The Claim
Intensive systolic blood pressure control targeting below 120 mm Hg increases the absolute risk of composite kidney injury by approximately 2% in severely frail patients compared to standard blood pressure control, with no significant difference in relative risk across frailty levels.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In severely frail patients, lowering systolic blood pressure to below 120 mm Hg increases the absolute risk of kidney injury by about 2% compared to standard blood pressure control, with no difference in relative risk across levels of frailty.
See the scientific wording
Intensive systolic blood pressure control targeting below 120 mm Hg increases the absolute risk of composite kidney injury by approximately 2% in severely frail patients compared to standard control, with no significant difference in the relative risk across frailty levels.
When blood pressure drops too low in very frail people, the kidneys receive less blood flow, which starves the tiny tubes inside them of oxygen and causes damage.
What the research says
1 studyLowering blood pressure very aggressively to below 120 slightly increases the chance of kidney problems in very frail older adults by about 2%, but this small increase happens at about the same rate whether someone is frail or not — the study found this exact pattern.
