Hosts Mitsuaki Sawano, MD, co-host Nobuhiro Ikemura, MD, welcome Kentaro Kamiya, PhD, from Kitasato University, to discuss the ACTIVE-ADHF trial, a landmark multicenter RCT on early cardiac rehabilitation in acute decompensated heart failure. The study found that initiating exercise-based rehab during hospitalization significantly improved physical function, quality of life, and activity levels at...

Join JACC Editor in Chief Harlan Krumholz, MD, SM, as he speaks about this ACC.25 presentation published in JACC. This fascinating study by Rohan Khera et al independently analyzed patient-level data from the SURMOUNT trials of tirzepatide for obesity. The study revealed striking individual variability in weight loss and metabolic response, even to a highly effective therapy—an insight powerfully...

This special lipid-themed issue of JACC emphasizes the importance of innovative research in lipid disorders to reduce cardiovascular risk, highlighting studies that extend our understanding of lipid biology and evaluate new treatments. Key reviews and original investigations explore novel lipid-modifying therapies, such as RNA interference and antibody therapies, demonstrating their potential in m...

In this special issue of the JACC, Dr. Valentin Fuster explores the latest findings in lipid research, covering groundbreaking therapies aimed at tackling cardiovascular risks tied to lipid disorders. Key highlights include innovative approaches to lowering triglyceride-rich lipoproteins using angiopoietin-like protein 3 inhibitors and other novel treatments, with promising data on reducing cardio...

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 tria...

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 f...

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....

In this podcast, Dr. Valentin Fuster dives into the crucial review of anthracycline-induced cardiotoxicity in adult cancer patients, exploring the molecular mechanisms, treatment regimens, and long-term cardiovascular risks associated with this widely used chemotherapy. The podcast highlights the importance of early detection, collaborative care between oncologists and cardiologists, and the devel...

In this podcast, Dr. Valentin Fuster discusses a study published in the JACC examining the impact of obesity, insulin resistance, and diabetes on patients with heart failure and preserved ejection fraction. The findings suggest that while obesity is closely linked to heart abnormalities, insulin resistance and diabetes have a less direct impact, urging further research into cardiometabolic therapi...

In this podcast, Dr. Valentin Fuster explores a study on the effects of SGLT2 inhibitors, like empagliflozin, on erythropoiesis and iron mobilization in heart failure patients. The research reveals how these drugs activate key metabolic pathways, potentially enhancing iron utilization and improving clinical outcomes, with significant implications for treatment in heart failure and chronic kidney d...

In this podcast, Dr. Valentin Fuster reviews findings from the SUMMIT trial, which examined how tirzepatide impacts patients with obesity-related heart failure with preserved ejection fraction (HFpEF) and chronic kidney disease (CKD). The study revealed that while tirzepatide improved cardiovascular outcomes and slightly boosted kidney function, the benefits in CKD patients may stem from mechanism...

In this episode, Dr. Valentin Fuster, provides a concise summary of the May 13, 2025 issue. He discusses four original studies on key cardiovascular topics, including the impact of chronic kidney disease and obesity on heart failure, the role of dobutamine stress echocardiography in predicting PCI outcomes, the effects of empagliflozin on erythropoiesis in heart failure, and the influence of adipo...

In this podcast, Dr. Valentin Fuster discusses a groundbreaking study from the Orbiter 2 trial, which explores how dobutamine stress echocardiography (DSE) can predict the efficacy of percutaneous coronary intervention (PCI) in relieving angina in patients with stable coronary artery disease. The study reveals that the degree of ischemia, as measured by DSE, is strongly correlated with improvement...

In a time of rising global tensions, JACC reaffirms its commitment to science as a unifying, borderless force—advocating for truth, equity, and collaboration to improve health worldwide. By fostering inclusive research, promoting open dialogue, and resisting politicization, JACC aims to build a global medical community working together to overcome disease and conflict.

Hosts Mitsuaki Sawano, MD, co-host Shun Kohsaka, MD, and Nobuhiro Ikemura, MD, welcome Tomohiko Taniguchi, MD, from Kobe City Medical Center General Hospital, to discuss findings from the CURRENT AS Registry-2 on low-gradient severe aortic stenosis (AS). Based on data from over 3,300 patients across 21 Japanese centers, the study categorized AS into four hemodynamic subtypes, revealing that low-gr...

In this JACC Deep Dive episode, Dr. Harlan Krumholz reviews the ADVANTAGE-AF trial, which evaluated pulse field ablation (PFA) as a treatment for persistent atrial fibrillation. The study demonstrated that PFA is a safe and effective approach, with strong symptomatic outcomes and a low complication rate, though questions remain about long-term durability and the need for more rigorous follow-up. P...

In this JACC Deep Dive episode, Editor-in-Chief Dr. Harlan Krumholz discusses a major study on sudden cardiac arrest in young competitive athletes, highlighting survival rates, causes, and racial disparities. The study shows that survival improves dramatically with immediate AED use and has increased over time, emphasizing the need for widespread emergency preparedness and health equity efforts.....
