What Causes Pulmonary Embolism While Being On Warfarin?

Hi, my husband just had a pulmonary embolism a few days ago.He is now home and on warfarin.Is there a risk while on treatment to have another blood clot? We were lucky to go to the hospital and get diagnosed but living in fear now that he can have another one that can maybe cause sudden death.

Hi,
Thanks for asking.
Based on your query, my opinion is as follows.
1. Warfarin is given to reduce risk of future thrombosis.
2. Once a patient suffers from pulmonary embolism, future risk of thrombus formation needs to be reduced. Warfarin therapy with maintenance of INR with 2-3 range needs to be done.
3. Once on warfarin therapy, risk of thrombus formation and pulmonary embolism is low. However, bleeding is a possible risk.
4. Need to be regular on warfarin therapy. Pulmonary thromboembolism formation possibility is completely reduced and similar to normal population.
Hope it helps.
Any further queries, happy to help again.
