Regardless of how well Cheney fields reporters' questions or waves to the cameras, he can't erase a history of four heart attacks, one quadruple-bypass surgery and a coronary artery propped open with a metal stent--all over a 22-year period in a man considered far too young to have suffered so many setbacks...
...reassuring performance, but it wasn't exactly the straight story. In fact, Cheney had suffered what his doctors belatedly described as a mild heart attack, though Bush almost certainly didn't know that when he appeared before the cameras. Cheney had just undergone a surgical procedure to insert a stent, a steel mesh cylinder that expands to pry open a clogged artery. A Bush aide, Dan Bartlett, said later that Bush knew the procedure had taken place but did not tell the public because he did not feel equipped to discuss it. And anyway, he wanted to focus...
...registers within the 50% to 70% range. Cheney's is a serviceable 40%. His cardiologist, Dr. Jonathan Reiner, called that a sign of moderate impairment. Cheney's doctors also announced that for 30 days Cheney will take a blood thinner, Plavix, to prevent blood clots from forming around the stent before it can be covered by the growth of new tissue...
...next step was to thread a tiny surgical balloon and a thin stainless-steel stent into the artery to forcibly widen the passage. After the balloon was deflated, the metal mesh of the stent was left in place to keep the artery open. During this procedure the results from Cheney's second blood test became available. It showed a slight increase in the cardiac enzymes, indicating that Cheney had suffered a mild heart attack after...
