在2017中国国际心力衰竭大会(CIHFC)暨中国医师协会心力衰竭专业委员会年会上,来自中国医学科学院阜外医院的张宇清教授为我们带来了“心力衰竭患者的血压管理问题”的精彩报告。

Framingham研究分析了3400名男性和4199名女性,随着血压水平从低到高,心衰的的发生率增长了近一倍。

Hazard ratios for mortality associated with a 10 mm Hg increase in systolic blood pressure (SBP).
In the pooled heart failure studies, a 10 mm Hg increase in SBP implies a 13% decrease in mortality. Conversely, in the non-heart failure population, an increase in SBP is associated with a poorer prognosis.

J-curve between SBP & Heart failure
◆The effect of a higher SBP is most marked in populations with a lower starting SBP, with an 18% lower mortality in the lowest tertile (mean SBP 109) and a 10% decrease in the highest tertile (mean SBP 145) per 10 mm Hg higher SBP.
◆It is likely that the magnitude of effect associated with an increase in SBP continues to diminish such that a 10 mm Hg increase from 160 to 170 mm Hg would confer a much smaller decrease in mortality, if any.
◆Studies included in this analysis had a maximum SBP of 158 where there was a non-significant association between SBP and mortality. It may be that a level of blood pressure is reached beyond which a further increase confers an adverse prognosis, with a J-shaped relationship between SBP and mortality.

总结
◆对心力衰竭患者血压水平的关注更应注意低血压所导致的危害;
◆心力衰竭患者的血压控制目标目前缺乏随机化临床试验的证据;
◆对射血分数保留的心衰患者降压治疗获益有限;
◆RAS抑制剂治疗心力衰竭证据充分,需从心血管事件链的早期进行干预
