Tight Blood Pressure Control Both Healthy And Cost-Effective, Projections Say

WEDNESDAY, Aug. 20, 2025 — Tight control over blood pressure is not only good for patients, but is also cost-effective health care, a new study says.

Controlling blood pressure to below 120 systolic prevents more heart attacks, strokes, cases of heart failure and other heart-related health problems, compared with higher targets, researchers report in the Annals of Internal Medicine.

It’s also cost-effective, with tight blood pressure control increasing treatment expenses only slightly, researchers found.

“This study should give patients at high cardiovascular risk and their clinicians more confidence in pursuing an intensive blood pressure goal,” lead researcher Karen Smith, an investigator at Brigham and Women’s Hospital in Boston, said in a news release.

“Our findings suggest the intensive less than 120 mm/Hg target prevents more cardiovascular events and provides good value, and this holds true even when measurements aren’t perfect,” she said.

Current blood pressure guidelines define high blood pressure at 130 systolic or higher. Systolic blood pressure is the pressure within blood vessels during a heartbeat.

Normal blood pressure is less than 120 systolic, and blood pressure between 120 and 129 systolic is considered elevated, according to the American Heart Association.

For the new study, researchers combined data gathered between 2013 and 2018 by the National Health and Nutrition Examination Survey, the groundbreaking Systolic Blood Pressure Intervention Trial (SPRINT), and other published studies.

The team used this data to simulate lifetime heart health risks for patients over 50 years old whose systolic blood pressure was controlled to less than 120; less than 130; or less than 140.

Researchers also considered the potential risk of serious side effects posed by blood pressure medications, and accounted for common errors made in regular blood pressure readings.

Even when including occasionally erroneous blood pressure readings, the researchers’ model found that the 120 blood pressure target prevented more heart health problems than the 130 target.

The lower target also was more expensive, due to more prescriptions and doctor visits, and led to more adverse events related to treatment, such as falls, kidney damage, low blood pressure and slow heart beat, researchers found.

Nevertheless, the 120 target remained cost-effective compared to the higher targets, researchers concluded.

For example, the target of less than 120 was associated with a cost of $42,000 per life-year gained, only $1,300 more than the 130 target, results show.

However, such tight blood pressure control isn’t necessarily a good idea for everyone, Smith said.

“Given the additional risk of adverse events related to antihypertensives, intensive treatment will not be optimal for all patients,” Smith warned. “Patients and clinicians should work together to determine the appropriate medication intensity based on patient preferences.”
