Assessment and Management of Patients with Hypertension Flashcards
Most common chronic disease among U.S. adults
Hypertension
Hypertension = a systolic blood pressure (SBP) of
140 mm Hg or higher
Hypertension =a diastolic blood pressure (DBP) of
90 mm Hg or higher
To diagnose hypertension, 2 accurate blood pressure measurements must taken
1 to 4 weeks apart by a health care provider
Primary hypertension is also called
essential hypertension
In primary hypertension, 95% of patients do not have
an identifiable cause
Type of hypertension:
5% of patients; renal disease, sleep apnea, pregnancy related
Secondary hypertension
About ___% of the adult population of the U.S. has hypertension
33% or 1/3
about 1/3 of people with hypertension, do not
know they have it
About ___% do not have their hypertension under control
45-50%
In systolic BP, blood is
pushing out
In diastolic BP, the heart is
at rest
When the arteries feed the heart muscle, if the diastolic BP is too high it leads to
compromised nutrition
Genetics = __% of hypertension cases
30%
3 Determinants of high BP:
Heart rate
Stroke Volume
Peripheral vascular resistance
Amount of blood pumped out of the ventricles on each beat
Stroke Volume
The resistance in the circulatory system that is used to create blood pressure
Peripheral vascular resistance (PVR)
BP =
HR x SV x PVR
Usual symptoms other than elevated BP
None
BP symptoms related to organ damage are seen
late and are serious
BP symptoms related to organ damage:
Retinal and other eye changes
Renal damage
Myocardial infarction
Cardiac hypertrophy
Stroke
Angina
SOB
Alteration in speech or balance
Temporary block of blood flow through coronary arteries when under stress
Angina
Who is sometimes more helpful in identifying symptoms of high BP?
Patient’s partner
Controlled or stable angina means
patient knows what sets it off
A major Risk Factors of hypertension
Microalbuminuria or GFR <60 mL/min
Age when most people are diagnosed
Men 45
Women 55
Optometrist knows if a patient has hypertension when
He sees broken vessels in eye
Tests that confirm hypertension
Urinalysis (hyperalbuminemia)
Blood chemistry (bun and creatinine)
ECG
Uncontrolled hypertension can cause damage to what parts of the body?
Brain= stroke
kidneys= failure
eyes= retinal damage
heart= MI, PVD
Medical Management:
For adults, maintain blood pressure at
<140/90 mm Hg
Medical Management:
For older adult patients, maintain BP at
<150/90 mm Hg
Pharmacologic therapy used for hypertension is the same for
Heart failure
Aim of pharmacologic therapy
Decrease peripheral resistance, blood volume
Decrease strength and rate of myocardial contraction
DASH diet should be followed at least
5 days a week
Alcohol consumption per day should be
1 or less for women/ light weight
2 or less for men
Stage I hypertension med for AA and patient’s >60 yrs old
Calcium channel blocker or thiazide diuretic
Stage I hypertension med for non-AA and patients <60 yrs old
ACE inhibitors or ARB’s
What population has 3x higher risk of angioedema and more cough attributed to ACE Inhibitors?
African Americans and Asians
SBP 140-160 mmHg or DBP 90-100 is
Stage I hypertension
SBP 160+ mmHg or DBP 100 mmHg is
Stage II hypertension
