New Scanner Creates Highly Detailed, 3D Images of Blood Vessels in Just Seconds A new scanner can provide three-dimensional (3D) photoacoustic images of millimeter-scale veins and arteries in seconds.

Nobel Prize in medicine goes to two American biologists for work on the discovery of microRNA The 2024 Nobel Prize in physiology or medicine has been awarded to US scientists Victor Ambros and Gary Ruvkun for their work on the discovery of microRNA, a molecule that governs how cells in the body function.

Novel PCSK9 Inhibitor Reduced LDL by 50% Lerodalcibep, a novel, third-generation proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor, reduced low-density lipoprotein cholesterol (LDL-C) by more than 50% after 1 year in patients with or at a high risk for cardiovascular disease (CVD), new phase 3 results showed.

ACC/AHA Issue Updated Atrial Fibrillation Guideline The American College of Cardiology (ACC), the American Heart Association (AHA), the American College of Chest Physicians (ACCP), and the Heart Rhythm Society (HRS) have issued an updated guideline for preventing and optimally managing atrial fibrillation (AF).

AHA Flags Barriers to Women in Interventional Specialties A new scientific statement from the American Heart Association (AHA) addresses barriers to entry and retention of women in interventional vascular fields, including interventional cardiology, interventional radiology, and vascular surgery, and proposes potential solutions.

New Marker of Cardiovascular Risk Discovered in T2D A significant quantity of dysfunctional monocytes appears to indicate poor cardiovascular prognosis in patients with type 2 diabetes.

New Score Predicts Risk for Death on Heart Transplant List Allocation score, called the US candidate risk score (US-CRS), outperformed the current therapy-based 6-status system in rank ordering heart transplant candidates by medical urgency.

Near-Death Experiences During CPR: An Impetus for Better Care If someone has been in cardiac arrest for 10 minutes, the brain is permanently damaged and there's nothing to do, right? Not so according to emerging evidence that suggests that the brain shows signs of electrical recovery for as long as an hour into ongoing cardiopulmonary resuscitation (CPR). This time between cardiac arrest and awakening can be a period of vivid experiences for the dying patient before they return to life — a phenomenon known as "recalled death."

Novel Biomarkers for Aortic Stenosis Identified A new analysis that used plasma proteomics, cardiac imaging, and event surveillance of participants in a longitudinal cohort study identified 52 circulating proteins with significant links to aortic valve (AV) hemodynamics and the risk for AV-related hospitalizations. Two of these biomarkers had particularly robust associations.

Recommendations for magnetic resonance imaging in patients with cardiac implantable electronic devices Over the last several decades, magnetic resonance (MR) imaging has become the diagnostic modality of choice for several conditions, cardiac and non-cardiac. However, MR uses a static magnetic field, gradient magnetic fields and pulsed radiofrequency energy, all of which may interact with metallic and electronic components within the field. As such, patients with cardiac implantable electronic devices (CIEDs) have traditionally been precluded from MR imaging given the potential harm from mechanical force and torque, heating and tissue damage, unwanted myocardial stimulation or electrical reset.
