About this trial
The primary purpose of the study is to explore whether a lower home blood pressure target (125/75 v.s. 135/85 mmHg) would be beneficial to elderly treated hypertensive patients in terms of reduced incidence of cardiovascular events. The study also aims to promote the application of standardised and information-based home blood pressure monitoring in community hypertension management.
