The diseases treated include angina pectoris, hypertension, sudden death, arrhythmia, heart failure, myocarditis, myocardial infarction and other cardiovascular diseases. Most cardiovascular and cerebrovascular diseases are mainly caused by abnormal metabolism of smooth muscle cells in the blood vessel wall. Vascular tissue and other tissues of the human body complete the process of metabolism within a certain period, but because new cells and tissues cannot be formed normally, There are "defects" in the blood vessel wall itself, so it is easy to produce inflammation and the blood vessels are not constricted smoothly, just like a tattered old pipe, which may be blocked or ruptured at any time. The neurology department closely related to the cardiology department mainly treats cerebrovascular diseases such as cerebral infarction and cerebral hemorrhage, migraine, brain inflammatory diseases such as encephalitis and meningitis, myelitis, epilepsy, dementia, metabolic diseases and genetic predisposition diseases, Trigeminal neuralgia, sciatic neuropathy, peripheral neuropathy and myasthenia gravis. Blood vessels are an important channel for blood circulation, and at the same time, they are also controlled by the nervous system, so the abnormality of the nervous system will also lead to blood supply disorders.

Disorders of cardiovascular and cerebrovascular and blood supply can easily lead to sudden cerebral stroke in patients, which in turn leads to decreased motor function. For patients with decreased motor function, if they do not exercise regularly, other more serious complications will be caused.
