由我們出世一刻起，心臟便不辭勞苦工作，將血液送至全身，沒有休息的一刻。656Please respect copyright.ＰＥＮＡＮＡspl8MhHxl6

你又有沒有想過，心臟究竟係「食咩大㗎呢」?656Please respect copyright.ＰＥＮＡＮＡ49hgan0JXH
656Please respect copyright.ＰＥＮＡＮＡBzdtBOjBk9
(圖2)有科學家為了解答這個問題，找來110個病人(87個心臟正常，23個心臟出現問題)，請示測試者禁食一晚，然後再進行全身麻醉。656Please respect copyright.ＰＥＮＡＮＡvVIL7xUheT
656Please respect copyright.ＰＥＮＡＮＡeMGWmzMzkV
656Please respect copyright.ＰＥＮＡＮＡMWTHYzLce5
在麻醉期間的1小時裡，分別抽取對應部份血管的血液，從而計算出心臟及腳部的新陳代謝狀況(Ref1)。656Please respect copyright.ＰＥＮＡＮＡtqj48VZ8mf
656Please respect copyright.ＰＥＮＡＮＡfbEgd7m7gp
(圖3)綜合所有證據顯示，心臟同腳部均會大量吸收Ketone Bodies，Acetate及Glutamate。656Please respect copyright.ＰＥＮＡＮＡADpgu6Dfxp

有趣的是，腳部會選擇性地吸收飽和脂肪酸，而放出非飽和脂肪酸，656Please respect copyright.ＰＥＮＡＮＡUvoNYHYqYu
但心臟莫論飽和與否均會全數吸收，其中脂肪酸更成為了它能量來源70%有多。656Please respect copyright.ＰＥＮＡＮＡ0QE7v2XAGa
656Please respect copyright.ＰＥＮＡＮＡvbHdLUKViJ
某程度上可以說心臟是「食脂肪大的」。656Please respect copyright.ＰＥＮＡＮＡ7ZPxXK0aXO
656Please respect copyright.ＰＥＮＡＮＡsqc8IOH6Ma
另外，心臟同腳部均有釋放氨基酸的跡象，顯示細胞的蛋白質一直處於分解狀態，而心臟其速度比腳部快10倍有多。656Please respect copyright.ＰＥＮＡＮＡy1I3LXiABU
656Please respect copyright.ＰＥＮＡＮＡR9oIZapf9Y
對比健康心臟及心臟出現問題的病人，出現問題的心臟會吸取更多的Ketone Bodies及增加氨基酸的釋放數量。656Please respect copyright.ＰＥＮＡＮＡCtFTdLiBFA
656Please respect copyright.ＰＥＮＡＮＡRM1f5JWYpH
究竟吸取更多的Ketone Bodies和增加氨基酸釋放量是為了阻擋心臟出現進一步惡化，還是因為出現問題所致而成，這方面還需要進一步的研究。656Please respect copyright.ＰＥＮＡＮＡILxYYbaPGU
