What diseases are easily confused with coronary artery disease? Myocarditis: Myocarditis refers to a limited or diffuse acute, subacute or chronic inflammatory lesion in the myocardium. Severe arrhythmias, cardiac insufficiency and even sudden death can occur in severe cases. The patient may have fever, fatigue, excessive sweating, panic, shortness of breath, and dull pain in the precordial region. Treatment includes resting, improving myocardial nutrition, controlling cardiac insufficiency and correcting arrhythmia, preventing secondary infection, etc. 2, pericarditis: pericarditis can be divided into acute pericarditis, chronic pericarditis, constrictive pericarditis, patients can have fever, night sweats, cough, sore throat, or vomiting, diarrhea, pericardium soon exuded a large amount of fluid can occur when the symptoms of acute cardiac tamponade, patients with chest pain, dyspnea, cyanosis, pallor, and even shock, but also ascites, hepatomegaly and other symptoms. Pleurisy: pleurisy, also known as “costochondritis”, is an inflammation of the pleura, after the inflammation subsides, the pleura can return to normal, or two layers of pleural adhesion, caused by a variety of etiologies, such as infection, malignant tumors, connective tissue disease, pulmonary embolism, etc. Tuberculous pleurisy is the most common one, dry pleurisy, pleural surface with a small amount of fiber exudate, manifested as severe chest pain, like a pinprick, examination can be found In exudative pleurisy; with the increase of exudate in the pleural cavity, chest pain decreases or disappears, the patient often has cough and may have difficulty in breathing, in addition, there are often fever, emaciation, fatigue, loss of appetite and other systemic symptoms, examination can reveal the heart and lung compression, in the case of large amounts of pleural fluid, can be detected by chest examination and X-ray examination, the treatment of tuberculous pleurisy mainly includes tuberculosis drug therapy The treatment of tuberculous pleurisy mainly includes tuberculosis medication; accelerating the absorption of pleural fluid, pumping treatment if necessary; preventing and reducing pleural thickening and adhesions, choosing adrenocorticotropic hormone, etc. Pleurisy is an inflammation of the pleural wall and dirty layer caused by various reasons, mostly secondary to lesions in the lungs and chest, but also as a local manifestation of systemic diseases. For hyperthyroid heart, rheumatic heart disease, and coronary heart disease there is a special measurement differential diagnosis: hyperthyroid heart disease (referred to as hyperthyroid heart), rheumatic heart disease (referred to as rheumatic heart disease), and coronary arteriosclerotic heart disease (referred to as coronary heart disease) are three distinct cardiac lesions, but in a certain period of the disease, their manifestations are quite similar, thus prone to misdiagnosis and mistreatment. Clinical application method: The various symptoms and signs (positive or negative) of patients are recorded one by one according to the corresponding diagnostic indices in the table, and then added together. For example, if the index of hyperthyroid heart is larger, the diagnosis is hyperthyroid heart disease; if the index of coronary heart disease is larger, the diagnosis is coronary heart disease; if the index of wind heart disease is larger, the diagnosis is wind heart disease.
