Difficulty breathing. The most common symptom is shortness of breath or difficulty breathing.
2 main reasons. 1. Massive pe can cause cardiovascular collapse / heart strain / arrhythmia 2. You can't oxygenate your blood (i.e. Oxygen enters your lungs but can't get into your blood because your pulmonary vessels are "clogged" with a large pe (or pes).
BLOOD SUPPLY STOPS. It can stop the blood supply to the heart and or lungs.
Heart. Unable to pump blood effectively and lungs unable to oxygenate blood effectively if embolism to pulmonary arteries is large enough.
My son, 35, avid walker, no genetic factors, no drugs, never sat down, didn't smoke, drink, died of a pulmonary thromboembolism caused by dvt?
DVT. I'm sorry for your loss. It is possible despite what you say. Was there a postmortem to be sure that was what happened?
I'm so sorry. My heart goes out to you--it certainly sounds like your son didn't have DVT risk factors, however pulmonary emboli can happen and almost anyone. Genetic factors can play a role. You may want to talk to a henatologist (blood doctor) about possible clotting problems in your family.
