At present, more than one third of adults in the world suffer from hypertension, which deserves great attention. This is the announcement of the 64th World Health Day on April 7 this year. The prevalence of hypertension in China has two distinct characteristics: from the south to the north, the prevalence of hypertension is increasing; the prevalence of hypertension among different nationalities is also different. The prevalence of hypertension is higher among the nationalities living in the north or plateau areas, while the prevalence of hypertension among the nationalities living in the South or non-plateau areas is lower. Hypertension is the most common chronic disease and the most important risk factor of cardiovascular and cerebrovascular diseases. Stroke, myocardial infarction, heart failure and chronic kidney disease are the main complications. Practice at home and abroad has proved that hypertension can prevent and control diseases, reduce the blood pressure level of hypertension patients, significantly reduce stroke and heart disease events, significantly improve the quality of life of patients, effectively reduce the burden of disease. The risk of hypertension is related to the blood pressure level of patients, but also depends on other cardiovascular risk factors, target organ damage and other complications.
