In this focus issue on Heart Failure in Practice, JACC Editor-in-Chief Dr. Harlan Krumholz examines how contemporary research continues to refine and at times challenge our understanding of heart failure management. This week’s episode features a first-of-its-kind trial on dual therapy with SGLT2 inhibitors and MRAs, new real-world data on heart failure with improved EF, and sobering insights into what happens when foundational therapies are withdrawn. Also explored: sex-specific risks in genetic cardiomyopathies, the limitations of standard stroke prediction tools, and the case for modernizing ICD eligibility criteria. As always, the episode concludes with a synthesized summary of key takeaways for clinicians.
