The performance of estimated glomerular filtration rate (eGFR) among patients with heart failure (HF) may be worse than in the general population due to a higher prevalence of confounding factors affecting creatinine and cystatin C. Studies in this area are scarce and not stratified by type of HF. We evaluated the performance of current creatinine and cystatin C equations (eGFR creatinine-based equation [eGFRcr], eGFR serum cystatin C-based, and eGFR creatinine-cystatin C equation) compared with measured GFR (mGFR) among patients with HF stratified by ejection fraction.

Calcified nodules (CNs) remain a major challenge in percutaneous coronary intervention (PCI). We sought to compare procedural and clinical outcomes after orbital atherectomy (OA) versus intravascular lithotripsy (IVL)-facilitated PCI in patients with CNs.

The "2025 AHA/ACC/AANP/AAPA/ABC/ACCP/ACPM/AGS/AMA/ASPC/NMA/PCNA/SGIM Guideline for the Prevention, Detection, Evaluation, and Management of High Blood Pressure in Adults" retires and replaces the "2017 ACC/AHA/AAPA/ABC/ACPM/AGS/APhA/ASH/ASPC/NMA/PCNA Guideline for the Prevention, Detection, Evaluation, and Management of High Blood Pressure in Adults."

Doxorubicin cardiomyopathy (DoxCM) remains a significant clinical problem, but its underlying mechanisms remain incompletely understood. Identifying DoxCM mechanisms can lead to therapeutic interventions that improve patient outcomes.

Atrial fibrillation, the most common sustained arrhythmia, affects 59 million individuals worldwide. The transcription factor TBX5 (T-box 5) is essential for normal atrial rhythm. Its inactivation causes loss of atrial cardiomyocyte (aCM) enhancer accessibility, looping, transcriptional identity, and spontaneous atrial fibrillation. TBX5 interacts with CHD4 (chromodomain helicase DNA-binding protein 4), a chromatin remodeling ATPase canonically associated with the NuRD (nucleosome remodeling and deacetylase) repressor complex.

The timing of surgery in asymptomatic severe mitral regurgitation remains controversial. This observational study sought to compare long-term outcomes of early surgery with a conventional treatment strategy in asymptomatic patients with severe mitral regurgitation.

Stalking is one of the most common forms of interpersonal violence, with nearly 1 in 3 women experiencing it in their lifetime. Restraining orders are a legal remedy aimed at protecting women who experience the most severe forms of stalking and interpersonal violence. Previous work has shown associations between experiences of violence and cardiovascular health among women, but little is known about the link between being stalked or obtaining a restraining order and risk of cardiovascular disease (CVD).

Ultraprocessed foods and beverages (UPFs) pose a growing public health challenge. Commonly defined by the Nova system, UPFs are industrially processed products made with additives or ingredients not commonly used in home cooking. Although ultraprocessing or extensive processing can lower cost and improve shelf life, convenience, and taste of certain products, high UPF intake is consistently linked to negative health outcomes. Although mechanisms remain unclear, evidence supports food policies that limit UPF intake while avoiding unintended consequences. Identifying high-risk UPF subgroups is essential to balancing nutritional goals with the need for accessible and appealing food options. Most UPFs overlap with foods high in saturated fat, added sugars, and sodium, which are already targets for cardiometabolic risk reduction. Future priorities include uncovering how UPFs specifically affect cardiometabolic health, refining dietary guidance to discourage nutrient-poor UPFs, and clarifying the impact of UPFs with more favorable profiles. This science advisory reviews current evidence on UPFs and their impact on cardiometabolic health and outlines research needs, regulatory reform, and policy changes needed to affect better dietary intake and overall health.

GRKs (GPCR [G protein-coupled receptor] kinases) are key regulators of GPCR signaling. Because GPCRs are targeted by approximately 40% of clinical drugs, GRKs also represent therapeutic targets for combating cardiovascular diseases. However, the predominant GRK that responds to diabetic heart injury and the underlying mechanisms remain largely unknown.

Coronary artery calcium (CAC) is a strong predictor of cardiovascular outcomes, with patients having high CAC experiencing event rates similar to those in secondary prevention populations. Emerging evidence suggests that patients with extremely high CAC (≥1000) represent a distinct high-risk group. Therefore, this study aims to evaluate the prognostic value of myocardial flow reserve (MFR) in patients with very high CAC.
