High blood pressure affects millions of older adults around the world and is one of the leading causes of heart attacks, strokes, heart failure, and other serious health problems.
As people age, blood vessels often become less flexible, making it more common for blood pressure to rise. Because of this, doctors and researchers have long debated the best blood pressure target for older adults.
While lowering blood pressure can help protect the heart and blood vessels, lowering it too much may sometimes cause problems such as dizziness, falls, or weakness. Finding the right balance is an important part of healthy aging.
A recent study has provided new insight into this question. Instead of carrying out a completely new clinical trial, researchers carefully reviewed and combined information from six previously published studies.
By bringing together data from multiple studies, they were able to examine trends across a larger number of older adults and gain a clearer picture of how blood pressure levels may affect heart health.
The researchers focused on systolic blood pressure, often called SBP. This is the top number in a blood pressure reading and measures the pressure inside the arteries when the heart pumps blood to the body. For example, in a reading of 130 over 80, the number 130 represents the systolic blood pressure.
To better understand the relationship between blood pressure and heart health, the researchers divided the results into three groups.
One group included people whose systolic blood pressure was below 130 millimeters of mercury, commonly written as mmHg. The second group included people with readings between 130 and 139 mmHg. The third group included people with readings of 140 mmHg or higher.
After examining the combined results, the researchers found a clear pattern. Older adults who maintained a systolic blood pressure below 130 mmHg experienced fewer major heart-related problems than those with higher readings.
On the other hand, people whose systolic blood pressure remained at 140 mmHg or above faced a greater risk of heart disease and other cardiovascular complications. These findings suggest that keeping blood pressure below 130 mmHg may offer important protection for the heart.
The results add to growing evidence that lower blood pressure targets can benefit many older adults. Heart disease remains one of the most common causes of death worldwide, and even small improvements in blood pressure control can have a significant impact on public health.
By reducing strain on the heart and blood vessels, lower blood pressure may help decrease the risk of heart attacks, strokes, and other serious conditions.
However, the researchers also noted that the situation is not always straightforward. Although more intensive blood pressure treatment appeared to provide benefits, the study could not prove that aggressively lowering blood pressure is the best choice for every individual.
Older adults often have different medical conditions, take multiple medications, and respond differently to treatment. What works well for one person may not be ideal for another.
Doctors are especially careful when treating older adults because blood pressure that becomes too low can sometimes cause side effects. Some people may experience dizziness, lightheadedness, balance problems, or an increased risk of falls.
For this reason, treatment decisions should always consider a person’s overall health, medical history, and daily functioning.
The study suggests that for many people aged 60 and older, aiming for a systolic blood pressure below 130 mmHg may be a reasonable goal for lowering cardiovascular risk. Still, this target should not be viewed as a one-size-fits-all rule. Healthcare professionals can help determine the safest and most effective blood pressure goal for each individual.
Medication is only one part of blood pressure management. Healthy lifestyle choices can also play a major role.
Regular physical activity, maintaining a healthy weight, reducing salt intake, managing stress, getting enough sleep, and eating a balanced diet can all contribute to healthier blood pressure levels. Some research has also explored how foods rich in potassium may help support blood pressure control.
The findings from this research contribute to an ongoing discussion about how best to protect heart health in older age. While the evidence suggests that keeping systolic blood pressure below 130 mmHg may provide important benefits for many older adults, treatment should always be personalized.
Working closely with a doctor and making healthy lifestyle choices can help people manage their blood pressure safely and support long-term heart health.
The research was based on an analysis of six previously published studies examining blood pressure targets and cardiovascular outcomes in older adults.
