In 30 patients, simultaneous measurements of ascending aortic pressure and diameter were performed, allowing one to evaluate: (1) the influence of age, the aortic diastolic pressure, and the radius on the aortic elasticity; (2) the correlations between characteristics impedance of the aorta (Zo), systemic arterial resistance, age and diastolic aortic pressure; and (3) the importance of Zo when comparing two indices of left ventricle performance; one during isovolumic phase ([dP/dt]/Pt)max and the other during the outflow phase (maximum acceleration of aortic blood flow).
对30名患者同时进行升主动脉压力和直径测量，从而能够评估：(1)年龄、主动脉舒张压和半径对主动脉弹性的影响；(2)主动脉特征阻抗(Zo)、体循环动脉阻力、年龄和主动脉舒张压之间的相关性；以及(3)在比较左心室功能的两个指标时Zo的重要性，一个指标是等容相([dP/dt]/Pt)max，另一个指标是射血相(主动脉血流最大加速度)。
