Evaluating strategies to reduce unnecessary heart imaging tests for stable chest pain

Optimal Evaluation of Stable Chest Pain to Reduce Unnecessary Utilization of Cardiac Imaging Testing

NA · Tianjin Chest Hospital · NCT05640752

This study is testing two different ways to see if they can help doctors better identify patients with stable chest pain who don’t need unnecessary heart imaging tests.

What this trial studies

The OPERATE trial aims to improve the evaluation of patients with stable chest pain suggestive of chronic coronary syndrome by comparing two diagnostic strategies based on current guidelines. This multicenter, randomized controlled trial will include 800 subjects who will be assigned to either the NICE or ESC strategy to determine which approach better identifies low-risk patients who may not benefit from coronary computed tomography angiography (CCTA). The primary goal is to assess the rates of CCTA without obstructive coronary artery disease (CAD) and to evaluate the safety of both strategies over a one-year follow-up period. By optimizing diagnostic strategies, the study seeks to minimize unnecessary imaging tests and improve patient management.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 30 and older with stable chest pain suggestive of chronic coronary syndrome and no history of coronary artery disease.

Not a fit: Patients with a history of coronary artery disease, clinically unstable conditions, or those who have undergone cardiac imaging within the past year may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more accurate identification of low-risk patients, reducing unnecessary imaging tests and associated healthcare costs.

How similar studies have performed: Previous studies have explored similar diagnostic strategies, but this trial aims to provide prospective data on their effectiveness in clinical practice.
