Hypertension

Hypertension

• What is Blood Pressure?– Pressure created by the heart as it pumps

blood through the arteries and the circulatory system

• What do Blood Pressure Numbers Mean?– Top number (Systolic)= Pressure while heart is

beating– Bottom number (Diastolic)= Pressure while

heart is resting between beats

Hypertension

• Normal Blood Pressure– Blood Pressure of < 140/ 90– Blood Pressure of 130 to 139/ 85 to 89 should

be closely watched

• High Blood Pressure– Blood Pressure > 140/ 90


Hypertension

• How can I tell if I have High Blood Pressure?– Usually NO SYMPTOMS!– “The Silent Killer”–May have: • Headache• Blurry vision• Chest Pain• Frequent urination at night


Hypertension

• Blood Pressure Measurement– Sphygmomanometer– Systolic pressure= pressure when 1st sound is

heard– “Diastolic pressure= pressure when last sound

is heard

• Blood Pressure Cuff Size– Small – children and small adults– Average– Large – overweight and large adults

Hypertension

• 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


Hypertension

• What Causes High Blood Pressure?– Controllable Risk Factors• Increased salt intake• Obesity• Alcohol• Stress• Lack of exercise


Hypertension

• 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


Hypertension

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


Hypertension

• How does High Blood Pressure develop?– 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


Hypertension

• What does High Blood Pressure do to my Body?– Stroke– Congestive heart failure– Kidney failure– Heart attack– Heart rhythm problems– Aneurysm


Hypertension

• 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


Hypertension

• What Can I Do?– Loose weight if your overweight– Get regular physical activity– Avoid excessive alcohol– Stop smoking–Manage your stress


Hypertension

• What Can I Do?– Decrease salt intake– Eat for heart health– Discuss the use of oral contraceptives

with your doctor– Discuss the use of some medications

with your doctor


Hypertension

• Ten Commandments for Blood Pressure Control– Know your blood pressure• Have it checked regularly

– Know what your weight should be• Keep it at that level or below

– Don’t use excessive salt in cooking or at meals• Avoid salty foods

Hypertension

• 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

• 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


Hypertension

• Home Blood Pressure Monitoring–Mercury sphygmomanometer• Standard for BP monitoring• No calibration• May be bulky• Need a second person to use machine• May be difficult for hearing impaired or

patients with arthritis


Hypertension

• Home Blood Pressure Monitoring– Aneroid equipment• Inexpensive, lightweight and portable• Two person operation/need stethoscope• Delicate mechanism, easily damaged• Needs calibration with mercury

sphygmomanometer


Hypertension

• Home Blood Pressure Monitoring– Automatic equipment• Contained in one unit• Portable with easy-to-read digital display• Expensive, fragile• Must be calibrated• Requires careful cuff placement
