My 88 1/2 year old father was diagnosed about 3 weeks ago with a pulmonary embolism. He was on coumadin, (sp?), for about 3-4 years then went off of it in late January/early February, and, even with this diagnosis, does not want to return to it. He lives in a wonderful assisted living community, does not smoke and is not over weight at all. Fully aware that all situations are different, is there any kind of forecast you would be willing to share as far as what to expect as far as his quality of life and life expectancy? Thank you!
