Abstract:

Coronary heart disease remains one of the leading causes of cardiovascular mortality.With the in-depth understanding of the pathogenesis of coronary heart disease, it is now widely believed that vulnerable plaques within the coronary arteries are associated with the occurrence of future acute coronary syndromes. The vulnerability of plaques is mainly assessed using intravascular imaging techniques such as Intravascular Ultrasound (IVUS) and Optical Coherence Tomography (OCT). However, these methods require the use of additional interventional consumables, and the analysis is relatively time-consuming,which limits their application in the interventional diagnosis and treatment of coronary heart disease. Recent studies have shown that radial wall strain (RWS) analysis has a high consistency with traditional intravascular imaging techniques in assessing vulnerable plaques, and it can avoid additional interventional costs. RWS is expected to become a routine method for assessing plaque vulnerability and optimizing strategies for coronary intervention. This article provides a review of the principles, workflow, clinical research, and current limitations of RWS.

Key words: Functional angiography, Vulnerable plaque, Coronary angiography, Coronary intervention
