Randomized controlled trial of 2,600 patients to study the impact of WCD use on SCD in hemodialysis patients. Read more at clinicaltrials.gov.
International randomized trial of 2,300 post-MI patients to assess the 90-day SCD benefit of WCD use, conducted by University of California, San Francisco. Read more at clinicaltrials.gov.
Heart Failure Optimization (HF Opt)
International trial to document the improvement in ejection fraction (EF) during six months of optimizing medical therapy after a recent MI or new heart failure diagnosis with EF less than 35%. Read more at clinicaltrials.gov.
Completed Clinical Trials
The following abstracts describe the results of the multi-center clinical trial which led to FDA approval of the LifeVest.
The clinical trials, which spanned three years and 17 hospitals throughout the US and Europe, included 289 patients who wore the wearable defibrillator for a collective 873 months.
During the study, the LifeVest saved six lives. The most common adverse effect reported was a temporary skin rash, and incidents of false shocks were low(<2.3% per patient-month). The results confirmed that the LifeVest is a safe and effective alternative to emergency medical services (EMS).
