HDL-free cholesterol influx into macrophages and transfer to LDL correlate with HDL-free cholesterol content.

J Lipid Res

November 2024

Department of Medicine, Houston Methodist, Houston, TX, USA; Department of Medicine, Weill Cornell Medicine, New York, NY, USA. Electronic address:

High-density lipoprotein (HDL)-free cholesterol (FC) transfers to other lipoproteins and cells, the former by a spontaneous mechanism and the latter by both spontaneous and receptor-mediated mechanisms. Macrophages are an important cell type in all stages of atherosclerotic cardiovascular disease (ASCVD), and the magnitude of FC efflux from macrophages to HDL, a metric of HDL function, inversely associated with several metrics of ASCVD. Very high plasma HDL concentrations are associated with increased all-cause and ASCVD mortality, suggesting that the reverse process, FC influx from HDL into macrophages, is atherogenic.

Over a decade of randomized controlled trial data demonstrate excellent outcomes with transcatheter aortic valve replacement or surgical aortic valve replacement for patients with symptomatic severe aortic stenosis regardless of surgical risk. The 2020 American College of Cardiology/American Heart Association guidelines recommend both options for low-risk AS patients aged 65 to 80 years. However, the fastest growing population of patients receiving transcatheter aortic valve replacement in the United States is <65 years old, with little data to support the practice.

Polygenic Risk Scores and Extreme Coronary Artery Calcium Phenotypes (CAC=0 and CAC≥1000) in Adults ≥75 Years Old: The ARIC Study.

Circ Cardiovasc Imaging

November 2024

Johns Hopkins Ciccarone Center for the Prevention of Cardiovascular Disease, Johns Hopkins University School of Medicine, Baltimore, MD (O.D., A.C.R., Z.A.D., S.P.W., M.B.M., M.J.B.).

Article Synopsis
  • The study examines the relationship between polygenic scores for coronary heart disease (CHD) and coronary artery calcium (CAC) in adults aged 75 and older, suggesting that genetic factors may influence arterial aging beyond traditional risk factors.
  • Researchers analyzed data from 1,865 participants, finding that higher polygenic CHD risk scores were associated with significantly lower odds of having no CAC and much higher odds of having high CAC levels.
  • Each standard deviation increase in the polygenic risk score corresponded to a 78% increase in CAC scores, indicating a strong link between genetic predisposition and arterial health in older adults.

The future of hypertension pharmacotherapy: Ongoing and future clinical trials for hypertension.

Curr Probl Cardiol

January 2025

Section of Cardiology, Department of Medicine, Baylor College of Medicine, Houston, TX, USA; Section of Cardiovascular Research, Baylor College of Medicine, Houston, TX, USA.

Hypertension is among the most prevalent diagnoses across the world and increases the risk of many serious health problems, such as stroke, heart disease, and kidney disease. Pharmacological approaches to treat hypertension are often required and reduce blood pressure through mechanisms such as vasodilation, inhibition of the renin-angiotensin-aldosterone pathway, and increased urine output to reduce blood volume, among other mechanisms. Further research is ongoing to find novel pathways and mechanisms to treat hypertension, which we summarize in this review.

Article Synopsis
  • The study explored the impact of residual transmitral mean pressure gradient (TMPG) after mitral transcatheter edge-to-edge repair (M-TEER) on patient outcomes, focusing on all-cause mortality and hospitalizations related to heart failure.
  • Higher baseline TMPG was found to predict increased residual TMPG post-procedure, with patients in the highest quartile experiencing significantly worse outcomes, including higher risks of mortality and heart failure hospitalization over three years.
  • The findings suggest that efforts should be made to minimize residual TMPG after M-TEER, particularly in patients with primary mitral regurgitation (MR).

Sci Rep

November 2024

Center for Computational and Precision Health (C3PH), DeBakey Heart and Vascular Center, Houston Methodist, Houston, TX, 77030, USA.

Article Synopsis
  • Researchers aimed to find a screening method using computed tomography calcium scoring (CTCS) to assess the risk of heart failure (HF) in patients, particularly focusing on those with type 2 diabetes.
  • They analyzed CTCS scans from nearly 2,000 patients and applied deep learning to create models that predict HF risk based on radiomic features of epicardial adipose tissue (EAT) and calcifications.
  • The study found that CTCS-based models, especially those using fat-omics for non-diabetic patients and calcium-omics for diabetic patients, significantly outperformed traditional clinical prediction methods in forecasting incident HF.

September 2024

MedTech Epidemiology and Real-World Data Sciences, Johnson & Johnson, New Brunswick, New Jersey.

Article Synopsis
  • A study investigated the impact of timing on ablation procedures for patients with atrial fibrillation (AF) and heart failure (HF), using data from the Optum Clinformatics database from 2013 to 2022.
  • Patients were divided into two groups: early ablation (within 6 months of AF diagnosis) and late ablation (6-24 months post-diagnosis), assessing various outcomes over 24 months.
  • Results showed that early ablation significantly reduced the rate of AF-related complications, including lower risks for AF recurrence, repeat ablation, and antiarrhythmic drug use compared to late ablation, although no significant differences were found in AF-related hospitalizations or electrical cardioversion.
