Coronary CT angiography (CCTA) is the recommended initial test for most patients with suspected coronary artery disease (CAD).1 In preparation for CCTA, lowering the heart rate (HR) is essential to optimize image quality, reduce radiation exposure, and enable advanced techniques such as CT-derived fractional flow reserve – even with modern CT scanners.2–4 A target HR of <60 beats per minute (bpm) during CCTA is recommended for commonly used scanners, primarily to minimize motion-related artif…
