Title: Effect of Dipyridamole Plus Aspirin on Hemodialysis Graft Patency
Brief Summary: The objective of the study is to determine whether Aggrenox (Boehringer-Ingelheim) prolongs primary unassisted patency in newly created arteriovenous grafts. This record previously included information for both the GRAFT and FISTULA trials.

A: Inclusion Criteria:

- Must not be of child-bearing potential (1 year post-menopausal, contraceptive or surgically sterile).

non-ST-segment elevation ACS defined by the presence of at least 2 of the following criteria: (1) symptoms of myocardial ischemia, (2) electrocardiographic ST-segment abnormalities (depression or transient elevation of at least 0.1 mV) or T-wave inversion in at least in 2 contiguous leads, or (3) an elevated cardiac troponin value (above the upper limit of normal) (2) or ST segment elevation ACS scheduled for primary PCI defined (22)as a history of chest discomfort or ischemic symptoms of \>20 minutes duration at rest ≤14 days prior to entry into the study with one of the following present on at least one ECG prior to randomization:

1. ST-segment elevation ≥1 mm in two or more contiguous ECG leads.
2. New or presumably new left bundle branch block (LBBB).
3. ST-segment depression ≥1 mm in two anterior precordial leads (V1 through V4) with clinical history and evidence suggestive of true posterior infarction

   * Subject intended for an invasive strategy if NSTE-ACS or primary PCI if STE-ACS according to guidelines (annexe 1)
   * Subject CKD stage 4 and 5 (estimated glomerular filtration rate (eGFR) \<30 ml/min/1.73 m2 by (MDRD formula) or undergoing chronic dialysis
   * Must be enrolled at a cardiac catheterization laboratory hospital or at a hospital/ambulance service affiliated with a cardiac catheterization laboratory hospital.
   * Subject affiliated to or beneficiary of a social security system.
   * Subject having signed written informed consent.

Exclusion Criteria:

* Minors, pregnant or breast-feeding women;

* Subject with bleeding ;

B: Inclusion Criteria:

1. Males or females ≥ 18 years of age with coronary artery disease with low, intermediate or high-risk coronary anatomy, which is considered suitable for PCI with stent placement.
2. Subjects who have provided written informed consent prior to initiation of any study-related procedures, prior to receiving any pre-procedural sedation and who agree to comply with all protocol-specified procedures.

Exclusion Criteria:

1. Women who are pregnant. Women of childbearing potential must have a negative pregnancy test (urine or serum HCG) within 7 days prior to randomization; as close to randomization as possible, within 24 hours preferred.
2. Allergy or intolerance to aspirin, or both clopidogrel and ticlopidine
3. Subjects with a contraindication to anticoagulation and/or increased bleeding risk:

   * Past or present bleeding disorder including a history of the following within 1 month prior to randomization: clinically relevant gastrointestinal bleeding, gross (visible) hematuria,
   * Planned major surgery including CABG after or within 1 month prior to randomization.
   * Any subject with a known coagulopathy, platelet disorder, or history of thrombocytopenia.
4. Subjects with a history of cancer (limiting survival) not known to be disease free, with the exception of basal cell carcinoma of the skin.
5. History of clinically important, recent or ongoing alcohol abuse or other drug abuse.
6. Known platelet count \<100,000/mm3 (\<100 x 109/L).
7. Subjects who is unable to give informed consent and assurance for complete contact through 2 years.
C: Inclusion criteria:

* Age 18-21 depending on state regulations
* Life expectancy of at least six months
* Chronic renal failure with anticipated start of hemodialysis within six months of enrollment, or current dialysis dependence
* A new or planned arteriovenous (AV) graft placed in any location for the purpose of hemodialysis. (Any type of graft material and any configuration of the access is acceptable).
* The patient is expected to stay at a participating dialysis facility for at least 6 months.
* The patient's physician(s) will allow the patient to participate.
* Ability to give informed consent.

Exclusion Criteria:

* Women must not be pregnant, breastfeeding, or plan to be pregnant during the course of the study.
* The presence of ongoing bleeding.
* The presence of a known bleeding disorder (e.g., hemophilia or von Willebrand's disease).
* Recent bleeding episode requiring transfusion within 12 weeks of entry.
* The presence of acute ulcer disease. Acute ulcer disease is defined as a new diagnosis of peptic disease including esophagitis, gastritis, or ulcer or the initiation of treatment with proton pump inhibitors, H2 blockers or therapy for Helicobacter pylori within three months prior to obtaining consent.
* Known allergy or adverse reaction to Aggrenox or any of its study components (dipyridamole and aspirin).
* Required use of warfarin, dipyridamole, non-steroidal antiinflammatory drugs or other antiplatelet agents other than aspirin.
* Current uncontrolled hypertension with systolic blood pressure in excess of 200 mm Hg or diastolic blood pressure in excess of 115 mm Hg.
* Baseline platelet count less than 75,000/mm3.
* Known advanced liver disease with decompensated cirrhosis, jaundice, ascites or bleeding varices.
* Current problem with substance abuse.
* Concurrent participation in another medical intervention trial.
* Anticipated non-compliance with medical care based on physician judgment.
* Patient refusal.
