Further research introduced at ACC.23/WCC reinforce the scientific worth of the Zio suite of services
SAN FRANCISCO, March 06, 2023 (GLOBE NEWSWIRE) — iRhythm Applied sciences, Inc. (NASDAQ:IRTC), a number one digital well being firm targeted on creating trusted options that detect, predict, and stop illness, not too long ago introduced the outcomes of a number of new research on the American Faculty of Cardiology’s Annual Scientific Session Collectively With the World Congress of Cardiology (ACC.23/WCC).
The CAMELOT research, titled “Comparative Effectiveness Of Ambulatory Displays For Arrhythmia Prognosis: A Retrospective Evaluation Of Medicare Beneficiaries,” demonstrated that:
-
Lengthy-term steady monitoring (LTCM) with Zio XT is related to the best diagnostic yield and the quickest time to scientific prognosis in comparison with all different ambulatory cardiac screens (ACM) when taking a look at specified arrhythmias.
-
Zio XT has the bottom chance of retesting in comparison with all different ACMs.
-
Zio XT is related to the bottom acute care healthcare useful resource utilization in comparison with all different ACMs.
The CAMELOT research is the most important and most up to date real-world, comparative effectiveness evaluation1,2 of ambulatory cardiac monitoring. Utilizing a full (100%) pattern of Medicare knowledge, the research sought to judge yield of scientific prognosis, retesting charges, and well being care utilization throughout 4 classes of ambulatory cardiac monitoring: Holter, long-term steady monitoring (LTCM), cell cardiac telemetry (MCT), and ambulatory occasion monitor.
The principal discovering is that Zio XT, prescribed for as much as 14 days of monitoring, is related to the best diagnostic yield and quickest time to prognosis, lowest odds of 180-day retesting, and the bottom danger of emergency division and inpatient hospitalization in comparison with Holter, MCT, ambulatory occasion screens, and different LTCM providers.
“Ambulatory exterior ECG monitoring is being extensively utilized in scientific apply. Suppliers have decisions of varied varieties of ECG screens, in addition to alternative of a number of distributors. There has beforehand been no try to find out whether or not these decisions affect essential endpoints corresponding to diagnostic yield or want for re-testing,” stated Suneet Mittal, MD, director of electrophysiology at Valley Well being System and presenting creator of the research. “The CAMELOT research gives actual world proof that these decisions certainly influence these outcomes and should inform how suppliers make these decisions in scientific apply.”
The introduced findings demonstrated that every one different monitoring providers (together with non-Zio LTCM) had an odds of scientific arrhythmia prognosis that was 20%-50% lower than Zio XT after controlling for different variables. All different monitoring providers additionally had 1.4 to five.7 higher odds of subsequent retesting in comparison with Zio XT.
“This research is a vital milestone as a result of it takes what we already find out about our know-how, service, scientific expertise, and affected person expertise — and reveals how this interprets into superiority of Zio XT for significant scientific outcomes throughout the panorama of ambulatory monitoring,” stated Mintu Turakhia, MD, MAS, chief medical officer and chief scientific officer at iRhythm. “CAMELOT reveals how consequential selecting the best monitoring service will be, from attaining a quicker scientific prognosis resulting in diminished repeated testing all the way in which to decrease emergency and inpatient well being care utilization and decrease prices.”
Outdoors of CAMELOT, different notable research have been introduced at ACC.23/WCC. The Zio monitor post-approval prolonged put on research, titled “Preliminary Actual World And Medical Expertise Of The Subsequent Technology Ambulatory ECG Zio Monitor: Implications For Commonplace And Prolonged Put on Monitoring,” in contrast Zio XT with the subsequent technology Zio monitor. It discovered the Zio monitor demonstrated even increased compliance, increased ECG analyzable time, elevated put on time and improved sign high quality than Zio XT. Publish-clearance evaluations of this subsequent technology ECG monitor confirmed constant and even improved efficiency in comparison with Zio XT, with potential to drastically enhance monitoring and decision-making. The Zio monitor was designed with even higher affected person consolation in thoughts – consisting of a brand new wearable biosensor that’s 72% smaller and 55% lighter whereas additionally incorporating a brand new breathable adhesive. It’s at present in restricted business launch in the USA, with a full business launch deliberate for later in 2023.
The outcomes of the VT prognostic worth research, titled “Prevalence And Prognostic Worth Of Ventricular Tachycardia On Ambulatory ECG Monitoring,” discovered that non-sustained ventricular tachycardia was independently related to elevated mortality, and should act as a proxy biomarker for cardiovascular danger.

