Registry of Patients Prescribed Anticoagulation for VTE

This study is a registry, which means it collects information from routine medical care, for patients who are prescribed blood thinners (anticoagulation) after being diagnosed with a blood clot (venous thromboembolism or VTE). This includes deep vein thrombosis (DVT) or pulmonary embolism (PE). You can join if you are 18 or older and start anticoagulation treatment within 14 days of your VTE diagnosis at the Mayo Clinic's Thrombophilia Clinic in Rochester, Minnesota. You cannot join if you are already taking blood thinners for other reasons or are in another blood thinner clinical trial. The study aims to track how often patients experience another blood clot or major bleeding over 10 years.

Study design
