• Sleep Apnoea After a Heart Attack or Stroke: Why Screening Matters

Often it's the partner who notices first. "He snores like a freight train, then goes quiet, and then gasps." "She's exhausted all day no matter how early she goes to bed." After a heart attack or stroke, those observations deserve more attention than they usually get.

Here is the short answer. Sleep apnoea, repeated pauses in breathing during sleep, is very common after a heart attack or stroke and often goes undiagnosed. In stroke patients, about 72% have some sleep-disordered breathing and 38% have moderate or worse sleep apnoea. A simple questionnaire and a home sleep test can identify it, and treatment improves sleepiness, mood and quality of life.

简短的答案： 往往是伴侣最先注意到：「他打鼾像火车，然后突然安静，接着猛地一喘」「她不管多早睡，白天都累得不行」。心梗或卒中后，这些观察值得比通常更多的关注。睡眠呼吸暂停——睡眠中反复出现的呼吸停顿——在心梗或卒中后非常常见，却常被漏诊；卒中患者中约 72% 有一定程度的睡眠呼吸障碍，38% 为中度以上。简单的问卷和居家睡眠检测就能发现它，治疗能改善困倦、情绪和生活质量。

What is sleep apnoea, and why does it matter for the heart and brain?

In obstructive sleep apnoea, the airway collapses repeatedly during sleep. Each pause drops blood oxygen, jolts the nervous system awake and spikes blood pressure and heart rate, sometimes dozens of times an hour. In central sleep apnoea, more common in heart failure and after some strokes, the brain intermittently stops signalling the body to breathe.

Night after night, that pattern adds stress to the cardiovascular system. Sleep apnoea is linked to high blood pressure that's hard to control, atrial fibrillation, poorer sleep quality and daytime fatigue. It also feeds the shared root of oxidative stress and inflammation that heart and stroke recovery depend on calming (see one inflammation, three hearts).

什么是睡眠呼吸暂停，为什么关系到心脏和大脑： 阻塞性睡眠呼吸暂停是睡眠中气道反复塌陷，每次停顿都会降低血氧、惊醒神经系统、使血压和心率骤升，有时一小时几十次。中枢性睡眠呼吸暂停在心衰和部分卒中后更常见，是大脑间歇性停止发出呼吸信号。日复一日，这一模式给心血管系统增加负担：睡眠呼吸暂停与难以控制的高血压、房颤、睡眠质量差和白天疲劳相关，也助长心脏和卒中康复需要平息的氧化应激与炎症这一共同根源。

How common is sleep apnoea after a heart attack or stroke?

Very. In a meta-analysis of stroke and TIA patients, about 72% had some degree of sleep-disordered breathing and about 38% had moderate or worse sleep apnoea (Johnson & Johnson, Journal of Clinical Sleep Medicine, 2010). Rates are also high in people with coronary artery disease, heart failure and atrial fibrillation.

Yet most cases are never diagnosed. In the general population, an estimated 80% or more of people with moderate to severe obstructive sleep apnoea don't know they have it (Young et al., Sleep, 1997). After a cardiac event or stroke, symptoms like fatigue and poor concentration are easily blamed on recovery itself (see post-stroke fatigue).

心梗或卒中后睡眠呼吸暂停有多常见： 非常常见。卒中和 TIA 患者的荟萃分析中，约 72% 有一定程度的睡眠呼吸障碍，约 38% 为中度以上（J Clin Sleep Med 2010）；冠心病、心衰和房颤患者中比例也很高。但大多数从未被诊断：一般人群中估计 80% 以上的中重度阻塞性睡眠呼吸暂停患者不知道自己患病（Sleep 1997）。心脏事件或卒中后，疲劳和注意力差很容易被归咎于康复本身。

Signs of sleep apnoea: a simple screening checklist

The STOP-Bang questionnaire, developed in Toronto, is a widely used eight-question screen (Chung et al., Anesthesiology, 2008). Count one point for each "yes":

• Snoring loudly

• Tired, sleepy or fatigued during the day

• Observed pauses in breathing, choking or gasping during sleep

• Pressure: high blood pressure, or being treated for it

• BMI over 35

• Age over 50

• Neck circumference over 40 cm

• Gender: male

A higher score means a higher likelihood of obstructive sleep apnoea, and many heart and stroke patients will score at least three just from age and blood pressure. That's not a diagnosis, but it's a good reason to ask your doctor about a sleep test. Other clues include morning headaches, waking to urinate several times a night and low mood.

睡眠呼吸暂停的征兆：简单筛查清单： 源自多伦多的 STOP-Bang 问卷是广泛使用的 8 题筛查工具（Anesthesiology 2008），每个「是」计 1 分：大声打鼾；白天疲倦或犯困；被观察到睡眠中呼吸暂停、呛咳或喘气；高血压或正在治疗高血压；BMI 超过 35；年龄超过 50 岁；颈围超过 40 厘米；男性。分数越高，阻塞性睡眠呼吸暂停可能性越大，很多心脏和卒中患者仅凭年龄和血压就至少 3 分。这不是诊断，但足以成为询问睡眠检测的理由。其他线索包括晨起头痛、夜里多次起夜和情绪低落。

How is sleep apnoea diagnosed?

