Wearable Cardioverter-Defibrillator Use in Patients Perceived to Be at High Risk Early Post-Myocardial Infarction

摘要: Objectives The aim of this study was to describe usage the wearable cardioverter-defibrillator (WCD) during mandated waiting periods following myocardial infarction (MI) for patients perceived be at high risk sudden cardiac arrest (SCA). Background Current device guidelines and insurance coverage require either 40 days or 3 months before implanting a post-myocardial (MI), depending on whether not acute revascularization undertaken. Methods We assessed characteristics outcomes who had WCD prescribed in first post-MI. medical order registry searched were coded as having “recent MI with ejection fraction ≤35%” given an International Classification Diseases, Ninth Revision 410.xx diagnostic code (acute MI), then matched device-recorded data. Results Between September 2005 July 2011, 8,453 unique (age 62.7 ± 12.7 years, 73% male) criteria. A total 133 (1.6%) received 309 appropriate shocks. Of these patients, 91% resuscitated from ventricular arrhythmia. For shocked left fraction (LVEF) was ≤30% 106, 30% 35% 17, >36% 8, reported 2 patients. 38% revascularized, 84% LVEF ≤30%; 62% 77% LVEF ≤30%. median time index therapy 16 days. treated 75% treatment month, 96% within use. Shock success resulting survival nonrevascularized 95% revascularized Conclusions During 40-day 3-month post-MI, successfully SCA 1.4%, highest month may benefit individual selected early
