In this episode of JACC This Week, Dr. Harlan M. Krumholz and Dr. Carolyn S.P. Lam discuss a dedicated issue of JACC focused on cardiac amyloidosis—one of the fastest-evolving areas in cardiovascular medicine. They explore new evidence highlighting significant delays in diagnosing ATTR cardiomyopathy, the early divergence of mortality benefit with timely treatment, and why time to diagnosis is no longer a neutral factor. The conversation also examines secondary analyses from major clinical trials, practical guidance for amyloidosis evaluation and management, and Dr. Krumholz's Editor's Page on "computable diagnosis" as a moral imperative. This episode places emerging science in clinical context, emphasizing urgency, equity, and how clinicians should be thinking differently about diagnosis, staging, and access to therapy in amyloid heart disease.
