ZOLL LifeVest Wearable Defibrillator Reduces Total Mortality after Cardiac Revascularization

ZOLL Medical Corporation, a manufacturer of medical devices and related software solutions, announced that a study demonstrating a reduction in total mortality after cardiac revascularization in patients prescribed a LifeVest® Wearable Defibrillator was presented at the American Heart Association’s Scientific Sessions 2011 in Orlando. Edwin Zishiri, M.D., Cleveland Clinic, presented an abstract entitled “Use of the Wearable Cardioverter Defibrillator and Survival after Coronary Artery Revascularization in Patients with Left Ventricular Dysfunction.” The analysis sought to determine if there is a difference in survival of patients with a left ventricular ejection fraction less than or equal to 35 percent (LVEF≤35%) using the LifeVest following surgical or percutaneous revascularization (CABG or PCI, respectively) compared to patients discharged without the LifeVest. Kaplan-Meier survival, Cox proportional hazards and propensity score matched analyses were performed to determine if survival differed in patients discharged after CABG or PCI revascularization with LVEF≤35% from a national database of LifeVest patients (N=809) compared to non LifeVest patients from registries at the Cleveland Clinic (N=4,149). Survival curves showed an 80% reduction in total mortality at 90 days for LifeVest patients as compared to non LifeVest patients post PCI, with 90-day mortality of 2% for LifeVest patients versus 10% for non-LifeVest patients. In addition, LifeVest use was associated with an adjusted 57% lower risk of death in post PCI patients (pAbout ZOLL Medical Corporation ZOLL Medical Corporation develops and markets medical devices and software solutions that help advance emergency care and save lives, while increasing clinical and operational efficiencies.
