minority of patients with severe disease,bypass operations don't prolong life or prevent future heart attacks.Nor does angioplasty,in which narrowed vessels are expanded and then,typically,propped open with metal tubes called stents. "People often believe that having these procedures fixes the problem, as if a plumber came in and fixed the plumbing with a new piece of pipe," explains Dr.L.David Hillis,professor of cardiology at the University of Texas Southwestern Medical School."But it fundamentally doesn't fix the problem. With doctors doing about 400,000 bypass surgeries and 1 million angioplasties a year-part of a heart-surgery industry worth an estimated $100 billion a year-the question of whether these operations are over used has enormous medical and economic implications."It is one of the major issues in cardiology right now,"says Dr.David Waters,chief of cardiology at the university of Californiaat San Francisco It is also part of a far boarder problem-what some health-care experts call the medicalization of life."None of us will live long without headache,backache,heartache,heartburn,diarrhea,constipation,sadness, malaise,or other symptoms of some kind,"argues Hadler.Yet under relentless bombardment by messages from the pharmaceutical and health-care industries,Americans increasingly believe that these symptoms-and many others-are conditions that can and should be

As Hadler describes in his book,data from bypass-surgery clinical trials in the late 1970s show that the procedure extends life or prevents heart attacks only in a small percentage of patients-those with severe disease."The overwhelming number of heart procedures done these days do not affect patients'life spanat all,"says Hillis. The latest thinking on heart attacks may explain why not.In the traditional view,the slow accumulation ofplaque inside arteries gradually narrows and vessels.Reduced blood flow causes chest pain,or angina. Eventually the arteries are blocked,bringing on heart attacks.Newer evidence,however,pins the blame not on this gradual narrowing but on unstable plaque that breaks off and causes clots.The clots are what obstruct the arteries,causing the heart attacks-which is why so many such events are unexpected and why "there is no evidence that opening chronically narrowed arteries reduces the risk of heart attack,"says Waters. The better way to lower heart attack risk is to fight the unstable plaque with aggressive cholesterol-reducing drug therapy,diet,and lifestyle changes,many cardiac physicians say.That can be a tough sell to patients who want a quick fix,says Hillis."Medical therapy is just not as sexy as doing a procedure,"he explains."The assumption our society makes is that the more aggressive your medical care is,the better it is.It's not true.But if I explain to a patient why he doesn't need surgery,9 times
