KIRKLAND, Wash., Nov. 10, 2025 (GLOBE NEWSWIRE) — Kestra Medical Technologies, Ltd. (Nasdaq: KMTS), a wearable medical device and digital healthcare company, today announced primary results from the ASSURE® WCD Clinical Evaluation Post-Approval Study (ACE-PAS), presented as a late-breaking science session at the American Heart Association (AHA) Scientific Sessions 2025 in New Orleans. ACE-PAS, the largest prospective real-world study of wearable defibrillators to date, confirmed the strong safety and effectiveness of the ASSURE WCD in clinical practice. “ACE-PAS delivers robust, real-world evidence on how the ASSURE WCD performs in routine care and provides contemporary data describing the risk of life-threatening ventricular tachycardia and fibrillation in diverse populations with reduced cardiac function,” said Jeanne E. Poole, MD, Professor of Medicine at the University of Washington and Principal Investigator. “Life-threatening arrhythmias can occur early in patients with low ejection fraction who have recently experienced a myocardial infarction, undergone coronary revascularization, or have been newly diagnosed with heart failure. These patients may have significant recovery of heart function during a waiting period of one to six months, such that a permanently implanted defibrillator is not indicated. The ASSURE WCD should be considered to protect patients at elevated risk of sudden cardiac death during this vulnerable time.” The study enrolled 21,612 patients across the United States. Key findings demonstrate consistent safety, effectiveness, and compliance in real-world use: Proven effectiveness The primary effectiveness endpoint was achieved, with 100% successful conversion for ventricular tachycardia and fibrillation (VT/VF) events, surpassing the prespecified performance goal. Validated safety The study met its primary safety endpoint, with an inappropriate-shock rate of 0.0065 per patient-month, below the prespecified performance goal and confirming a strong safety profile. Minimal false alarms 94% of patients experienced no false positive shock alarms, ensuring confidence and comfort during wear. Critical protection 2.6% of patients experienced at least one life-threatening VT/VF event within only a few months, highlighting the importance of protection in this vulnerable population. Additional clinically relevant arrhythmias revealed The ASSURE system facilitated detection of high-rate atrial fibrillation in 4.2% of patients (35% previously undiagnosed) and severe bradycardia/asystole in 0.3%, enabling the potential of timely intervention. High compliance Patients wore the device for a median of more than 23 hours per day, and one-third continued use beyond 90 days—highlighting its practicality in real-world, long-term care. “These results reinforce the critical role wearable device monitoring and therapy can play in protecting patients during periods of elevated risk,” said Brian Webster, President and Chief Executive Officer of Kestra Medical Technologies. “As the largest and most contemporary study of its kind, ACE-PAS provides compelling evidence that may help inform future updates to clinical practice—particularly around how physicians identify and protect patients at early risk of sudden cardiac death. By pairing proven performance with connected, data-driven insight, Kestra is redefining what’s possible in wearable protection and advancing evidence-based innovation.” The ACE-PAS results represent a significant step forward in understanding and managing sudden cardiac arrest risk. Additional analyses from the study will be shared in forthcoming scientific forums. A recorded panel discussion featuring ACE-PAS investigators and other leading clinical experts, hosted by MedAxiom, offers further perspective on the study’s design, outcomes, and implications for patient care.
