您的氣喘、心口痛原因是甚麼？？您有二尖瓣倒流嗎？

甚麼是二尖瓣倒流？^1,2

二尖瓣是心臟的其中一組瓣膜，位於左心房及左心室之間。在正常的情況下，二尖瓣會讓血液由左心房流往左心室，再經過主動脈流向身體不同的器官。但如果二尖瓣不能完全閉合，流經的血液就會往相反方向倒流，這就是「二尖瓣倒流」。

二尖瓣倒流會加重心臟、肺部及其他器官的負荷，長遠會導致心臟衰竭，亦可能會引致心跳不規律、中風，甚至猝死。

二尖瓣倒流其實並不算是難治的心臟疾病，但其危險之處在於病徵不明顯，患者容易忽視症狀而未能及早求醫。不少患者，尤其是年長者，更會誤以為腳腫、氣喘等症狀都是正常的老化，錯過治療的良機。

由此可見，如能及早發現問題，醫生就可根據您的情況以制訂治療或控制病情的方案。
