Sleep apnea is fairly common in people with heart failure. Sleep apnea means you stop breathing for 10 seconds or longer during sleep. Types of sleep apnea include central sleep apnea (CSA) and obstructive sleep apnea (OSA). CSA is caused by a problem with how the brain signals the breathing muscles. OSA happens when your airway gets blocked while you sleep. Some people have both types.
When you stop breathing, the amount of oxygen in your blood drops, so your heart has to work harder to get enough oxygen to your body's tissues. Your heart failure symptoms may get worse. Sleep apnea may also cause you to snore loudly and not sleep well, so you wake up feeling tired.
Getting treatment for sleep apnea may help you sleep and feel better.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse advice line (811 in most provinces and territories) if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
Watch closely for changes in your health, and be sure to contact your doctor or nurse advice line if you have any problems.
