Study indicates immediate intervention may not provide any benefit compared with delayed angioplasty in patients with milder heart attacks.

Bloomberg News<http://www.bloomberg.com/apps/news?pid=newsarchive&sid=aj889eZKzEQ4> (9/2, Ostrow) reports that, according to a study published Sept. 2 in the Journal of the American Medical Association<http://jama.ama-assn.org/cgi/content/full/302/9/947?home>, "patients rushed to the hospital for treatment of a suspected heart attack may fare just as well by waiting until the next day" to undergo "artery-clearing procedures, such as angioplasty or inserting a stent."


HealthDay<http://healthday.com/Article.asp?AID=630614> (9/1, Edelson) reported that, according to the researchers, "There was no significant difference in key measures of heart damage and one-month death rates in the study of 352 people with the mild form of heart attack called non-ST elevation myocardial infarction between those who had immediate angioplasty and those who waited an average of 21 hours for the procedure." In fact, the investigators "found the incidence of deaths, second heart attacks, or need for second procedures was higher in the group that had angioplasty within 70 minutes of diagnosis (13.7 percent) than in the group of patients who waited nearly a full day (10.2 percent)."


MedPage<http://www.medpagetoday.com/Cardiology/AcuteCoronarySyndrome/15791> Today (9/1, Emery) reported that the study authors concluded that "the strategy of immediate intervention does not appear to provide any benefit or harm in comparison with an intervention postponed to the next working day; it was, however, associated with a significantly shorter hospital stay." HeartWire<http://mailview.custombriefings.com/mailview.aspx?m=2009090201acep&r=1993467-2b66&l=006-df0&t=c> (9/1, Hughes) also covered the story.
