收缩压干预试验(systolic blood pressure intervention trial,SPRINT)发现:与收缩压<140mm Hg(1mm Hg=0.133kPa)比较,一些高龄的高风险患者可能从收缩压<120 mm Hg的靶目标中获益。但SPRINT中采用的血压靶目标及测量方法与日常实践中心血管病预后的关系仍不明确。SPRINT采用自动诊室血压测量方法,要求患者单独安静休息,采用电子示波血压计多次自动测量并记录血压。纳入年龄≥66岁,接受降压治疗且平均随访4.6年的安大略社区居
Systolic blood pressure intervention trial (SPRINT) found that some older, high-risk patients may benefit from target targets with systolic blood pressure <120 mm Hg compared to systolic blood pressure <140 mm Hg (1 mm Hg = 0.133 kPa) . However, the relationship between the blood pressure target and measurement methods used in SPRINT and the prognosis of cardiovascular disease is still unclear. SPRINT adopts the automatic clinic blood pressure measurement method, requiring the patient to rest quietly alone, using an electronic oscillometric sphygmomanometer to automatically measure and record blood pressure many times.
