A blood pressure of 117/73 mmHg is a good reading. It falls squarely in the “normal” category under the latest guidelines from the American Heart Association and the American College of Cardiology, which define normal blood pressure as below 120/80 mmHg. Both your top number (systolic) and bottom number (diastolic) are comfortably within the healthy range.
What 117/73 Means for Your Heart
The two numbers in a blood pressure reading measure different things. The top number, 117, reflects the pressure your blood exerts against artery walls each time your heart beats. The bottom number, 73, measures that same pressure between beats, when your heart is briefly at rest. Together, they paint a picture of how hard your cardiovascular system is working to move blood through your body.
At 117/73, your heart is pumping efficiently without placing excessive force on your artery walls. This matters because sustained high pressure damages arteries over time, increasing the risk of heart attack and stroke. Keeping both numbers below the 120/80 threshold is associated with the lowest cardiovascular risk.
How Close Is 117/73 to the Danger Zone?
Your reading sits just 3 points below the systolic cutoff where blood pressure stops being “normal” and enters the “elevated” category (120 to 129 systolic with diastolic still under 80). That’s a small margin, but it’s still on the right side of the line. Here’s how the full classification breaks 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
These categories apply to all adults regardless of age. Earlier guidelines used to allow higher targets for older adults, but current standards treat the thresholds the same whether you’re 30 or 70.
One Reading vs. Your Actual Blood Pressure
A single reading is a snapshot, not a diagnosis. Blood pressure fluctuates throughout the day based on stress, caffeine, physical activity, hydration, and even the time of day. If you took this reading at a pharmacy kiosk or with a home monitor, it’s useful information, but your “true” blood pressure is the average across multiple readings taken at different times.
For the most accurate picture, measure at the same time of day, sitting quietly for five minutes beforehand, with your arm supported at heart level. Two or three readings a few minutes apart, averaged together, will give you a number you can rely on. If those averages consistently land near 117/73, you’re in great shape.
Keeping Your Blood Pressure in the Normal Range
Having normal blood pressure now doesn’t guarantee it stays that way. Blood pressure tends to creep upward with age as arteries gradually stiffen. The habits that matter most for keeping your numbers where they are come down to a few basics.
Aim for at least 30 minutes of moderate physical activity most days. Walking, cycling, swimming, or anything that gets your heart rate up consistently is enough. On the dietary side, sodium intake plays a direct role. Keeping sodium below 2,300 mg per day is a reasonable target, though closer to 1,500 mg per day is ideal for most adults. That means watching processed foods, restaurant meals, and packaged snacks, which account for the majority of sodium in most people’s diets.
Maintaining a healthy weight, limiting alcohol, managing stress, and not smoking all contribute as well. None of this is groundbreaking advice, but it’s the difference between staying at 117/73 in your 50s and drifting into the elevated or Stage 1 range where lifestyle changes become corrective rather than preventive.