Diagnosis is simpler than many people expect. For most adults with suspected obstructive sleep apnoea, a home sleep apnoea test, a small device worn overnight in your own bed, is enough. Some people, including those with heart failure, significant lung disease or suspected central sleep apnoea, may need an overnight study in a sleep lab. Your family doctor, cardiologist or neurologist can refer you; ask whether it's covered in your province or by your plan.

如何诊断睡眠呼吸暂停： 诊断比很多人想的简单：多数疑似阻塞性睡眠呼吸暂停的成人，用居家睡眠检测即可——在自己床上戴一晚小型设备。部分人（包括心衰、明显肺病或疑似中枢性睡眠呼吸暂停者）可能需要在睡眠实验室过夜检查。家庭医生、心脏科或神经科医生都可以转介，可询问所在省份或保险是否覆盖。

What treatment can, and can't, do

The main treatment for obstructive sleep apnoea is CPAP, a mask that keeps the airway open with gentle air pressure. Alternatives include oral appliances, positional therapy and weight loss where relevant.

It's worth being honest about the evidence. In the SAVE trial of 2,717 people with cardiovascular disease and sleep apnoea, CPAP did not reduce heart attacks, strokes or cardiovascular deaths overall, although many participants used it for only a few hours a night. It did improve snoring, daytime sleepiness, mood and quality of life (McEvoy et al., NEJM, 2016).

So the strongest reason to get tested is how you feel and function: better sleep, more energy, steadier mood and often easier blood pressure control. For people recovering from a heart attack or stroke, those gains make every other part of recovery, from exercise to medication routines, easier to sustain.

治疗能做什么，不能做什么： 阻塞性睡眠呼吸暂停的主要治疗是 CPAP（持续正压通气），用温和气压保持气道通畅；替代方案包括口腔矫治器、体位治疗以及相关情况下的减重。证据需要如实说明：SAVE 试验纳入 2,717 名有心血管病和睡眠呼吸暂停的人，CPAP 总体上没有减少心梗、卒中或心血管死亡（不过很多参与者每晚只用几小时），但确实改善了打鼾、白天困倦、情绪和生活质量（NEJM 2016）。所以检测最有力的理由是你的感受和功能：睡得更好、精力更足、情绪更稳，血压也往往更好控制。对心梗或卒中康复者来说，这些改善让运动、服药等康复的其他部分更容易坚持。

How Healos™ supports recovery

Healos™ plans don't diagnose or treat sleep apnoea. They track it as part of the bigger picture. The 91-Day Protocol moves through Clear, Replenish and Repair, providing complementary cellular nutrition and lifestyle support, with check-ins at days 30, 60 and 91 that include sleep and daytime energy, so patterns that suggest sleep apnoea are visible and can be raised with your doctor. Sovereign Monthly · Recovery offers the same support month to month.

Healos™ 如何支持康复： Healos™ 方案不诊断或治疗睡眠呼吸暂停，而是把它作为整体的一部分追踪：91 天方案依次经过减负、补给、修复，提供辅助的细胞级营养与生活方式支持，并在第 30、60、91 天评估睡眠和白天精力，让提示睡眠呼吸暂停的模式变得可见，以便向医生提出。Sovereign Monthly · Recovery 按月提供同样的支持。

The bottom line

After a heart attack or stroke, sleep apnoea is common, often missed and easy to screen for. If you snore, stop breathing at night, wake unrefreshed or feel sleepy all day, take the STOP-Bang checklist to your doctor and ask about a sleep test. Treatment may not be a cure for heart disease, but better sleep makes recovery much easier to live.

结论： 心梗或卒中后，睡眠呼吸暂停常见、常被漏诊，而且容易筛查。如果你打鼾、夜里呼吸暂停、醒来不解乏或整天犯困，把 STOP-Bang 清单带给医生，询问睡眠检测。治疗未必能「治好」心脏病，但更好的睡眠会让康复过得容易得多。

Frequently asked questions

Is sleep apnoea common after a stroke? Yes. In a meta-analysis, about 72% of stroke and TIA patients had some degree of sleep-disordered breathing and about 38% had moderate or worse sleep apnoea.

Should I be tested for sleep apnoea after a heart attack? If you snore, have observed breathing pauses, wake unrefreshed or feel sleepy during the day, ask your doctor. A STOP-Bang score of three or more is a common reason to consider testing, often with a home sleep test.

Does CPAP lower the risk of another heart attack or stroke? Large trials such as SAVE did not show a reduction in cardiovascular events overall, but CPAP improved snoring, daytime sleepiness, mood and quality of life, which helps the rest of recovery.

What are the signs of sleep apnoea? Loud snoring, observed pauses in breathing or gasping, daytime sleepiness, morning headaches, waking to urinate at night and high blood pressure are common signs.
