Dutch rivaroxaban CCS registry

The Dutch rivaroxaban CCS registry is a study which investigates the impact in terms of effectiveness and safety of the combination treatment of rivaroxaban 2.5 mg twice daily with aspirin on clinical outcomes and practices in a real-life Dutch patient population that are at high risk of ischemic events.
