Such political handicapping will increase if the Vice President makes additional trips--planned or not--to the hospital. There's a risk that the coronary artery that was propped open with a stent in November and then cleared of a buildup of tissue in March, could become blocked again. And there's also a remote possibility that if the defibrillator is repeatedly activated, doctors will opt to destroy the troublesome section of scar tissue that's throwing off Cheney's heart rhythm. That would require yet another trip to the hospital and another round of spin doctoring. But if last...
...probably is almost routine by now. Once more through the chart: This is the vice president's third hospitalization since the election. He had his first heart attack in 1978, quadruple bypass surgery in 1988, and his latest, fourth heart attack in November (complete with wire stent to open a 90-percent-blocked artery...
Furthermore, it wasn't atherosclerosis or a heart attack that sent Cheney to the hospital. Rather, scar tissue had formed around the wire-mesh stent that was implanted last November to open a blocked coronary artery. This had led to a renarrowing, or restenosis, of the vessel. (Restenosis occurs in 20% of such cases.) Although one study suggests that "burnout" can trigger restenosis, the evidence is hardly conclusive and in any case doesn't apply to Cheney, who obviously relishes his job. "If you have a job you love, then you're lucky," says Dr. Alan Wasserman, chief of medicine...
Doctors found that scar tissue had developed around the artery support structure, known as a stent, used in the November angioplasty, and blockage in the artery had returned to 90 percent of its original severity...
GLOWING REPORT The great thing about opening a clogged artery with angioplasty--and keeping it open with a tiny stent--is that the treatment works 90% of the time. In the short term, at least. After six months the artery closes back up again in 1 patient out of 4. Now scientists have come up with a hot new idea: blast the treated vessel, stent and all, with radiation. Two preliminary studies suggest that the odds a zapped vessel will reclog are reduced as much...
