Compliance of Blood Pressure and Lipid in Hypertensive Patients Under the Management of Hospitals at Different Levels

Study Overview
=================
Brief Summary
-----------------
This is a multi-center, prospective cohort study that collects only diagnostic and therapeutic data in subjects but does not interfere with treatment.

Detailed Description
-----------------
The study aims to assess blood pressure and lipid levels, the use of lipid-lowering and antihypertensive drugs, and treatment compliance and adverse events in hypertensive outpatients of 30 hospitals of different levels, following them up for 1 and 3 months after treatment, respectively. The study would reveal the compliance of blood pressure and lipid levels in hypertensive patients under management of hospitals at different levels, and analyze factors affecting blood pressure or lipid levels associated with treatment compliance. Therefore, the study would provide clinical data from the real world for future prevention and control of CVD in China.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The primary endpoint will be compliance of blood pressure in hypertensive patients after 3 months of treatment in hospitals at different levels. | Blood pressure measurement: Blood pressure in both upper arms will be measured with a sphygmomanometer, with the patient in the sitting position. The mean value of three tests will be used for statistics. When left and right upper arms show different blood pressures, the higher value will be used for statistics. | 3 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of outpatients with abnormal blood lipid levels in hospitals at different levels | On a CardioChek dry-type biochemical analyzer, the levels of total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) in fingertip blood samples will be measured after 12-h fasting | 3 months | 
| Achievement rate of blood lipid levels in hypertensive and dyslipidemic patients after 3 months of treatment in hospitals at different levels | Achievement rate of blood lipid levels in hypertensive and dyslipidemic patients after 3 months of treatment in hospitals at different levels | 3 months | 
| Compliance of patients towards antihypertensive and lipid-lowering treatments in hospitals at different levels | Compliance of patients towards antihypertensive and lipid-lowering treatments in hospitals at different levels | 3 months | 
| Factors affecting blood pressure and lipid compliance in different hospitals, such as patient adverse events | Factors affecting blood pressure and lipid compliance in different hospitals, such as patient adverse events | 3 months | 
| Achievement rate of blood pressure in hypertensive patients under different levels of hospital management after 1 month of treatment | Achievement rate of blood pressure in hypertensive patients under different levels of hospital management after 1 month of treatment | 1 months |
