The article itself is somewhat informative, but can be found elsewhere via Google for free. amazon.com is the real problem not putting the article in my digital box for days despite multiple complaints and requests. There is no procedure for getting a refund even though amazon claims there is. Nor was a refund request via e-mail honored.As to the content of the article, both pro and con have legitimate statements to make, but let's face it, stents are putting surgeons out of business more and more.
