Results of Four Studies Demonstrating Clinical, Economic Value of iRhythm’s Product Portfolio Presented at American Heart Association ’22
iRhythm Technologies (NASDAQ: IRTC) presented four clinical studies at the American Heart Association 2022 Scientific Sessions showing significant value in their Zio® product lines for diagnosing cardiovascular issues. The studies highlighted the cost-effectiveness of atrial fibrillation (AF) screening using the Zio XT, reporting an incremental cost-effectiveness ratio of $17,000 per quality-adjusted life year. Additionally, data indicated that extended ECG monitoring improved accuracy in assessing premature ventricular contractions (PVC) and unveiled unexpected rates of AF in patients experiencing syncope.
- Demonstrated high value and cost-effectiveness of Zio XT for AF screening, with an ICER of $17,000/QALY.
- Extended ECG monitoring improves accuracy in estimating PVC burden significantly, achieving >95% accuracy.
- High diagnostic yield (79%) and unexpected AF burden (9.5%) found in syncope patients using Zio AT.
- None.
Clinical studies presented at the American Heart Association 2022 Scientific Sessions event demonstrate compelling diagnostic and health economic value of the Zio® suite of products across a range of clinical applications
SAN FRANCISCO, Nov. 07, 2022 (GLOBE NEWSWIRE) -- iRhythm Technologies, Inc. (NASDAQ:IRTC), a leading cardiovascular diagnostics and digital healthcare solutions company focused on creating trusted solutions that detect, predict, and prevent disease, today announced the results of four clinical studies presented at the American Heart Association’s (AHA) 2022 Scientific Sessions in Chicago, IL. The studies demonstrate health economic and clinical value of the Zio® AT and XT product lines across a range of diseases and clinical settings.
“The presented studies have important clinical implications,” said Dr. Mintu Turakhia, iRhythm’s chief medical officer and chief scientific officer. “First, screening for atrial fibrillation, based on the mSToPS trial, is cost-effective and can provide high value. Next, extended ambulatory ECG monitoring from our products, compared to shorter monitoring, more accurately estimates the burden of a common type of ventricular arrhythmia, which is clinically consequential to patients and important to get right. We also found that atrial fibrillation was an unexpected and important finding in patients who receive monitoring for loss of consciousness, which we already know benefits from Zio’s 14-days of ambulatory ECG monitoring compared to other diagnostics. Finally, we showed the potential for partnered healthcare system research with EHR integration, in this case for tailored care pathways for diverse populations.”
The mSToPS health economic study, titled “Cost-Effectiveness of AF Screening with Two-Week Patch Monitors: The mHealth Screening to Prevent Strokes Study,” evaluated the cost-effectiveness of screening for atrial fibrillation (AFib) with Zio XT. The analysis found that systematic screening for AFib in an at-risk population with the iRhythm Zio XT patch provided high value from a health economic perspective. Over three years, individuals prescribed Zio XT were more likely than unmonitored individuals to have outpatient visits — including to cardiologists — but less likely to require emergency department visits or hospitalization. The study demonstrated an incremental cost-effectiveness ratio (ICER) of
The ventricular arrhythmia study, titled “Assessing the Optimal Duration of ECG Monitoring Required to Accurately Establish Premature Ventricular Contraction (PVC) Burden in a Large National Database,” was a >10-year study between 2011 and 2022 that analyzed PVC burden in 25,793 patients. The study sought to determine if extended ambulatory ECG monitoring increased accuracy for estimating burden of PVCs, which require accurate assessments for actionability. The data showed that a 48-hour estimation of PVCs misclassified PVC burden compared to 14-days of ambulatory ECG monitoring. At least seven days of continuous ambulatory ECG monitoring, which is performed by the Zio AT and XT product lines, was necessary to achieve >
The study titled “Near-Real Time Extended Ambulatory ECG Monitoring in Patients With Syncope Unveils a Spectrum of Arrhythmias and High Incidence of Atrial Fibrillation” utilized iRhythm’s proprietary database containing arrhythmia findings of patients prescribed Zio AT mobile cardiac telemetry for the diagnosis of syncope, or loss of consciousness possibly from heart rhythm disorders. The study of over ten thousand patients found not only a high diagnostic yield (
The electronic health record (EHR) integration study, titled “Ascension Health System Experience with Extended Ambulatory Electrocardiographic Monitoring: Implementation of a Novel Integrated Approach to Better Characterize Disparities in Healthcare,” sought to determine the relationship of age, gender, and race for AFib detection in one of the largest private healthcare systems in the U.S. In 6,293 Ascension patients linked to Zio XT data, the study found risk of detected AFib was highest in older, white, and male patients; female, diverse patients below age ≤ 65 had the lower risk of detected AFib. The study demonstrated that EHR-linkage is not only feasible but an important step to generate tailored care pathways within a healthcare system.

Authors: Bobbi Lynn Hoppe, MD; Matthew R. Reynolds, MD; Mike Hsu, PhD; Alan Wilk, BS; Lori Crosson, PhD; Marie-Noelle Langan, MD
Data were retrospectively analyzed from 10,643 patients from U.S. institutions with a syncope indication for monitoring. Patients with recordings between July 2017 to December 2021 were analyzed. Arrhythmias were defined as: AFib, ≥30 seconds at any heart rate; SVT, ≥90 bpm for ≥4 S beats; Pause, ≥3 second; AV Block, any third or second degree AV Block (Mobitz I or II); VT, ≥100 bpm for ≥4 V beats or PVT, TdP, VF. Detected arrhythmias were characterized by duration, episode counts, rates, and/or burden (where applicable). Of the 10,643 patients studied (
