Heart failure is estimated to afflict approximately 5 million Americans and this number is expected to double in the next five years. Nearly 550,000 new cases of heart failure are diagnosed every year in the United States. The risk of sudden cardiac death following a myocardial infarction is the highest in the first 30 days, and patients with heart failure following myocardial infarction are at 4-6 times greater risk. The LifeVest Wearable Defibrillator is worn by patients at risk for sudden cardiac arrest (SCA), providing protection during their changing medical condition, and until their permanent risk of SCA is established. The LifeVest protects these patients during this time of highest risk while they are being optimized on medical therapy. A patient’s condition can improve from the benefits of medical therapy, including meaningful improvement to the amount of ejection fraction. However, medical therapy and stabilization can take up to three months or more, which is why wearing a LifeVest is so important. “In people diagnosed with heart failure, sudden cardiac arrest occurs at six to nine times the rate of the general population,” said Richard A. Packer, Chairman and Chief Executive Officer of ZOLL. “The LifeVest is an important therapy in the continuum of care for patients with heart failure, allowing a physician to manage a patient’s changing condition while protecting him or her from sudden cardiac arrest.” 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 continuously monitors the patient’s heart and, if a life-threatening heart rhythm is detected, the device delivers a treatment shock to restore normal heart rhythm. 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 places patients at particular risk. To date, the LifeVest has been prescribed to over 25,000 patients.
