The common reasons for patients sleeping with chest pain are mainly the following: a. Improper posture of patients sleeping at night can cause continuous pressure at the chest, causing spasmodic pain in the local muscles. At this time, patients can improve the local blood circulation through appropriate massage at the chest muscles, and after sufficient rest, the symptoms of chest muscle pain can be relieved more quickly. Second, patients with coronary atherosclerotic heart disease, after sleeping up appropriate activities aggravate the oxygen consumption of the heart, causing irregular spasmodic contraction of the heart, which can cause heart ischemia, hypoxia, chest pain symptoms. At this time, patients can take oral nitroglycerin tablets to improve the symptoms of cardiac ischemia and hypoxia. If the patient still has pain, it is recommended to go to the hospital as soon as possible to improve the cardiac coronary angiography to clarify the severity of heart stenosis, and if necessary, perform interventional treatment to restore heart blood flow and reduce pain symptoms.
