Chest pain is not necessarily a new type of pneumonia. Diseases of chest pain include heart disease, lung disease, pleurisy and gastrointestinal disease. If a young person was previously healthy and suddenly develops chest pain, consider pleural and lung diseases, such as pneumothorax, pleural effusion, pneumonia, etc., and improve blood routine and imaging of chest and lung to clarify the diagnosis. In case of chest pain in the elderly, be alert to critical diseases such as angina pectoris, myocardial infarction, thoracic aortic coarctation, etc. Perform electrocardiogram as soon as possible, improve the determination of cardiac function and myocardial enzyme profile, and perform chest angiography if necessary for the best time of rescue. If the patient has chest pain with a burning sensation, pay attention to the presence of reflux esophagitis, which can be relieved by giving treatment such as omeprazole. Novel pneumonia can cause chest pain and a positive nucleic acid test is required to confirm the diagnosis of novel pneumonia.
