Abstract:
Objective To evaluate left ventricular global longitudinal strain in endocardium,middle myocardium and epi cardium of patients with breast carcinoma treated with anthracyclines by two-dimensional layered strain technology.Methods Totally 20 breast cancer patients after surgery without chemotherapy (control group) and 32 breast cancer patients who were treated with anthracycline-based chemotherapy were enrolled.The patients treated with chemotherapy were performed transthoracic echocardiography 3 months and 5 months after chemotherapy.Global longitudinal strain (GLS) and each segment (apex,basis and media section) strain in 3 myocardial layers (endocardium,middle myocardium and epicardium) were measured by EchoPAC software.Results Compared with control group,with the extension of chemotherapy cycle,GLS of 3 myocardial layers reduced in breast carcinoma patients treated with anthracyclines (all P＜0.05),but left ventricular ejection fraction (LVEF) had no statistical difference (P＞0.05).Compared with control group,each layer of each segment of longitudinal strain decreased in breast carcinoma patients treated with anthracyclines (all P＜0.05),except the apex section.Conclusion Longitudinal layer-specific strain technology can accurate assess whole and local systolic function of 3 myocardial layers of left ventricular,which can provide a new method for judging myocardial damage.
