Blood Pressure: Key to Heart Health

High-Blood-pressureYour doctor tells you your blood pressure numbers, or you hear the doctors on ER shout “pressure’s dropping!” Do you actually know what that means?

Blood pressure consists of two numbers. Your systolic pressure measures the pressure of blood against artery walls when the heart pumps blood out during a heartbeat, while the diastolic pressure measures the same pressure between heartbeats, when the heart fills with blood. “Both of these numbers are important, just because one is normal doesn’t mean you’re off the hook.”

Normal blood pressure is below 120/80.

Pre-hypertension is 120 to 139 (systolic) and/or 80 to 89 (diastolic).

Hypertension – also known as high blood pressure — is 140 or higher (systolic) and 90 or higher (diastolic).

One in three adults in the U.S. — about 74 million people — has high blood pressure or pre-hypertension. Between 1996 and 2006, the number of deaths from high blood pressure rose by more than 48%.
