ZOLL LifeVest Prescribed by Physicians at All U.S. News and World Report “Honor Roll” Hospitals and All 50 “Best Cardiology and Heart Surgery” Hospitals

ZOLL Medical Corporation, a manufacturer of medical devices and related software solutions, announced that physicians at all of the 17 “Honor Roll” hospitals and all of the 50 “Best Cardiology and Heart Surgery” hospitals designated by U.S. News and World Report for 2011-2012 have prescribed the ZOLL LifeVest® Wearable Defibrillator for patients. The LifeVest is worn by patients at risk for sudden cardiac arrest (SCA), providing protection during their changing condition and while permanent SCA risk has not been established. The LifeVest allows a patient’s physician time to assess their long-term arrhythmic risk and make appropriate plans. The LifeVest is lightweight and easy to wear, allowing patients to return to their activities of daily living, while having the peace of mind that they are protected from SCA. The LifeVest does not require bystander intervention and has a 98 percent first treatment shock success rate for resuscitating patients with SCA. “For the fourth year in a row, physicians at all of the ‘Honor Roll’ and ‘Best Cardiology and Heart Surgery’ hospitals have prescribed the LifeVest to protect their patients from sudden cardiac death,” said Richard A. Packer, Chief Executive Officer of ZOLL. “The fact that physicians at all of these premier institutions prescribe the LifeVest is a testament to the important role this treatment option plays in the standard of care for patients at risk of SCA.” The LifeVest is used for a wide range of patient conditions, including following a heart attack, before or after bypass surgery or stent placement, as well as cardiomyopathy or congestive heart failure, that place patients at particular risk. To date, the LifeVest has been prescribed to more than 45,000 patients. U.S. News and World Report’s “Best Hospitals” is an annual ranking of the country’s elite medical centers that assesses how well a hospital handles complex and demanding situations. From among the 4,825 hospitals considered for the report, only 140 were ranked in one or more of the 16 specialties, and from those, only 17 qualified for the “Honor Roll” designation by earning high scores in at least six specialties. U.S. News and World Report also named the 50 “Best Cardiology and Heart Surgery” hospitals for 2011-2012 based on rankings within the specific category.
