Evidence Update
Current evidence
Intensive systolic blood pressure control targeting less than 120 mm Hg was compared with a standard target below 140 mm Hg in SPRINT adults with hypertension and elevated cardiovascular risk, excluding diabetes and prior stroke. SPRINT MIND did not demonstrate a statistically significant primary dementia reduction, while secondary MCI findings favored intensive blood-pressure control. Longer SPRINT follow-up preserves the distinction between uncertain dementia reduction and a favorable cognitive composite; the figure-label correction does not create a new result.
Among SPRINT participants aged 75 or older with high blood pressure but no diabetes or previous stroke, a more intensive blood-pressure target did not improve walking-speed decline or mobility limitations compared with the standard target. This does not prove the approaches equivalent, and it does not negate cardiovascular benefits measured in other SPRINT outcomes. Population: 2636 hypertensive adults at least 75, mean 79.9, 37.9% women; no diabetes or stroke; 2629 with defined mobility status. Species: Homo sapiens Intervention and comparator: Systolic target less than 120 mmHg Comparator: Systolic target less than 140 mmHg Endpoint: Gait-speed slope and transition to mobility limitation Reported result: Slope difference 0.0004 m/s/year (−0.005 to 0.005), P=0.88; limitation HR 1.06 (0.92–1.22). Follow-up: About 3 years
What changed
Intensive BP control has favorable secondary cognitive findings, while probable-dementia estimates remain uncertain and adverse tradeoffs matter.Intensive blood-pressure targeting did not improve gait-speed decline or mobility limitation in SPRINT participants aged at least 75.
What did not change
Longer follow-up is not a fresh independent experiment or proof of dementia prevention.Null is not equivalence and does not negate cardiovascular benefits or resolve every frailty subgroup.
Why it matters
Prevents a secondary composite from replacing the primary clinical question.
Main limitation
Early trial stopping reduced dementia power; intensive BP also had hypotension, syncope, electrolyte and acute kidney injury tradeoffs. The formal baseline-reporting correction corrects baseline Framingham-risk reporting, not these outcome estimates. Attrition and post-intervention follow-up; not independent replication. The figure-label correction corrects Figure 3 right y-axis to cumulative MCI or probable dementia; do not label it dementia alone.Null is not equivalence and does not negate cardiovascular benefits or resolve every frailty subgroup. Design: Randomized blood-pressure target comparison; ancillary physical outcomes Safety: This source does not establish comprehensive cardiovascular treatment safety; no safety claim added. Interpretation: SPRINT physical null does not refute MIND/CV evidence.
Next proof
Longer follow-up with complete cognitive ascertainment, prespecified dementia endpoints and concurrent safety assessment.Function-powered replication with adverse-event and frailty stratification.
Summary
Intensive systolic blood pressure control targeting less than 120 mm Hg was compared with a standard target below 140 mm Hg in SPRINT adults with hypertension and elevated cardiovascular risk, excluding diabetes and prior stroke. SPRINT MIND did not demonstrate a statistically significant primary dementia reduction, while secondary MCI findings favored intensive blood-pressure control. Longer SPRINT follow-up preserves the distinction between uncertain dementia reduction and a favorable cognitive composite; the figure-label correction does not create a new result.
Intelligence Take
