ACCEL Lite: Featured ACCEL Interviews on Exciting CV Research

AI technology transforms routine chest computed tomography (CT) scans by precisely quantifying—rather than simply detecting—key cardiovascular imaging risk factors such as heart calcification, aorta calcification, and fat around the heart. By shifting from binary "yes or no" findings to actual measurement, clinicians can more accurately identify high‑risk patients and intervene earlier to help prevent heart attacks and strokes. Patients with these imaging risk factors who were already using preventive therapies like statins and aspirin showed lower cardiovascular risk, suggesting the need for larger longitudinal studies to clarify how quantified imaging markers interact with these medications over time. In this interview, Deepak L. Bhatt MD, FACC and Tzung-Dau Wang, MD, PhD discuss "AI-Enabled Nationwide Opportunistic Screening of Non-Contrast Chest CT for Death and CV Outcomes".

Ascending aortopathy (AA) is typically asymptomatic and often diagnosed incidentally, with surgical aortic replacement recommended once aneurysmal thresholds are reached. Emerging evidence suggests that indexing aortic size to patient height may more accurately identify individuals who could benefit from earlier intervention. For AA patients who do not currently meet guideline-based criteria for surgery, the aim is to assess how height-indexed aortic measurements influence longer‑term clinical outcomes in this population. In this interview, Glenn A. Hirsch MD, MHS, FACC and Milind Y. Desai, MD, MBA, FACC discuss "Should There Be a Reappraisal of Surgical Threshold in Patients with Ascending Aortic Dilation?".

Multimodality imaging plays a pivotal role in evaluating inflammatory cardiomyopathy, particularly when cardiac sarcoidosis (CS) is suspected. Symptoms of CS include unexplained high-grade AV block, ventricular arrhythmias, reduced left ventricular function, or regional wall thinning without coronary disease. The best evaluation combines cardiac magnetic resonance imaging (MRI) for structural and scar assessment with fluorodeoxyglucose (FDG)-positron emission tomography (PET) for detecting active inflammation and extracardiac involvement.

he PANTHER study indicates that clopidogrel provides superior protection against major cardiovascular events compared to aspirin in patients with coronary artery disease, without increasing bleeding risk. This supports its use in individuals at higher risk of gastrointestinal complications, reinforcing current clinical preferences. Overall, these results could inform long-term treatment strategies and improve outcomes for millions of patients worldwide. In this interview, Alison L.
