Cleerly ISCHEMIA vs ZEUS System
AI Verdict
Choose Cleerly ISCHEMIA if…
Choose Cleerly ISCHEMIA if you need a non-invasive, detailed assessment of coronary artery disease, particularly when evaluating the likelihood of ischemia at a vessel level. This tool is ideal for patients undergoing CCTA scans who require comprehensive plaque characterization, stenosis severity assessment, and functional insights to guide personalized treatment strategies for heart disease.
View Cleerly ISCHEMIA →Choose ZEUS System if…
Choose the ZEUS System if you require long-term, continuous cardiac monitoring to detect and characterize arrhythmias, such as Atrial Fibrillation. This system is best suited for patients experiencing intermittent symptoms or those needing extended surveillance for suspected or known rhythm disorders, providing AI-powered analysis of ECG data from wearable biosensors.

Head-to-Head
AI-generated assessment across six dimensions based on each tool's documented features and compliance posture. Grounded in public data — not a substitute for hands-on evaluation.
Usability
ZEUS SystemTool B (ZEUS System) offers a 'wear and forget' patient experience with its Zio patch, enhancing patient compliance and ease of use for long-term monitoring. Its robust HL7-based EHR integration, including specific support for Epic via Aura, streamlines clinical workflows from patient registration to report interpretation. While Tool A (Cleerly ISCHEMIA) provides interactive web-based reports and PowerScribe integration, Tool B's broader patient and system-level usability, particularly its seamless EHR integration, gives it an edge.
Clinical Value
Cleerly ISCHEMIATool A (Cleerly ISCHEMIA) provides a comprehensive, non-invasive '3-in-1 approach' to assess atherosclerosis, stenosis, and ischemia from a single CCTA scan, including non-invasive FFR estimation and detailed plaque characterization. Clinical studies show it significantly reduces the need for further invasive testing and increases the use of preventive medications. While Tool B (ZEUS System) offers high diagnostic yield for arrhythmias, Cleerly ISCHEMIA's ability to provide detailed anatomical and functional insights for CAD from a single non-invasive test represents a more transformative impact on diagnostic pathways and treatment planning.
Pricing & Value
Cleerly ISCHEMIABoth tools have opaque pricing, requiring direct contact for details. However, Tool A (Cleerly ISCHEMIA) has established Category I CPTu00ae codes (75580 for FFR estimation and 75577 for plaque analysis effective 2026) for reimbursement, providing a clear pathway for providers to bill for the service. This transparency in reimbursement, even without specific pricing, offers a stronger value proposition for healthcare systems compared to Tool B (ZEUS System), which, despite being described as 'cost-effective' and having favorable cost-effectiveness study results, lacks specific billing codes in the provided information.
Enterprise Readiness
ZEUS SystemBoth tools are FDA-cleared, HIPAA compliant, and offer BAAs. Tool B (ZEUS System) explicitly highlights '450+ integrations inclusive of all major ambulatory EHR systems' and specific integration with Epic via the Aura network, simplifying implementation for large health systems. It also emphasizes a 'highly scalable' and 'highly durable, geographically distributed architecture' with 'redundant systems'. While Tool A (Cleerly ISCHEMIA) integrates with PowerScribe, Tool B's broader EHR integration capabilities and explicit scalability claims make it more ready for diverse enterprise environments.
Innovation
Cleerly ISCHEMIATool A (Cleerly ISCHEMIA) demonstrates greater innovation by non-invasively estimating fractional flow reserve (FFR) and providing detailed coronary plaque characterization (volume, type, location) directly from CCTA scans. This capability offers a 'novel care paradigm' by deriving functional insights from an anatomical scan, potentially replacing more invasive or additional stress tests. While Tool B (ZEUS System) leverages AI for long-term arrhythmia detection from wearables, the core concept of continuous ECG monitoring is more established, making Cleerly ISCHEMIA's approach a more disruptive advancement.
Support & Docs
ZEUS SystemTool B (ZEUS System) provides comprehensive support, including readily available 'Instructions for Use' documents in multiple languages and 24/7 customer support via phone. It also offers a 'Patient Support & FAQs' and a 'Clinical Resource Center' for healthcare professionals. Tool A (Cleerly ISCHEMIA) offers client support via a form for existing users, but lacks the explicit detail on 24/7 availability or the breadth of readily accessible documentation that Tool B provides.
