The Claim

The cardiovascular benefit of targeting systolic blood pressure below 120 mm Hg does not extend to individuals with diabetes, prior stroke, or frailty.

Description
3 studies reviewed
In plain English

Lowering systolic blood pressure below 120 mm Hg reduces cardiovascular risk in the general population, but this benefit does not occur in people with diabetes, prior stroke, or frailty.

See the scientific wording

The cardiovascular benefit of targeting systolic blood pressure below 120 mm Hg is not generalizable to individuals with diabetes, prior stroke, or frailty.

Why this might work

In people with diabetes, prior stroke, or frailty, blood vessels are already damaged and cannot repair themselves as well. When blood pressure is pushed very low, the vessels become too stressed and cannot adjust properly, so the heart and brain do not get better protection from damage.

What the research says

3 studies
  1. Study: Lowering systolic blood pressure to less than 120 mm Hg versus less than 140 mm Hg in patients with high cardiovascular risk with and without diabetes or previous stroke: an open-label, blinded-outcome, randomised trial.

    The study found that lowering blood pressure below 120 mm Hg helped prevent heart attacks and strokes even in people with diabetes or prior stroke—exactly the opposite of what the claim says. It worked just as well for them as for others.

  2. Study: The Impact of frailty on the effectiveness of intensive blood pressure control for patients with type 2 diabetes: a secondary analysis of a randomised controlled trial

    The study found that even in older, frail diabetic patients, lowering blood pressure below 120 mm Hg still reduced heart attacks and strokes — just like in non-frail patients. So, frailty doesn’t block the benefit, which goes against the claim.
