Haemodynamic characterisation of different endotypes in coronary artery vasospasm in reaction to acetylcholine

International Journal of Cardiology: Heart & Vasculature, 2022
Background: Vasoreactivity testing with high-dose acetylcholine is considered vasospasm provocation and low-dose as endothelial function testing. Aims: To assess the changes in reaction to low- and high-dose acetylcholine in the endotypes of CAS as ...
