Drug-Coated Stents Safe for Heart Attack Patients, Study Finds

Drug-coated stents are safe for patients with myocardial infarction and improving their chances of survival, according to medical research in the context of a reunion. The patients in whom the devices prop open their hearts arteries should be crushed for a year to prevent deadly blood clots in developing countries. While many doctors use the drug covered stents, Boston Scientific Corp., Johnson & Johnson and Medtronic Inc., and others have interfaces back for fear that some patients with myocardial infarction is not consistent medicine Anti-clot. A database of 7216 patients in Massachusetts who found that the drug was covered with appliances must review the procedure rare or die more than bare metal stents, and heart attack rates by blood clots were similar. A second study conducted by Italian researchers have found great heart complications were in half the drugs coated devices. Although neither “ bare metal stents still drug-eluting stents were originally approved and recruitment of heart attacks, it is undoubtedly the main condition, we are dealing with stents,’’said Laura Mauri, director of Harvard scientific researcher of the Institute of Clinical Research in Boston. “ I feel comfortable, considering drug-eluting stents on the basis of these results,”, patients take their medication, she said. The studies were presented today at a joint meeting of the society of the cardiovascular system and interventions angiography and the American College of Cardiology, Chicago. Coating Concern The preparation, the coating can be affixed to the equipment to the healing of the artery, which were already inflamed, and perhaps more vulnerable to blood clots, said Paul Gurbel, director of the cardiovascular, to search Sinai Hospital of Baltimore, in an interview. Yet many doctors, as they are known, in order to introduce the need for retreatment, he said. Mauri In the study, 15.5 percent of patients receiving drug-coated stent need for a repetition of the proceedings, within a period of two years for its arteries, compared to 20.8 percent of persons Oldest, Bare-Metal-peripherals. Mortality 10.4 percent in the other patients from one surface, as compared to 13.2 percent in the group of older people. The second study compared the two types of stents in 745 patients with myocardial infarction in Italy, Spain and Argentina. After eight months of 7.8 percent of patients receiving Johnson & Johnson’s Cypher died, had a heart attack or need for repeat retreatment, compared to 14.5 percent rather than a stent. The number of the late stent blockages in the two groups was similar. Patients were also Bristol-Myers Squibb Co. And Sanofi-Aventis SA Plavix for at least three months. The study was conducted by Merck & Co., a drug developed during the process of implanting stents. Sales Decline United States, sales of medicines coated stents has plunged 37 percent during the year 2007, after studying proposed unexpectedly perhaps patients in the form dangerous blood clots, block devices more ” one year after established. Further research over the last year, the drug therapy May aggressive treatment of chronic pain in the chest, as well as the devices implanted permanently, reducing their use. Two recent studies, and other results suggest that doctors perhaps gone too far in reducing the use of stents coated with drugs, “said Magnus Ohman, director of advanced coronary artery disease at Duke University Medical Center. The overall mortality rates include those blood clots, so-called late stent thrombosis, and a reduction is encouraging, he said. “ It’s provocative,’’said Ohman, who is not under consideration, in an interview. “ Maybe we exceeded.” |
