Medical Conditions
Some health disorders or conditions can also cause blood to clot more easily, which might lead to pulmonary embolism. On the other hand, some treatments like medications or surgeries for medical conditions can also lead to blood clot formation. Chemotherapy for cancer patients can also happen to form abnormal blood clots in the body which travel towards the lungs and result in the development of pulmonary embolism. A patient with a history of heart attack or stroke is also at a higher risk of getting pulmonary embolisms in comparison to other people.
