Clinical Trial Summary

The most accurate way to determine intra-aortic BP is to obtain invasive measures by vascular catheterization, which is not possible to perform routinely during the regular follow-up of patients. However, in recent years, devices used to estimate central BP have been designed and approved for clinical use. These devices can determine aortic BP in a non-invasive way using various techniques and algorithms and offer a high degree of precision when compared to invasive measurements of intraaortic BP. On the other hand, certain characteristics specific to the different devices mean that the central BP values obtained may not be interchangeable. It is therefore important to determine the degree of agreement of central BP values obtained using commercially available devices. This study aims to determine the degree of agreement between central BP measurements obtained using 4 devices commonly used to measure central blood pressure, i.e. Mobil-o-Graph NG (IEM, Germany), WatchBP Office (Microlife, Taiwan), Oscar 2 with SphygmoCor inside (SunTech, USA) and BP+ (Uscom, Australia). These four devices record the shape of the pulsatile wave and then derive the central BP using an algorithm. The main differences between these devices lie in this algorithm, or "transfer function,", which is unique to each and the calibration used. All use a brachial cuff to capture the pulse waveform and can easily be used in clinical practice.
