Обзор

Active inflammation plays a key role in causing Coronary Artery Disease (CAD) and Peripheral Arterial Disease (PAD). Since inflammation is so important in how these diseases start, are diagnosed, and treated, being able to see it clearly in each patient could lead to more personalized and effective care - and may help prevent heart attacks. Right now, there's no imaging technology available to clearly see inflammation inside the coronary arteries. The investigators hope to learn how an imaging drug; called LUMISIGHT (Pegulicianine) can help detect inflammation in blood vessels compared with saline. If the investigators find out that LUMISIGHT is active in humans, the investigators might be able to use it for detecting plaque risk in the future.

Подробное описание

Objective of this research is to find out if a new imaging drug called LUMISIGHT can show inflammation inside blood vessels for participants with severe coronary and peripheral arterial disease. This will allow us to obtain information about diseases that cause inflammation in the heart and blood vessels.

On the day of the procedure, at least 2 hours before the surgery, consented study participants will be injected with either the LUMISIGHT or saline. Following the injection, study participants will be monitored and observed for 30 minutes for any allergic reactions. Study participants will then undergo the standard of care surgery for their clinical care. During the procedure, surgeon will take out blocked pieces of subjects' blood vessel for clinical care. The investigators will get these discarded pieces and image it with a special imaging system developed by the Tearney Lab. This system uses a thin tube with a light-based camera (called Optical Coherence Tomography-Near Infra Red Fluorescence or OCT-NIRF) to capture detailed images.
