In a meta-analysis of 19 studies and more than 2 million patients, the mean prevalence of blood transfusions in contemporary PCI was 2.3%, and patients undergoing PCI who received blood transfusions had a threefold risk for mortality and MACE compared with patients who did not receive transfusions.
Researchers aimed to define the frequency of blood transfusions during PCI and how those transfusions predict clinical outcomes. The analysis included 19 published studies covering 2,258,711 patients who had more than 54,000 transfusions. The primary endpoints were mortality and MACE.
