I'm not a cardiologist but I've never heard of performing Cardiac stress tests as a routine screening in a 44 year old with no serious history of heart disease and no cardiac symptoms. Maybe if Vinman was a couch potato and told his doc he was going to train for a marathon or something.
I wonder if Vinman's doc happens to own the stress testing center.
Read this book. It's a true story and I knew some of the players. It will scare the crap out of you.
