血圧は両腕で測定すべきだと示唆する結果に
左右の腕で測定した血圧の差が，血管病の指標となりうることが明らかになった。英国の研究者が28本の関連論文を検討した結果だ。左右の収縮期血圧の差が15 mmHg以上であることが，末梢血管疾患の危険性が高いこと，脳血管疾患が既に存在する危険性が高いこと，心血管障害による死亡および死亡全般の危険性が高いことと関連していた。末梢血管疾患は，脚に血液を供給する動脈に狭窄や硬化を生じる疾患で，脳血管疾患は脳への血液供給に影響し，認知症などと関わる。末梢血管疾患との関連性は左右差が10 mmHgからでも認められた。（吉田素子）
Review Suggests Differences in Blood Pressure between Arms Could Indicate Vascular Risk
A systematic review and meta-analysis carried out by researchers at the University of Exeter Peninsula College of Medicine and Dentistry (PCMD), has found that differences in systolic blood pressure between arms could be a useful indicator of the likelihood of vascular risk and death.
The findings add support to the calls for both-arm blood pressure checks to be performed as standard.
The review is published in The Lancet online and the study is supported by the Royal College of General Practitioners, the South West GP Trust and the National Institute for Health Research Peninsula Collaboration for Leadership in Applied Health Research and Care.
The study reviewed 28 papers covering difference in systolic blood pressure between arms. It found significant evidence to suggest that a difference of 15 mmHg or more was associated with increased risk of: peripheral vascular disease (the narrowing and hardening of the arteries that supply blood to the legs and feet); pre-existing cerebrovascular disease (affecting the blood supply to the brain and often associated with cognitive issues such as dementia); and mortality, both as a result of cardiovascular problems and generally.
The risk of peripheral vascular disease was also increased at a difference of 10mm Hg or more.
The findings further support the need for both-arm blood pressure checks to be the norm -- not least because most cases are ‘clinically silent’ and such checks would better identify those at risk.
