Out-of-Hospital Cardiac Arrest in Septuagenarians, Octogenarians, and Nonagenarians in Japan: Trends and Patterns in Outcomes | JACC Baran
Hosts Mitsuaki Sawano, MD, Shun Kohsaka, MD, and Nobuhiro Ikemura, MD, welcome Yuichi Saito, MD, of Chiba University Hospital, to discuss recent trends in out-of-hospital cardiac arrest (OHCA) among Japan’s oldest populations. Using data from the All-Japan Utstein Registry, Dr. Saito and the Japanese Circulation Society Resuscitation Science Study (JCS-ReSS) Group highlight that OHCA cases in nonagenarians are steadily increasing. Despite prehospital resuscitation efforts, outcomes—particularly neurologically favorable survival—remain poor in this age group. The study underscores the urgent need for a national conversation on resuscitation strategies in a super-aging society.

Zeroing In on Prevention: ARIC and the Future of Cardiovascular Risk | JACC Baran
Hosts Mitsuaki Sawano, MD, Shun Kohsaka, MD, Kentaro Ejiri, MD, and Satoshi Shoji, MD, welcome Dr. Kunihiro Matsushita of Johns Hopkins University to discuss findings from the ARIC study on cumulative cardiovascular risk and healthy arterial aging. Dr. Matsushita highlights that maintaining favorable levels of cholesterol, blood pressure, and avoiding smoking from mid- to late-life is strongly associated with the absence of coronary artery calcium (CAC) at older age—a marker of healthy arterial aging. The study emphasizes the long-term impact of sustained risk factor control and its implications for preventive cardiology and public health.

Epidemiology and Outcomes in HFimpEF | JACC Deep Dive
In this JACC Deep Dive, Editor-in-Chief Harlan M. Krumholz, MD, SM, discusses a large real-world study by Min et al. examining heart failure with improved ejection fraction (HFimpEF) in over 24,000 patients. The study found that while EF improvement is common (30%), true remission is rare and relapse occurs in about 25% of cases—highlighting the need for continued guideline-directed medical therapy (GDMT) even after apparent recovery. Listen to the podcast, find out what reviewers and editors liked about the paper, and get more insight into our dedicated focus issue on heart failure.

Heart Failure in Practice: Dual Therapy Insights, Digital Innovation & the Future of Risk Models | JACC This Week
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.

JACC Editor's Page: June 30, 2025 | JACC
Cardiac electrophysiology is rapidly evolving, blending procedural expertise with innovations in pharmacotherapy, device design, and lifestyle medicine. This week's Editor's Page spotlights key studies from JACC that challenge long-standing practices—from lifestyle strategies for atrial fibrillation to the role of defibrillation testing and device comparisons. We also explore disparities in cardiac arrest outcomes and complex real-world cases that push clinical boundaries. Tune in for a dynamic look at the future of arrhythmia care.
Weekly summary and focused insights of the high-impact cardiovascular research published in the JACC from Editor-in-Chief Harlan M. Krumholz, MD, SM, FACC, shaping cardiovascular care today.
