Hypertension is the main cause of cardiovascular diseases, the occurrence of stroke, coronary heart disease and other diseases are closely related to hypertension, these diseases cause high rates of death and disability, and should cause people to pay attention to, and take reasonable prevention methods to actively prevent hypertension. The relationship between hypertension and cardiovascular diseases Studies have found that hypertension is the most important risk factor for early onset cardiovascular diseases, resulting in about 54% of strokes and 47% of ischemic heart diseases worldwide, such as stroke, coronary heart disease, heart failure, etc., are its common complications, and patients have a high incidence and disability rate. Relevant data show that the current mortality rate of cardiovascular diseases in China accounts for 41% of the total mortality rate, and the number of deaths reaches 3.5 million each year, of which 70% of strokes and 50% of myocardial infarctions are related to hypertension. Prevention of hypertension combined with cardiovascular and cerebrovascular diseases In view of the great danger of hypertension combined with cardiovascular and cerebrovascular diseases to human body, daily can be prevented by strengthening self-care and insisting on standardized treatment, which can be divided into primary prevention and secondary prevention of cardiovascular and cerebrovascular diseases. 1, primary prevention The primary prevention of hypertension combined with cardiovascular and cerebrovascular disease is an intervention for people who have not yet developed hypertension combined with cardiovascular and cerebrovascular disease. It usually refers to changing unhealthy living habits, such as quitting smoking and limiting alcohol, reducing sodium intake, strengthening physical exercise and weight control, and eating a reasonable diet. At the same time, it is combined with medication to control blood pressure, blood lipid and blood sugar abnormalities, etc. 2.Secondary prevention Secondary prevention is to prevent the recurrence and aggravation of myocardial infarction, stroke and other cardiovascular and cerebrovascular diseases by taking preventive and curative measures for patients who have already had myocardial infarction and stroke. The measures of secondary prevention not only include all the measures of primary prevention, but also actively treat the cardiovascular and cerebrovascular diseases that have already occurred, and patients need to be followed up regularly and use anti-atherosclerotic drugs under the guidance of doctors, with the aim of reducing the related disability and death. To sum up, hypertension is a common and frequent disease, with serious hazards and a rising trend. Therefore, high-risk groups should pay attention to lifestyle modifications, standardize treatment, and bring blood pressure control up to standard in order to reduce the incidence of combined cardiovascular and cerebrovascular diseases in patients, thereby improving the quality of life.
