The theme of this year’s World Hypertension Day was originally set to be “Take your own blood pressure at home”, but was later changed to “Measure your blood pressure in the community or at home” at the suggestion of Professor Lixson Liu, President of the World Hypertension League. In 2007, a working group composed of members of nine international health organizations proposed the slogan “Five Actions for the World to Take”, which included screening of hypertensive patients, risk stratification and prediction, building a good The five areas of the initiative include screening, risk stratification and prediction, establishing a good doctor-patient relationship, treatment and compliance, and creating a supportive environment, and these important programs need to be implemented in the community. Self-measurement of blood pressure by patients is still controversial among professionals, mainly because there are some potential drawbacks and side effects of such measurements, such as some patients adding medication or changing medical advice based on the results of self-measurement, and also because multiple blood pressure measurements a day may lead to high levels of mental stress, especially for patients with neurological deficits. Therefore, it is more appropriate to routinely measure blood pressure once a year or once every two years for people with normal blood pressure, and once a day for people with high blood pressure and those who are already on medication, to provide a reference for the next visit to the doctor. Mercury sphygmomanometers will be phased out! Mercury sphygmomanometers are no longer used clinically in some Nordic countries because of the problem of environmental pollution. Automatic and semi-automatic electronic sphygmomanometers are more appropriate for use in the community and at home, and semi-automatic sphygmomanometers are more energy-efficient. There are hundreds of electronic sphygmomanometers on the market today, and their accuracy is still to be identified. The World Health Organization (WHO) and the International Society of Hypertension (ISH) have developed guidelines for sphygmomanometers, and China is also implementing these guidelines. Measuring blood pressure in the community and at home requires, first, that the sphygmomanometer be accurate and, second, that the patient be taught the correct way to use it. Professor Lixiang Liu, President of the World Hypertension League, pointed out that the purpose of self-measurement at home is to urge the public, especially hypertensive patients, to pay attention to self-measurement of blood pressure, to keep abreast of their blood pressure, and to improve compliance with treatment for better control of hypertension. Self-measurement of blood pressure has positive significance in improving the initiative of treatment and control of hypertension, and is of great value in differential diagnosis of hypertension, assessment of therapeutic efficacy and prediction of the risk of cardiovascular disease. Therefore, it is important for hypertensive patients to pay attention to their own blood pressure, to actively participate in their own treatment, and to discuss with their doctors the appropriate treatment plan for them, rather than not caring about their home blood pressure situation and only giving this task to their doctors who only see them once every half month or month. Therefore, I encourage patients to take their own blood pressure and record it so that they can better adjust their medication and obtain a satisfactory treatment plan and outcome!
