放射治疗与心脏损伤

Radiotherapy and cardiac injury

放射治疗中电离辐射可能对心脏的各个结构,包括心包、心肌、瓣膜、传导系统和冠状动脉等造成损伤.放射性心脏损伤在心肌酶、灌注显像、心电图、应变率成像等方面均有异常表现.

During radiotherapy, ionizing radiation can damage some structures of the heart, including pericardium, myocardium, cardiac valve, conducting system, and coronary artery. Radiation-induced cardiac injury can manifest as abnormalities in many aspects including myocardium enzymes, perfusion imaging, electrocardiogram, strain rate imaging.
