摘　　要：目的探讨左心室舒张早期血流传播速度(V_P)与冠状动脉狭窄程度的关系。方法应用彩色M型多普勒测量90例冠心病患者和40例健康志愿者的V_P;根据冠状动脉造影结果计算冠状动脉狭窄程度的Gensini积分。结果冠心病患者V_P均较正常减小,且随着冠状动脉狭窄程度加重,V_P进行性减小(P<0.01);V_P与Gensini积分呈负相关(r=-0.68,P<0.01)。结论左心室舒张功能减退随冠状动脉狭窄程度的加重而逐渐加重,V_P能够较好地反映冠状动脉狭窄程度。Objective To investigate the relationship between left ventrieular early diastolic flow propagation velocity （VP） and severity of coronary artery stenosis by color M-mode Doppler. Methods Using color M-mode Doppler, VP. was measured in 90 patients with coronary artery disease and 40 healthy volunteers. Gensini score was obtained by coronary artery angiography. Results Vp was decreased in patients with the severity of coronary artery stenosis. A significant negative correlation was found between the Gensini score and VP （r= -0.68, P〈0.01）. Conclusions Left ventricular diastolic dysfunction appears in patients with coronary artery disease and further decreases in patients with the .severity of coronary artery stenosis. VP can evaluate the severity of coronary artery stenosis.
