Clinical Trial 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.
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.
