High blood pressure, also called hypertension, is one of the most common health problems in the world. It often develops slowly and may not cause obvious symptoms at first, which is why it is sometimes called a “silent” condition.
Over time, however, it can damage blood vessels and increase the risk of serious health problems such as heart attacks, strokes, and kidney disease.
For many years, doctors have used a tool that estimates a person’s risk of having a heart attack or stroke within the next 10 years. This short-term risk has been important in deciding whether someone should start taking medication. However, a new study suggests that focusing only on the next 10 years may not give the full picture.
The research, published in the journal Hypertension, introduces a new way to look at risk over a longer period of time. The study was led by Dr. Paul Muntner, a visiting professor at the University of Alabama at Birmingham. His team developed new equations that estimate both 10-year and 30-year risks for cardiovascular disease.
Cardiovascular disease refers to conditions that affect the heart and blood vessels. These include heart attacks, strokes, and heart failure. Understanding a person’s risk over both short and long periods can help doctors make better decisions about treatment.
The study found that many people may appear to have a low risk of heart problems over the next 10 years, but their risk becomes much higher when looking at the next 30 years. This is especially true for younger adults or those with early-stage high blood pressure.
High blood pressure is usually measured using two numbers. The first number, called systolic pressure, shows how much pressure is in the arteries when the heart beats. The second number, called diastolic pressure, shows the pressure when the heart is resting between beats.
Doctors classify hypertension into two main stages. Stage 1 hypertension is when the systolic number is between 130 and 139, or the diastolic number is between 80 and 89. Stage 2 hypertension is when the systolic number is 140 or higher, or the diastolic number is 90 or higher.
For people with stage 2 hypertension, doctors usually recommend medication. For those with stage 1 hypertension, the decision is more complicated and depends on overall risk.
In the past, doctors used a method called the Pooled Cohort Equations to estimate risk. This method looks at factors such as age, cholesterol levels, smoking, and diabetes to calculate the chance of having a heart attack or stroke within 10 years.
However, this approach has some limits. It does not include certain conditions like heart failure, and it does not fully reflect modern treatments such as the use of cholesterol-lowering drugs.
To improve this, researchers developed a newer tool called PREVENT in 2023. This tool provides a more complete picture by estimating both 10-year and 30-year risks. It also includes more information, such as kidney function, blood sugar levels, and social factors like income and education.
The study showed that when using the PREVENT tool, many people with stage 1 hypertension had a lower risk over 10 years but a higher risk over 30 years compared to the older method. This means that even if a person seems safe in the short term, they may still face serious health risks later in life.
These findings suggest that doctors and patients should think beyond short-term risk. Looking at long-term risk may help people take action earlier and prevent future problems.
Lifestyle changes are still the first step in managing high blood pressure. These include eating less salt, exercising regularly, maintaining a healthy weight, and avoiding smoking. However, for some people, these changes may not be enough.
In such cases, medication may be needed to control blood pressure and reduce long-term risk. Understanding the bigger picture can help people make better decisions about their health.
Overall, this study highlights the importance of looking at both short-term and long-term risks when managing high blood pressure. By doing so, patients and doctors can work together to choose the best plan for preventing serious health problems in the future.
If you care about high blood pressure, please read studies that early time-restricted eating could help improve blood pressure, and natural coconut sugar could help reduce blood pressure and artery stiffness.
For more health information, please see recent studies about added sugar in your diet linked to higher blood pressure, and results showing vitamin D could improve blood pressure in people with diabetes.
