摘　　要：目的 用脉冲多普勒超声评价不同左室构型高血压患者的肺静脉血流曲线。方法 对110例单纯高血压患者(男81例,女29例)进行二维和脉冲多普勒超声检查,根据左室重量及相对室壁厚度分成四种不同构型,比较四组间肺静脉血流曲线特点。结果 110例高血压患者中构型正常者占55.45％(61例),向心性重构者占21.82％(24例),向心性肥厚者占10％(11例),偏心性肥厚者占12.73％(14例)。肺静脉血流曲线示向心性肥厚组及偏心性肥厚组的VTIs、VTIs/(VTIs+VTId)较正常组及向心性重构组低(P<0.05),ARD增大,ARD/AD延长(P<0.005)。结论 左室不同构型的高血压患者肺静脉血流曲线不同,提示向心性肥厚组及偏心性肥厚组左室舒张功能的损害较向心性重构组更明显。Purposes To evaluate the left ventricular diastolic function of hypertensive patients with different left ventricular geometry. Methods 110 patients were studied by the two - dimensional and pulsed Doppler echocardiography. The patients were divided into tour types according to the left ventricular mass and relative wall thickness. Results There were 55.45% patients with normal patterns, 21.82% with concentric remodeling, 10% with concentric hypertrophy and 12.73% with eccentric hypertrophy. The VTIs and VYIs/(VTIs+ VTId) ratio in pulmonary venous flow was Lower in the groups with concentric hypertrophy and eccentric hypertrophy than in the other two groups( P < 0.05 ) . The ARD and ARD/AD ratio were larger also in the two hypertrophic groups(P< 0.05, < 0.005) . Conclusions Left ventricular geometric patterns had effects on its diastolic function of the hypertensive patients.
