When most people check their blood pressure, they look at two numbers: the top number, called systolic pressure, and the bottom number, called diastolic pressure.
These numbers show how hard your heart is working and how much resistance the blood faces as it flows through your arteries.
But there’s another important number to consider called pulse pressure. This is the difference between your systolic and diastolic blood pressure. For example, if your blood pressure is 120 over 80, your pulse pressure is 40.
It might sound simple, just one number minus another, but pulse pressure can actually tell us a lot about our heart health. A high pulse pressure—say, more than 60—is a warning sign. It means your heart has to work much harder to push blood through stiff or narrowed arteries. This added strain can cause long-term damage to your heart and blood vessels.
As we get older, our arteries tend to get stiffer. This natural aging process can raise pulse pressure. That’s why doctors pay more attention to pulse pressure in older adults. Research has shown that people with a high pulse pressure are more likely to have heart attacks, heart failure, and strokes.
This happens because a wide gap between the top and bottom blood pressure numbers may point to problems like atherosclerosis. That’s when plaque builds up in the arteries, making them narrow and less flexible. When arteries are stiff, blood doesn’t flow as easily, which can affect the heart and other parts of the body.
So what can you do? Most blood pressure treatments focus on bringing down the top number (systolic) and the overall reading. But now, more experts believe we should also think about pulse pressure, especially in older people or those who have high systolic blood pressure but normal diastolic pressure.
To help manage pulse pressure, you can start by making heart-healthy lifestyle changes. Eating more fruits, vegetables, and whole grains can help. Exercise is another great way to keep your heart and arteries healthy. Keeping a healthy weight and not smoking are also important steps.
Some people may need medication. Certain blood pressure drugs, like ACE inhibitors and calcium channel blockers, may help reduce the stiffness of the arteries. This can lead to a lower pulse pressure and better heart health.
In short, pulse pressure is an important piece of the puzzle when it comes to understanding and managing blood pressure. It’s not just about the top and bottom numbers anymore. Paying attention to this middle number—the difference—can help doctors and patients take better care of the heart.
As scientists continue to study pulse pressure, we’re learning just how useful this simple number can be in protecting our health and preventing serious heart problems.
