Gastroscopy can be done during the stabilization period after stenting for heart attack, but ECG, blood pressure measurement and other tests need to be perfected before gastroscopy. Gastroscopy is mainly applicable to patients who need to clarify the cause of digestive tract diseases, but because it is invasive, some patients are not allowed to do gastroscopy, such as the attack period of serious heart disease, the attack period of serious lung disease, the gastrointestinal tract hemorrhage, suffering from mental illnesses that can not be cooperated with, and acute pharyngeal disease, and so on. Patients after stenting for heart attack, taking medicines regularly according to the doctor’s prescription, are allowed to have gastroscopy if their heart disease is in a stable period and their electrocardiogram and blood pressure are normal before gastroscopy. If there is discomfort in the precordial area or symptoms in the digestive tract, it is recommended to consult a doctor in time to avoid delaying the condition.
