Clinical Value of Measuring Left Ventricular Active Diastolic Force by Two-dimensional and Doppler Echocardiography / 中华超声影像学杂志

We utilized the mass-acceleration concept according to Newton'a second law of motion to establish a mathematieal model of left ventricular active diastolic force by twodimensional and Doppler echocardiography. Twenty normal control subjects and 31 patients with coronary heart diseases were tested. The results showed that the left ventricular active diastolic force of the patients with coronary heart diseases was significantly lower than that of the control group(P<0.001).The authors believe that left veatricular active diastolic force is a reliable candidates for assessing the left ventricular diastolic function.
