Some medical conditions and treatments put you at risk for a pulmonary embolism, such as:
*Heart disease. Heart and blood vessel disease, specifically heart failure, makes clot formation more likely.
*Cancer. Certain cancers — especially brain, ovary, pancreas, colon, stomach, lung and kidney cancers, and cancers that have spread — can increase the risk of blood clots. Chemotherapy further increases the risk. You also have a higher risk of blood clots if you have a personal or family history of breast cancer and are taking tamoxifen or raloxifene (Evista).
*Surgery. Surgery is one of the leading causes of problem blood clots. For this reason, medicine to prevent clots may be given before and after major surgery, such as joint replacement.
*Disorders that affect clotting. Some inherited disorders affect blood, making it more likely to clot. Other medical disorders such as kidney disease also can increase the risk of blood clots.
*Coronavirus disease 2019 (COVID-19). People who have severe symptoms of COVID-19 have an increased risk of pulmonary embolism.
