They are a game-changer.
A recent study published in NEJM Evidence suggests that blood transfusions may improve survival rates for heart attack patients who also suffer from anemia. The research indicates that anemic individuals who received more transfusions had a slightly lower risk of dying within six months after a heart attack compared to those who received fewer transfusions.
Dr. Jeffrey Carson, the lead researcher and chair of general internal medicine at Rutgers Robert Wood Johnson Medical School, explained that the findings suggest that providing more blood to anemic patients following a heart attack could save lives. Anemia, which is common among heart attack patients, impairs the blood’s ability to deliver sufficient oxygen throughout the body, which can complicate recovery.
While blood transfusions may increase oxygen delivery to the heart, improving the chances of survival, they also come with potential risks, such as infection or fluid buildup. To investigate the benefits and risks of transfusions, researchers analyzed data from four clinical trials, which included over 4,300 heart attack patients with anemia.
The study showed that 9.3% of patients who received fewer transfusions died within 30 days of their heart attack, compared to 8.1% of those who received more. Furthermore, the incidence of heart-related deaths was lower among those who received more blood, with 3.7% versus 5.5% in the group that received fewer transfusions.
Although the study suggests a potential benefit from additional transfusions, the researchers caution that the main results were not statistically significant, and the findings do not definitively prove that more transfusions are always beneficial for heart attack patients with anemia.
