Eligibility criteria

Inclusion

Participants with stable CAD or acute coronary syndromes undergoing invasive coronary angiography in the MGH cardiac catheterization laboratory
Participant is eligible for PCI
Participants must be over the age of 18
Participant must be able to give informed consent
Women with childbearing potential must have a negative pregnancy test within seven days prior to the procedure

Exclusion

Renal insufficiency (GRF\<45 ml/min/1.73m2)
Pregnancy
Acute myocardial infarction: Participants with ST elevation MI will be excluded for at least 72 hours post event. Participants with non-ST elevation MI will be excluded if they have evidence of ongoing ischemia defined as chest pain or new ECG changes in the previous 12 hours and/or rising cardiac biomarker enzymes (e.g., troponin or CKMB)
Evidence of ongoing or active clinical instability, including acute chest pain (sudden onset), cardiogenic shock, unstable blood pressure with systolic blood pressure \<90 mmHg, and severe congestive heart failure (NYHA III or IV) or acute pulmonary edema,
Emergent procedures
Ejection fraction \<= 35%
Clinically significant bleeding within the past 14 days
Any active, serious, life-threatening disease with a life expectancy of less than 12 months
Inability to be evaluated at follow-up
Currently enrolled in another study utilizing OCT imaging, or in an investigational trial that involves a non-approved cardiac drug or device
Participants under the protection of justice, guardianship, or curatorship
Participant deemed not indicated for intravascular imaging or PCI
Inability to perform intravascular imaging of a target artery
Left main disease \>= 50% stenosis in participants that do not have a functioning LAD bypass graft
Clinical instability that develops after IVUS imaging but prior to OCT-NIRAF imaging

What this trial measures

  • Plaque size estimation using OCT-NIRAFData will be analyzed within 1 year after the procedure.

    Optically derived signatures (OCT-NIRAF) will be compared to plaque volume measured by CCTA at baseline.

  • Plaque progression estimate using OCT-NIRAFData will be analyzed within 1 year after the procedure.

    Changes in plaque volume will be measured by CCTA at baseline and after 1 year. Optically derived signatures (OCT-NIRAF) obtained at baseline will be compared to changes in plaque volume.
