Reflux esophagitis does not usually cause heart attack. Reflux esophagitis can be caused by reflux irritation of the esophagus causing severe stabbing pain behind the sternum, which can radiate to the precordial area, sometimes resembling angina pectoris or myocardial infarction, so patients with reflux esophagitis may mistakenly think that myocardial infarction has occurred. Myocardial infarction is often caused by coronary artery disease and myocardial lesions, and its onset is related to heredity, hyperlipidemia, diabetes mellitus, coronary atherosclerosis, emotional excitement, etc., which has little to do with reflux esophagitis. Patients with myocardial infarction tend to have more severe symptoms of chest pain, and patients are often irritable, sweaty, fearful, and complicated by arrhythmia, hypotension and shock. Therefore, patients with reflux esophagitis should go to the hospital in a timely manner to clarify the cause of chest pain and receive early treatment to avoid the development of the disease.
