To Evaluate The Efficacy And Safety Of Rivaroxaban In Combination With Aspirin Compared With Aspirin Monotherapy In Patients With Stable Coronary Artery Disease (CAD) and High Ischemic Risk

November 4, 2026 updated by: Republican Specialized Scientific and Practical Medical Center of Cardiology

This study compares rivaroxaban plus aspirin with aspirin alone in patients with stable coronary artery disease at high ischemic risk. The aim is to evaluate whether the combination therapy better prevents cardiovascular events and to assess its safety.

Detailed Description

This study will compare the effectiveness and safety of rivaroxaban plus aspirin versus aspirin alone in patients with stable coronary artery disease who are at high risk of ischemic events. Participants will be randomly assigned to receive either rivaroxaban combined with aspirin or aspirin alone. The main goal is to determine whether the combination of rivaroxaban and aspirin reduces the risk of cardiovascular events (such as heart attack, stroke, or cardiovascular death) more effectively than aspirin monotherapy, while also assessing bleeding risks and overall safety.
