We will do this by looking at differences in their Seattle Angina Questionnaire (SAQ) scores and their health outcomes over a three-year period.",[26,27,28,29],"Coronary Microvascular Dysfunction (CMD)","Stable Angina Pectoris","Unstable Angina Pectoris","Myocardial Ischemia, Angina Pectoris",[31,32,33,34,35],"Hemodynamics","Computational fluid dynamics","Angiography-derived IMR","coronary microvascular dysfunction","stable and unstable angina","NOT_YET_RECRUITING","2025-04-24",{"date":39,"type":40},"2025-04-27","ACTUAL",{"date":42,"type":22},"2025-07-01",{"date":44,"type":22},"2029-12-30",{"name":46,"class":47},"Ge Junbo","OTHER",""]
