The Claim
In frail elderly individuals over 80 years of age, systolic blood pressure below 130 mm Hg in the presence of polypharmacy is associated with increased all-cause mortality.
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.
Frail adults over 80 with low systolic blood pressure (below 130 mm Hg) and taking multiple medications have a higher rate of death from any cause.
See the scientific wording
In frail elderly individuals over 80, systolic blood pressure below 130 mm Hg with polypharmacy is associated with increased all-cause mortality.
When frail older people take many medications that lower blood pressure, their blood pressure drops too low for their weakened heart and stiff blood vessels to maintain enough flow to the brain and organs. This causes the brain and other organs to receive insufficient oxygen and nutrients, leading to cell stress, organ dysfunction, and death.
What the research says
3 studiesIn very old, frail people living in nursing homes, those with low blood pressure (under 130) who are taking two or more blood pressure pills are much more likely to die within two years than those with the same low blood pressure but fewer pills.
In older people taking many medications, having blood pressure too low (under 130) makes them more likely to feel dizzy or faint, which can lead to falls and even death. The study shows this risk goes up even more when they take 10 or more pills.
