March 3, 2026: Hypertrophic Cardiomyopathy in Focus—MAPLE-HCM Trial, Myosin Inhibitors & What Improvement Really Means | JACC This Week

Author: American College of Cardiology March 3, 2026 Duration: 18:10

In this episode of JACC This Week, Dr. Carolyn Lam and Dr. Harlan Krumholz spotlight a mini-focus issue on hypertrophic cardiomyopathy (HCM), a field undergoing rapid transformation.
The discussion centers on the MAPLE-HCM trial comparing aficamten and metoprolol in symptomatic obstructive HCM, highlighting multidomain response analysis and what it means to measure meaningful improvement. Beyond gradients and biomarkers, the conversation explores a critical question: when physiologic surrogates improve, how should we interpret patient-centered outcomes?
Framed by the Editor's Page, "What Does Improvement Mean?", this episode examines the evolving role of myosin inhibitors, disease modification, and the tension between surrogate markers and real-world clinical benefit.
Additional highlights include disaggregation of Asian ethnicities in heart failure quality-of-care research and emerging evidence on AI-driven ECG models to predict incident heart failure—underscoring JACC's commitment to precision, equity, and innovation.
This issue reflects a broader shift across cardiology: transforming once-static diseases into treatable chronic conditions guided by rigorous evidence.


Every week, the editors of one of the world's leading cardiology journals sit down for a conversation that goes beyond the printed page. JACC This Week, from the American College of Cardiology, brings together Editor-in-Chief Dr. Harlan Krumholz and Senior Consulting Editor Dr. Carolyn S.P. Lam. Their discussions provide essential context for the complex research published in the Journal of the American College of Cardiology, translating high-level science into meaningful insights. You’ll hear them dissect new studies, debate emerging trends, and explore the real-world implications of the latest findings in cardiovascular medicine. This isn't just a summary of the issues; it's a dialogue about how evidence is shaping modern heart care, from prevention to advanced intervention. The podcast serves as a direct line to the experts who are curating the science that defines global standards. Each episode feels like joining an informed, behind-the-scenes editorial meeting, where the nuances of patient care and clinical practice are thoughtfully examined. For anyone invested in cardiology-whether a practicing clinician, a researcher, or a dedicated student-this regular audio companion offers clarity and a deeper understanding of the forces driving the field forward. It’s where the published data meets practical conversation, all through the accessible format of a weekly podcast.
