The difference between the symptoms of pneumonia and myocarditis lies mainly in the fact that the clinical manifestations of the former are mainly in the respiratory system (e.g. coughing, coughing up sputum, dyspnea, etc.), while the latter is mostly characterized by abnormalities in cardiac function (e.g. palpitations, arrhythmias, etc.).
Most pneumonias have a rapid onset, and due to impaired lung function, they often manifest as coughing, coughing up (pus, blood) sputum, accompanied by high fever, chills, generalized muscle aches and pains, and in severe cases, respiratory distress and respiratory failure may occur.
Myocarditis is mostly caused by viral infections, such as Coxsackie virus, etc. It starts slowly and can involve the myocardium, interstitium, endocardium and pericardium. When myocarditis is severe, it may lead to the decline of cardiac function, which may be manifested as fever, sore throat, cough, diarrhea and other symptoms in the early stage, followed by cardiac arrhythmia, bradycardia, atrioventricular block and other triggered by black haze, fainting; severe myocarditis can be seen in cardiogenic shock.
Patients with symptoms of pneumonia or myocarditis are advised to go to a specialized hospital to clarify the cause of the disease and then under the guidance of the doctor for further examination and treatment.
