Is 100/89 Good Blood Pressure or High Blood Pressure?

100/89 Blood Pressure

Is 100/89 Good Blood Pressure or High Blood Pressure?

There are two parts or two separate numbers referred to as blood pressure: Systolic/Diastolic. If the blood pressure is 100/89 (100 over 89), it means that the systolic pressure is 100 and the diastolic pressure is 89.

100/89 blood pressure can also be read as 100/89 mm Hg, or 100/89 millimeters of mercury. The 100 mm Hg Systolic refers to the pressure in the arteries when the heart beats, and the 89 mm Hg Diastolic is the pressure in the arteries between heartbeats.

When determining if 100/89 is a good blood pressure, we looked at the American Heart Association's blood pressure chart below.

Normal Blood Pressure
Systolic: Less than 120
Diastolic: Less than 80

Prehypertension Blood Pressure
Systolic: From 120 to 139
Diastolic: From 80 to 89

High Blood Pressure (Hypertension) Stage 1
Systolic: From 140 to 159
Diastolic: From 90 to 99

High Blood Pressure (Hypertension) Stage 2
Systolic: 160 or higher
Diastolic: 100 or higher

Hypertensive Crisis (Emergency care needed)
Systolic: Higher than 180
Diastolic: Higher than 110

For 100/89 to be good, both numbers must fit into the "normal" category above. Otherwise, it will fall into other categories of High Blood Pressure.

Systolic reading of 100 is in the Normal range. Diastolic reading of 89 is in the Prehypertension range.

Therefore, 100/89 is not good blood pressure (Prehypertension).

The illustration below gives a visual representation of the blood pressure 100/89 so you can better understand what it means and where it falls on the blood pressure chart.

When looking at the 100/89 BP illustration above, remember that both the Systolic pressure (blue pin) and the Diastolic pressure (purple pin) need to be in the "green zone" for 100/89 to be good and normal. As you can see, that is not the case here.
