If a male patient has pain in the middle of the chest, he can be registered in the emergency department, or in the cardiology, circulatory medicine, thoracic surgery or in the general medicine department. If a male patient has high risk chest pain with unstable vital signs, such as unstable heart rate, blood pressure, pulse, etc., the patient must go to the emergency department first and then be transferred to the appropriate department for further treatment after the vital signs are stabilized. For male patients with a history of coronary heart disease and pain in the middle of the chest, they can go to the cardiology department for consultation. Male patients with a history of traumatic injuries, fractures or contusions of the sternum or ribs may be referred to the Department of Thoracic Surgery. For non-tertiary care hospitals where the subspecialties are not very clear and detailed, you can also register at the Department of Allopathic Medicine.
