FIGURE 1. Clinical Assessment of Myocardial Ischemia and CAD.
In SCOT-HEART,33 most patients with suspected stable coronary artery disease (CAD) did not have epicardial coronary obstructions, with the vast majority (~4 in 5) having angina and/or ischemia not due to epicardial stenoses. CCTA = coronary computed tomography angiography; CMD = coronary microvascular dysfunction; CV = cardiovascular; INOCA = ischemia with no obstructive coronary arteries; MI = myocardial infarction; OMT = optimal medical therapy.
