indexed to BSA were higher( all P ＜0.01). Compared with control group after delivery,the parameters of SPE group after delivery such as LAVmax,LAVmin,LAVpre were still incresed ( all P ＜ 0.05 ), LAEI,LAPEF, LAAEF indexed to BSA were relatively lower( all P ＞0.05). Conclusions Full-volume imaging technology can quantitatively evaluate the LA function. LA reservoir function,conduit function and booster pump function are reduced in SPE before delivery,LA rereservoir function,conduit function and booster pump function are basically recovery in SPE after delivery.
