Lower blood-pressure target did not cut cardiovascular events

Major cardiovascular events occurred in 6.0% with intensive therapy versus 6.7% with standard therapy over a median 4.0 years in patients with type 2 diabetes.

Santo et al.
Studied:
Randomized trial in 9,476 patients with diabetes and high cardiovascular risk, median 4.0 years (Multicenter, registered NCT04040634)
What changed:
Major cardiovascular events did not differ: 6.0% with intensive therapy versus 6.7% with standard therapy
The catch:
Patients and clinicians knew treatment targets, potentially influencing decisions to hospitalize patients
In the record:
The 21st paper on intensive blood pressure lowering with results in people; 28 on record in all.
Why it’s aging research:
It bears on staying healthy in midlife and later life.

In Brazil, 9,476 ethnically diverse patients with type 2 diabetes, elevated blood pressure and high cardiovascular risk took part in an open-label, randomized trial. Their average age was 64.7 years, and 62.0% were women. Treatment targeted systolic pressure—the upper blood-pressure reading—below 120 mm Hg or below 140 mm Hg.

Over a median 4.0 years, the lower target did not reduce the combined outcome of cardiovascular death, nonfatal heart attack or stroke, or hospitalization for unstable angina (new or worsening heart-related chest pain) or heart failure (when the heart cannot pump blood well). Serious medical events occurred in 706 patients (14.9%) receiving intensive therapy and 693 (14.6%) receiving standard therapy.

Why it matters

For older adults with type 2 diabetes and high cardiovascular risk, the trial addressed how low to aim when managing blood pressure.

Caveats

Patients and clinicians knew the assigned targets, and the range of likely effects included no difference. The findings concern people with type 2 diabetes and high cardiovascular risk, not necessarily people without diabetes or at lower risk.
