The weather is too hot, chest tightness and shortness of breath. What is the reason? What should we do?

Chest tightness is a symptom of subjective dyspnea. Chest tightness caused by organic reasons: 1. Cardiogenic chest tightness-manifested as fatigue, chest tightness after dyspnea, or paroxysmal dyspnea at night, patients can hold back sleep, which is seen in heart patients 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.
