Out-of-Hospital Cardiac Arrest in Septuagenarians, Octogenarians, and Nonagenarians in Japan: Trends and Patterns in Outcomes | JACC Baran

Jul 29, 2025

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.
