How old is your heart?
你的心臟年齡是多少？
Have you ever thought someone looks younger or older than their actual age? Scientists say our organs are just the same.
你有沒有覺得有些人看起來比他們的實際年齡要更年輕或更老？科學傢們說，人體器官也有年齡。
Importantly, the higher your heart age, the higher your risk of having a heart attack or stroke.
然而重要的是，你的心臟年齡越高，患心臟病或中風的風險就越高。
It also increases the risk of certain diseases.
患一些特定疾病的風險也會增高。
dementia
失智癥
chronic kidney disease
慢性腎病
diabetes
糖尿病
There are calculators online that can give us a rough idea of our heart’s age.
網上現在有一種計算工具，可以根據你輸入的各項信息估算心臟年齡。
And doctors use electrocardiograms and blood pressure analysis to get a more accurate snapshot.
醫生可以通過給人們做心電圖和測量血壓來獲取每個人更準確的心臟健康狀況，從而判斷心臟的年齡。
But now, scientists are starting to use AI to analyse MRI scans – picking up the earliest signs of premature ageing that even expert cardiologists would be unlikely to detect.
現在科學傢們開始使用人工智能來分析核磁共振掃描圖像，希望能及時發現心臟過早衰老的最初跡象，通常即便是心臟病專傢也不太可能及時發現這些跡象。
It’s hoped that in the future this AI modelling can show whether premature ageing can be slowed or reversed.
希望未來這種人工智能模型能夠揭示心臟過早衰老這一過程是否可以被減緩或被逆轉。
But can you reduce the risk now?
但現在有哪些方法可以幫你降低心臟過早衰老的風險？
Scientists haven’t figured out yet whether premature ageing is more down to our genetics or lifestyle.
科學傢們尚未弄清楚引起過早衰老的原因究竟是基因還是生活方式。
Genes like the ones associated with muscle elasticity could impact our heart.
比如：與肌肉彈性相關的基因可能會影響我們的心臟健康。
But they’ve identified high blood pressure, smoking, diabetes and obesity as major risk factors for premature heart ageing.
但科學傢們已經確定高血壓、吸煙、糖尿病和肥胖是心臟過早衰老的主要風險因素。
So, following these recommendations can help reduce those risks.
因此，遵循這四條建議有助於降低心臟過早衰老的風險。
Eat well.
健康飲食。
Exercise.
做運動。
Check blood pressure.
測量血壓。
Not smoking.
不吸煙。
