Generally speaking, the common clinical causes of chest pulling pain can be seen in the following conditions. One, patients with coronary atherosclerotic heart disease, if subjected to further exertion and stimulation, the heart will have continuous contraction, resulting in myocardial ischemia, hypoxia, and chest pain. In this case, patients need to take nitroglycerin orally as soon as possible to dilate the heart vessels, and improve coronary angiography to clarify the severity of heart vessel stenosis. If necessary, cardiovascular stents should be implanted to expand the heart vessels and restore blood flow, so as to reduce the chest pain. Secondly, in patients with malignant breast tumor, once the tumor cells invade the chest wall muscle layer, it can cause pulling pain in the chest, patients can improve the magnetic resonance imaging or mammography examination of the breast. After confirming the nature of the lesion, breast malignant tumor resection and lymph node dissection should be performed as soon as possible. After the surgery, local radiotherapy and systemic chemotherapy should be combined to kill the cancer cells in the body as much as possible to relieve the chest pain.
