What is pain in the upper part of the heart?

Pain in the upper part of the heart may be caused by myocarditis, angina pectoris, acute myocardial infarction and other factors. The relevant explanations are as follows:

1. Myocarditis

myocarditis will cause myocardial cells to be infected by inflammation, leading to local redness, exudation and swelling, affecting myocardial pulsation, resulting in bursts of chest pain, palpitation, fatigue and other symptoms.

2. Angina

pectoris patients due to coronary artery stenosis or blockage, resulting in myocardial ischemia, will cause myocardial spasm, paroxysmal pressure or dull pain behind the sternum.

3. Acute myocardial infarction

patients with myocardial necrosis, necrotic metabolites stimulate myocardial sites, leading to local obvious dysfunction, causing paroxysmal chest pain.
