Normal

Test choice should be guided by local availability and expertise.
* Known CAD is prior MI, revascularization, known obstructive or nonobstructive CAD on
invasive or CCTA.
† If extensive plaque is present a high-quality CCTA is unlikely to be achieved, and stress
testing is preferred
‡ Obstructive CAD includes prior coronary artery bypass gra/percutaneous coronary
intervention.
§ High-risk CAD means le main stenosis ≥ 50%; anatomically significant 3-vessel disease
(≥70% stenosis).
