If the ST segment elevation is caused by coronary artery spasm, it may be cured by itself. If it is caused by myocardial infarction, hypertrophic cardiomyopathy, etc., it usually cannot be cured by itself. Whether ST segment elevation can be self-healed needs to be judged according to the cause of the disease. If ST segment elevation is caused by coronary artery spasm, it may be self-healed after the coronary artery spasm is relieved, and then the ST segment will return to the normal position after the electrocardiogram is performed. If ST segment elevation is caused by myocardial infarction, hypertrophic cardiomyopathy, acute viral myocarditis, acute pericarditis and other diseases, it usually cannot be cured. It is recommended that patients with ST segment elevation need to consult a doctor in time, and for exclusion of coronary artery spasm resulting in ST segment elevation, appropriate measures need to be selected under the guidance of the doctor for treatment. In addition, patients should ensure enough rest, avoid overwork, usually also keep a relaxed mood, avoid emotional excitement. Diet needs to eat green vegetables, bananas, milk, fish and other foods rich in vitamins and proteins. It is recommended that patients seek timely medical treatment and standardize the treatment under the guidance of doctors.
