EIECC: Early Identification and Evaluation of Cyclophosphamide Cardiotoxicity
Study Details
Study Description
Brief Summary
Hematopoietic stem cell transplantation is an important method for the treatment of hematological diseases and cyclophosphamide is a commonly used chemotherapeutic agent for transplant pretreatment. The incidence of severe cardiovascular events after high-dose cyclophosphamide exposure ranges from 7% to 28% with mortality from 11% to 43%. Thus, an non-invasive, sensitive and reliable method in detecting cardiac function is significant to balance the cardiac risk and the potential cancer treatment benefits. In previous studies, we demonstrated that strain values analyzed by speckle tracking echocardiography decreased significantly after high-dose cyclophosphamide exposure, even though left ventricular ejection fraction remained stable and within normal range. We follow up the hematopoietic cell transplantation patients with cyclophosphamide: to analyze the cut-off values of the parameters of speckle tracking multilayer analysis in predicting early cardiotoxicity induced by cyclophosphamide; to detect the cut-off values of the plasma miRNAs levels in predicting early cardiotoxicity induced by anthracycline.
The purpose of our study is to find out non-invasive, reliable and sensitive echocardiographic parameters and plasma biomarkers for early detection and prediction cyclophosphamide -induced cardiac toxicity and to be helpful to target patients at high risk of cardiotoxicity, who could benefit from closer monitoring or earlier initiation of cardioprotective therapy.

Detailed Description
After obtaining the informed consent of the research subjects, collect the following data of the research subjects: demographic information, clinical symptoms, family history and clinical diagnosis. Patients were tested for troponin, atrial natriuretic peptide, concurrent conventional electrocardiogram, conventional echocardiogram, speckle tracking echocardiography at spots 1 day before cyclophosphamide treatment, 2 days after cyclophosphamide infusion, and 10 days after cyclophosphamide infusion. ethylenediaminetetraacetic acid anticoagulated whole blood were saved and extract the blood cells from the sample bank and freeze them for RNA sequencing. The two-dimensional cardiac ultrasound image acquisition complies with the guidelines of the American Echocardiography Association, and the two-dimensional speckle tracking echocardiography acquisition is 4 cardiac cycles. If a cardiotoxic event occurs during this period, an electrocardiogram, conventional echocardiogram, and speckle tracking echocardiography should be performed within 24 hours.
Analyze the correlation between miRNA and clinical events of cardiotoxicity, and evaluate the predictive threshold of cardiotoxicity in children with high-dose cyclophosphamide chemotherapy.Evaluate the weight of miRNA in predicting cardiac damage, combined with serum biomarkers, construct a model for Predicting the risk of myocardial damage based on speckle tracking echocardiography parameters, serum biomarkers, and miRNA expression.
