2 or 3 Heart attack’s already by then
The writing was on the wall & he chose to go full bore and ignore it.
If the rumours were correct.
Jeez way to go Greg.
On December 3rd of 2000, Greg came to my city of Thunder Bay, Canada [which is in the province of Ontario, where Greg was born and raised, and I lived in until his death], and my friend told me that Greg had allegedly suffered, as you quoted, 2-3 heart attacks.
I have no idea if that was true. When he came to Thunder Bay, he was tipping the scales just north of 400-lb. He may have been around 410, something like that.
On Canada's "MUSCLE INSIDER" magazine's website, Greg stated that he was 365-lb in 2012, just under two years before he died. On a radio/podcast interview with Dave Palumbo, Greg also stated that if he had it is way, he would just train for fun, and weigh around 400-lb.
So clearly, he enjoyed being 400-lb at 25% body fat, or whatever percentage he was at, despite the pain that came with it.
Given that Greg died in 2013 and was 365-lb in 2012, I think that it is safe to say that he was likely around 365-lb when he passed away. Here is the MUSCLE INSIDER article where he stated that his max weight was 412-lb:

That must have played on his Bigorexia a lot.
Tony Doherty - long time promoter of the Australia Pro Show - stated that Greg was quite insecure. The stories were sad.
I think we can most likely state with confidence that Greg weighed over 400-lb between 1995-2005, and that even going back as far as Greg's 19th birthday in December of 1987, he was almost surely around 290-lb and ripped.
Greg was likely over 300-lb from 1986-2013 [aside from early contests that Greg competed in between 1989-1994, where he cut down to as light as 270-lb, literally at the very lightest, and that would have only been in 1989-1990].
Think about that:
Greg spent 27 of his [just under] 45 years of life weighing over 300-lb.
Greg spent around 10 of those 27 years weighing over 400-lb.The latter fact is probably the most significant one to think about when considering the toll on his cardiovascular system - between 1995-2005, aside from the four contests he competed in [turning pro in 1996, then the 1997 NOC, and both the 1998/2001 Ironman contests, the last of which he dropped out of], Greg was consistently 400-lb or more at 6'2.
For some appearances, he may have weighed a little less, but even at those times, he would have been taxing his body by using cutting agents to lose weight.
All this considered, Greg led a unique, but in my opinion, ultimately sad life.
Here is a video I did showing some rare photos of Greg, posted by his sister on her Facebook page, tagged with Greg's name:
