Study Status: 
Study Description: 

This clinical trial is for men and women who will undergo coronary angiography,  a minimally invasive catheter-based procedure to visualize the arteries that supply blood to the heart, whose procedure is likely to include IVUS (intravascular ultrasound imaging, which employs a miniaturized ultrasound probe attached to the catheter).

The purpose of this study is to determine whether detecting cholesterol-rich plaques in the coronary arteries using near-infrared light can predict future coronary problems for persons who have already experienced such problems. Study subjects will be followed up for 2 years after the coronary angiography procedure.

Key Eligibility: 

Men and women age 18 and older who will undergo coronary angiography including IVUS may enroll in the study if they have been diagnosed with one of the following conditions:

  • Acute coronary syndrome (ACS)
  • Unstable angina pectoris
  • Stable angina pectoris and/or a positive functional study with evidence of ischemia

Detailed eligibility requirements will be reviewed when you contact the study team.
