Stents keep heart arteries open NEW YORK, Jun 29 (Reuters) -- Inserting a stent into a diseased heart artery to keep it open benefits some heart attack patients more than simply opening the artery with balloon angioplasty, report Dutch researchers in the July 1st issue of the journal Circulation. The study indicates that stenting -- the insertion of a tiny tube -- "can be applied safely and effectively" in selected heart attack patients, they write. Stenting results in "a significant reduction in recurrent (heart attack)" and in the need for further procedures to open blocked coronary arteries that lead to heart attack, the team notes. Dr. Harry Suryapranata and colleagues at Hospital De Weezenlanden in Zwolle, the Netherlands, studied 227 heart attack patients for 6 months after they underwent invasive procedures to open coronary arteries. Half of these patients underwent balloon angioplasty alone, while the other half had their arteries opened using angioplasty and also had stents inserted. The rate of recurrent heart attack in the stenting group was 1%, compared with 7% in the angioplasty group, report the researchers. Repeat revascularization procedures were needed in only 4% of patients in the stenting group, compared with 17% of those who underwent angioplasty. Cardiac event-free survival was also superior in the stenting group (95%), compared with angioplasty (80%). Because the study population was small and limited to a single center, and the patients selected were in relatively stable condition with diseased arteries considered ideal for stenting, Suryapranata and others point out that their findings are currently limited to a select patient population. To address these issues, the team are conducting further studies, which will include analysis of the cost-effectiveness of more frequent stenting. "Because this group has previously demonstrated the ability to achieve superb outcomes with... (coronary angioplasty) alone, any findings favoring a primary stent strategy by these investigators would be particularly meaningful," Dr. Gregg W. Stone of The Cardiovascular Institute in Mountain View, California, points out in a related editorial. Although the findings will need to be reproduced in a larger, multicenter population, Stone believes that "stenting holds promise to be the next major breakthrough" in the treatment of heart attack patients. He adds, "Suryapranata and colleagues deserve credit for being at the forefront of this effort." SOURCE: Circulation 1998;97:2483-2485, 2502-2505.
