•
– Pressure created by the heart as it pumps blood through the arteries and the circulatory system
•
– Top number (Systolic)= Pressure while heart is beating
– Bottom number (Diastolic)= Pressure while heart is resting between beats

•
– Blood Pressure of < 140/ 90
– Blood Pressure of 130 to 139/ 85 to 89 should be closely watched
•

• What Causes High Blood
Pressure?
– Cause unknown in 90 to 95% of cases =
Primary Hypertension
– Secondary Hypertension = 5 to 10%
• Kidney Abnormalities
• Narrowing of certain arteries
• Rare tumors
• Adrenal gland abnormalities
• Pregnancy

• What Causes High Blood
Pressure?
– Uncontrollable Risk Factors
• Heredity
• Age
– Men between age 35 and 50
– Women after menopause
• Race
– 1 out of every 3 African Americans
– Higher incidence in non-Hispanic blacks and
Mexican Americans

• Women and High Blood Pressure
– Birth Control Pill
– Pregnancy
– Overweight
– After Menopause
– African Americans
Hypertension

•
– Certain nerve impulses cause arteries to become larger (dilate) or smaller (contract)
– If vessels wide open blood flows easily
– If vessel narrows pressure inside increases causing hypertension

•
– Stroke
– Congestive heart failure
– Kidney failure
– Heart attack
– Heart rhythm problems
– Aneurysm

• What Can I Do?
– High blood pressure is a lifelong disease
– Blood pressure can be controlled not cured
– Controlling blood pressure will reduce the risk of stroke, heart attack, heart failure and kidney disease

• Medication for High Blood
Pressure
– Diuretics
• Rid the body of excess fluids and salt
– Beta-blockers
• Reduce the heart rate and the work of the heart
– Calcium antagonists
• Reduce heart rate and relax blood vessels
Hypertension

• Medication for High Blood
Pressure
– Angiotensin II receptor blockers(ACE)
• Interfere with the bodies production of angiotensin, a chemical that causes the arteries to constrict (narrow)
– Vasodialators
• Cause the muscle in the wall of the blood vessels to relax, allowing the vessel to dialate (widen)
Hypertension
Lifestyles, Fitness and Rehabilitation
• Medication for High Blood
Pressure
– Sympathetic nerve inhibitors
• Sympathetic nerves go from the brain to all parts of the body, including the arteries
• Cause arteries to constrict raising blood pressure
• These drugs reduce blood pressure by inhibiting these nerves from constricting blood vessels
