JACC This Week

In this episode of JACC This Week, Editor-in-Chief Dr. Harlan Krumholz summarizes key studies from the July 15 issue, focused on cardiovascular interventions. Topics include new insights on plaque vulnerability in acute coronary syndromes, virtual flow reserve after PCI, long-term data on FFR-guided revascularization, and stent thrombosis risk. This issue delivers high-impact, practice-relevant research for interventionalists, imaging specialists, and general cardiologists alike.

In this episode of JACC This Week, Editor-in-Chief Harlan M. Krumholz, MD, SM, FACC spotlights major electrophysiology research and clinical insights from the July 8 issue of JACC. This week's issue features new findings on left atrial appendage occlusion techniques, comparisons of atrial fibrillation stroke prevention guidelines across regions, and device-related complications such as pacemaker lead perforation and device embolization. You'll also hear highlights from JACC: Clinical Electrophysiology, including striking Amara Yad anatomical visuals and real-world clinical scenarios.

As the podcast series created by Editor Emeritus Valentin Fuster, MD, PhD, MACC, comes to an end and the new series from current Editor-in-Chief Harlan M. Krumholz, MD, SM, FACC is launched, JACC is pleased to feature an interview between the two legendary thought leaders, discussing the past and future of the journal's podcasts. The interview honors Dr. Fuster for his enduring contributions to the JACC podcast, highlighting his dedication, consistency, and global impact even after stepping down as Editor-in-Chief. This frank and heartfelt conversation serves as the bridge for JACC podcasts, as Dr. Fuster expresses confidence in the future of JACC under Dr. Krumholz's leadership.

In this heartfelt reflection on their first year as editor of JACC, Harlan Krumholz shares how listening—to authors, reviewers, readers, and the broader medical community—has revealed a deep yearning for connection, trust, and purpose in cardiovascular science. It's a call to action: to shape the future of medicine with integrity, inclusivity, and hope, and to lead not just with data, but with values that inspire and unite.

In this debut episode of JACC This Week with Editor-in-Chief Dr. Harlan Krumholz, we explore groundbreaking studies and timely insights from the July 1st issue. Highlights include the impact of wildfire smoke on heart failure risk, new hemodynamic data on mechanical circulatory support in cardiogenic shock, and sobering cardiovascular mortality trends over the past 25 years. Plus, updates on aspirin use, cognitive impairment in CVD, ACC/AHA performance measures, and a leadership reflection from ACC President Dr. Christopher Kramer.

In this issue of JACC, we explore the evolving landscape of cardiovascular care, where one-size-fits-all approaches are giving way to precision strategies rooted in individual variation. From redefining diagnostic thresholds to tailoring surveillance based on genetics and patient context, these studies illuminate a future where nuance, not averages, drives better outcomes. Join us as we unpack the science behind a more personalized, data-informed vision of heart health.

In this JACC podcast, Dr. Valentin Fuster presents five key studies, including new insights into arterial aneurysms in genetic aortopathies like Loeys-Dietz, Ehlers-Danlos, and Marfan syndromes, the implications of post-exercise troponin elevations in athletes, and 35-year outcomes of staged surgery for hypoplastic left heart syndrome. The episode also features a state-of-the-art review on heart failure with improved ejection fraction, highlighting emerging challenges and clinical strategies in this evolving phenotype.

In this episode, Dr. Valentin Fuster presents new research revealing that fewer than one-third of patients with hypoplastic left heart syndrome survive 35 years without a transplant, though many adults report good to excellent quality of life after stage reconstructive surgery. Highlighting expert insights, he underscores the urgent need for innovative treatments and dedicated care teams to improve long-term outcomes in this high-risk congenital heart disease.

Dr. Valentin Fuster dives into a fascinating study about cardiac troponin levels in middle-aged recreational athletes. Elevated troponin after intense exercise is common, but surprisingly, it doesn't indicate hidden coronary artery disease. This revelation challenges previous beliefs about athletes' heart health and opens up questions about the origins and implications of these elevations. Long-term follow-ups are crucial to fully understand what these findings mean for athletes and their cardiac health.

In this episode, Dr. Valentin Fuster discusses a landmark study from the Montalcino Aortic Consortium revealing how genetic differences in Marfan syndrome, Loeys-Dietz syndrome, and vascular Ehlers-Danlos syndrome distinctly influence the risk and location of arterial events. The findings highlight gene-specific patterns—thoracic aortic complications in Marfan and Loeys-Dietz, and peripheral arterial issues in Loeys-Dietz and Ehlers-Danlos—paving the way for personalized surveillance and management strategies.
