Hypertension (HTN)
What Is Hypertension



Persistent blood pressure that is higher than the
recommended blood pressure range
About 60% of all Americans have some form
of high blood pressure (pre-hypertension or
hypertension)
HTN means the heart is working harder than
normal putting extra strain on the heart and
vessels.
Blood Pressure Ranges





Normal blood pressure range < 120/80
Pre-Hypertension >120/80 but <140/90
Hypertension - >140/90
Both systolic and diastolic pressures do not have
to be out of range
Only Systolic or Diastolic must be out of range
to qualify as hypertension
Two Stages of HTN


Stage 1 HTN >140/90 but <160/100
Stage 2 HTN >160/100
What Causes HTN



90%-95% of the time hypertension is elevated
blood pressure without an identifiable cause.
Exact cause is unknown
Many contributing factors have been identified
as predisposing factors to HTN
Predisposing Factors for HTN

Hereditary Predisposition (Family History)
Sodium intake
Weight
Diabetes Mellitus
Alcohol Consumption
Smoking
Serum Lipid Levels (Cholesterol and LDL)
Sedentary Lifestyle
Ethnicity
Age
Gender
Socioeconomic Status
Stress
Signs and Symptoms



Known as the Silent killer
If BP is very high, you may experience:
-fatigue
-decreased activity tolerance
-dizziness
-palpitations
-angina
-dyspnea
How HTN is diagnosed




Based on the average of
2+ seated BP
measurements at the
MD’s office
Must be averaged
Must be seated BP
measurements
Must be in the MD’s
office
Complications Related to HTN







Heart Failure
Enlarged Left Side of the Heart
Coronary Artery Disease
Cerebrovascular disease (Brain)
Peripheral Vascular Disease
Kidney Failure
Retinal Damage (Eyes)
Treatment of HTN






Different types require different treatments
Pre-Hypertension – Lifestyle modifications
Stage I Hypertension – Lifestyle modifications
and a thiazide-type diuretic
Stage II Hypertension – Lifestyle modifications,
thiazide-type diuretic and one another
antihypertensive drug
Not definitive
Treatment is personalized
How to Prevent HTN

Lifestyle modifications prevent HTN and include:
-Maintaining a Healthy Weight
-Reduce Salt/Sodium Intake
-Increase Physical Exercise
Smoking Cessation
Limit Alcohol Consumption
Limit Fat Intake
Control Diabetes
Stress Relieving Techniques
Take BP Meds as Ordered
Home Monitoring of BP
