Hypertension is a common disease, but people often do not know enough about the disease, the following are common misconceptions about hypertension: 1, a little high blood pressure does not matter, no need to make a fuss In fact, a large number of observational studies have confirmed that even a little high blood pressure, the risk of cardiovascular disease will increase significantly, for hypertension, do not take a care attitude, must be taken seriously. 2, a little high systolic blood pressure is not harmful, as long as the diastolic blood pressure is normal on the long-held view that the danger of hypertension mainly lies in the diastolic blood pressure increase should be corrected. Because, the latest clinical research confirms that the danger of increased systolic blood pressure is much greater than the increase in diastolic blood pressure. 3, the increase in blood pressure in the elderly is a physiological phenomenon The increase in blood pressure in the elderly is not a physiological phenomenon, and the diagnostic criteria for hypertension in the elderly are the same as those for young people. The Chinese guidelines for the prevention and treatment of hypertension state that the goal of hypertension in the elderly is systolic blood pressure.
