What is the recommendation for Coronary Computed Tomography Angiography (CCTA) in patients with known Stable Ischemic Heart Disease (SIHD) who have new or worsening symptoms not consistent with Unstable Angina (UA), irrespective of ability to exercise?
CCTA for assessment of patency of Coronary Artery Bypass Graft (CABG) or of coronary stents 3 mm or larger in diameter might be reasonable in patients with known SIHD who have new or worsening symptoms not consistent with UA, irrespective of ability to exercise. CCTA might also be reasonable in the absence of known moderate or severe calcification.
