Detailed Description:

Patients with acute coronary syndrome (myocardial infarction or unstable angina) who will undergo PCI and have at least one atherosclerotic lesion of >25% stenosis other than culprit lesions of current ACS are enrolled. Fibrous cap thickness of a target coronary plaque is evaluated by optical coherence tomography.


Ages Eligible for Study:   20 Years to 75 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Patients with acute coronary syndrome (myocardial infarction or unstable angina) who will undergo PCI.
  • plasma LDL cholesterol levels : >=100mg/dL and ≤160mg/dL
  • at least one atherosclerotic lesion of >25% stenosis other than culprit lesions of current ACS

Exclusion Criteria:

  • Patients who will undergo coronary bypass surgery.
  • Patients with major complications during treatment of culprit coronary lesions.
  • Patients with an atherosclerotic lesion with >50% stenosis at a left main trunk.
