GLP-1 receptor agonists were associated with lower rates of death and limb complications in people with both peripheral artery disease (PAD) and type 2 diabetes, according to a new analysis.

REPAIR Study Challenges the Notion That Small Mitral Valve Area Is a Barrier to PASCAL Repair

Jul 09, 2026 by
Will Chu, CRTonline.org

Small mitral valve orifice area should not automatically rule out mitral valve transcatheter edge-to-edge repair with the PASCAL system, new findings from the REPAIR study suggest.

TUXEDO-2 Trial Shows Noninferiority of Sirolimus-Eluting Stent vs Everolimus-Eluting Stent in Diabetic Patients

Jul 01, 2026 by
Bailey G. Salimes, CRTonline.org

An ultra-thin biodegradable polymer sirolimus-eluting stent (SES) can be used as safely and effectively as a durable polymer everolimus-eluting stent (EES) in patients who have diabetes plus multivessel disease who undergo percutaneous coronary intervention (PCI), results from the TUXEDO-2 trial show.

ACC Statement Emphasizes Selective Aspirin Use, Shorter DAPT Options for ASCVD

Jul 01, 2026 by
Nathan Gray, CRTonline.org

Aspirin's long-standing role in atherosclerotic cardiovascular disease (ASCVD) is narrowing, and shorter courses of dual antiplatelet therapy (DAPT) followed by P2Y12 inhibitor monotherapy offer a bleeding-sparing option for selected patients after percutaneous coronary intervention (PCI), according to a new scientific statement from the American College of Cardiology (ACC).

Jun 29, 2026 by
Natalie Morrison, CRTonline.org

A valve syndrome framework, including both clinical presentation and objective markers, could refine surveillance and intervention strategies for patients with severe aortic stenosis (AS) who are asymptomatic, according to a new Japanese registry.

AI Model Outperforms GRACE Score in Predicting Cardiac Death 1-Year Post-PCI for AMI: Retrospective Analysis

Jun 29, 2026 by
Natalie Morrison, CRTonline.org

An interpretable machine learning (ML) model using only routine laboratory and demographic variables outperforms the GRACE score system in predicting 1-year cardiac death after percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI), a retrospective analysis shows.

Cardiology Experts Propose Updated Heart Failure Categories in New Consensus

Jun 29, 2026 by
Will Chu, CRTonline.org

Leading cardiology societies have published a second universal definition of heart failure that advocates for the condition to be classified according to its clinical course and presentation, not only by ejection fraction (EF).

U.S. National Study Shows Black Women Have Higher Rates of Early Onset Hypertension

Jun 23, 2026 by
Bailey G. Salimes, CRTonline.org

Black women are more likely to have early onset high blood pressure (BP) compared with White women, despite other demographic factors and especially when they are in disadvantaged neighborhoods, new research shows.

Withdrawing HF GDMT After Ejection Fraction Recovery Linked to Higher HF Relapse Risk in Meta-Analysis

Jun 23, 2026 by
Nathan Gray, CRTonline.org

Withdrawing guideline-directed medical therapy (GDMT) from patients whose heart failure has improved is associated with a higher risk of relapse and cardiovascular hospitalization, without significant differences in mortality, arrhythmia or ejection fraction, a new meta-analysis suggests.

Rapid Atrial Function Test Enhances CMR Risk Assessment in Patients With Myocarditis

Jun 22, 2026 by
Will Chu, CRTonline.org

Measuring atrial function quickly with cardiac magnetic resonance (CMR) offers another option to stratify risk in patients with possible myocarditis, beyond conventional imaging markers such as left ventricular ejection fraction (LVEF) and late gadolinium enhancement (LGE), according to new research published in JACC: Cardiovascular Imaging.
