New Target for Treating Heart Failure Identified by Penn Medicine Researchers

Changes in cellular struts called microtubules (MT) can affect the stiffness of diseased human heart muscle cells, and reversing these modifications can lessen the stiffness and improve the beating strength of these cells isolated from transplant patients with heart failure, found researchers from the Perelman School of Medicine at the University of Pennsylvania. This Nature […]

Individuals with HIV at Higher Risk for Heart Disease

A review of more than 80 studies reveals that changes in the immune cells of people with human immunodeficiency virus (HIV) infection may increase their risk of cardiovascular disease (CVD). The review is published in the journal Physiology. Combination antiretroviral therapy (cART) consists of a “cocktail” of several drugs that work together to reduce the amount of detectable […]

New MRI Technology Could Help Doctors Detect Heart Disease, Other Inflammatory Diseases with Better Accuracy

Doctors might be able to better detect any disease or disorder that involves inflammation thanks to a new MRI imaging technology co-developed by faculty at Binghamton University, State University of New York. Amber Doiron, research assistant professor in the biomedical engineering department at Binghamton University, along with a fellow researcher at Temple University, has developed […]

Mitochondrial Protein in Cardiac Muscle Cells Linked to Heart Failure, Study Finds

Reducing a protein found in the mitochondria of cardiac muscle cells initiates cardiac dysfunction and heart failure, a finding that could provide insight for new treatments for cardiovascular diseases, a study led by Georgia State University has shown. The researchers discovered that reducing an outer mitochondrial membrane protein, FUN14 domain containing 1 (FUNDC1), in cardiac […]

Re-Interventions Are Common in Long-Term Survivors of Childhood Heart Operations

Among patients who undergo childhood heart surgery for the severe birth defect single-ventricle disease, two-thirds of survivors require a surgical or catheter-based procedure within 20 years. Pediatric cardiology researchers note that doctors should counsel families about the likelihood of re-interventions. “Unfortunately, for many patients, the Fontan is not the final intervention,” said study leader Andrew […]

Stem Cell Breakthrough Unlocks Mysteries Associated With Inherited And Sometimes Lethal Heart Conditions

Using advanced stem cell technology, scientists from the Icahn School of Medicine at Mount Sinai have created a model of a heart condition called hypertrophic cardiomyopathy (HCM) — an excessive thickening of the heart that is associated with a number of rare and common illnesses, some of which have a strong genetic component. The stem […]

George Washington University Researchers Receive $1.6 Million to Improve Cardiac Function During Heart Failure

Researchers at the George Washington University (GW) received $1.6 million from the National Heart, Lung, and Blood Institute to study a heart-brain connection that could help the nearly 23 million people suffering from heart failure worldwide. The four-year project will study ways to restore parasympathetic activity to the heart through oxytocin neuron activation, which could […]

Mouse Study Links Heart Regeneration to Telomere Length

Researchers at the Spanish National Center for Cardiovascular Research have discovered that the ends of heart muscle cell chromosomes rapidly erode after birth, limiting the cells’ ability to proliferate and replace damaged heart tissue. The study, “Postnatal telomere dysfunction induces cardiomyocyte cell-cycle arrest through p21 activation,” which will be published online May 30 in The […]

Study Shows How Different People Respond to Aspirin — an Important Cardioprotective Drug

Researchers have learned new information about how different people respond to aspirin, a globally prescribed drug in cardioprotection. The research team, led by scientists at Cardiff University in the United Kingdom and including representatives from the University of Alabama at Birmingham and the University of Colorado, identified more than 5,600 lipids — or fats — […]

In Child Heart Patients, a Novel Approach Improves Symptoms of Hazardous Lymph Blockage

Pediatric researchers have devised an innovative, safe and minimally invasive procedure that helps relieve rare but potentially life-threatening airway blockages occurring in children who had surgery for congenital heart defects. The physician-researchers developed new imaging tools and used minimally invasive catheterization techniques to treat plastic bronchitis, a condition in which abnormal circulation causes lymphatic fluid […]
