RIETE: Understanding Venous Thromboembolism

This study, called RIETE (Computerized Registry of Patients with Venous Thromboembolism), is collecting information from many patients who have experienced venous thromboembolism (VTE), which includes deep-vein thrombosis (blood clots in deep veins), pulmonary embolism (blood clots in the lungs), or superficial venous thrombosis (blood clots in veins close to the skin). The goal is to learn more about how VTE affects different types of patients, especially those who aren't usually included in standard research studies, like pregnant women or those with cancer. By gathering this information, doctors hope to improve care, reduce deaths, prevent future blood clots, and lessen bleeding complications. You can join if you have a confirmed VTE and agree to participate. The study will track VTE events and complications for 3 years.
