The first thing to consider is heart disease, as heart fever can occur with varying degrees of myocardial ischemia. Typical angina pectoris may manifest itself as suffocation and pain in the precordial region, in the form of stabbing pain or colic, while some patients with atypical angina pectoris may also have a feeling of heart heat. Therefore, if heart disease is suspected, cardiovascular imaging or coronary artery CT should be done to determine whether there is stenosis, as well as the location and degree of stenosis, so as to determine whether the feeling of heartburn is related to myocardial ischemia. In addition, the feeling of heart heat should also be ruled out as a stomach disorder because the stomach is under the saber process and stomach lesions are easily confused with heart disease. If you suspect stomach disorders, you need to do imaging examination of the stomach, the most intuitive is gastroscopy, to determine whether there is gastritis, gastric ulcer, gastric erosion and other diseases, different degrees of acid reflux, heartburn feeling can also be manifested as heart heat.
