Venous thromboembolism (VTE) refers to deep vein thrombosis (DVT) and pulmonary embolism (PE). VTE ranks among the top five most common vascular diseases in most countries. VTE is associated with a high risk of mortality (an estimated 20% of patients die within one year of diagnosis). Mortality is caused by either the VTE event or the disease/condition that provoked the event. Fortunately, VTE is preventable.
