The Study
The Effect of Frailty on the Efficacy and Safety of Intensive Blood Pressure Control: A Post Hoc Analysis of the SPRINT Trial
This study looked at people who were prescribed blood pressure medicine and saw that some of them had falls or dizziness afterward. But it didn’t randomly assign who got the medicine — so we can’t be sure the medicine caused the falls. It just shows that people who got the medicine were more likely to have these problems, but maybe they were already sicker or more likely to fall anyway.
Analysis score
Maximum 72 for a cohort study.
Where the score came from
This study looked at older people with high blood pressure and asked: does being frail (weak, tired, or sickly) change whether lowering blood pressure very tightly helps or hurts?

Quality score
Groups of people are followed over time to see who develops an outcome. Strong for identifying risk factors and associations, but cannot prove causation as firmly as RCTs.
Key takeaways
Summary
Based on the study abstract and findings.
- 1This means even frail older adults can safely benefit from aggressive blood pressure treatment — they don’t need to be treated less aggressively just because they’re frail.
- 2Frail people had more heart problems overall, but lowering their blood pressure to below 120 mm Hg helped them just as much as it helped non-frail people, without causing more falls or dizziness.

In older adults, how frail a person is matters more than their age when deciding whether lowering blood pressure to below 120 mm Hg is safe and beneficial.
In older adults with high blood pressure, taking blood pressure medication does not increase the risk of breaking a bone, even though these medications may lead to more falls, low blood pressure, or fainting.
In adults aged 40 and older with high blood pressure, starting antihypertensive medication is linked to a higher rate of hospitalizations or deaths from falls, with a greater increase in people with dementia than in those without dementia.
