People who survive a heart attack face the greatest risk of dying from sudden cardiac death (SCD) during the first month after leaving the hospital, according to a long-term community study by Mayo Clinic researchers of nearly 3,000 heart attack survivors. Sudden cardiac death can happen when the hearts electrical system malfunctions; if treatment — cardiopulmonary resuscitation and defibrillation — does not happen fast, a person dies. After that first month, the risk of sudden cardiac death drops significantly — but rises again if a person experiences signs of heart failure. The research results appear in the Nov. 5 edition of Journal of the American Medical Association. Veronique Roger, M.D., a Mayo Clinic cardiologist provides an overview of the study and it's findings.
