This study aims to evaluate the effect of intensive treatment (a target clinic based systolic blood pressure(BP) <120mmHg) on 24-hour ambulatory blood pressure and home blood pressure, as well as the effect on White-coat uncontrolled hypertension and masked uncontrolled hypertension, compared with standard treatment (a target clinic based systolic BP <140mmHg).
This study aims to evaluate the effect of intensive treatment (a target clinic based systolic BP <120mmHg) on 24-hour ambulatory blood pressure and home blood pressure, as well as the effect on White-coat uncontrolled hypertension and masked uncontrolled hypertension, compared with standard treatment (a target clinic based systolic BP <140mmHg). The population of this study is from an ongoing multi-centre open label clinical trial which evaluated the effect of intensive systolic hypertension treatment on major cardiac events (ESPRIT study). ESPRIT study enrolled patients with high risk of cardiovascular disease, who were aged≥50 years old with a systolic BP≥130 mmHg, and assigned them randomly to intense hypertension group (a target clinic based systolic BP <120mmHg) or standard hypertension group (a target clinic based systolic BP <140mmHg), with a 3-year follow-up, evaluating the effect of intense hypertension treatment on major cardiac events.
From those eligible ones for the trial, the investigators plan to select 710 to participate in this study. During the 2-3 years of follow-up of the main trial, the participants will be monitored using 24-hour ambulatory blood pressure monitoring, meanwhile one-week home blood pressure monitoring will also be conducted. The two monitoring approaches will be performed twice; once every half year, based on which this study will evaluate the effect of intensive hypertension treatment on 24-hour ambulatory blood pressure and home blood pressure, as well as the effect on White-coat uncontrolled hypertension and masked uncontrolled hypertension.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Intensive BP Arm | Experimental | Participants randomized into the Intensive treatment group will have a goal of SBP <120 mmHg. A two- or three-drug regimen should be initiated at randomization for most participants. Drug doses should be increased and/or additional antihypertensive medications should be added at each visit in the intensive treatment group, usually at monthly intervals, until the participant's goal of <120 mmHg has been reached or the local investigator decides no further antihypertensive medications may be added. |
|
| Standard BP Arm | Active Comparator | Participants randomized into the Standard treatment group will have a goal of SBP <140 mmHg. It is expected to achieve a SBP of 135-139 mmHg in as many participants as possible. Medication dose titration or addition of another drug is indicated if SBP is ≥160 mmHg at a single visit or is ≥140 mmHg at two consecutive visits. Down titration should be carried out if the SBP is <130 mmHg at a single visit or <135 mmHg at two consecutive visits. |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Intensive BP Arm | Drug | Participants in the Intensive BP treatment group have a goal of SBP <120 mmHg. It is recommended to provide long-acting antihypertensive medications, that is once daily, unless other medication delivery frequency is needed. The local investigator may select among the available study antihypertensive medications. Other drugs not supplied by the trial may also be used as the investigator determines appropriate. One or more medications from the following classes of agents will be provided by the study for use in managing participants in both randomization groups to achieve study goals: Angiotension converting enzyme (ACE)-inhibitors;Angiotension receptor blockers (ARBs); Thiazide-type diuretics; Loop diuretics; Potassium-sparing diuretics; Beta-blockers; Calcium channel blockers (CCBs); Direct vasodilators; Alpha1-receptor blockers; Sympatholytics |
