In this study of 61 patients (group I: 37 patients with no signs of cardiac failure, group II: 24 patients with signs of cardiac failure), a comparison is made between the indices of left ventricular performance obtained during the isovolumic phase dp/dt/Pt max of the left ventricle (5F Millar micromanometer) and in the ejection phase (ejection fraction, mean speed of fibre contraction, corrected mean systolic ejection speed (left ventricular cineanigiography) and maximal acceleration of the aortic blood flow (electromagnetic velocimeter). Calculations were also made of the modulus of elasticity (Ep) and the characteristic impedance of the ascending aorta (Zo) in every patient. The results show that, for group I patients the correlation between the indices in the isovolumic and ejection phases is improved by taking Zo into account. This result is not true for group II cases except with respect to the acceleration of aortic blood flow. An analysis has been made of the hypotheses and the discrepancies.
在这项针对61例患者的研究中（第一组：37例无心力衰竭体征的患者，第二组：24例有心力衰竭体征的患者），对在左心室等容收缩期（5F Millar微测压计测量dp/dt/Pt max）以及射血期所获得的左心室功能指标进行了比较（射血分数、纤维收缩平均速度、校正平均收缩期射血速度（左心室电影血管造影）以及主动脉血流最大加速度（电磁速度计））。还计算了每位患者的弹性模量（Ep）和升主动脉的特性阻抗（Zo）。结果表明，对于第一组患者，考虑Zo后等容收缩期和射血期指标之间的相关性得到改善。除了主动脉血流加速度外，该结果在第二组病例中不成立。已对这些假设和差异进行了分析。
