Hypertension Flashcards
most important cause of secondary hypertension
renal disease
drugs that increase BP
amphetamines/ADHD drugs
cocaine
decongestants (pseudoephedrine/phenylephrine)
erythropoiesis-stimulating agents
immunosuppressants (cyclosporine)
NSAIDs
systemic steroids
excessive alcohol
appetite suppressants (phentermine)
caffeine
herbals (ma huang, licorice, yohimbine)
oral contraceptives
select oncology drugs (bevacizumab, TKIs)
antidepressants (TCAs, SNRIs, MAOis)
BP monitoring Dos
go to restroom/empty bladder
sit in chair; both feed on floor; relax for 5 or more minutes
use correct cuff size
support arm and heart level
wait 1-2 min between readings
average 2 or more readings on two separate times in day
BP monitoring Don’ts
talk
sit/lie down on examination table
drink caffeine, exercise, or smoke for 30 minutes before
use finger/writ monitor (less accurate)
is self-monitoring or physician monitoring of BP preferred?
self
ACC/AHA categories of BP in results
normal: SBP >120 and DBP <80
Stage 1 hypertension: SBP 130-139 or DBP 80-89
Stage 2 hypertension: SBP >=140 or DBP >=90
lifestyle management
weight loss
diet (DASH)
dec sodium <1500
tobacco cessation
natural products
fish oil
coenzyme Q10
L-glargine
garlic
treatment principles (ACC/AHA)
emphasize lifestyle
once-daily preferred for med adherence
preferred for initial and/or titration of treatment: ACEI, ARBs, DHP CCBs, thiazide diuretics (not ACEI/ARBs together)
when to start treatment
Stage 2 HTN
Stage 1 HTN and clinical CVD (stroke, HF, CAD); 10-year ASCVD risk >=10%; or does not meet BP goal after 6 months of lifestyle modifications
BP goal
<130/80
initial drug selection
non-black: thiazide, DHP CCB, ACEI/ARB
black: thiazide or DHP CCB
CKD: ACEI/ARB (for renal benefit)
diabetes w/ albuminuria: ACEI/ARB
diabetes w/ CAD: ACEI/ARB
start 2 first-line drugs in Stage 2 HTN when average SBP and DBP >20/10 above goal
monitoring for hypertension guidelines
monitor every month and titrate meds if not at goal
pregnancy and HTN
ACEIs, ARBs, and aliskiren (direct renin inhibitor): BBW for fetal toxicity; stop immediately
preeclampsia: after 20 weeks of pregnancy; elevated BP and proteinuria
if chronic HTN and BP >=160/105 = give drug treatment - labetalol and nifedipine ER recommended; methyldopa recommended but maybe less effective
thiazide diuretics MOA
inhibit sodium reabsorption in DCT = excrete sodium, Cl-, water, K+
