Hypertension is the leading preventable risk factor of cardiovascular disease globally and in China. Unparalleled to remarkable increase of hypertension burden in China, blood pressure(BP) control is inadequate. A political public health project, "Hypertension Prevention and Control Initiative in China(Chronic Disease Demonstration District Construction)", was initiated in October 2019 for explore a feasible and reproducible archetype for hypertension management and to improve the registration, management, treatment and control rates of hypertension in China. The project is designed to consecutively implement health service strategies in 40 pilot counties covering 31 provinces and around 200,000 hypertension patients in mainland China, via the National Medical Alliance for Hypertension(NMAH). The Hypertension Registry study aims to registry, follow up and observe the clinical features, treatment, blood pressure control and outcomes of all hypertension patients managed in the "Hypertension Prevention and Control Initiative in China" project.

Objective: The study aims to investigate the clinical features, treatment, blood pressure control and outcomes of hypertension patients managed in the "Hypertension Prevention and Control Initiative in China" project.

Study Type: A national, multicenter, observational, prospective cohort study.

Study Design: The cardinal contents of this registry study are as follows:

Introduce the Digital Information System and train in completing case report forms.

Collect sociodemographic information, lifestyle behaviors, self-reported personal medical history, BP, anthropometric measurements, medication at registration, laboratory investigations of hypertension patients managed in the "Hypertension Prevention and Control Initiative in China" project. Build a baseline database of hypertension patients.

Gather the follow up information including general, clinical, therapeutic, prognostic data of all recruits at 3-month intervals over 2 years and build up the follow-up database.

Data management, quality control and statistic analysis: Digital Information Platform for data capture, document and cloud computing has been built and the investigators will manage and analyze data in align with key indicators. The investigators have invited professional statistic analysts to assist analyzing data and a third party to supervise data quality.

Ethics: The Ethics Committee of Fuwai Hospital approved this study. Informed consents before patient enrollment are required.

Inclusion Criteria:

1. Age ≥ 18 years.
2. Residing in the local administrative area for at least 6 months.
3. Hypertension：defined as systolic blood pressure (SBP) ≥140 mmHg and/or /diastolic blood pressure (DBP) ≥90 mmHg and/or use of antihypertensive medication within two weeks.
4. Informed consent.

Exclusion Criteria:

1. patients under pregnancy or lactation.
2. patients with severe liver or renal diseases.
3. patients with history of malignant tumor.
4. patients with mental illness that impair their consent.

The study recruits patients managed in the "Hypertension Prevention and Control Initiative in China" project. Eligible criteria for the registry study are equal to the inclusion and exclusion criteria for the project. All adult hypertension residents are eligible except for patients cannot be managed at local primary care centers and needing to be transferred for specialist management or residence management.
