Chest drawing pain, clinically common causes are mainly the following: a. Patients with severe lung infection need to cough and discharge sputum repeatedly due to the large amount of sputum in the lungs, which will cause drawing pain in the chest. At this time, patients can dilute sputum by nebulized inhalation and strengthen anti-infection treatment intravenously to dissolve sputum to promote faster sputum discharge. After controlling the lung infection, the chest pain can be relieved more quickly. Second, patients with coronary arteriosclerotic heart disease will experience spasmodic contraction of heart vessels under the effect of factors such as overexertion or stimulation, causing radiating pain in the chest. In this case, the patient can improve the coronary angiography examination to clarify the severity of heart vessel stenosis, and if necessary, perform vascular stent implantation to expand heart vessels, improve blood flow and reduce the chest pain.
