Fixx had a huge family history of familial elevation of cholesterol with a father that had a heart attack
I've acknowledged that and IIRC, he also lost a brother to a heart attack at a young age.
I can't link to a source that corroborates my comments relative to the kneeling position, however, in my 30 years of running I've read more than a few times that's what happened.
The theory is that the heart attack damaged his heart to the point it wasn't able to overcome gravity and pump blood from his lower body back through his heart, the brain, lungs, etc. Had he been face down, there would be no gravity to overcome and he might have survived.

It really doesn't work that way. Just to let you know. Heart attack causes death by several mechanisms and positional death is not one of them. here's a brief primer..

That info is incorrect. Just telling you in order that in case of chest pain the paramedics don't find you ass up and face in the dirt. Embarrassing.

Just take an aspirin, wait for the paramedics and get to a hospital that is a "heart center". They'll have a protocol for getting you from door to cardiac catheterization and open coronary arteries in less than 60 minutes.
