The conditions for hypertension to do chronic disease are: 1. First, secondary hypertension should be excluded and primary hypertension should be considered. 2. Blood pressure should be greater than or equal to 160/100mmHg or more. If you want to apply for hypertension chronic disease, you should go to a tertiary care hospital to issue a certificate, complete 24-hour ambulatory blood pressure monitoring in a tertiary care hospital to understand the fluctuation of blood pressure for 24 hours, whether it is arytenoid or non-arytenoid, and the blood pressure should be greater than 160/100mmHg for more than 8 times, or more than 160/100mmHg for 3 consecutive times at different times. if hypertension is combined with diabetes, the blood pressure value can also be moderately relaxed, as hypertension combined with diabetes should be strictly controlled at 130/80mmHg or less. When applying for hypertension, if you complete the ambulatory blood pressure, after the doctor (tertiary hospital) has issued a certificate to the medical insurance (medical insurance office of each tertiary hospital) through the information network for certification, you can go to the doctor who issued the certificate to certify and sign for a special outpatient clinic in the community or a hospital below the second level.
