周醫生, (醫學博士,加拿大皇家醫學院內外科院士,心臟科醫生),討論如何用CHADS評估心房顫動病人的中風風險

心房顫動atrial fibrillation,在加拿大大概有三十萬人有這個症狀。當你有心房顫動,你中風的機會會增加二至五倍, 所以很重要諮詢你的家庭醫生或心臟科醫生關於心房顫動的治療方法,尤其是減低你中風的機會。當你有心房顫動,你中風的機會增加了二至四倍,所以非常重要評估你中風的機率,而每個人是不一樣的。在加拿大,我們有一個評估中風機會的方案-CHADS 。通常要是你是超過六十五歲,醫生會提議你吃抗凝血劑。要是你少於六十五歲,我們會評估你有沒有心臟衰竭丶高血壓丶糖尿病丶或者是有沒有中風的歷史。要是你有以上的情況,我們會提議你吃抗凝血劑。要是你沒有以上的情況,我們會看你以前有沒有冠心血管疾病丶心臟病丶中風丶或者周邊血管的疾病。要是你有這些問題,我們會建議你吃阿斯匹靈。要是沒有以上的問題,通常是不需要吃阿斯匹靈或者抗凝血劑。其實市面上有兩種抗凝血劑,傳統的抗凝血劑叫沃法令,這種藥我們用了超過三丶四十年。可是吃這種藥需要經常驗血,檢查INR值,而且可能會跟有些食物和藥物產生相互和抗衡作用。這種藥影響流血,引致腦內出血丶顱內出血的機會也比較高。新型抗凝血劑對於食物和其他藥物的相互作用也比較少出血,尤其是顱內出血,或者其他出血引致死亡的機會也會相對減低。新型藥可以一天吃一次或者兩天吃一次。但它的有效時間比較短,所以很重要定時吃藥,不能忘記吃藥。當你有心律不齊,除了要評估你中風的風險和醫治你的症狀,注意日常生活,比如飲食丶健康的體重,要是你不知道正常的體重,你可以諮詢你的醫生丶護士丶藥劑師丶營養師丶運動專家。盡量不要酗酒,男士每天兩杯或以下和女士每天一杯或以下。要是你被診斷患有心律不齊,你可以跟你的家庭醫生討論中風的風險,有沒有需要服藥減低症狀以及衡量有沒有需要吃抗凝血劑。你可以諮詢你的醫生丶專科醫生丶護士丶藥劑師關於抗凝血劑的資料
