Blood pressure 140~100 mainly refers to systolic blood pressure 140mmhg and diastolic blood pressure 100mmhg, which is more serious. Usually, if the blood pressure is measured on three occasions not on the same day under the quiet state of adults, the systolic blood pressure ≥140 and/or diastolic blood pressure ≥90mmhg can be diagnosed as high blood pressure; and the systolic blood pressure of 140mmhg, diastolic blood pressure of 100mmhg has reached the diagnostic standard of second-degree hypertension, which belongs to the more serious situation. Usually, for those with Grade 2 hypertension, a smaller effective therapeutic dose should be used at the beginning of the treatment, and then the dose should be gradually increased; if necessary, the treatment should be combined with another antihypertensive drug, such as enalapril combined with nifedipine, enalapril combined with hydrochlorothiazide, and nifedipine combined with hydrochlorothiazide, so as to control the blood pressure in the ideal range. When abnormal blood pressure occurs, it is recommended to go to the hospital in time for consultation and early standardized treatment, and not blindly use medication on your own.
