Atherosclerosis
Conditions
Brief summary
We are preparing to initiate a clinical trial involving Ferumoxytol for magnetic resonance-enhanced imaging in patients with atherosclerosis. The aim of this study is to assess the safety and effectiveness of Ferumoxytol for magnetic resonance angiography in patients with atherosclerosis.
Detailed description
In this study, the safety of Ferumoxytol as an MR imaging contrast agent will be assessed by monitoring vital signs and laboratory parameters such as complete blood count, urinalysis, and liver and kidney function tests before and after administration of Ferumoxytol. Following the injection, all patients will undergo two MRI scans at different time intervals, ranging from 0 to 15 hours and from 24 to 48 hours. Within one week prior to the injection, patients will undergo standard laboratory tests as part of their routine clinical assessment, and the pre-administration lab results will be documented. This study will prospectively enroll patients with atherosclerosis, and Ferumoxytol-enhanced MRA imaging will be performed on all patients to investigate the diagnostic utility of Ferumoxytol as an MR imaging contrast agent.
Interventions
Observe the injection site for skin invagination, rash, or urticaria during injection. Patients and their relatives were asked about any subjective adverse events before, during, and after drug injection, and all adverse events were recorded on the case report forms, and adverse events were scored according to the Common Terminology Criteria for Adverse Events (CTCAE) from Grade 1 mild to Grade 5 death, Observe the vital signs of patients. Patients undergoing MRI underwent electrocardiogram (ECG) monitoring before and within 60 minutes after ferumoxytol administration, specifically including: biochemical panel, iron metabolism, liver and kidney function, cytokines, blood routine, urine routine, 24-hour urine volume, glycosylated hemoglobin and so on. All patients received a total of 3 blood and urine collections at 7 days before injection, 48 hours after injection, 1month to 3months after injection.
