iRhythm says mSToPS study results published in JAMA
iRhythm Technologies announced that results of the mHealth Screening to Prevent Strokes, or mSToPS, study, which showed increased detection of asymptomatic atrial fibrillation, or AF, in high-risk individuals using Zio by iRhythm, have been published in the Journal of the American Medical Association, or JAMA. Utilizing an innovative home-based study design, electrocardiogram, or ECG, recording and analysis were carried out using the FDA-cleared Zio by iRhythm ambulatory continuous monitoring patch to evaluate detection of asymptomatic AF, also known as silent AF. At one-year, primary results showed that AF was newly diagnosed in 6.7 percent of patients who were actively monitored by the Zio service versus 2.6 percent in the observational control group receiving routine care. In addition, 4.0 percent of patients in the Zio monitored group were found to have potentially actionable arrhythmias other than AF including ventricular tachycardia, pause, AV block, and symptomatic supraventricular tachycardia.
