With the improvement of living standard, the acceleration of work pace, unhealthy eating habits and the reduction of human activities, a large number of patients with hypertension, hyperglycemia and hyperlipidemia are created, which seriously affect people’s physical and mental health. Hypertension, hyperglycemia and hyperlipidemia often work together and interact with each other, and are important causes and main risk factors of many cardiovascular and cerebrovascular diseases, often affecting the structure and function of important organs such as heart, brain and kidney, eventually leading to the failure of these organs and being the main cause of death from cardiovascular and cerebrovascular diseases. The ideal blood pressure value of normal adults should be <120/80mmHg, blood pressure value <130/85mmHg is normal blood pressure; blood pressure value between 130-140/85-90mmHg is critical, is a normal high value; blood pressure value ≥140/90mmHg is hypertension. Those with only one elevated blood pressure cannot be diagnosed as hypertensive yet, and need to be followed up and monitored and blood pressure measured frequently. The normal value of blood sugar is: fasting 3.9-5.6 mmol/L, postprandial ≤7.8 mmol/L, based on venous plasma, the end-of-finger glucose meter test can be used as a reference, but not as a basis for diagnosis, the night before to the morning of the blood sugar test at least 8 hours of fasting. If the symptoms of "three more and one less" are obvious and the fasting blood glucose is ≥7.0mmol/L or the postprandial blood glucose is ≥11.1mmol/L, the diagnosis of diabetes can be made; if there are no obvious symptoms of "three more and one less", the above blood glucose test should be repeated on another day to If the fasting blood glucose is between 5.6-7.0mmol/L or the postprandial blood glucose is between 7.8-11.1mmol/L, it is called impaired glucose regulation, and these people belong to the high-risk group of diabetes and can easily develop into diabetes. The appropriate range of blood lipids is: total cholesterol <5.18mmol/L, triglycerides <1.70mmol/L, LDL cholesterol <3.37mmol/L, HDL cholesterol ≥1.04mmol/L. If total cholesterol ≥6.22mmol/L, triglycerides ≥2.26mmol/L, LDL cholesterol ≥4.14 mmol/L, HDL cholesterol <1.04mmol/L, then the lipid abnormalities are obvious and predispose to atherosclerotic diseases. Those whose lipids are between the appropriate range and obvious abnormalities are borderline elevated, and these people are likely to become the back-up members of cardiovascular and cerebrovascular diseases in the future. Some people sometimes feel fatigue, dizziness, memory loss, poor sleep, eye fatigue, blurred vision, numbness of hands and feet and other mild discomforts, and the symptoms disappear after rest. Most people find out through physical examination, laboratory tests or symptoms related to heart, brain and kidney complications, and some even have serious events and are near death before they are sent to the emergency room. Therefore, early identification of hypertension, hyperglycemia and dyslipidemia, and active intervention and prevention are of great importance to reduce cardiovascular and cerebrovascular events, reduce blindness and serious kidney disease, reduce mortality and improve people's quality of life. To achieve early identification of hypertension, hyperglycemia and dyslipidemia, monitoring is a very important part. In order to detect dyslipidemia in time, fasting lipids should be tested at least once every 5 years for adults over 20 years old; men over 40 years old and postmenopausal women should be checked annually; people with ischemic cardiovascular and cerebrovascular diseases and their high-risk groups should be measured every 3-6 months; when dyslipidemia is first detected, it should be rechecked in 2-4 weeks; patients who are hospitalized for ischemic cardiovascular and cerebrovascular diseases should be tested upon admission or within 24 hours. Patients hospitalized for ischemic cardiovascular and cerebrovascular diseases should have their lipids measured upon admission or within 24 hours. Lipid testing is done through venous serum testing, and the patient should fast for at least 12 hours and maintain a general diet and weight stability for at least 2 weeks prior to blood collection. With the popularization of electronic blood pressure and finger-end glucose meters, blood pressure and glucose monitoring can be performed at any time by oneself, which is more flexible in terms of time and much more convenient than blood lipid testing. Because of the obvious fluctuation of blood pressure, it is necessary to take the average of three readings when self-monitoring blood pressure; if blood pressure rises for the first time, it is necessary to take repeated measurements on different days to determine whether the rise in blood pressure is persistent. As a family self-monitoring blood pressure, generally use the upper arm type fully automatic electronic sphygmomanometer, after strenuous exercise and labor should not be tested immediately, before testing need to sit quietly for a moment, do not hold your breath, so that the mind calm down, take a sitting position, take off one side of the top sleeve, do not roll up the tight sleeve, arm flat, palm up, upper arm and heart at the same level, muscle relaxation; if the lying position, also make the upper arm and For hemiplegic patients, the measurement should be made on the healthy side of the arm; the measurement can be made several times a day, and if you want to observe the fluctuation of blood pressure every day, you should try to set the time, location, position and blood pressure monitor to achieve the accuracy of monitoring and facilitate the adjustment of drug dosage, consolidation and evaluation of drug efficacy. Blood glucose monitoring is helpful to grasp the changes of one's own blood glucose, and can help patients to timely find out the problems that occur during diet, exercise and medication treatment, so that doctors can easily refer to them and timely adjust the treatment plan and improve the treatment status. For those who have just been diagnosed as diabetic and those who have poor or fluctuating blood sugar control with subcutaneous insulin injection or insulin pump, it is recommended to monitor blood sugar daily; 3-4 days after the medication is just adjusted, blood sugar monitoring is required; if the blood sugar is stable without obvious fluctuation or the blood sugar control is better, blood sugar monitoring can be done for one or two weeks or longer. Generally speaking, patients using oral hypoglycemic drugs need to monitor blood glucose four times a day (including fasting and after three meals); patients receiving insulin therapy or using insulin pump need to monitor blood glucose 4-8 times a day (including blood glucose at 2-3 a.m., fasting, after breakfast, before Chinese meal, after Chinese meal, before dinner, after dinner and before going to bed); patients with suspected hypoglycemia or discomfort, and patients with gestational diabetes need to Promptly test blood glucose. Patients should keep a blood glucose monitoring diary, including: time of blood glucose measurement, blood glucose value, meal time and meal quantity, exercise time and exercise quantity, medication quantity and time, and records of some special events. Therefore, it is especially important to remind that blood glucose monitoring should not only measure fasting blood glucose, but also pay attention to postprandial blood glucose monitoring, and glycated hemoglobin should be tested once every 3-6 months to observe the overall blood glucose control situation in the past 3 months or 6 months.
