Blood Pressure
► Blood
Pressure (BP): The pressure exerted
on the walls of the arteries as blood passes
through via contraction of the heart
 Systolic BP: The pressure exerted on the walls
of the arteries during the contraction phase of
the heart (Normally 120 mmHg)
 Diastolic BP: The pressure exerted on the walls
of the arteries during the relaxation phase of
the heart (Normally 80 mmHg)
Measuring Blood Pressure
Hypertension
► Definition:
pressure.
Persistently high arterial blood
 Systolic blood pressure ≥ 140 mmHg
 Diastolic blood pressure ≥ 90 mmHg
► United
States Statistics:
 65,000,000 hypertensive in U.S.
►22%
of US population
 1 in 3 (~33%) US adults
► Why
do we care?
 Hypertension is the most prominent risk factor
in most all cardiovascular diseases (CVD)
CVD Associated with Hypertension:
Atherosclerosis
CVD Associated with Hypertension:
Heart Disease
