The weather is bad, how is chest tightness and shortness of breath?

Chest tightness is a symptom of subjective dyspnea.

Chest tightness caused by organic reasons:

First, cardiogenic chest tightness-manifested as chest tightness after fatigue, dyspnea, or paroxysmal dyspnea at night, patients can hold back sleep, which is seen in patients with heart disease with pulmonary congestion and cardiac insufficiency. Chest tightness can also be the manifestation of angina pectoris during myocardial ischemia of coronary heart disease.

Second, pulmonary chest tightness-seen in bronchial asthma, pleural effusion, spontaneous pneumothorax, pulmonary fibrosis and so on.

Chest tightness caused by nervous function-common in cardiovascular dysfunction. Patients feel chest tightness, shortness of breath, subjective lack of air, poor breathing, often sigh-like breathing, and feel comfortable after breathing; It is often accompanied by palpitations, tingling in the precordial area, and nervous system symptoms such as fatigue, dizziness, confusion, anxiety, hyperhidrosis and insomnia. The disease is sometimes similar to coronary heart disease and angina pectoris, but no organic lesions were found in ECG and B-ultrasound.

In addition, organic chest tightness mostly occurs after exercise or fatigue, and functional chest tightness mostly occurs at rest; After sitting up, the organic chest tightness can be obviously improved, while the functional chest tightness often does not change because of the change of posture.

Chest radiograph, electrocardiogram and echocardiography can be done when there are symptoms of chest tightness. If no abnormalities are found in the examination, most of them are neurological symptoms.

Treatment:

1 psychotherapy: adjust the mentality, relax the spirit, eliminate worries, cultivate an optimistic and open-minded personality and maintain a good mood. Good mood is conducive to the coordination and unity of nervous system, organs and systems, so that the body's physiological metabolism is in the best state, thus enhancing the vitality of brain cells and improving nerve function in a feedback way.

Physical exercise: Physical exercise can regulate and improve the process of brain excitement and inhibition, and regulate brain function. In addition, exercise can obviously change people's mood, persist in long-term exercise, enhance physical fitness, improve cardiovascular function, enhance the regulation function of autonomic nerve, and restore autonomic nerve function.

3 drug therapy:

Patients with beta-receptor allergic symptoms such as palpitation, chest tightness, sweating easily and dyspnea can take diazepam 2.5mg and propranolol 10mg (or propranolol 12 .5~25mg 1~2 times a day) orally.
