A blood pressure reading of 144 systolic (the top number) is classified as Stage 2 hypertension, which is the more serious category of high blood pressure. Under current guidelines from the American Heart Association and American College of Cardiology, Stage 2 hypertension begins at 140 systolic or 90 diastolic, so 144 sits just above that threshold. This reading typically calls for both lifestyle changes and medication.
Where 144 Falls on the Blood Pressure Scale
Blood pressure is measured in two numbers. The top number (systolic) reflects the pressure in your arteries when your heart beats, and the bottom number (diastolic) reflects the pressure between beats. A reading of 144 systolic places you in Stage 2 hypertension regardless of what the bottom number is, because classification is based on whichever number falls into the higher category.
For context, here’s how the categories break down:
- Normal: below 120 systolic and below 80 diastolic
- Elevated: 120 to 129 systolic and below 80 diastolic
- Stage 1 hypertension: 130 to 139 systolic or 80 to 89 diastolic
- Stage 2 hypertension: 140 or higher systolic, or 90 or higher diastolic
- Hypertensive crisis: higher than 180 systolic and/or higher than 120 diastolic
If your bottom number is also 144, that’s a different and more urgent situation. A diastolic reading above 120 crosses into hypertensive crisis territory, which can cause organ damage and requires immediate medical attention. Symptoms like chest pain, blurred vision, confusion, or severe anxiety alongside a reading that high warrant calling 911.
Make Sure the Reading Is Accurate
A single reading of 144 doesn’t necessarily mean you have Stage 2 hypertension. Blood pressure fluctuates throughout the day based on stress, caffeine, physical activity, and even how you’re sitting. To confirm the reading, you need multiple measurements taken correctly over several days.
The American Heart Association recommends a specific protocol for home monitoring: sit quietly for five minutes before measuring, with your back supported, feet flat on the floor, and legs uncrossed. Your arm should rest on a flat surface with the cuff at heart level. Take two readings at least one minute apart, both in the morning and evening. Ideally, do this for seven days (28 total readings, minimum 12 over three days), then average the results. If your average still lands at or above 140, the reading is likely real.
Common mistakes that artificially inflate readings include talking during the measurement, using a cuff that’s too small, resting your arm in your lap instead of on a table, and measuring right after exercise or coffee.
What a Systolic Reading of 144 Means for Your Health
When only the top number is elevated and the bottom number stays below 80, the condition is called isolated systolic hypertension. This pattern is especially common in people over 50 and is often caused by stiffening of the arteries, though it can also result from an overactive thyroid, diabetes, heart valve problems, or obesity.
Over time, a persistently elevated systolic number raises your risk of stroke, heart disease, chronic kidney disease, and dementia. The damage is gradual. High pressure forces the heart to work harder, thickens artery walls, and accelerates the buildup of plaque in blood vessels. You won’t feel most of this happening, which is why hypertension is often called a “silent” condition.
Treatment at This Level
The 2025 AHA/ACC guidelines recommend that adults with an average blood pressure of 140/90 or higher start medication in addition to lifestyle changes. At Stage 2, the preferred approach is a combination of two blood pressure medications in a single pill rather than a single drug alone. This strategy brings blood pressure under control faster and is easier to stick with than taking multiple separate pills.
Lifestyle changes remain a core part of treatment at every stage. The most effective changes include:
- Following a DASH eating pattern, which emphasizes fruits, vegetables, whole grains, and low-fat dairy while limiting saturated fat and sodium
- Reducing sodium intake, which for most people means cutting back on processed and restaurant foods
- Increasing potassium, found in bananas, potatoes, beans, and leafy greens
- Regular moderate exercise, such as 30 minutes of brisk walking most days
- Reaching or maintaining a healthy weight
- Reducing or eliminating alcohol
- Managing stress
These changes alone can lower systolic blood pressure by 5 to 15 points in some people, but at 144, most guidelines call for medication alongside those efforts rather than waiting to see if lifestyle changes are enough on their own.
Blood Pressure Goals for Older Adults
If you’re over 65, the target can vary. Some guidelines for adults over 80 suggest starting medication only when systolic pressure exceeds 160, with a goal of getting below 150. The SPRINT trial, a large randomized study, found that even adults over 75 benefited from a more aggressive target of below 120 systolic, but that trial excluded people with cognitive decline, diabetes, or a history of stroke.
For most older adults, the practical approach is this: if treatment brings your blood pressure below 140 without causing side effects like dizziness, fatigue, or falls, there’s no reason to pull back. But if lower readings come with side effects that affect your quality of life or safety, a slightly higher target may be appropriate. The right goal depends on your overall health, other conditions, and how you tolerate treatment.
