What this trial studies

This trial evaluates the effectiveness of integrating coronary computed tomography angiography (CCTA) information into invasive coronary examinations for patients with stable angina pectoris. A total of 120 patients will be randomized into two groups: one receiving standard treatment and the other utilizing a CT-guided algorithm for a more focused examination. The primary goals are to reduce patient radiation exposure, procedure time, and the use of procedural utensils and contrast. The study aims to determine if a more targeted approach can enhance the efficiency and safety of coronary interventions.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 81 with stable angina and at least one coronary artery with significant stenosis.

Not a fit: Patients with significant bleeding risks, known pregnancy, or chronic total occlusion may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to safer and more efficient coronary interventions for patients with ischemic heart disease.

How similar studies have performed: Other studies have shown promise in using imaging techniques to guide interventions, suggesting potential success for this approach.
