Coronary: A True Story of Medicine Gone Awry Book

The first 50 pages are a bit slow, but then the pace picks up as one learns that over 1000 people in Redding CA had unneeded triple/quadruple bypass surgery because of the greed of a few doctors and a hospital chain.

The people in this small town at some level knew that something was amiss.
They told each other a number of jokes like:
"Don't have an accident in front of the hospital or you'll come out with a zipper in your chest."

But they were proud of the fact that their hospital was considered a major cardiac center, and that it created so many jobs.
This pride and greed caused them to not look too closely at what was really going on.

Several people died as a result of this unneeded surgery, but no one went to prison for it.

An interesting mix of whistleblowing, investigation, medicine and law.
Naturally the lawyers made several hundred million $ or so.
And for not much work, because no cases went to trial,
it was all settled over the phone or a cup of coffee.
