Prospective, multi-center, randomized 1:1, single blind trial using BuMA Supreme versus Resolute Integrity conducted in approximately 14 interventional cardiology centers in The Netherlands, Belgium, Spain and Portugal.

Clinical follow-up will occur at 1, 9 and 12 months post-stent implantation. All patients will undergo repeat angiography at 9 months follow-up. QCA assessment will be performed at baseline (pre- and post-procedure) and at 9 months follow-up.

Inclusion Criteria:

1. The subject is at least 18 years of age.
2. Clinical evidence of ischemic heart disease and/or a positive territorial functional study.
3. Documented stable angina pectoris (Canadian Cardiovascular Society (CCS) Classification 1, 2, 3 or 4) or unstable angina pectoris with documented ischemia (Braunwald Class IB-C, IIB-C, or IIIB-C), or documented silent ischemia
4. The patient has a planned intervention of a single de-novo lesion in one or two separate major epicardial territories (LAD, LCX or RCA).
5. Diameter Stenosis≥50 and<100%.
6. The visually estimated target lesion must be able to be covered by a single BuMA Supreme stent or a single Resolute Integrity stent (for available sizes refer to tables 1 and 2, page 20 and 21).
7. The target lesion reference diameter must be visually estimated to be ≥2.5 mm and ≤4.5 mm in diameter.
8. Written informed consent.
9. The patient agrees to the follow-up visits including a 9 month angiographic follow-up.
10. Patient must have completed the follow-up phase of any previous study.

Exclusion Criteria:

1. Female of child bearing potential (age <50 years and last menstruation within the last 12 months). Subjects with age <50 who underwent tubal ligation, ovariectomy or hysterectomy can be included.
2. Evidence of ongoing acute myocardial infarction (AMI) in ECG and/or elevated cardiac biomarkers (according to local standard hospital practice) have not returned within normal limits at the time of procedure
3. Patient suffered from stroke/TIA during the last 6 months.
4. LVEF <30%
5. Platelet count <100,000 cells/mm3 or >400,000 cells/mm3, a WBC of <3,000 cells/mm3, or documented or suspected liver disease (including laboratory evidence of hepatitis)
6. Known renal insufficiency (e.g. serum creatinine >2.5mg/dL, or creatinine clearance ≤30 mL/min), or subject on dialysis, or acute kidney failure (as per physician judgment).
7. Patient undergoing planned surgery within 6 months with the necessity to stop DAPT.
8. Patient requiring oral anticoagulation (Coumadin, Novel Oral Anticoagulant (NOAC))
9. History of bleeding diathesis or coagulopathy
10. The patient is a recipient of a heart transplant
11. Known hypersensitivity or contraindication to aspirin, heparin, antiplatelet medication specified for use in the study, sirolimus, zotarolimus, or cobalt-chromium.
12. Other medical illness (e.g. cancer, stroke with neurological deficiency) or known history of substance abuse (alcohol, cocaine, heroin etc.) as per physician judgment that may cause non-compliance with the protocol or confound the data interpretation or is associated with a limited life expectancy
13. The patient is simultaneously participating in another investigational device or drug study
