Abstract:
Using Low Shear-30 rheometer, we studied apparent viscosities at high (51.2-128.5s~(-1)), moderate (11.02-37.6s~(-1)), and Low (0.376-8.11s~(-1)) shear rate, viscoelastic properties of whole blood and hemodynamic parameters in 10 patients with acute myocardiac infarction(AMI), comparing with 10 patients with angina pectoris (AP) and 11 normal subjects(NS). It was demostrated that the apparent viscosities of whole blood at different shear rates mentionned above and viscoelastic properties of whole blood (the dynamic modulus G′, the loss modulus G″, "the viscous ?′ and the elastic component ?″ of complex viscosity) increased distinctly and parameters of cardiac function (EF, CO, LVET, PEP/LVET, HI, SV and CI) were abnormal obviously in AMI, in comparing with AP and NS (P
