What Your Blood Pressure Numbers Really Mean

High blood pressure impacts more than 1 billion people worldwide. Known as a “silent killer,” it’s estimated to be responsible for half of all cases of heart disease, stroke, and heart failure worldwide. 

February is American Heart Month, an excellent time to underscore the importance of prioritizing your heart health and how managing blood pressure can significantly protect your heart and keep it strong for years to come. 

At Bridgewater Primary Care & Cardiology, LLC, our skilled team of primary and specialty care providers focuses on preventive care and early detection. Under the leadership of board-certified cardiologist and internist John Terzian, MD, FACC, our team routinely measures, monitors, and manages patient blood pressure. 

Knowing what your blood pressure readings mean can help you understand your risk and take action to prevent serious health complications such as heart disease and stroke. 

What the numbers represent

The heart pumps oxygenated and nutrient-rich blood through a network of arteries, veins, and capillaries that carry blood continuously to your body’s organs and tissues. With each pump and in between pumps, the force against your arteries matters. 

Too low, your body won’t receive enough blood; too high, blood vessels become damaged over time, making balance key. 

Systolic blood pressure (top number) measures the force of blood against artery walls when your heart contracts. This reflects how hard your heart is working with each beat.

The bottom number, diastolic pressure, measures the pressure in your arteries when your heart relaxes between beats. This shows how much resistance your blood vessels maintain at rest.

Both numbers matter. Persistently elevated pressure at either phase increases strain on your heart, brain, kidneys, and blood vessels.

What’s considered normal, elevated, or high

A normal blood pressure is generally defined as less than 120/80. When the systolic reading is 120-129, and the diastolic is below 80, this is considered elevated blood pressure. While not yet hypertension, it puts you at an increased risk. At this stage, lifestyle changes are often enough to turn things around.

High blood pressure, or hypertension, begins at 130/80 or higher. At this level, the risk of heart attack, stroke, heart failure, and kidney disease increases significantly. Research consistently shows that even modest elevations, if left untreated, increase long-term cardiovascular risk.

Why high blood pressure is called a “silent” condition

High blood pressure rarely causes noticeable symptoms until readings are dangerously high. You may feel fine while damage occurs without your knowledge. This is why many Americans with high blood pressure are unaware of it. 

Elevated pressure stiffens arteries, accelerates plaque buildup, and forces the heart to work harder to pump blood. Many patients first learn they have high blood pressure during a regular office visit, not because they feel unwell.

One reading doesn’t tell the whole story

Blood pressure fluctuates throughout the day. Stress, activity, pain, caffeine, and even poor sleep can temporarily raise readings. Our team monitors multiple readings to gain insight into your blood pressure trends over time before making a diagnosis and going over recommended management options. 

With same-day appointments, in-house lab testing, and access to advanced cardiovascular diagnostics, our providers can determine whether elevated readings reflect true hypertension or a temporary response.

What your numbers mean for your next steps

If your blood pressure is elevated or high, the next step depends on your overall health, age, family history, and other risk factors. For some people, lifestyle changes such as diet, activity, and weight management are enough. Others may need medication to protect their heart and blood vessels.

Our team offers individualized care. We focus on addressing problems early, before high blood pressure leads to damage.
