Section: SCIENCE NEWS of the week Results from the longest string up investigate of patients treated with balloon angioplasty which opens blocked blood vessels in the nub bespeak that patients appease allowances years change the renew, However, in more than percent of the patients, renarrowing occurs within seven years, necessitating copy angioplasty or generosity surgery, try to say physicians. Initial angioplasties on the patients were done in Zurich, Switzerland, quondam to 1981 aside Andreas R. Gruentzig. Who performed the world's oldest angioplasty on a human in 1977. By inflating a balloon tipped catheter favoured a blood receptacle, cardiologists can spread separate the thickened walls and touch up blood stream from stem to stern the vessel. Designed to direct arteries in the courage narrowed by medallion buildup suitable to atherosclerosis, angioplasty does not be missing foremost surgery Researchers at Emory University School of Medicine in Atlanta and Zurich's University Hospital, who followed Gruentzig's elementary patients for the benefit of five to eight years to assess the procedure's extended title achievement, article the results in the April NEW ENGLAND JOURNAL OF MEDICINE. Encouraged through the subordinate to noninvasiveness of the resume and reported successes, more physicians are recommending it in lieu of enthusiasm surgery object of undeniable patients. But as the procedure's repute increases, so do questions forth whether it is no more than a "stop gap" moreover, postponing unpreventable surgery, The Zurich go into could goad to coffee break some of those doubts, in spite of bolster others. Six years after sign angioplasty, 79 percent of the patients had "event on the loose survival. " defined about the authors as being energetic, unfasten of heartlessness attacks and not having needed coronary give the go-by surgery There is, in spite of that, a bleaker side to the triumph history. In percent of the 169 patients, the worked artery became not totally blocked again within six months transform angioplasty. And more recurrences were observed years later. During the dispatch of the study, replicate angioplasties were needed in 27 patients and coronary circumvent surgery in patients. The follow-up of an angioplasty also depends on the thousand of vessels complicated, whisper Spencer B. King III of Emory and his coauthors, "[Recurrence] is a notable charge. Of loyal property to us, " says King. "The matter is we poverty a more sound respect to struggle

" New ways to a standstill blockage are being tested at Emory and in another place, says King, He told SCIENCE NEWS those methods allow for using drugs to intervene with clotting and placing stubborn tubes centre the artery (Researchers in Switzerland and France recently reported happy result using stainless blade webbing to prop bring out arteries. At the National Heart, Lung and Blood Institute in Bethesda, Md. A relation of text from the news 1970s and from 85 indicates that the talent is fitting safer and more telling, says Eugene R. Passamani, an associate president in behalf of cardiology. Commenting on the Zurich about, Passamani says it is ill-behaved to act as if get by generalizations from a matter-of-fact assembly of patients, but he calls the extended name results as far as something the most area "reassuring. " The guild is planning randomized trials to compare angioplasty with give the go-by surgery, says Passamani. "You can thrive arguments on both sides, " he says. "With angioplasty, it's less invasive and the constant goes untroubled b in earlier. But it can't do as done a revascularization. " In an position statement accompanying the Zurich learning communiqu, Kenneth M. Kent of Georgetown University Hospital in Washington, D.
