Blood Pressure - Know Your Number

You can reduce your risk of having a heart attack or stroke by keeping your blood pressure controlled, ideally to a level of 119/79 or lower.

What is hypertension?
Blood pressure is the force or pressure of blood against your artery walls. When you have high blood pressure, your heart has to work harder than it needs to send blood throughout your body. Hypertension is another word for high blood pressure.

Why is it important to know your blood pressure number?
High blood pressure usually has no symptoms. The only way you know if you have high blood pressure is to check it. It is important to know your number because having hypertension increases your chance of having a heart attack or stroke. The good news is lowering your blood pressure significantly reduces your risk of having a heart attack, stroke, and several other serious health problems.

Definitions of Blood Pressure Ranges

The top number (119/79) of your blood pressure measurement represents the systolic pressure. This is the force of blood against your arteries when your heart is sending blood to your body. The lower number (119/79) is the diastolic pressure. This is the force of blood against your arteries while your heart relaxes between beats. Both numbers are important.

Normal: 119/79 or lower
Prehypertension: 120-139/80-89
Hypertension: 140/90 or higher

For blood pressure of 120-139/80-89 lifestyle changes are a good idea to prevent or delay developing hypertension. The likelihood of high blood pressure increases as people age.
