摘　　要：　目的　检测肥厚型心肌病(HCM)左心室舒张早期血流传播速度(VP)的变化,探讨其临床价值。方法　选择HCM患者52例和健康志愿者 30 例,应用彩色 M型多普勒超声测量 VP。结果　与正常组比较,HCM组VP 显著减小( t=8.42,P<0.001),Spearman 等级相关分析显示VP 与左心室舒张功能分级之间存在良好相关性( r=-0.71,P<0.001)。结论　HCM患者VP 较正常人减小,且随着左心室舒张功能减低程度的加重而减小,为左心室舒张功能的评估提供了一个更好的途径。Objective To measure the alteration of early diastolic flow propagation velocity (V P) of left ventricle in patients with hypertrophic cardiomyopathy(HCM),and to investigate its clinical value.Methods Using color M-mode Doppler echocardiography,V P was measured in 52 patients with HCM and 30 healthy volunteers.Results Compared with normal control,V P in patients with HCM was decreased significantly (t= 8.42,P< 0.001).Spearman rank analysis showed there was a good correlation between V P and the degree of left ventricular diastolic function (r= -0.71,P< 0.001).Conclusions V P may be used to evaluate left ventricular diastolic function accurately in the patients with HCM.
