A selection of talks on Haematology
Hello everyone, I'm Allyson Pishko from the University of Pennsylvania, and I'll be presenting on anticoagulation for venous thromboembolism.
The objectives for today's talk will be to review the indications for anticoagulation, then we will focus on a specific indication for anticoagulation - venous thromboembolism. We'll describe the phases of treatment of venous thromboembolism, then go on to describe the mechanisms of different anticoagulants. We will then develop a framework for determining the duration of anticoagulation for the treatment of venous thromboembolism.
Anticoagulants are popular medications as there are many indications for anticoagulation. This includes prevention or primary prophylaxis, which is stroke prevention and patients at high risk due to atrial fibrillation. It can be used for deep vein thrombosis prophylaxis in high-risk patients such as hospitalized patients or patients undergoing surgery. It is also a medication that is used in the treatment of acute DVT or pulmonary embolism, and also used in peripheral arterial disease. Anticoagulants can also be used for secondary prophylaxis, such as the prevention of recurrent VTE or recurrent stroke. This talk will focus on acute DVT or pulmonary embolism treatment with anticoagulants.
This is an important problem as venous thromboembolism, which includes pulmonary embolism and DVT, occurs commonly in the population. There are over 10 million cases of VTE diagnosed annually worldwide.
