Assessment of Coronary Plaque Composition Using Optical Coherence Tomography
Study type: Interventional What is this?
Describes the nature of a clinical study. Types include:
- Observational study — observes people and measures outcomes without affecting results.
- Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
- Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.

About this study
The investigators hypothesis is that local activation of the endogenous Lp-PLA2 plays an integral role in early atherosclerosis, and contributes to the mechanism of coronary endothelial dysfunction and to the structural and mechanical properties that characterize plaque vulnerability. Thus, the investigators study will characterize prospectively the correlation between the functional and structural vascular wall properties, and the activity of the Lp-PLA2 pathway.
Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.
