Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Longterm oral anticoagulation with very low dose rivaroxaban (2.5mg bid) in combination with aspirin has been shown superior over standard aspirin monotherapy in patients with stable coronary artery disease (CAD) in the COMPASS trial. To date, there are no data comparing these - antithrombotic strategies and to provide insights about mechanistic effects of very low dose rivaroxaban on top of aspirin for longterm treatment.

Thus, the goal of the planned pilot study will be to identify effects of rivaroxaban on platelet function, platelet-mediated vascular inflammation and particularly, platelet-mediated thrombin generation as well as the underlying mechanisms and to reveal differences in mechanistic effects during longterm treatment with combined novel antiplatelet/anticoagulant strategies. This study is planned as descriptive study.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Stable coronary and peripheral artery disease (CAD/PAD)

Stable CAD/PAD patients with previous percutaneous coronary intervention and drug eluting stent-implantation treated with dual antiplatelet therapy (ASA+clopidogrel)

Rivaroxaban

Intervention Type DIAGNOSTIC_TEST

In stable CAD/PAD patients with previous PCI and DES-implantation treated with DAPT (ASA+clopidogrel) platelet rich plasma (PRP) and washed platelets as well as serum/plasma/urinary samples will be collected between 2 and 4 weeks before switching from DAPT to ASA + rivaroxaban (2,5 mg b.i.d.), between 2 and 4 weeks under monotherapy with ASA 100mg o.d., and between 2 and 4 weeks under therapy with ASA 100mg o.d. + rivaroxaban (2,5 mg b.i.d.) and treated ex vivo with rivaroxaban to asses platelet activation and function, platelet-triggered thrombin generation and platelet-dependent vascular inflammation.

Acute coronary artery disease (ACS)

Patients with troponin-positive ACS (NSTEMI/STEMI) with planned percutaneous coronary intervention and drug eluting stent-implantation treated with P2Y12 inhibitor (ticagrelor) and ASA

Rivaroxaban

Intervention Type DIAGNOSTIC_TEST

In stable CAD/PAD patients with previous PCI and DES-implantation treated with DAPT (ASA+clopidogrel) platelet rich plasma (PRP) and washed platelets as well as serum/plasma/urinary samples will be collected between 2 and 4 weeks before switching from DAPT to ASA + rivaroxaban (2,5 mg b.i.d.), between 2 and 4 weeks under monotherapy with ASA 100mg o.d., and between 2 and 4 weeks under therapy with ASA 100mg o.d. + rivaroxaban (2,5 mg b.i.d.) and treated ex vivo with rivaroxaban to asses platelet activation and function, platelet-triggered thrombin generation and platelet-dependent vascular inflammation.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. patients≥ 18 years.
2. troponin-positive acute coronary syndrome (NSTEMI/STEMI) with planned dual antiplatelet therapy (DAPT, ASA + ticagrelor) for 12 months or stable CAD with previous PCI and drug eluting-stent (DES) + pre-existing PAD under treatment with DAPT (ASA + clopidogrel).
3. Patients with coronary artery disease who are younger than 65 years of age are required to have documentation of atherosclerosis involving at least two vascular beds or to have at least two additional risk factors (current smoking, diabetes mellitus, an estimated glomerular filtration rate \[GFR\] \<60 ml per minute, heart failure, or nonlacunar ischemic stroke ≥1 month earlier).
4. informed written consent.

Exclusion Criteria
