This article mainly focuses on the perioperative application of novel inflammatory biomarkers in cardiovascular surgery undergo CPB.Methods: Patients were divided into CPB group and non-CPB group according to whether they underwent CPB during cardiovascular surgery. The novel inflammatory biomarkers and clinical results were recorded. Neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), platelet × neutrophil/lymphocyte ratio (SII) and monocyte × platelet × neutrophil/lymphocyte ratio (PIV) were calculated. Primary outcomes were perioperative prognosis between CPB group and non-CPB group.Results: A total of 332 patients were initially included in the study. Before PSM, there were 96 patients in the CPB group and 236 patients in the non-CPB group. After PSM, there were 58 patients in the both groups. Compared with the non-CPB group, the CPB group had a higher proportion of intraoperative transfusion of blood products (63.79% vs 6.90%, P<0.001), both red blood cells (58.62% vs 3.45%, P<0.001) and plasma (41.38% vs 1.72, P<0.001), a higher drainage fluid within 24h (380[200,550] vs 200[24,330], ml P=0.002), and required longer mechanical ventilation time (14.
