If a patient wakes up with pain in the heart in the morning: First, cardiogenic diseases should be considered, such as coronary artery disease unstable angina, acute myocarditis, pericarditis, hypertrophic obstructive cardiomyopathy, valvular disease of the heart or aortic coarctation, which can lead to morning precordial pain, accompanied by chest tightness, shortness of breath and precordial discomfort, usually directly related to ischemic stenosis spasm of the coronary arteries. Second, for patients with significant previous vegetative nerve disorders, they may also wake up in the morning with heart pain in the presence of cardiac neurosis. Third, for patients with a clear history of previous gastrointestinal diseases, if they have gastroduodenal ulcer or reflux esophagitis, they will also have acid reflux and heartburn in the gastrointestinal tract in the morning, which will reflexively lead to anterior heart pain in the morning. Fourth, if there is a significant infection in the respiratory system, such as a large lung infection, pleural effusion, or pleurisy, this clinical manifestation will also occur.
