The spike protein (foreground) enables the virus to enter and infect human cells. On the virus model, the virus surface (blue) is covered with spike proteins...
ELIFE A process that releases iron in response to stress may contribute to heart failure, and blocking this process could be a way of protecting the heart, suggests a study in mice published today in eLife. People with heart failure often have an iron deficiency, leading some scientists to suspect that problems with iron processing in...
by Boston University School of Medicine Credit: Pixabay/CC0 Public Domain Atrial fibrillation (AF) is associated with a higher risk of complications including ischemic stroke, cognitive decline, heart failure, myocardial infarction and death. AF frequently is undetected until complications such as stroke or heart failure occur. While the public and clinicians have an intense interest in detecting AF earlier,...
TEMPLE UNIVERSITY HEALTH SYSTEM (Philadelphia, PA) – Like a failing fuel pump that causes a loss of engine power in a car, a diseased heart can take a serious toll on the body’s performance. For some patients, tasks like walking up a flight of stairs or walking across a room eventually turn into exhausting endeavors....
by Johns Hopkins University School of Medicine Two hearts, a normal on the left and one with heart failure with preserved ejection fraction (HFpEF) on the right. The heart with HFpEF has a thicker, stiffer left ventricular wall and therefore, less room in the ventricle chamber to fill with an adequate amount of blood to be...
AMERICAN HEART ASSOCIATION DALLAS, Nov. 13, 2020 — Patients who were hospitalized with acute heart failure and had iron deficiency were less likely to return to the hospital if given intravenous iron replacement, according to late-breaking research presented today at the American Heart Association’s Scientific Sessions 2020. The virtual meeting is Friday, November 13 – Tuesday, November...
An analysis of COVID-19 testing in the Baltimore-Washington metropolitan area of the United States found that Latinx people were around three times as likely to test positive, compared with any other ethnic or racial group. All data and statistics are based on publicly available data at the time of publication. Some information may be out...
DALLAS, July 13, 2020 — Women taking beta blockers for hypertension with no prior history of cardiovascular disease (CVD) have a nearly 5% higher risk for heart failure than men when they present to hospital with acute coronary syndrome, according to new research published today in Hypertension, an American Heart Association journal. Beta blockers are...
NEW YORK INSTITUTE OF TECHNOLOGY Biomedical experts believe that half of heart failure patients likely have low levels of the thyroid hormone T3 in their cardiac tissue. While heart failure symptoms are commonly attributed to cardiovascular conditions like coronary artery disease and high blood pressure, a growing number of studies suggest that low cardiac T3...
