Further research offered at ACC.23/WCC reinforce the medical worth of the Zio suite of services and products
SAN FRANCISCO, March 06, 2023 (GLOBE NEWSWIRE) — iRhythm Applied sciences, Inc. (NASDAQ:IRTC), a number one digital well being firm centered on creating trusted options that detect, predict, and stop illness, lately offered 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 medical analysis in comparison with all different ambulatory cardiac displays (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 guage yield of medical analysis, 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 analysis, lowest odds of 180-day retesting, and the bottom threat of emergency division and inpatient hospitalization in comparison with Holter, MCT, ambulatory occasion displays, and different LTCM companies.
“Ambulatory exterior ECG monitoring is being broadly utilized in medical observe. Suppliers have selections of varied kinds of ECG displays, in addition to alternative of a number of distributors. There has beforehand been no try to find out whether or not these selections affect essential endpoints reminiscent of diagnostic yield or want for re-testing,” mentioned Suneet Mittal, MD, director of electrophysiology at Valley Well being System and presenting creator of the research. “The CAMELOT research offers actual world proof that these selections certainly affect these outcomes and should inform how suppliers make these selections in medical observe.”
The offered findings demonstrated that every one different monitoring companies (together with non-Zio LTCM) had an odds of medical arrhythmia analysis that was 20%-50% lower than Zio XT after controlling for different variables. All different monitoring companies additionally had 1.4 to five.7 better odds of subsequent retesting in comparison with Zio XT.
“This research is a crucial milestone as a result of it takes what we already learn about our know-how, service, medical expertise, and affected person expertise — and reveals how this interprets into superiority of Zio XT for significant medical outcomes throughout the panorama of ambulatory monitoring,” mentioned Mintu Turakhia, MD, MAS, chief medical officer and chief scientific officer at iRhythm. “CAMELOT reveals how consequential choosing the proper monitoring service might be, from attaining a sooner medical analysis resulting in diminished repeated testing all the way in which to decrease emergency and inpatient well being care utilization and decrease prices.”
Exterior of CAMELOT, different notable research have been offered at ACC.23/WCC. The Zio monitor post-approval prolonged put on research, titled “Preliminary Actual World And Scientific Expertise Of The Subsequent Technology Ambulatory ECG Zio Monitor: Implications For Customary And Prolonged Put on Monitoring,” in contrast Zio XT with the subsequent era Zio monitor. It discovered the Zio monitor demonstrated even larger compliance, larger ECG analyzable time, elevated put on time and improved sign high quality than Zio XT. Publish-clearance evaluations of this subsequent era ECG monitor confirmed constant and even improved efficiency in comparison with Zio XT, with potential to enormously enhance monitoring and decision-making. The Zio monitor was designed with even better 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 presently in restricted business launch in the US, 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 threat.

Utilizing claims knowledge from the total 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 analysis), 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 medical expertise of the Zio monitor, a smaller, lighter and extra patient-friendly subsequent era electrocardiogram (ECG) monitor (in comparison with current Zio XT and AT displays) cleared by the FDA in Might 2021. Business knowledge have been analyzed from 673 displays 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 displays 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 medical knowledge demonstrated excessive compliance and excessive analyzable ECG with no clinically important pores and skin irritation. Prolonged put on monitoring yielded further medical findings past 14 days. Publish-clearance evaluations of this subsequent era ECG monitor confirmed constant and even improved efficiency in comparison with Zio XT, with potential to enormously enhance monitoring and decision-making in complicated 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 threat of dying 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 threat of NSVT. The authors conclude that NSVT was extremely prevalent on long-term steady monitoring and represents a possibility for refined threat stratification to determine sufferers for additional diagnostic analysis or remedy.
