An international research team with prominent Canadian leadership has found that the blood thinner rivaroxaban is as safe as aspirin, and more effective at preventing recurrence of life-threatening blood clots in the legs and lungs, according to a study published in the New England Journal of Medicine.

Venous thromboembolism is a chronic disease, with risks of additional blood clots over a patient’s lifetime.
