Eligibility Criteria
-----------------
Inclusion Criteria: Patients aged ≥ 18 years with confirmed diagnosis of hypertension Office systolic blood pressure (SBP)≥140 mmHg and/or diastolic blood pressure (DBP)≥90 mmHg, or ambulatory blood pressure monitoring (ABPM) indicating 24- hour SBP ≥130 mmHg and/or DBP ≥80 mmHg and/or daytime SBP ≥135 mmHg and/or DBP ≥85 mmHg and/or nocturnal SBP ≥120 mmHg and/or DBP ≥70 mmHg.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Intervention<br>The intervention group will be enrolled into WeChat platform. Participants will receive health education materials, monitor blood pressure at home and sent the blood pressure record to the platform and consult doctors online via platform. | Other: WeChat platform group<br>* Participants in the intervention group will receive educational messages related to hypertension, such as impact of hypertension on cardiovascular system, lifestyle adjustment and side effects of antihypertensive drugs. Participants will be reminded to take their blood pressure regularly and enter the blood pressure readings into the WeChat platform. If participants enter extremely high or low readings, they will be asked to seek medical help from doctors. Participants can also consult doctors online via WeChat platform by text and voice messages, or voice calls.<br>|
| No Intervention: Control<br>Control group will receive usual care and follow up in hospitals and community health centers. | |
