Study Details

Study Description

Brief Summary

SMART-BP is a randomized, controlled study in which hypertensive patients are allocated to self monitoring of blood pressure monitoring (SMBP) only group or SMBP with mobile App based feed-back algorithm (SMBP-App) group. The App based feed-back algorithm will provide the patients with instruction in response to the measured BP value, e.g. remind of taking drug, if high blood pressure is detected.

The primary outcomes are mean systolic BP change and drug compliance at 12-weeks. Secondary endpoints include mean diastolic BP change at 12-week, mean systolic and diastolic BP change at 12 and 24 weeks, and drug compliance.

Detailed Description

This trial is a prospective, randomized, open-label, multicenter trial to evaluate the efficacy of SMBP with mobile health application (SMBP-App) compared with SMBP alone.

Patients with hypertension will be randomly assigned to SMBP-App (intervention) and SMBP along (control) groups. In SMBP group the patients perform home blood pressure measurement and usual care. In SMBP-App group the patients perform home blood pressure and receive extra alarm and instructions from the mobile application in response to the obtained blood pressure value.

The aim of this study is to evaluate whether SMBP-App is superior to SMBP alone in terms of blood pressure reduction and improved drug compliance in patients with hypertension.
