Dear Participant,
Your longstanding participation in and support of the Systolic Blood Pressure Intervention Trial
(SPRINT) and SPRINT MIND 2020 continues to reap great benefit for citizens of our nation and the world.
We are so very grateful that you participated. We are now excited to share the latest discoveries
as a result of your participation.
To recap our journey together over the past 14 years, you may recall that in September 2015 we
notified you and all of our SPRINT volunteers about the main study results:
We found that treating individuals to a systolic blood pressure goal of less than 120 mm Hg
(compared to 140 mm Hg) for only 3½ years resulted in a 30% reduction in risk of hypertension
complications such as heart attack, heart failure, stroke or death due to heart problems.
Then in May 2019, we reported the first results from the cognitive portion of SPRINT and the impact
lower blood pressure had on brain health:
Treating individuals to a systolic blood pressure goal of less than 120 mm Hg (the intensive control)
is better for your brain health. Volunteers in the 120 mmHg treatment group had about a 20% reduction
in cognitive decline or dementia compared to participants in the standard treatment group (goal = 140 mmHg).
The early cognitive decline is also known as Mild Cognitive Impairment (MCI), a precursor of dementia,
including Alzheimer’s dementia, making these results far reaching in their importance.
SPRINT was the first research study to show definitively that something can be done to prevent
early decline in cognition (memory and thinking skills).
Over the past 5 years, many of you – 4,232 in total – allowed us to contact you by phone to administer
some additional questions about memory and thinking skills.
In December 2023, we completed our final participant phone call, and the results remain very
similar to those in 2019 and, most importantly, confirm:
The benefit of treating high blood pressure to reduce the risk for developing memory impairment
extends for many years into the future. This is wonderful news, is something everyone can try to
achieve, and is far less expensive than the new treatments recently approved for Alzheimer’s disease.
So, treating high blood pressure is by far the most economical and proven approach to reducing your
risk for memory loss and dementia.
These important SPRINT MIND 2020 results are being shared with the larger medical community and
will be published soon in a scientific journal.
Your commitment to SPRINT and SPRINT MIND 2020 was essential to helping us discover the answer to
this important question about blood pressure treatment and the long-term effects that lowering
blood pressure has on brain health. All of this would not have happened without you.
Please continue to work with your doctor to keep your blood pressure in good control.
Thank you for taking the time to read this letter and for being part of an incredibly important
study that has changed the way doctors treat blood pressure.
Sincerely,
The SPRINT Research Team
