摘要

本文展示了一种利用常规超声心动图中收集的以下五个血液动力学参数评估心血管总硬度的新方法:(1) 左心室每搏量;(2) 左心室射血期;(3) 心率;(4) 收缩压;(5) 舒张压。这项研究使用了在密苏里大学医院接受常规超声心动图检查的八名志愿者患者。脉搏波速度(PWV)数据在超声心动图检查后立即采集,并与超声心动图数据得出的心血管僵化结果进行比较。这一比较的 R2 值为 0.8499,显示出良好的相关性。我们假设,我们评估心血管总僵硬度的新方法可被视为等同于脉搏波速度法。

A New Method for Assessing Total Cardiovascular Stiffness—Preliminary Data
This paper demonstrates a new method for assessing total cardiovascular stiffness using the following five hemodynamic parameters gathered during a routine echocardiogram: (1) left ventricular stroke volume, (2) left ventricular ejection period, (3) heart rate, (4) systolic blood pressure, and (5) diastolic blood pressure. This study uses eight volunteer patients undergoing a routine echocardiogram at the University of Missouri Hospitals. Pulse wave velocity (PWV) data was taken immediately after the echocardiogram and compared to the cardiovascular stiffness result obtained from the echocardiogram data. The R2 value for this comparison was 0.8499 which shows a good correlation. We hypothesize that our new method for assessing total cardiovascular stiffness may be considered equivalent to that of the PWV method.
