Heart study: is early catheterization better than drugs for chest pain?
NCT ID NCT05865600
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at 570 people with chronic coronary syndrome (chest pain or shortness of breath due to narrowed heart arteries). Participants with abnormal blood flow on a PET scan will be randomly assigned to either immediate heart catheterization or a 3-month delay, while both groups receive optimized heart medications. The goal is to see which approach better relieves symptoms after 3 months.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
guideline-directed medical therapy (heart medications) and invasive coronary angiography (heart catheterization)
What this could lead to
If it works, this could show that early heart catheterization is better than medication alone for relieving chest pain in people with chronic coronary syndrome.
What could go wrong
This is a medium-sized trial (570 people) and results may not apply to everyone. The benefit of early catheterization may be small or not outweigh risks like complications from the procedure.
