Key result
Wave intensity analysis is a time-domain technique that enables the direct association between waves and events during the cardiac cycle, contributing to physiological and clinical findings.
Wave intensity analysis is a valuable time-domain technique for investigating cardiovascular hemodynamics and interactions in the ventricles, carotid, and coronary arteries.
Enhances wave-based hemodynamic insights in ventricles and arteries; leaves open routine clinical adoption pending prospective validation.
Wave intensity analysis (WIA) was introduced 25 years ago for the study of arterial wave travel and has since been established as a powerful tool for the investigation of cardio-vascular interaction. Despite the complex mathematical derivation of the method, the implementation is simple. As a time-domain technique, WIA enables the direct association between waves and events during the cardiac cycle. Furthermore, it enables the separation of the pressure (or diameter), velocity and wave intensity waveforms into their forward and backward components, and provides a means for the determination of the timing and magnitude of waves of different origins. Hemodynamic questions at several locations along the vascular tree have been investigated with WIA. Part 2 of this review will focus on the physiological and clinical findings to which WIA has contributed, through clinical and in vivo studies in the ventricles and in the coronary and carotid arteries.
