NHLBI-funded researchers at Brigham and Women's Hospital found that a genetic risk score identified individuals at increased risk for cardiovascular death or a heart attack, both in individuals with and without known coronary disease, with individuals in the highest genetic risk score group having more than a 70 percent increase in the risk of cardiovascular death or a heart attack compared to the lowest risk group

NHLBI Media Availability: NHLBI Researchers Discover Never-Before-Seen Mode of Viral Transmission
WHAT: NHLBI-funded researchers have discovered a novel means by which viruses spread between cells: multiple polioviruses, a type of enterovirus, travel together within a membrane-enclosed sac, arriving together at a cell they then infect. This finding revises a central tenet of virology that viruses behave as independent infectious agents.
Study shows that iron supplementation after blood donation shortens hemoglobin recovery time
A National Institutes of Health-funded study comparing low dose iron supplementation to no supplementation in blood donors found that supplementation significantly reduced the time to recovery of post-donation lost iron and hemoglobin—an iron-rich protein that carries oxygen in red blood cells throughout the body.
The results of the Hemoglobin and Iron Recovery Study (HEIRS), supported by NIH’s National Heart, Lung, and Blood Institute (NHLBI), will appear Feb. 10 in the Journal of the American Medical Association.
