Transfusion‐associated circulatory overload and high blood pressure: A multicentre retrospective study in Japan

“…Similarly, the following information about the patients was collected: age group, weight, brain natriuretic peptide (BNP) level and estimated glomerular filtration rate as surrogate markers of congestive heart failure (CHF) and chronic kidney disease (CKD), respectively, comorbidities, complications, outcomes of reactions (1-year survival and comorbidities), symptoms prior to transfusion, duration from the start of transfusion to the onset of initial symptoms, symptoms or physical findings at the onset of a reaction and during the course of the treatment, amount and type of blood products used, rate of transfusion, findings on chest x-ray, BNP level following the onset of symptoms, efficacy of treatments, and changes in vital signs, including blood pressure, pulse rate, body temperature, and oxygen saturation, prior to transfusion and up to 12 h after transfusion. The diagnosis of TACO was made by primary physicians and transfusion medicine teams based on both the Japanese Ministry of Health, Labour and Welfare Research Group guidelines [10], and the International Society of Blood Transfusion Working Party July 2011 diagnostic criteria [11]. Furthermore, a revised criteria established in 2019 was applied to subsequent analysis [12].The above information was also collected from patients whose blood pressure (either systolic or diastolic) increased by at least 30 mmHg following transfusion.…”
