Eur Heart J:心血管事件高危的高血压患者,血压应控制在140/90mmHg?还是130/80mmHg?

2015-11-28 phylis 译 MedSci原创

目的:最近高血压指南建议,心血管事件(CV)风险较高的高血压患者,应将血压降低到140/90mmHg,先前指南支持高血压目标值降至130 / 80 mmHg。然而,这是否是最佳的治疗策略尚有争议。方法和结果:长期应用缬沙坦抗高血压评估试验中,将CV高危的高血压患者分为亚组:(i) 治疗随访期间BP降至140/90或<130 / 80 mmHg的百分比,或(ii) 整个治疗期间平均收缩压或舒张压(S

目的:最近的高血压指南建议,心血管事件(CV)风险较高的高血压患者,应将血压降低到140/90mmHg,但是先前指南支持的目标值是降至130 / 80 mmHg。因此,140/90mmHg是否是最佳的治疗策略尚有争议。

方法和结果:长期应用缬沙坦抗高血压评估试验中,将CV高危的高血压患者分为亚组:(i) 治疗随访期间BP降至140/90或<130 / 80 mmHg的百分比,或(ii) 整个治疗期间平均收缩压或舒张压(SBP/DBP)或者高至事件发生。

随访期间BP<140/90mmHg的百分比从<25 增至≥75%, CV事件的发生率及死亡率、特定CV事件的发生(心肌梗死、心衰及卒中)、各种原因的死亡率显著下降。BP<130/80mmHg的随访百分比进行性增加,除了卒中发生下降增加,其他事件的发生未见显著性下降增加。

校正基线风险差异后,BP<140/90mmHg(而不是BP<130/80mmHg)随访的百分比增加与事件发生下降相关。最后,与治疗时平均SBP≥140或DBP≥90mmHg相比,平均SBP为130-139或DBP为80-89mmHg的患者所有事件发生的风险显著下降,然而,治疗SBP <130 mmHg 或DBP <80 mmHg时,卒中发生的风险下降增加,其他事件的发生并未下降增多,与较高血压控制组相比,其他事件发生的风险相似,或者仅有轻度的升高。

结论:CV高风险的高血压患者,不管是按照随访BP目标值的比例或按照治疗时的平均血压值,将BP控制连续降低至<140/90益处显著增加。将BP值降至130/80 mmHg仅使卒中发生的风险降低增加,其他预后发生的风险相似或轻度升高。因此,除了患者卒中发生风险较高时,CV高危的患者BP控制降低的增加可能并未增加潜在的优势。
