High blood pressure is very common in older adults and is a major cause of heart attacks and strokes. As people age, their blood vessels become less flexible, which can make blood pressure rise.
Doctors often advise older adults to control their blood pressure, but the question remains: how low should it go to protect the heart without causing harm? A recent study tried to answer this by carefully reviewing data from six earlier studies involving older adults.
Instead of running a new experiment, the researchers combined results from past research to look for clear patterns.
They focused on systolic blood pressure, also called SBP. This is the top number in a blood pressure reading and shows the pressure in the arteries when the heart beats. For example, in a reading of 120 over 80, the number 120 is the systolic pressure.
The researchers grouped older adults into three categories based on their systolic pressure levels. One group had SBP below 130 millimeters of mercury, another group had levels between 130 and 139, and the third group had levels of 140 or higher.
They then compared how often people in each group experienced major heart problems such as heart attacks, strokes, or heart failure.
The results showed a clear pattern. Older adults who kept their systolic pressure below 130 had fewer serious heart problems. Those whose pressure was 140 or higher had a greater risk of heart-related illness. This suggests that lowering blood pressure to below 130 may help protect the heart and blood vessels as people age.
However, the study also raised important questions. Lower is not always better for everyone. Some older adults may feel dizzy or weak if their blood pressure drops too much, which can increase the risk of falls.
Falls can lead to broken bones or other serious injuries. Because of this, doctors must balance the benefits of lower blood pressure with possible side effects.
Another key point is that people respond differently to treatment. Some individuals may need medication to reach a safe level, while others may control their blood pressure through lifestyle changes alone. Health conditions such as diabetes, kidney disease, or heart problems can also affect what level is safest.
For adults aged 60 and older, the study suggests that aiming for a systolic pressure under 130 may reduce the chance of heart disease. Still, personal health situations vary widely. What works well for one person may not be suitable for another. This is why medical advice should always be tailored to each individual.
Lifestyle habits also play a powerful role in blood pressure control. Eating a healthy diet rich in fruits, vegetables, and whole grains can help.
Reducing salt intake, staying physically active, maintaining a healthy weight, and managing stress are all important steps. Some research also shows that foods high in potassium, such as bananas and leafy greens, may support healthy blood pressure levels.
This study adds useful information to the ongoing discussion about blood pressure targets for older adults. While keeping systolic pressure below 130 appears helpful for many people, it should not replace professional medical guidance.
Speaking with a doctor before changing medication or lifestyle is always the safest choice. With the right balance of treatment and healthy habits, older adults can protect their hearts and maintain their independence for longer.
If you care about high blood pressure, please read studies that early time-restricted eating could help improve blood pressure, and coconut sugar could help reduce blood pressure and artery stiffness.
For more information about blood pressure, please see recent studies about added sugar in your diet linked to higher blood pressure, and results showing plant-based foods could benefit people with high blood pressure.
