Patient description: The patient is a 42 year-old postmenopausal woman who had a screening sonogram which revealed an abnormality in the right breast. She had no palpable masses on breast exam. Core biopsy was done and revealed a 1.8 cm infiltrating ductal breast carcinoma in the left upper outer quadrant. Lumpectomy was done and the surgical margins were clear. The tumor was HER2-positive and ER/PR negative. Axillary sampling revealed 1 positive lymph node out of 12 sampled. CXR was unremarkable. She is using “well women” multivitamins daily and no other medication. She smokes frequently and consumes alcohol occasionally. She is in a relation with only one partner and has a history of 3 pregnancies and live births. She breastfed all three children.

Clinical trial eligibility criteria: eligible ages (years): 18.0-999.0,  Coronary Artery Stenosis Age ≥ 18 years Patient with an indication for PCI including angina (stable or unstable), silent ischemia (in absence of symptoms a visually estimated target lesion diameter stenosis of ≥70%, a positive non-invasive stress test, or FFR ≤0.80 must be present), or recent STEMI. For STEMI the time of presentation to the first treating hospital, whether a transfer facility or the study hospital, must be >24 hours prior to randomization and enzyme levels (CK-MB or Troponin) demonstrating that either or both enzyme levels have peaked Non-target vessel PCI are allowed prior to randomization depending on the time interval and conditions as follows: a. During Baseline Procedure: i. PCI of non-target vessels performed during the baseline procedure itself immediately prior to randomization if successful and uncomplicated defined as: <50% visually estimated residual diameter stenosis, TIMI Grade 3 flow, no dissection ≥ NHLBI type C, no perforation, no persistent ST segment changes, no prolonged chest pain, no TIMI major or BARC type 3 bleeding. b. Less than 24 hours prior to Baseline Procedure: i. Not allowed (see #3). c. 24 hours-30 days prior to Baseline Procedure: i. PCI of non-target vessels 24 hours to 30 days prior to randomization if successful and uncomplicated as defined above. ii. In addition, in cases where non-target lesion PCI has occurred 24-72 hours prior to the baseline procedure, at least 2 sets of cardiac biomarkers must be drawn at least 6 and 12 hours after the non-target vessel PCI. If cardiac biomarkers are initially elevated above the local laboratory upper limit of normal, serial measurements must demonstrate that the biomarkers are falling. d. Over 30 days prior to Baseline Procedure: iii. PCI of non-target vessels performed greater than 30 days prior to procedure whether or not successful and uncomplicated Patient or legal guardian is willing and able to provide informed written consent and comply with follow-up visits and testing schedule. Angiographic (visual estimate) Treatment of up to three de novo target lesions, maximum of one de novo target lesion per vessel Target lesion(s) must be located in a native coronary artery with visually estimated diameter of ≥2.5 mm to ≤4.25 mm and diameter stenosis ≥50% to <100% Lesion must be ≤28 mm long and can be covered by a single study stent with maximum length of 33 mm (note: multiple focal stenoses may be considered as a single lesion and be enrolled if they can be completely covered with one stent) TIMI flow 2 or 3 If more than one target lesion will be treated, the RVD and lesion length of each must meet the above criteria  Planned procedures after the baseline procedure in either the target or non-target vessels STEMI within 24 hours of initial time of presentation to the first treating hospital, whether at a transfer facility or the study hospital or in whom enzyme levels (either CK-MB or Troponin)have not peaked PCI within the 24 hours preceding the baseline procedure and randomization Non-target lesion PCI in the target vessel within 12 months of the baseline procedure History of stent thrombosis Cardiogenic shock (defined as persistent hypotension (systolic blood pressure <90 mm/Hg for more than 30 minutes) or requiring pressors or hemodynamic support, including IABP Known LVEF <30% Subject is intubated Relative or absolute contraindication to DAPT for 12 months (including planned surgeries that cannot be delayed, or subject is indicated for chronic oral anticoagulant treatment) Hemoglobin <10 g/dL
