摘要：Objectives Assessment of diastolic function is vital to impart information relevant to patients' cardiac functional class, diagnosis and management. We sought to investigate diastolic function under normal systolic function and systolic dysfunction and pseudonormalized phenomena.Methods 36 normal subjects( Group Ⅰ), 33 patients with coronary artery disease(CAD) (Group Ⅱ) and 74patients with essential hypertension(EH) (Group Ⅲ)were studied by color M-mode Doppler echocardiogrphy. The rate of propagation of peak early filling flowvelocity(Vp), time delay(TD) of the peak early fillingflow velocity from mitral tips to the apex, Vp/E andother parameters were measured by color M-modeDoppler echocardiography. Results Three groups had no statistical differences in gender, age and heart rate. There were significant differences of Vp, TD and Vp/E ratio between systolic dysfunction group and normal systolic function group. The result also showed significant differences in Vp, TD and Vp/E between pseudonormal group and control group( P ＜ 0.01Conclusion The rate and time of propagation of peak early filling flow velocity (Vp, TD, Vp/E) by M -mode color Doppler echocardiography are more precise and reliable parameters to evaluate LV diastolic function by distinguishing pseudonormalized transmitral flow pattern.
