In this JACC Deep Dive, Dr. Harlan Krumholz highlights a study by Ikemura et al. that used data from the ISCHEMIA trial to model how angina symptoms evolve over three years in patients with stable coronary disease treated either invasively or conservatively. The study identified six distinct symptom trajectories…
In this JACC Deep Dive, Dr. Harlan Krumholz discusses a pre-specified analysis from the SUMMIT trial, which evaluated the effects of tirzepatide in patients with heart failure with preserved ejection fraction (HFpEF) and obesity, both with and without type 2 diabetes. The study found that tirzepatide significantly…
In this Deep Dive, Editor-in-Chief Dr. Harlan Krumholz explores a pragmatic, randomized crossover trial testing whether in-home HEPA filtration can reduce blood pressure in adults living near high-traffic roadways. The findings offer early insights into how targeted environmental interventions may influence…
In this episode of JACC Deep Dive, Dr. Harlan Krumholz explores new insights from a post hoc analysis of the MASTER DAPT trial, highlighting the real-world burden of ischemic and bleeding events in high bleeding risk patients after PCI. By examining recurrent—not just first—events, the study sheds light on how…
In this episode of JACC Deep Dive, KACC Editor-in-Chief Harlan M. Krumholz, MD, SM, FACC, explores a post hoc analysis of the HELIOS-B trial, which examined whether echocardiographic parameters can track treatment response in transthyretin amyloid cardiomyopathy (ATTR-CM) patients treated with vutrisiran. The study…

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…
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…
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.
