"If you're among the hundreds of thousands of Americans with clogged kidney arteries, you might want to consider trying medicines before rushing into angioplasty to open them up. The pricey procedure is no more effective and carries surprisingly big risks, a study found.Still think they have any idea what they are talking about?
The National Kidney Foundation estimates more than 250,000 Americans have narrowing of the arteries that supply blood to the kidneys. It's usually caused by a buildup of fatty plaque, mostly in folks 50 or older, and can result in high blood pressure and, sometimes, kidney failure. Each year, about one in six patients with the condition dies.
About 16 percent of patients with newly diagnosed blockages in kidney blood vessels undergo angioplasty or, occasionally, more-invasive artery bypass surgery. But rushing to get blood vessels cleaned out could be a dangerous mistake, according to a British study and some experts.
Doctors at several British hospitals and universities compared patients with severe kidney artery blockages who were treated just with medicines with a group that got the same drugs and underwent angioplasty, in which a catheter is threaded through an artery to clear out blockages. The angioplasty group fared no better — and some of those patients suffered serious complications, including deaths and amputations."

The shelf life of "truth" is very short in the domains of fitness, health and well-being.
The reason is that so much of what we are told is "true" is really baseless.
