Giving extra blood to anemic sufferers after a coronary heart assault could save lives, in response to a Rutgers Well being–led research.
The research, printed in NEJM Proof, affirms analysis carried out in 2023 that advised mortality fee or recurrent coronary heart assaults had been extra frequent in anemic sufferers who acquired much less blood.
Jeffrey L. Carson, provost and Distinguished Professor of drugs at Rutgers Robert Wooden Johnson Medical College, led each research. The 2023 trial – known as MINT (myocardium infarction and transfusion) – checked out transfusions in anemic sufferers following a coronary heart assault.
