Cardiovascular and cerebrovascular diseases are a general term for cardiovascular and cerebrovascular diseases. They generally refer to ischemic or hemorrhagic diseases of the heart, brain and body tissues caused by hyperlipidemia, blood viscosity, atherosclerosis, hypertension, etc. Cardiovascular and cerebrovascular diseases are common diseases that seriously threaten the health of humans, especially middle-aged and elderly people over 50 years old. They are characterized by high prevalence, high disability and high mortality. Even with the most advanced and complete treatments, more than 50% of survivors of cerebrovascular accidents are still unable to take care of themselves. As many as 15 million people die from cardiovascular and cerebrovascular diseases in the world every year, ranking first among all causes of death. Common cardiovascular and cerebrovascular diseases mainly include hypertension, coronary heart disease and stroke. Coronary heart disease can cause angina pectoris, myocardial infarction and even sudden death, while stroke can be ischemic cerebral infarction or hemorrhagic cerebral hemorrhage. At present, the incidence of these cardiovascular and cerebrovascular diseases is showing a trend of younger people in our country, which means that the age of getting cardiovascular and cerebrovascular diseases is getting earlier and earlier. The author has encountered a considerable number of cardiovascular and cerebrovascular patients in the age group of 30 to 40 years old, among whom the youngest patient with coronary heart disease is 29 years old. At the same time, survey data shows that my country is becoming a country with high blood pressure and coronary heart disease. Therefore, it can be said that cardiovascular and cerebrovascular diseases have become a social problem in our country, not just a health problem. Understand and pay attention to cardiovascular and cerebrovascular diseases. Only by understanding them can we understand how to prevent them, how to avoid detection, how to treat them and how to treat them. Those who have not suffered from it can take precautions before it happens; those who have already experienced it can handle it appropriately to stay safe.
