Zio® by iRhythm Shown to Prevent Hospital Admissions, Aid in Early Detection of AF
- New clinical research presented at ACC.22 shows that the Zio service is a viable solution for the early detection of silent atrial fibrillation
- Additional data shows that Zio AT can positively impact hospital resources – saving one healthcare system 136 inpatient hospitalization days
- Further validates the Zio service as a viable solution for the early detection of atrial fibrillation (AF),1 helping undiagnosed populations effectively seek treatment before more serious problems can occur.
- Shows that the Zio service can positively impact hospital resources2 – a crucial benefit during the continued COVID-19 pandemic.
- Supports the need for monitoring post-TAVR discharge in high-risk patient populations.3
“As the healthcare system continues to progress towards value-based medicine, we recognize that providers are increasingly challenged to improve clinical outcomes for patients while controlling costs,” said
The Syncope study, titled “Syncope Pathway Using Live Ambulatory Monitoring Streamlines ER Patient Disposition,” found that Zio AT was able to monitor and aid in diagnosis of qualified syncope patient candidates in an outpatient setting. Implementation of Zio AT allowed health systems to safely monitor patients upon discharge, avoiding a potential 24-48 hour hospital stay. Additionally, 8.2% of patients had an arrhythmia event triggering an MD notification. Nearly half (46%) of these occurred after 48 hours (longer than atypical inpatient stay) – demonstrating the importance of 14-day monitoring with Zio AT. Finally, it was concluded that use of Zio AT saved the healthcare system an estimated 136 inpatient hospitalization days.

Lastly, research highlighted in the Rutgers-TAVR study, titled “Ambulatory Electrocardiographic Monitoring Following Transcatheter Aortic Valve Replacement (TAVR) In Different Age Groups,” demonstrates that monitoring with Zio AT post-TAVR discharge can identify AF, high degree atrioventricular block (HAVB), and supraventricular tachycardia (SVT) in patients who are at risk for arrhythmic disorders. During monitoring, in which patients wore the device for up to 14 days, the most common arrhythmias were AF (25%) followed by HAVB (7%) and SVT > 30 secs (6%). The results support the need for monitoring post-TAVR discharge in high-risk patient populations.

About the Syncope Study
Implementation of an evidence-based syncope pathway (SP) using remote near real-time telemetry monitoring allows health systems to safely monitor appropriate patients upon discharge, avoiding a potential 24-48 hour hospital stay. A SP was developed in which patients were stratified into low, medium, and high-risk groups based on medical history and Canadian Syncope Risk Score. The SP identified appropriate patients for monitoring via Zio AT. 183 patients were discharged with a Zio AT device from the emergency department. 8.2% (15/183) of patients had an arrhythmia event triggering an MD notification (MDN). Average time from Zio AT application to MDN was 89 hours. 62% of the MDNs occurred after the 24-hour period and 46% of MDNs occurred after the 48 hours. The SP using Zio AT was advantageous to hospital workflow, improving hospital capacity by decreasing syncope inpatient hospitalization rates and saving the healthcare system 136 inpatient hospitalization days. Additionally, average time to MDN notification period was well outside the typical window of a hospital stay for syncope.
About the GUARD-
A randomized trial of screening for AF in individuals ≥ 70 years old without AF was done using a Zio XT monitor and compared, 1:1, to usual care. 5,720 participants returned Zio XT monitors (13.9 days median wear time) with analyzable data (98.4% median analyzable time). 255 (4.5%) participants had AF, including 30 (0.5%) with 100% AF. AF was more common in those ages ≥ 80 (1.0%) than among younger participants (0.40%), p < .01. In the 225 participants with paroxysmal AF (PAF), median AF “burden” was 0.48% (0.016-2.5) of time monitoring [78 (3.2, 454) minutes]. In GUARD-AF’s older primary care population, 0.5% of screened participants had persistent AF and 4% had PAF detected within two weeks of monitoring. In those with PAF, average AF burden was low but >25% had an episode of ≥4.6 hours of continuous AF, suggesting increased stroke risk. The need for stroke-preventive interventions (e.g., anticoagulants) for screen-detected PAF remains a critically important research question.
About the Rutgers-TAVR Study
Consecutive patients who underwent TAVR at a single center and discharged home with continuous AECG for 14 days using Zio AT were enrolled into a prospectively maintained database between
iRhythm is a leading digital healthcare company redefining the way cardiac arrhythmias are clinically diagnosed. The company combines wearable biosensor devices worn for up to 14 days and cloud-based data analytics with powerful proprietary algorithms that distill data from millions of heartbeats into clinically actionable information. The company believes improvements in arrhythmia detection and characterization have the potential to change the clinical management of patients.
