Chicago: Treating stable heart patients with a handful of pills works just as well as propping open blocked heart arteries with a stent, U.S. researchers said on Monday, adding to evidence that less-invasive, less-costly drug treatment works as well as implanting a medical device in such patients.Stents, made by companies such as Boston Scientific Corp, Abbott Laboratories and Medtronic Inc, are still the preferred treatment for opening up blocked heart arteries in patients rushed to the hospital with an acute heart attack.But several studies have shown the heart devices are no better than drugs in patients with stable heart disease, in which heart arteries have narrowed and may be causing chest pain.The latest analysis by Dr. Kathleen Stergiopoulous and Dr. David Brown of Stony Brook University Medical Center in New York, published in the Archives of Internal Medicine, attempts to knock down lingering arguments that earlier results were based on outdated technology.Older analyses had included data from trials comparing drug treatments with balloon angioplasty, in which a balloon-tipped catheter is inserted and the balloon is inflated to open the narrowed passage.For the latest so-called meta-analysis, the team pooled data only from newer studies that compared drug treatments with stents - a wire-mesh tube used to prop open the artery and prevent it from reclosing."The question was is there any benefit to stenting the blockages in these patients as an initial therapy procedure over treating them with optimal medical therapy and referring them to get a stent if necessary," Brown said in a telephone interview.The analysis included results on more than 7,200 patients enrolled in eight studies between 1997 and 2005 comparing stents with medical therapy in stable heart patients with narrowed sections in their heart arteries."The result showed quite clearly there was no benefit of stenting as far as reducing death, heart attack, repeat procedures and even reducing symptomatic angina (chest pain)," Brown said.
