- Date Registered NTR6-jul-2016
- Secondary IDsNL54577.078.16 
- Public TitleThe Rotterdam Antiplatelet Therapy in Vascular Patients Study
- Scientific TitleThe Rotterdam Antiplatelet Therapy in Vascular Patients Study
- ACRONYMRAVE
- hypothesisLong-term mortality after vascular surgery in high-risk patients can be explained through atherothrombotic events en therefore be treated with adequate antithrombotic therapy.
- Healt Condition(s) or Problem(s) studiedAbdominal Aortic Aneurysm, Peripheral Arterial Disease, Myocardial ischemia
- Inclusion criteria1. Preoperative myocardial injury (baseline value), defined as hsTnT release > 14 ng/L.
2. Absence of significant occlusive coronary artery disease as diagnosed through angiography (and confirmed by FFR).
3. Postoperative myocardial injury, defined as hsTnT release > 14 ng/L, which exceed the baseline value.
- Exclusion criteriaPotential subjects will be excluded with any of the following;
1. If event (i.e. hsTnT elevation) is diagnosed as myocardial infarction by cardiologist.
2. Presence of significant occlusive coronary artery disease, as diagnosed through preoperative angiography, requiring treatment.
3. No postoperative hsTnT values above the clinical reference of 14 ng/L and no rise with respect to baseline value.
4. Active bleeding.
5. Active cardiac conditions at the time of randomization such as unstable angina pectoris, active congestive heart failure (CHF), serious cardiac arrhythmias, symptomatic valvular disease.
6. Clear indication for long-term P2Y12 inhibitor use.
7. Preoperative use of P2Y12 inhibitors.
8. Previous allergy or intolerance to clopidogrel.
9. Use of oral anticoagulants after surgery.
10. Use of intravenous glycoprotein IIB/IIIA receptor inhibitors in the previous three days.
11. Coronary revascularization therapy in the previous six months.
12. Renal failure requiring dialysis.
13. Significant liver disease (i.e. ALAT, ASAT > 3x ULN).
14. Cancer with an expected life expectancy less than 6 months.
15. Excessive alcohol use.
16. No informed consent.

- Target number of participants100
- InterventionsClopidogrel or placebo on top of standard treatment with aspirin
- Primary outcomeThe primary objective is to assess the efficacy of clopidogrel, as compared to placebo, on top of standard treatment with aspirin on;
A. the composite endpoint of MACE, defined as;
- cardiovascular death
- non-fatal myocardial infarction
- stroke
- severe ischemia of the coronary or peripheral arterial circulation leading to intervention
- Secondary outcomeSecondary objectives include determining the efficacy of clopidogrel, compared to placebo, on top of standard treatment with aspirin on;
B. Individual components of MACE
C. Safety of clopidogrel, in terms of bleeding complications, defined as life-threatening bleeding, moderate and minor bleeding, postoperatively and during long-term follow-up.

Tertiary objectives include determining;
D. Presence of significant coronary artery disease and the impact of presence of vulnerable plaques according to PROSPECT criteria
