简要总结
This trial aims to assess, in patients aged ≥50 years with an average baseline SBP ≥130 mmHg and a previous history of cardiovascular diseases or at high vascular risk, the effects on the incidence of major cardiovascular events during the scheduled treatment period of greater reduction in blood pressure with a SBP target <120 mmHg versus <140 mmHg.
详细描述
This study is a multicenter, open-label, randomized controlled trial, which will randomize participants aged ≥50 years with an average baseline SBP ≥130 mmHg and a previous history of cardiovascular diseases or at high vascular risk. The study will compare the effects on the incidence of major cardiovascular events of allocation to achieve an intensive SBP goal (SBP <120 mmHg) with a standard SBP goal (SBP <140 mmHg) in four years of follow up.

- •Current smoking (smoke more than a cigarette every day in the past 12 months)
排除标准

研究组 & 干预措施
Intensive treatment group
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.
干预措施: Intensive BP treatment group (Drug)
Standard treatment group
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.
干预措施: Standard BP treatment group (Drug)
