Girls can not breathe chest tightness according to the pattern of attacks and severity, divided into functional and organic, organic diseases are mainly related to cardiopulmonary function is impaired, acute attacks of severe chest tightness need immediate medical attention, to rule out the possibility of life-threatening causes. Cardiac causes: the more common is coronary heart disease. Coronary heart disease is more common in people over 40 years of age, and the risk of coronary heart disease is elevated in postmenopausal women. The sudden onset of unexplained chest tightness and breath-holding may be associated with the onset of an acute myocardial infarction, if previously built. Another more common cause is viral myocarditis, in which cardiac function is impaired due to viral invasion of the myocardium. Cardiac problems can be definitively ruled out by cardiac enzymes, troponin, electrocardiogram, echocardiogram, coronary CT, cardiac MRI or coronary angiography. Lung causes: Lung infections, spontaneous pneumothorax, and lung cancer are more common. Lung infections such as lobar pneumonia will lead to solid changes in the lungs; spontaneous pneumothorax will cause the lungs to be squeezed and shrunken due to the disappearance of negative pressure in the chest cavity; bronchial compression caused by lung tumors or pleural effusion will cause impaired air exchange function of the lungs. Chest X-ray, lung CT, bronchoscopy and other examinations can be used to clearly investigate whether there is lung infection or tumor. Cardiac neurosis should be considered if no organic lesion can be detected after cardiopulmonary function tests. Cardiac neurosis is most common in women between the ages of 20 and 40, especially in menopausal women. There is no evidence of organic heart disease pathologically. Symptoms are varied, with typical symptoms much like those of an acute heart attack, including chest tightness, panic, breathlessness, and tightness and tightness in the precordial area. Further diagnosis and treatment can be made at the Cardiology and Physical Medicine Clinic.
