Grade 4 Hypertensive Retinopathy
What are 2 components of a neck exam needed to evaluate for HTN?
- Thyroid (secondary HTN)
- Carotids
2 concerning respiratory PE findings for HTN
- Rhonchi
- Rales
3 concerning abdominal PE findings for HTN
- Renal masses
- Renal bruits
- Femoral pulses
3 concerning Neuro PE findings for HTN
- Visual disturbance
- Focal weakness
- Confusion
Which 2 pulses should you palpate simultaneously when evaluating a patient who may have HTN?
- Brachial
- Femoral
- Displaced PMI
- ECG evidence
FIndings for what?
Left Ventricular Hypertrophy (HTN)
What murmur will you hear in patient w/ HTN?
S4 (presystolic gallop) due to decreased compliance of left ventricle
What 3 arteries do you need to auscultate for bruits when evaluating pt w/ HTN?
- Carotid
- Abdominal (aorta)
- Femoral
What are the screening recommendations for HTN by the USPSTF?
All adults 18+
- 18 - 39 y/o (every 3 - 5 years), w/ normal BP and no risk factors
- 40+ y/o (annually)
- At increased risk for HTN (annually)
What is required for diagnosis of HTN?
- How many readings?
- How many office visits?
Based on the average of:
- 2 (or more) properly measured, seated, BP readings
- on each of 2 (or more) office visits
SBP: <120
and
DBP: <80
Normal BP
(2017 ACC/AHA guidelines)
SBP: 120 - 129
and
DBP: <80
Elevated BP
(2017 ACC/AHA guidelines)
SBP: 130 - 139
or
DBP: 80 - 89
Stage 1 HTN
(2017 ACC/AHA guidelines)
SBP: >140 (140 or higher)
or
DBP: >90 (90 or higher)
Stage 2 HTN
(2017 ACC / AHA guidelines)
- If a patient has BPs within more than 1 category, do we diagnose the higher or lower category?
- Ex: SBP: 130 DBP: 92
- Higher (always round up)
- Stage 2 HTN
Ex: SBP: 125 DBP: 83
Stage 1 HTN
Ex: SBP: 122 DBP: 78
Elevated BP
- 20 - 25% of Stage 1 HTN
- Pt is hypertensive only in the office
White coat HTN
- 10% of patients
- Increased cardiovascular risk
- In office, pt w/ normal BP, but most of the time has high BP at home
Masked HTN
What 6 tests should you order to evaluate for HTN?
- CBC
- TSH
- EKG
- UA
- Blood chemistries (glucose, Ca, creatnine, electrolytes, GFR)
- Lipid profile
What are 3 tests you might consider ordering to evaluate for HTN?
- Urine albumin excretion
- Echocardiogram
- Sleep study
Treatment for pt w/ normal BP
less than 120/80
(according to ACC/AHA 2017)
- Promote healthy lifestyle habits
- Reassess in 1 year
Tx for pt w/ elevated BP
120-129 / less than 80
(according to ACC / AHA 2017)
- Nonpharm therapy (lifestyle changes)
- Reasses in 3 - 6 months
Tx for Pt w/ Stage 1 HTN w/ risk under 10%
130 - 139 / 80 - 90
(according to ACC / AHA 2017)
- Nonpharm therapy (lifestyle changes)
Tx for Pt w/ Stage 1 HTN w/ risk 10% or higher
130-139 / 80-90
(according to ACC / AHA 2017)
- Nonpharm therapy (lifestyle changes)
- BP lowering medication
Tx for Pt w/ Stage 2 HTN
Over 140/90
(according to ACC / AHA 2017)
- Nonpharm therapy (lifestyle changes)
