A, Proposed testing strategy in patients with possible acute coronary syndrome (ACS). *Contraindications to computed tomographic angiography (CTA) include renal disease, severe allergy to iodine contrast, inability to follow breath-hold instructions, and pregnancy. Also consider factors that may impair image quality: body mass index >40 kg/m2, arrhythmias, high heart rate despite β-blockers, extensive coronary calcifications, and intolerance or contraindication to β-blockers or nitroglycerin.

4. Coronary computed tomographic angiography (CTA) demonstrating nonobstructive coronary artery disease.
Coronary computed tomographic angiography (CTA) demonstrating nonobstructive coronary artery disease. Top row, Three-dimensional and curved multiplanar views of the left anterior descending artery (LAD), left circumflex artery (LCX), and right coronary artery (RCA). There is noncalcified and calcified plaque in the proximal and mid-LAD, resulting in mild (25%–49%) stenosis. Bottom row, Orthogonal and short-axis views of mid-LAD demonstrating (b) predominant calcified plaque in the mid-LAD, resulting in mild (25%–49%) stenosis relative to (a) proximal and (c) distal reference vessels.
