The causes of chest compression pain after waking up from sleep are particularly varied and relatively complex in clinical practice. In younger patients it may be due to poor rest or pressure on the chest due to incorrect sleep posture during sleep, which can cause pressure pain in the chest area when awake or when waking up. This condition may also be due to compression symptoms caused by body posture, which leads to poor local blood circulation and tends to cause some pain. In addition, elderly people who experience this symptom after waking up from sleep must not be ignored as an emergency, including life-threatening diseases such as coronary syndrome and acute myocardial infarction. Therefore, elderly people with chest compression pain must go to the hospital for detailed examination, including review of cardiac enzymes, electrocardiogram and relevant color ultrasound, to exclude acute diseases, and then carry out systematic and standardized treatment according to the specific cause.
