Randomized Controlled TrialDiltiazem as an alternative to beta-blocker in coronary artery computed tomography angiography.
Reducing heart rate (HR) in CT angiography of the coronary arteries (CTACor) is critical to image quality. The effectiveness of calcium channel blockers as alternatives for patients with contraindications to beta-blockers has not been established. ⋯ We conclude that diltiazem is an effective and safe alternative to beta-blockers in the reduction of HR when performing computed tomography angiography of coronary arteries.
