An estimated 1.2 million Americans are discharged from a hospital with a diagnosis of acute coronary syndrome (ACS) each year. Now, a new randomized controlled trial dubbed "ATLAS ACS 2" (Anti-Xa Therapy to Lower Cardiovascular Events in Addition to aspirin with/without thienopyridine therapy in Subjects with Acute Coronary Syndrome), is suggesting rivaroxaban may reduce the risk of the composite end point of death from cardiovascular causes, myocardial infarction, or stroke in patients with a recent ACS, but at a cost of increased major bleeding.
