I've followed news about stents for decades.
They're about $5,000 each.
A couple times per year there is some news report similar to this story.
I have a feeling that, just like hip replacements took decades to find the right combination of materials to not disintegrate or be rejected, we're still researching what to make stents from and when to use them.
The problem is that patients aren't told they're guinea pigs, and stents aren't that reliable. Oh and doctors get to bill a fortune per operation regardless.
Regarding this particular story, rather than be outraged, we should have cardiac experts and statisticians sit down and figure out what's real and what isn't. There is valuable data in there somewhere.
