摘 要 目的：探讨高血压病患者肺静脉血流(PVF)频谱改变与心脏左室、右室功能的关系。方法：用超声方法测量高血压病Ⅰ期组26例、Ⅱ期组22例及20例正常对照组的心功能及PVF频谱参数并做比较。结果：高血压病Ⅰ期组及Ⅱ期组PVF频谱参数较对照组有显著差异(P<0.05，0.001)，且组间差异显著(P<0.05)；高血压病各组E/A较对照组显著降低(P<0.05，0.001)，Ⅱ期组EF及Pa-v较对照组差异显著(P均<0.001)，Ⅰ期组收缩功能参数较对照组差异不明显(P>0.05)；PVF频谱各参数与心脏功能参数相关分析表明，PVa及PVd与ACT/RVET显著相关(r分别为-0.87，0.84)，E/A与PVs/PVd显著负相关(r＝-0.95)。结论：高血压病患者左室及右室舒张功能均降低与高血压病程是递进关系，收缩功能改变在后期有所降低；肺静脉血流频谱对评价高血压病进程有参照意义，特别是PVd降低，PVa增高敏感反映高血压病进程中右室后负荷的改变，影响右室收缩功能。

ABSTRACT Objective:To investigate the relationship of heart function and pulmonary venous flow in patient with hypertension..Methods：Forty-eight hypertenison patients cardiac function parameters in accordance with their pulmonary venous blood flow patterns were studied by echocardiography.20 normal ones took part for control.Results:Parameters of PVF patterns in hypertension groups were significantly abnormally changed(P<0.05 ......
