Value of Cervical Vascular Ultrasound in Predicting Adverse Vascular Events in Patients with Acute Myocardial Infarction After Surgery
Objective:To investigate and analyze the value of cervical vascular ultrasound in predicting adverse vascular events after acute myocardial infarction(AMI).Methods:79 patients with AMI treated and treated in Department of Ultrasound,Tianjin Baodi District People's Hospital from June 2019 to December 2021 were selected.All patients were given cervical vascular ultrasonography to follow up the prognosis of patients,record the occurrence of major adverse cardiovascular events(MACE),and analyze the predictive value.Results:79 patients were followed up to February 1,2023,with an average follow-up time of(17.22±1.35)months.The incidence of adverse cardiovascular events(MACE group)was 17.7%(6 cases of recurrent myocardial infarction,4 cases of heart failure,1 case of cardiac death,and 3 cases of revascularization).There was no significant difference in the arterial resistance index(RI)between the two groups(P>0.05),the pulse index(PI)in MACE group was significantly higher than that in non-MACE group(P<0.05),and the peak systolic flow velocity(Vs)and end-diastolic flow velocity(Vd)in MACE group were significantly lower than those in MACE group(P<0.05).The receiver operating characteristic(ROC)curve analysis showed that the maximum area under the curve for predicting postoperative MACE in AMI patients using neck vascular ultrasound was 0.840,with a sensitivity of 86.54%and a specificity of 78.25%.Conclusion:The incidence of major adverse cardiovascular events is relatively high in patients with acute myocardial infarction,which is usually accompanied by abnormal ultrasonic blood flow in neck vessels.Cervical vascular ultrasound has great value in predicting postoperative MACE in AMI patients.