Utilizing claims knowledge from the complete Medicare fee-for-service database (inclusive of half A, half B, and half D claims), the authors carried out a retrospective evaluation of sufferers with first-time ambulatory cardiac monitoring (ACM) in 2017-2018. Inside long-term steady monitoring (LTCM), they recognized use of the Zio XT monitor from Nationwide Supplier Identifier codes. The authors evaluated 90-day diagnostic yield (arrhythmia prognosis), 180-day retest (one other ACM) and 90-day well being care utilization. The cohort included 287,789 sufferers [age 76 ±7 years, 61% female; 10% AEM, 54% Holter, 13% LTCM, 23% mobile cardiac telemetry (MCT)]. Sufferers with Zio XT had the best diagnostic yield (adjusted odds ratio versus Holter: 1.95 [1.90-2.00, p < 0.001]) and lowest retest (adjusted odds ratio versus Holter 0.74 [0.72-0.77, p < 0.001]), even when in comparison with different LTCM or MCT. Fewer sufferers with LTCM had 90-day emergency room visits (12% versus 15%-16% different ACMs, p < 0.001) and hospitalization (8% versus 13%-14% AEM or MCT, p < 0.001).

This report particulars the primary put on and scientific expertise of the Zio monitor, a smaller, lighter and extra patient-friendly subsequent technology electrocardiogram (ECG) monitor (in comparison with present Zio XT and AT screens) cleared by the FDA in Could 2021. Industrial knowledge have been analyzed from 673 screens prescribed by 75 US physicians. Moreover, 30 topics enrolled in an IRB-approved, extended-wear validation research of security and feasibility of 30-day put on. Zio screens demonstrated excessive compliance and high-quality ECG. Put on metrics and analyzable ECG have been in comparison with nationwide Zio XT prescriptions. Arrhythmia yield was 77.1% for Zio XT and 80.9% (p=0.0168) for the Zio monitor. Thirty-day scientific knowledge demonstrated excessive compliance and excessive analyzable ECG with no clinically vital pores and skin irritation. Prolonged put on monitoring yielded extra scientific findings past 14 days. Publish-clearance evaluations of this subsequent technology ECG monitor confirmed constant and even improved efficiency in comparison with Zio XT, with potential to drastically enhance monitoring and decision-making in advanced sufferers.

Authors: Krishna Pundi, MD; Jun Fan; Natasha Din, MD; Alex Sandhu, MD; Paul A. Heidenreich, MD; Mintu Turakhia, MD, MAS
The authors carried out a retrospective cohort research utilizing knowledge from the Veterans Well being Administration, together with people who obtained a Zio XT monitor between 2011 to 2020. They analyzed 134,142 sufferers. There have been 58,495 (44%) sufferers with non-sustained ventricular tachycardia (NSVT) and 443 (0.3%) sufferers with sustained VT; 2.4% of sufferers had symptom triggers with VT. There was an elevated danger of loss of life after NSVT (hazard ratio (HR) 1.25 [95% CI: 1.20-1.29], p<0.0001) and sustained VT (HR 1.39 [95% CI: 1.09-1.77], p<0.0087). Coronary heart failure, coronary artery illness, atrial fibrillation, historical past of VT/ICD, and left ventricular ejection fraction < 40% have been all independently related to an elevated danger of NSVT. The authors conclude that NSVT was extremely prevalent on long-term steady monitoring and represents a chance for refined danger stratification to establish sufferers for additional diagnostic analysis or remedy.
