The risk of having a heart attack while pregnant, giving birth, or during the two months after delivery, continues to increase for American women, a new study finds. As published online July 18 in the Mayo Clinic Proceedings, the study, led by NYU School of Medicine researchers, found that the risk of suffering a heart attack […]
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 […]
South Asians living in the United States are more likely to die of heart conditions caused by atherosclerosis, such as heart attacks and strokes, than East Asians and non-Hispanic whites in the U.S. Clinical experts at Rush University Medical Center reported this finding in a new scientific statement they co-authored that is being published in […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
When electrical waves in the heart run amok in a condition called arrhythmia, sudden death can occur. To save the life of a patient at risk, doctors currently implant a small defibrillator to sense the onset of arrhythmia and jolt the heart back to a normal rhythm. But a thorny question remains: How should doctors […]
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 — […]
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 […]
