Abstract:
0.05).After that,both systolic and diastolic function began to decrease.In 4 weeks after the operation,both the the maximum rate of left ventricular isovolumic systolic pressure + dp/dtmax and the maximum rate of left ventricular isovolumic diastolic pressure-dp/dtmax decreased to the lowest levels [(1249.89 ? 95.82) mm Hg/s and(-1316.40 ? 58.31) mm Hg/s,respectively];and then in 6 weeks after the operation,echocardiography showed that the left ventricular short axis fractional shortening FS reached the lowest level [(18.70 ? 3.83)%].Moreover,we found that the FS was highly related with the + dp/dtmax(r=0.864,P
