摘 要:鐵是一種雙面元素,鐵穩態的紊亂對部分組織有害。研究表明心臟是受鐵代謝紊亂影響的主要器官之一。鐵代謝障礙無論是缺乏還是超載,都與心血管疾病的發生率和死亡率增加有關。鐵蛋白是研究鐵狀態的唯一指標,被認為是診斷鐵狀態的最佳單一測定。就目前研究結果來看,多種心血管疾病與鐵代謝紊亂有關,如冠心病、心力衰竭、心肌病、阿霉素導致的心肌損傷及心肌缺血再灌注。明確鐵代謝紊亂引起細胞損傷的機制,并進一步研究鐵蛋白與鐵代謝紊亂所引起的心血管疾病的相關性,可以為臨床上提供便捷、準確的檢測方法,并可指導臨床治療。

Abstract:Iron is a double-sided element, and the disorder of iron homeostasis is harmful to some tissues. Studies have shown that the heart is one of the major organs affected by iron metabolism disorders. Iron metabolism disorders, whether lacking or overloading, are associated with an increased incidence of cardiovascular disease and mortality. Ferritin is the only indicator of iron status and is considered to be the best single assay for diagnosing iron status. According to the current research results, a variety of cardiovascular diseases are associated with iron metabolism disorders, such as coronary heart disease, heart failure, cardiomyopathy, myocardial damage caused by doxorubicin, and myocardial ischemia-reperfusion. To clarify the mechanism of cell damage caused by iron metabolism disorder, and further study the correlation between ferritin and cardiovascular diseases caused by iron metabolism disorder, it can provide a convenient and accurate detection method for clinical, and can guide clinical treatment.

鐵不僅參與血紅蛋白和紅細胞的生成,還是氧運輸和儲存的重要組成部分,同時鐵還是部分酶系統和代謝過程的一部分,然而鐵是一種雙面元素,鐵穩態的紊亂對部分組織有害。缺鐵主要與飲食攝入不足、女性圍絕經期出血以及非甾體抗炎藥引起的消化道出血等有關,而鐵超載是由于腸道吸收增加、胃腸外給藥或飲食攝入增加導致不同器官中過量鐵累積。心臟是受鐵代謝紊亂影響的主要器官之一。鐵代謝紊亂,無論是缺乏還是超載,都與心血管疾病發病率增加和死亡率增加有關[1-3]。從目前的研究結果看,嚴重的鐵超載與心臟損傷有關,而缺鐵與心衰患者的預后不良有關。……
