Cerebrovascular diseases include several kinds.

Cardiovascular and cerebrovascular diseases can be divided into cardiovascular and cerebrovascular diseases. Cardiovascular diseases are mainly coronary heart disease, which is caused by coronary atherosclerosis, arterial stenosis or occlusion and insufficient blood supply to myocardium. Clinically, it can be divided into recessive coronary heart disease, angina pectoris, myocardial infarction, myocardial fibrosis and sudden cardiac death. Cerebrovascular disease is a group of diseases with cerebral hemorrhage or ischemic injury as the main clinical manifestation, commonly known as stroke, which is the main disease that causes human death and disability at present. Coronary heart disease: the full name is coronary atherosclerotic heart disease, characterized by coronary atherosclerosis and angina pectoris. When coronary atherosclerosis develops to a certain extent, it will lead to severe stenosis of coronary artery lumen, resulting in myocardial ischemia and hypoxia, which will lead to a series of symptoms. Such as chest tightness, tingling in the heart, angina pectoris and arrhythmia. In severe cases, myocardial infarction will occur, leading to heart failure, sudden death and life-threatening. The main risk factors of coronary heart disease are hyperlipidemia, hypertension, smoking and drinking, diabetes, lack of exercise, irregular diet and obesity. Angina Pectoris: It is the main symptom of coronary heart disease and a group of symptoms caused by acute and temporary myocardial ischemia and hypoxia. The main manifestations are chest compression, suffocation, abdominal distension and severe burning pain. Generally, the pain lasts 15 minutes, and occasionally relieves itself. Pain often radiates to the left shoulder, the anterior and medial side of the left arm, the little finger and the ring finger. Angina pectoris will aggravate the condition of coronary heart disease, causing heart failure and sudden death. Myocardial infarction refers to the occlusion and blood flow interruption of a branch of coronary artery, which leads to continuous ischemia and hypoxia of the myocardium nourished by this branch, and is the primary cause of heart disease death. If the lesion is too large or the rescue measures are not effective, it will lead to serious consequences such as heart rupture, heart failure and sudden death. Timely rescue, after a period of treatment and rest, can get some recovery, but most of them will leave sequelae such as cardiac insufficiency and arrhythmia. Myocardial infarction is a critical symptom of coronary heart disease, which is usually based on frequent and aggravated angina pectoris, and it is also caused by angina pectoris (this situation is the most dangerous and often leads to sudden death due to failure to prevent it). Cerebral infarction: It is due to the atherosclerosis of cerebral vessels, which blocks the cerebral vessels, resulting in insufficient blood supply and oxygen supply to the brain. Common symptoms include dizziness, insomnia, forgetfulness, numbness of limbs, emotional instability, memory disorder, and even brain cell injury or death in severe cases, leading to brain dementia, stroke, and even vegetative state. Cerebral infarction is an early symptom of cerebrovascular disease. Brain dementia: also known as dementia syndrome, it is a chronic mental disorder characterized by slow mental decline, and there are many different brain atrophy. The early manifestations are memory loss, confusion, difficulty in understanding, poor judgment and decreased calculation function, which leads to aphasia. With the development of the disease, mental symptoms can appear, and finally life can't take care of itself at all, becoming a vegetative state. Generally, he died of brain failure or complications 3 ~ 8 years after onset. There are mainly Alzheimer's disease, Alzheimer's disease and arteriosclerosis dementia. Modern medical research shows that brain dementia is mainly due to the disorder of blood microcirculation in patients' brains and excessive free radicals, which act on brain cells for a long time. In China, the prevalence of brain dementia in the elderly over 65 years old is as high as 3.86%, and with the acceleration of the aging process, this number will rise sharply. Cerebral hemorrhage: also known as cerebral hemorrhage and hemorrhagic stroke, it is a common acute hemorrhagic cerebrovascular disease, mainly cerebrovascular atherosclerosis, which narrows and embrittles the local official cavity of cerebral blood vessels and occludes the blood vessels. When the blood spreads here, the impulse generated by the blood flow exerts great pressure on the blood vessel wall, which eventually leads to blood vessel rupture and cerebral hemorrhage. The consequences of cerebral hemorrhage often lead to severe hemiplegia, vegetative state and even death. Therefore, the prevention of cerebral hemorrhage should be put in the first place.
