Study Using Near-Infrared Spectroscopy and Optical Coherence Tomography to Evaluate Coronary Vulnerable Plaques in Adults with Diabetes

What this Trial Is About

Researchers are studying the relationship between a new index called maxLCBI4mmFCTmin, based on NIRS-OCT technology, and the thickness of the fiber cap in coronary plaques in patients with diabetes. The goal is to identify vulnerable plaques early and accurately, and to explore ways to prevent serious heart events like cardiac death and recurrent heart attacks, ultimately aiming to improve long-term patient outcomes. Participants will undergo an NIRS-OCT examination to assess their coronary plaques. This observational study focuses on patients with diabetes who need an OCT examination or treatment guided by OCT. The study does not involve drug treatments but carefully monitors the plaques using advanced imaging technology. During the study, participants will be followed for 24 months after their procedure to track major adverse cardiac events MACE. Researchers will measure the maxLCBI4mmFCTmin ratio and monitor heart health outcomes. The study requires participants to provide informed consent and be available for follow-up assessments over the two-year period.
