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,VP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.
目的 探討左心室舒張早期血流傳播速度(V_P)與冠狀動脈狹窄程度的關繫.方法 應用綵色M型多普勒測量90例冠心病患者和40例健康誌願者的V_P;根據冠狀動脈造影結果計算冠狀動脈狹窄程度的Gensini積分.結果 冠心病患者V_P均較正常減小,且隨著冠狀動脈狹窄程度加重,VP進行性減小(P<0.01);V_P與Gensini積分呈負相關(r=-0.68,P<0.01).結論 左心室舒張功能減退隨冠狀動脈狹窄程度的加重而逐漸加重,V_P能夠較好地反映冠狀動脈狹窄程度.

Objective To investigate the relationship between left ventricular early diastolic flow propagation velocity(V_P)and severity of coronary artery stenosis by color M-mode Doppler.Methods Using color M-mode Doppler,V_P was measured in 90 patients with coronary artery disease and 40 healthy volunteers.Gensini score was obtained by coronary artery angiography.Results V_P was decreased in patients with the severity of coronary artery stenosis.A significant negative correlation was found between the Gensini score and V_P(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.V_P can evaluate the severity of coronary artery stenosis.
