Outcome Measures
Primary Outcomes (1)
Attainment rate to the target blood pressure.
After collecting all Patient Record Form.
Secondary Outcomes (2)
Dropout rate will be estimated during the follow-up period after the hypertension treatment. Attainment to the target blood pressure will be investigated according to concomitant diseases.
After collecting all Patient Record Form.
Change in DBP/SBP value during the follow-up period will be addressed. Change in the DBP/SBP value will be investigated according to the risk factors and concurrent disease.
