First seen Jan 06, 2026 · Last updated Jun 23, 2026 · Updated 29 times
Summary
This study compares three common heart-rate-lowering drugs (metoprolol, atenolol, and ivabradine) to see which one reduces heart rate the fastest in people aged 30-80 who need a cardiac CT scan. 350 participants with a heart rate above 65 beats per minute will receive one of the drugs or a placebo. The goal is to find the best option for getting clear scan images quickly.
