Intra-stent Tissue Evaluation Within BMS and DES > 3 Years Since Implantation

This study aims to test the hypothesis that plaque composition differs within a stent between bare metal stents and drug eluting stents (DES). It is possible that a difference in plaque composition seen within a stent may be contributory to the late thrombotic events seen more frequently with DES.

A total of 40 subjects will be enrolled in the study, with 20 patients who previously received BMS > 3 years ago and 20 patients who previously received DES > 3 years ago
- Subject > 18 years of age;
- Subject, male or female, who underwent DES or BMS implantation in a native coronary vessel more than 3 year ago;
- Subject is scheduled for a diagnostic coronary or interventional procedure;
- Subject is willing to sign the informed consent.
- Subject requires emergency catheterization;
- Subject has an acute myocardial infarction defined as anginal symptoms with ST-elevation on the EKG or creatine kinase-MB elevation >3times the upper limit of normal;
- Angiographic evidence of ≥ 70% stenosis within the target stent (visual estimate);
- Subject presented with cardiogenic shock;
- Subject has angiographically confirmed thrombus in the target coronary artery;
- Subject has a complex lesion not amenable to the IVUS/VH catheters and/or OCT catheters passing the stented segment;
- Subject has a contraindication to angiography/IVUS/OCT;
- Female subject is pregnant or lactating;
- Subject has life threatening comorbid conditions for which the investigator feels the subject should not be enrolled
