The pain in the chest every afternoon should be given great attention and should be considered as a heart disease, and the patient should go to the hospital for relevant examination and diagnosis in time. In the hospital for electrocardiogram examination to determine whether there is myocardial ischemia, if there is such a situation, it is best to carry out cardiac CT examination, through the cardiac CT imaging examination will be able to clearly determine whether there is a blockage of the heart vessels, or the severity of the blockage. When the blockage of heart blood vessels reaches 75% or more, heart stent surgery is generally required to prevent life-threatening attacks of heart attack later. If the patient does not have ischemia, it is generally considered to be due to long periods of non-rest, such as not taking a nap or long hours of labor or hard work, which can cause the patient to have a lack of heart energy and chest tightness. Because prolonged overwork will make the patient’s sympathetic nerves appear abnormally excited, which will seriously damage the heart muscle leading to the phenomenon of chest tightness. In addition, in addition to heart disease, lung disease, thoracic and rib diseases are not ruled out every afternoon. Patients can undergo relevant examination in the hospital to clarify the diagnosis for symptomatic treatment.
