目的应用超声心动图评估妊娠期高血压疾病患者妊娠晚期心脏形态及心功能变化。方法2003年1月至2005年1月采用彩色多普勒超声诊断仪测量53例妊娠期高血压疾病患者及22例正常妊娠者孕晚期心脏房室腔大小、左室壁厚度及心包积液,以左室射血分数(EF)、心输出量(CO)、心脏指数(CI)及二尖瓣舒张早、晚期峰值(E峰、A峰)、E/A比值、舒张早期快速充盈分数(RFF)作为评价心功能的指标。结果与正常组对比,妊娠期高血压疾病组室间隔及左室后壁增厚(P均<0.01),左房增大(P<0.01),心包积液发生率增高(P<0.05),异常左室构型发生率为35.8%;E/A比值及RFF下降(P均<0.05),重度子疒间前期患者E/A比值小于1,并有2例EF低于50%。结论妊娠期高血压疾病患者妊娠晚期心脏形态变化以左室壁增厚、左房增大及心包积液为主。重度子疒间前期患者左室舒张功能损害,个别病例收缩功能受损。
Objective To evaluate the changes of cardiac morphology and cardiac function in late pregnancy in patients with gestational hypertension by echocardiography. Methods From January 2003 to January 2005, 53 cases of hypertensive disorder complicating pregnancy and 22 normal pregnant women were enrolled in this study. The size of the atrioventricular cavity, left ventricular wall thickness and pericardial effusion were measured by color Doppler sonography. The left ventricular ejection fraction (EF), cardiac output (CO), cardiac index (CI) and early diastolic mitral valve, late peak (E peak, A peak), E / RFF) as an indicator of cardiac function. Results Compared with the normal group, the interventricular septum and the posterior wall thickening of the left ventricle in hypertensive disorder complicating pregnancy (P <0.01), the left atrium increased (P <0.01), the incidence of pericardial effusion increased (P <0.05) The incidence of abnormal left ventricular configuration was 35.8%. The E / A ratio and RFF decreased (P <0.05), and the E / A ratio in patients with severe preeclampsia was less than 1, and two cases of EF less than 50%. Conclusion The changes of heart shape in late pregnancy in patients with gestational hypertension are mainly left ventricular wall thickening, left atrium enlargement and pericardial effusion. Severe subependymal left ventricular diastolic dysfunction, individual cases of impaired systolic function.
