A fever and cold can cause haematoma and oedema of the nasal mucosa and respiratory tract, leaving the patient struggling to breathe and feeling short of breath in the chest. If symptoms such as chest pain, palpitations, shortness of breath and dyspnea occur at the same time, it is important to pay attention and be alert to the occurrence of acute myocarditis. It is recommended to visit the hospital promptly and receive early standardized treatment to avoid aggravation of the condition. A combination of examination of chest X-ray, ECG, cardiac ultrasound, cardiac enzymes and BNP is usually performed to clarify the cause.
