Chest tightness and shortness of breath is a common symptom of heart disease and is also a subjective feeling. Patients usually feel feelings such as breathlessness and very labored breathing, and in some cases it can even be frightening. However, patients with mild symptoms of chest tightness and shortness of breath are likely to recover naturally within a short period of time, while those with more severe symptoms may feel uncomfortable, as if a heavy weight is being squeezed in the chest area, causing breathing to become difficult. The symptom of chest tightness and shortness of breath can occur in anyone who engages in a lot of exercise, which is caused by excessive myocardial oxygen consumption, and when we look at this problem, we need to pay attention to whether the patient’s physical fitness and age are in line with his/her duration of exercise. Of course, there are many causes of excessive myocardial oxygen consumption or reduced oxygen supply to the coronary arteries, and we need to treat the symptoms in order to restore health more quickly. The causes of chest tightness and shortness of breath are divided into two cases, one is functional chest tightness and shortness of breath, and the other is caused by pathological factors Functional chest tightness: that is, psychological factors affecting the room in the closed doors and windows, the air does not circulate for a longer period of time, or encountered some unpleasant things, or even with other people in verbal disputes, disputes, or in the climate of the air pressure is low, often resulting in chest tightness, fatigue feeling. Pathological factors: I. Respiratory tract obstruction: tracheobronchial long tumors, tracheal stenosis, this kind of disease will make the patient feel chest tightness, gasping for air. Lung diseases: emphysema, bronchitis, asthma, pulmonary atelectasis, pulmonary infarction, pneumothorax and so on. Third, heart disease: certain congenital heart disease rheumatic heart valve disease, cardiac tumors and so on. Fourth, cervical and thoracic spine lesions: cervical and thoracic spine degenerative lesions (such as: disc protrusion, ligamentum flavum hypertrophy, lumbar spine instability, cervical spondylosis, etc.) will stimulate the compression of peripheral nerves of the vertebrae to make the nerves abnormally excited, resulting in vasospasm and contraction of vascular spasms, so that myocardial ischemia and ischemia, which will also appear in the chest tightness and shortness of breath symptoms. Fifth, transient chest tightness and shortness of breath: the reason is that the inspiratory center appears to inhibit the phenomenon. Under normal circumstances, the human body through the lungs evenly a breath to complete the exchange of oxygen and carbon dioxide, but sometimes due to the accumulation of carbon dioxide in the lungs, stimulate the excitement of the inhalation center, so that inhalation intensified, resulting in a short period of deep inhalation, followed by a breath of phenomenon, which is a normal physiological phenomenon. Understanding the “chest tightness and shortness of breath is how”, the patient should be how to treat it? 1, if you are in a bad mood or the environment causes chest tightness and shortness of breath, then you must relax your mind, maintain a good mood, calm and collected. Pay attention to regular life, work and rest, and appropriate physical exercise, shortness of breath will disappear. 2, if it is a pathological chest tightness and shortness of breath, then we must find the cause of the disease, that is, the underlying foci and foci, for the treatment of the cause, heart failure patients to restore the normal function of the heart, coronary heart disease patients to restore blood circulation, cervical and thoracic spine patients need to eliminate the foci, regulation of the disorder of the excited nerves. Warm tips: patients who often have chest tightness and shortness of breath must go to the hospital in time. In the course of treatment, we should carefully identify, distinguish between functional and pathological. If it is a pathologic chest tightness and shortness of breath, we should actively search for the cause of the disease, and carry out the necessary treatment to completely eliminate the symptoms.
