Pulmonary Embolism Support Group
By far the most common form of pulmonary embolism is a thromboembolism, which occurs when a blood clot, generally a venous thrombus, becomes dislodged from its site of formation and embolizes to the arterial blood supply of one of the lungs. Symptoms may include difficulty breathing, pain during breathing, and more rarely circulatory instability and death.
The major thing I remember is the company we were looking at asked about several things specifically (asthma, diabetes, etc.) but didn't have a spot for "other" so it'd be possible to get coverage without really mentioning that I'm a lifer.
I think you just have to get the forms and look through them to see what they have to know for you to get coverage. I imagine that all of them are different in the information they request.
