To develop and test a beat-to-beat blood pressure monitoring device during coronary angiography, and compare it with invasive blood pressure monitoring.
Twenty-eight patients with an indication for hemodynamic study were selected for this investigation, and kept in supine position. Before starting the coronary angiography, they were instructed about the use of the left radial bracelet for beat-to-beat blood pressure monitoring.
There was a significant difference between the time required for the catheterization laboratory team to acquire the first invasive blood pressure reading and the time to obtain the first beat-to-beat reading (11.1±5.1 and 1.5±1.8, respectively; p<0.0001). The intraclass correlation coefficients (95%CI) of systolic and diastolic blood pressures were 0.897 (0.780-0.952) and 0.876 (0.734-0.942), indicating good reproducibility.
This study showed the process to develop a beat-to-beat blood pressure monitoring device. When compared to invasive blood pressure monitoring, there were no significant differences between the two methods. This technique may play a promising coadjuvant role when combined with invasive monitoring during coronary angiography procedures.
研发并测试一种用于冠状动脉造影术中逐搏血压监测的设备，并将其与有创血压监测进行比较。
选取28例有血流动力学研究指征的患者进行本研究，使其保持仰卧位。在开始冠状动脉造影术前，告知他们如何使用左桡动脉手环进行逐搏血压监测。
导管室团队获取首个有创血压读数所需时间与获取首个逐搏读数所需时间之间存在显著差异（分别为11.1±5.1和1.5±1.8；p<0.0001）。收缩压和舒张压的组内相关系数（95%CI）分别为0.897（0.780 - 0.952）和0.876（0.734 - 0.942），表明具有良好的重复性。
本研究展示了研发逐搏血压监测设备的过程。与有创血压监测相比，两种方法之间无显著差异。在冠状动脉造影术过程中，该技术与有创监测相结合时可能发挥有前景的辅助作用。
