Inclusion criteria

1. Male or non-pregnant female patients 18 years of age 2. Diagnosis of angina pectoris as defined by Canadian Cardiovascular Society Classification (CCS I, II, III, IV) OR unstable angina pectoris (Braunwald Classification B&C, I-II) OR patients with documented silent ischemia; 3. Treatment of a single de novo target lesion in a major native coronary artery; 4. Target lesion is 2.5 mm and 3.5 mm in diameter (visual estimate); 5. Target lesion is 30mm in length (visual estimate); 6. Target lesion stenosis is \> 50% and \< 100% (visual estimate);

Exclusion criteria

1. Patient has experienced a Q-wave or non-Q-wave myocardial infarction with documented total CK \> 2 times normal within the preceding 24 hours and the CK and CK-MB enzymes remain above normal at the time of treatment; 2. Has unstable angina classified as Braunwald III B or C, or is having a peri-infarction angina; 3. Significant (\> 50%) stenoses proximal or distal to the target lesion that might require revascularization or impede runoff; 4. Documented Left ventricular ejection fraction 25%; 5. Totally occluded vessel (TIMI 0 level); 6. Impaired renal function (creatinine \> 3.0 mg/dl) at the time of treatment;
