In a COMPASS study (Cardiovascular Outcomes for People Using Anticoagulation Strategies), taking 100mg of aspirin and 2.5mg of rivaroxaban twice daily demonstrated that the risk of myocardial infarction or stroke was significantly reduced. Cardiovascular mortality and all-cause mortality were also reduced. In patients with diabetes who have a higher risk of mortality, their absolute risk reduction is three times lower than in patients without diabetes.
