摘要
目的应用全容积成像技术评价重度子痫前期（SPE）患者左心房功能。方法随机选取SPE患者42例作为SPE组，34例健康孕妇作为对照组，产前产后均使用双平面一面积长度法和全容积成像技术分别获取左房相关功能参数，包括左房最大容积（LAVmax）、左房最小容积（LAVmin）、左房收缩前容积（LAVpre）、左房储存容积（LARV）、左房被动排空容积（LAPEV）、左房收缩容积（LACV），标化的左房膨胀指数（LAEI）、左房被动排空分数（LAPEF）、左房主动排空分数（LAAEF），并进行比较。结果与对照组产前比较，SPE组产前LAVmax、LAVmin、LAVpre均升高，标化的LAEI、LAPEF、LAAEF均降低，差异有统计学意义（P〈0．01）；与对照组产前比较，对照组产后LAVmax、LAVmin、LAVpre均降低，差异有统计学意义（P〈0．05），标化的LAEI、LAAEF降低，LAPEF升高，差异无统计学意义（均P〉0．05）；与SPE组产前比较，SPE组产后LAVmax、LAVmin、LAVpre均降低，标化的LAEI、LAPEF、LAAEF均升高，差异有统计学意义（P〈0．01）；与对照组产后比较，SPE组产后LAVmax、LAVmin、LAVpre仍显著高于对照组产后，差异有统计学意义（均P〈0．05），标化的LAEI、LAPEF、LAAEF均降低，差异无统计学意义（P〉0．05）。结论全容积成像技术能定量评估SPE患者左房功能；SPE患者产前左房储存功能、通道功能及泵功能均降低，SPE患者产后左房储存功能、通道功能及泵功能基本恢复。
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 d0.01）. Compared with control group before delivery, the parameters of control group after delivery such as LAVmax, LAVmin, LAVpre were lower（all P d0.05）, 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 d0.01）. 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 I.A 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 hasically recovery in SPE after delivery.
