High blood pressure, also called hypertension, is one of the most common long-term health problems in the world.
Millions of people live with it, and many do not even know they have it because it often causes no obvious symptoms.
For this reason, high blood pressure is sometimes called the “silent killer.” If it is left untreated, it can slowly damage blood vessels and increase the risk of heart attacks, strokes, heart failure, kidney disease, and even vision problems.
Blood pressure is measured using two numbers. The first number, called systolic blood pressure, measures the pressure in the arteries when the heart pumps blood. The second number, called diastolic blood pressure, measures the pressure when the heart relaxes between beats.
For many years, doctors often aimed to keep systolic blood pressure below 140 mmHg in older adults. However, scientists have continued to study whether lowering blood pressure even further could provide greater health benefits.
A new study published in the journal Cardiovascular Innovations and Applications suggests that aiming for a systolic blood pressure below 130 mmHg may better protect adults aged 60 years and older. The findings add to the growing discussion about the best blood pressure targets for older people.
The researchers used a method known as a Bayesian network meta-analysis. Although the name sounds complicated, it simply means they combined and compared results from several high-quality clinical studies to gain a stronger understanding than any single study could provide. In total, they analyzed data from six clinical trials involving older adults with high blood pressure.
The researchers compared people who were treated to different blood pressure goals. They then looked at how often participants experienced major health problems such as heart attacks, strokes, heart failure, cardiovascular death, or death from any cause.
The results showed that older adults whose systolic blood pressure was lowered to less than 130 mmHg had a lower risk of major cardiovascular events than those whose blood pressure remained at or above 140 mmHg.
The lower blood pressure target also appeared to reduce the risk of dying from heart disease and from other causes, although these improvements were not always large enough to be considered statistically strong.
These findings suggest that tighter blood pressure control may provide extra protection for the heart and blood vessels in many older adults. By reducing the pressure placed on artery walls over many years, lower blood pressure may help prevent damage that can eventually lead to life-threatening diseases.
Even so, the researchers stressed that one blood pressure target does not fit everyone. Older adults often have different medical conditions, take multiple medications, and vary greatly in their overall health.
Some people may experience dizziness, falls, or other side effects if their blood pressure becomes too low. Because of this, doctors should continue to tailor treatment plans to each person’s individual needs rather than applying the same target to everyone.
Managing high blood pressure usually involves a combination of medicine and healthy lifestyle choices. Medicines prescribed by doctors help relax blood vessels, remove excess fluid, or reduce the workload on the heart. At the same time, healthy daily habits can make these medicines work even better.
Eating a heart-healthy diet is one of the most effective ways to lower blood pressure. Experts recommend reducing salt intake, eating plenty of fruits and vegetables, choosing whole grains, beans, nuts, and lean protein, and limiting foods that are high in saturated fat and added sugar.
Foods rich in potassium, such as bananas, potatoes, spinach, beans, and yogurt, may also help support healthy blood pressure for many people.
Regular physical activity is another important step. Walking, cycling, swimming, dancing, or other moderate exercise for at least 150 minutes each week can help lower blood pressure naturally.
Maintaining a healthy body weight, quitting smoking, limiting alcohol, managing stress through relaxation techniques, and getting enough quality sleep are also important parts of blood pressure control.
Because high blood pressure usually has no warning signs, regular blood pressure checks are essential. Early detection allows treatment to begin before serious complications develop.
This new research provides more evidence that aiming for a systolic blood pressure below 130 mmHg may help many older adults reduce their risk of heart disease and stroke. However, treatment decisions should always be made together with a healthcare provider, taking into account a person’s overall health, medical history, and personal circumstances.
As scientists continue to learn more about the best ways to manage hypertension, one message remains clear. Keeping blood pressure under control through regular medical care, healthy habits, and appropriate treatment is one of the most effective ways to protect the heart, brain, kidneys, and overall health throughout later life.
If you care about high blood pressure, please read studies that drinking tea could help lower blood pressure, and early time-restricted eating could help improve blood pressure.
