Abstract:
Objective:To analyze the relationship between blood urea nitrogen (BUN)/albumin (ALB) ratio (B/A) and prognosis of patients undergoing percutaneous coronary intervention (PCI) guided by ultrasound before operation.Methods:A total of 116 patients who underwent PCI under the guidance of intra-coronary ultrasound in Xianyang Central Hospital from February 2020 to December 2022 were retrospectively selected as the observation group, and 120 healthy people in the same period were selected as the control group. All patients were followed up for 1 year after surgery, and 116 patients were divided into poor prognosis group ( n=33) and good prognosis group ( n=83), taking major adverse cardiovascular events (MACE) as the end point during follow-up. The levels of BUN and ALB in peripheral blood of all subjects were detected after admission, and B/A was calculated. The basic data, biochemical indexes and B/A of each group were analyzed and compared. The predictive value of preoperative BUN, ALB and B/A on postoperative MACE in patients with PCI guided by intra-coronary ultrasound was analyzed by receiver operating characteristic (ROC) curve. Multivariate logistic regression analysis was used to evaluate the related influencing factors of postoperative MACE in patients with PCI guided by intra-coronary ultrasound. Results:The left ventricular end-diastolic inner diameter (LVEDD), N-terminal B-type natriuretic peptide (NT-proBNP), creatine kinase isoenzyme (CK-MB), BUN and B/A in the observation group were higher than those in the control group, and left ventricular ejection fraction (LVEF) and ALB were lower than those in the control group (all P<0.05). NT-proBNP, CK-MB, BUN and B/A in the poor prognosis group were higher than those in the good prognosis group, and LVEF and ALB were lower than those in the good prognosis group (all P<0.05). ROC curve results showed that the AUC of peripheral blood BUN, ALB and B/A predicting postoperative MACE in patients with PCI guided by intra-coronary ultrasound were 0.833(95% CI: 0.783-0.883), 0.859(95% CI: 0.809-0.909) and 0.922(95% CI: 0.872-0.972). Multivariate logistic regression analysis showed that LVEF [ OR(95% CI)=1.952(1.317-2.895)], NT-proBNP [ OR(95% CI)=2.625(1.643-4.193)], BUN [ OR(95% CI)=3.353(1.922-5.851)], ALB [ OR(95% CI)=3.792(2.049-7.018)] and B/A [ OR(95% CI)=3.277(2.000-5.370)] were all the influencing factors of postoperative MACE in patients undergoing PCI guided by intra-coronary ultrasound ( P<0.05). Conclusions:The level of B/A in patients with PCI guided by intra-coronary ultrasound increased before surgery, and the high level of B/A is a risk factor for postoperative MACE, which can be used as a biological index to evaluate the postoperative MACE in patients with PCI guided by intra-coronary ultrasound.
