Altshock-2 Through a Regional Lens: IABP in HF-CS | JACC Baran
Hosts Mitsuaki Sawano, MD, and co-host Satoshi Shoji, MD, welcome regional associate editor Kentaro Ejiri, MD, for his debut appearance on the JACC: Baran Journal Club. Dr. Ejiri presents insights on the Altshock-2 trial, a pivotal randomized controlled trial evaluating early intra-aortic balloon pump (IABP) support in heart failure-related cardiogenic shock (HF-CS). The discussion covers the trial’s clinical relevance, key challenges, and the implications of its findings within the Japanese healthcare context. The episode also delves into evolving definitions of cardiogenic shock, trial methodology, and the potential for Altshock-2 to inform more individualized treatment approaches in Japan.

Disentangling the Impact of Adiposity From Insulin Resistance in HFpEF | JACC Deep Dive
In a Deep Dive in our May 13 issue, Editor-in-Chief Harlan Krumholz, MD, SM, FACC, discusses a study led by Barry Borlaug that investigates whether excess weight or metabolic dysfunction has a greater impact on heart failure with preserved ejection fraction (HFpEF). The findings showed that obesity—more than insulin resistance—was strongly associated with worse hemodynamic and functional outcomes. Reviewers praised the study's nuanced approach and use of invasive measures, while editorialists emphasized the ongoing importance of addressing both adiposity and metabolic health in HFpEF management.

Revisiting the SUMMIT Trial | JACC Deep Dive
This JACC Deep Dive in our May 13 issue highlights new findings from the SUMMIT CKD study, showing that terzepatide improves symptoms, function, and weight in patients with HFpEF and obesity—regardless of kidney function. The analysis also underscores the importance of using both creatinine and cystatin C to better assess kidney health. Reviewers praised the study’s methodological rigor and dual focus, while noting the need for larger, long-term trials to confirm renal outcomes.
Each week, Valentin Fuster, MD, PhD, MACC, records free podcasts highlighting journal findings. To keep clinicians updated on the most important science emerging in clinical and translational cardiology, Dr. Fuster provides an overview of the weekly edition from the Journal of the American College of Cardiology (JACC), as well as a short summary of each manuscript. Encompassing JACC and nine cardiovascular specialty journals, the JACC family of journals rank among the top cardiovascular peer-reviewed journals in the world for scientific impact.
