电离辐射对心脏影响的研究进展

长期以来，广泛认为心脏长期暴露于高剂量电离辐射可导致心脏损伤。近年来流行病学、实验和临床研究均证实，低剂量电离辐射暴露可通过不同机制造成心血管系统损伤。本综述分析了电离辐射暴露导致的心脏损伤以及潜在心血管疾病风险、综述了目前用于心脏电离辐射损伤检测的非侵入性方法、并提出了预防和减轻放射性心脏损伤的有关措施，从而为心脏电离辐射损伤早期发现和早期干预提供参考依据。

Research progress in effects of ionizing radiation on the heart

It has been recognized that long-term exposure of the heart to high-dose ionizing radiation can result in cardiac injury. Nevertheless, recent epidemiological, experimental, and clinical studies have demonstrated that exposure to low-dose ionizing radiation may also cause cardiovascular injury via various mechanisms. This article reviews the cardiac injury and potential cardiovascular risk caused by ionizing radiation, summarizes the currently available non-invasive approaches used for detecting radiation-induced cardiac injury, and proposes interventions to prevent and alleviate it, with the hope of providing a reference for early identification and interventions for radiation-induced cardiac injury.
