A new study led by Rutgers Health researchers indicates that providing more blood transfusions to anemic patients following a heart attack could potentially reduce mortality rates.
Rutgers University researchers, led by Jeffrey L. Carson, have conducted a study published in NEJM Evidence that suggests giving more blood transfusions to anemic patients after a heart attack may save lives. This study builds on previous research from 2023, the MINT (myocardium infarction and transfusion) trial, which indicated a higher mortality rate and recurrence of heart attack s in anemic patients who received fewer transfusions.
The recent study combined data from four clinical trials involving 4,311 patients with heart attacks and low blood counts. These trials compared the frequency of death at 30 days or recurrent heart attacks in patients who received more versus fewer blood transfusions. While the analysis didn't definitively prove that fewer transfusions increased the risk of death or heart attack at 30 days, it did suggest a higher risk of death at six months in patients who received less blood. The original trials included a high percentage of patients with pre-existing conditions such as previous heart attacks, heart failure, diabetes, or kidney disease. The average age of participants was 72, with 45% being women
