The Claim

In older adults with type 2 diabetes, intensive blood pressure lowering reduces the risk of combined macro- and microvascular events less in frail individuals than in nonfrail individuals, as evidenced by a hazard ratio of 0.97 (95% CI 0.83–1.13) in frail individuals compared to 0.86 (95% CI 0.77–0.97) in nonfrail individuals.

Cause and effect
1 study reviewed
In plain English

In older adults with type 2 diabetes, aggressive blood pressure control results in a smaller reduction in combined heart and kidney complications for frail individuals compared to nonfrail individuals.

See the scientific wording

In older adults with type 2 diabetes, the benefit of intensive blood pressure lowering on combined macro- and microvascular events is attenuated in frail individuals, with a hazard ratio of 0.97 (95% CI 0.83–1.13) compared to 0.86 (95% CI 0.77–0.97) in nonfrail individuals, suggesting that aggressive blood pressure control provides less vascular protection in those with frailty.

Why this might work

In frail older adults with type 2 diabetes, reduced muscle mass and weakened kidney and liver function cause blood pressure medications to build up in the body and trigger dangerously low blood pressure and low blood sugar. These extreme drops disrupt blood vessel function and increase stress on the heart and kidneys, canceling out the benefits of aggressive treatment.

  1. Study: The Impact of Frailty on the Effectiveness and Safety of Intensive Glucose Control and Blood Pressure–Lowering Therapy for People With Type 2 Diabetes: Results From the ADVANCE Trial

    In older adults with diabetes, lowering blood pressure very aggressively helps protect the heart and kidneys—but this benefit is much weaker in people who are frail. The study found that frail people got less protection from tight blood pressure control than those who weren’t frail.
