What this trial studies

The NIMBLE-I study is a pilot clinical trial evaluating the feasibility and safety of a novel non-invasive device called the NIMBLE system for detecting complications related to coronary stents, particularly in-stent restenosis. Conducted at the Hospital Germans Trias i Pujol in Spain, this single-center trial aims to provide a safer alternative to traditional invasive diagnostic methods. The NIMBLE system utilizes microwave interferometry to monitor changes in the stent environment without the need for ionizing radiation or invasive procedures. The study will assess the usability and preliminary performance of this innovative approach in patients scheduled for coronary angiography.

Who should consider this trial

Good fit: Ideal candidates include patients who have had one or more coronary stents implanted and are experiencing symptoms suggestive of stent failure.

Not a fit: Patients with implanted electronic devices like pacemakers or those unable to provide informed consent may not benefit from this study.

Why it matters

Potential benefit: If successful, this device could significantly reduce the need for invasive procedures in monitoring coronary stent complications, improving patient safety and comfort.

How similar studies have performed: While the approach of using non-invasive monitoring for stent complications is innovative, similar studies have shown promise in other non-invasive diagnostic technologies.
