Does big BP represent hypertension? Hypertension is a clinical syndrome characterized by elevated systolic and/or diastolic blood pressure (systolic blood pressure (> 140 mm Hg) and diastolic blood pressure (> 90 mm Hg) in systemic circulation. It can be accompanied by functional or organic damage of heart, brain and kidney. Hypertension is the most common chronic disease and the most important risk factor for cardiovascular and cerebrovascular diseases. Normal people's blood pressure fluctuates within a certain range with the changes of internal and external environment. In the population as a whole, blood pressure level gradually increases with age, especially systolic blood pressure, but after 50 years of age, diastolic blood pressure shows a downward trend, and pulse pressure also increases. In recent years, people have deepened their understanding of the role of multiple risk factors of cardiovascular disease and the protection of target organs of heart, brain and kidney, and the diagnostic criteria of hypertension have been constantly adjusted. At present, it is considered that patients with the same blood pressure level have different risks of cardiovascular disease. Therefore, the concept of blood pressure stratification has been developed, that is, patients with different risk of cardiovascular disease should have appropriate blood pressure level. Different. Blood pressure value and risk factor assessment are the main basis for diagnosis and formulation of treatment plan for hypertension. Different patients have different goals of hypertension management. On the basis of reference criteria, the most appropriate blood pressure range of the patients is judged according to their specific conditions, and targeted treatment measures are adopted. On the basis of improving lifestyle, 24-hour long-acting antihypertensive drugs are recommended to control blood pressure. In addition to assessing the blood pressure in the clinic, you should also pay attention to the monitoring and management of family blood pressu
