The 2026 Second Universal Definition of Heart Failure introduces a more dynamic framework that moves beyond fixed ejection fraction thresholds to account for disease trajectory, underlying cause, and clinical context. To learn more, join Ryan Quigley as he reviews the updated approach to ejection fraction, key distinctions between improvement and recovery, and new classifications for heart failure trajectory and cause.

A post hoc analysis of a randomized phase 3b trial evaluated four-factor prothrombin complex concentrate (4F-PCC) versus plasma for urgent vitamin K antagonist (VKA) reversal in adults requiring orthopedic surgery. While both treatments demonstrated comparable hemostatic efficacy and similar safety profiles, 4F-PCC produced substantially faster INR reduction and shortened the median time to surgery by more than 13 hours compared with plasma. These findings add to the growing body of evidence supporting rapid anticoagulation reversal with 4F-PCC in time-sensitive orthopedic procedures. Tune in as Dr. Matt Birnholz reviews the study results, their clinical implications, and important limitations that should inform our interpretation.

Despite expanding treatment options, many patients with chronic spontaneous urticaria (CSU) continue to experience persistent itch and hives that can significantly affect their quality of life. Tune in to hear Ryan Quigley review pooled results from the phase 3 REMIX-1 and REMIX-2 studies, highlighting how remibrutinib delivered rapid symptom relief, sustained disease control through one year, and a favorable long-term safety profile for adults with CSU.

New real-world data are reshaping the conversation around transthyretin suppression in transthyretin amyloidosis. In this AudioAbstract, Ryan Quigley explains how a crossover analysis revealed substantially deeper serum transthyretin suppression with vutrisiran than patisiran, raising important questions about whether more complete silencing could influence long-term outcomes.

New findings from a post hoc analysis of the Burden of Disease survey highlight how symptom severity and loss of independence in patients with transthyretin amyloid cardiomyopathy (ATTR-CM) contribute to increased caregiver burden, fatigue, anxiety, and depression. In this AudioAbstract, Ryan Quigley discusses which patient-reported symptoms and limitations were most strongly associated with distress and explains why preserving mobility and functional independence may be critical to improving outcomes for both patients and caregivers.

While transthyretin amyloid cardiomyopathy (ATTR-CM) is often viewed solely as a disorder of protein misfolding, a new review published in the European Heart Journal presents it as a dynamic imbalance between amyloid production and clearance. Hear from Dr. Hallie Blevins as she reviews pivotal data on ATTR-CM's expanding therapeutic landscape.

An April 2025 Current Cardiology Reports article provides new insights into the role of cardiac magnetic resonance (CMR) and genetic data in diagnosing hereditary transthyretin amyloid cardiomyopathy (ATTR-CM). Learn more about this potential approach with Ryan Quigley in this AudioAbstract.

Can real-time transepidermal water loss (TEWL) monitoring reduce the risk of anaphylaxis during oral food challenges in young children with peanut allergy? A pilot trial suggests it may. TEWL-guided stopping significantly lowered anaphylaxis rates and reaction severity without delaying treatment. This benefit was linked to earlier discontinuation of allergen exposure based on physiologic changes, rather than faster intervention. While larger studies are needed, these findings support TEWL monitoring as a promising tool to enhance safety and decision-making during food challenges.

Distinct immune pathways in T2high and T2low asthma are shaping more precise therapies. To learn more, tune in as Ryan Quigley explores how endotype insights are guiding current and emerging immunotherapy strategies.

For patients with multiple sclerosis (MS), cognitive impairment can quietly erode independence and quality of life. In this AudioAbstract, Dr. Hallie Blevins discusses a head-to-head comparison of cognitive training, aerobic exercise, and a combined approach and explores how we can better support cognition in these patients.
