Abstract:
Objective To evaluate the myocardial microcirculation function of patients with acute myocardial infarction(AMI)after treatment with myocardial contrast-enhanced ultrasound combined with albumin(ALB)and lipoprotein a[Lp(a)].Methods Ninety-six patients with AMI admitted to our hospital from January 2022 to September 2023 were selected.According to myocardial microcirculation function after treatment,they were divided into a normal function group(56 cases)and a dysfunction group(40 cases).major cardiovascular adverse events were compared between the two groups.major cardiovascular adverse events(MACE),the plateau peak intensity of myocardial contrast ultrasound parameters(A value),the rise rate of microbubble reperfusion(β value),myocardial blood flow(A value×β value),and serum ALB and Lp(a)levels after 48h of treatment were different,so as to determine the evaluation value of myocardial contrast ultrasound,ALB and Lp(a)on myocardial microcirculation function in AMI patients after treatment.Results In the dysfunction group,the parameters A,β,A×β,and serum ALB level,Lp(a)was higher than that in the normal function group(P＜0.05).A,β,A×β,ALB were positively correlated with cardiac function,and Lp(a)was negatively correlated with cardiac function(P＜0.05).CEUS combined with ALB and Lp(a)evaluated the efficacy of myocardial microcirculation in patients with AMI(P＜0.05).The incidence of MACE was higher in the functional group than in the normal functional group(P＜0.05).Conclusion Myocardial contrast-enhanced ultrasound can early evaluate the myocardial microcirculation function in patients with acute myocardial infarction after treatment,and combined with serum ALB and Lp(a),it can improve diagnostic efficacy.
