Hypertension Flashcards
Long term HTN consequences
-left ventricular hypertrophy
-angina/MI
-coronary revascularization
-HF
-stroke/TIA
-CKD
-PVD
-Retinopathy
essential HTN
-elevated arterial blood pressure
secondary HTN
-elevated arterial BP due to med conditions or meds
Isolated systolic HTN
-only systolic BP elevated
Resistant HTN
-failt to attain goal BP on regimen of 3 agents at max dose (including diuretic)
-or when 4 or more agents needed
Orthostatic HYPOtension
-systolic BP dec of > 20 mmHg
-diastolic BP dec >10 in 3 min of position change
-and/or inc in HR > 20 bpm
Essential HTN patho
-humoral abnormalities
-neuronal mechs
-vascular endothelial mechs
-peripheral autoregulation defects
-electrolyte disturbances
BP =
CO * TPR
CO =
SV * HR
modifiable HTN risk factors-
-high sodium intake
-obesity
-low potassium intake
-excess alcohol
Non-modifiable risk factors HTN
-age
-race
-genes
-gender (female more under 64 esp under 55)
Secondary HTN causes
-CKD
-renovasc disease
-primary aldosteronism
-obstructive sleep apnea
-drugs
-foods
-pheochromocytoma
-cushing’s/chronic steroid use
-thyroid or parathyroid disease
-aortic coarctation
Substance that can INC BP
-drugs
-caffeine
-nicotine
-decongestants
-amphetamines
-antideppressants
-antipsychotics (-zapines)
-immunosuppressants (cyclosporine)
-contraceptives
-NSAIDs
-systemic steroids
-oncology agents
BP measurement techniques
-in-office
-ambulatory BP monitoring (ABPM)
-home BP monitoring
Normotensive
no HTN in office or at home
sustained HTN
-HTN in office and at home
masked HTN
-no HTN in office
-HTN at home
white coat HTN
-HTN in office
-no HTN at home
HBPM and ABPM considerations
-confirm diagnosis
-aid in med titration
-identify white coat and masked HTN
-better predictor of long term outcomes
-user error
-cost/insurance
Normal BP
<120/<80
Elevated BP
120-129/<80
HTN stage 1
130-139 or/80-89
HTN stage 2
> 140/ or >190
Normal BP strategies
-promote healthy lifestyle
-comeback in 1 year
Elevated BP strategies
-non-pharma
-reasses 3-6 months
Stage 1 HTN strategies
-IF ASCVD risk > 10% or comorbidity, non pharm and meds reassess 1 month
-IF NOT, nonpharma reassess 3-6 months
Stage 2 HTN strategy
-nonpharma + 2 meds
-reassess one month
HTN patients at goal should follow up ehen
-every 3-6 months
BP thresholds for tx
->140/90 for no clinical CVD and <10% ASCVD risk or secondary stroke prevention
BP goals
-<130/80
-140/90 okay in elderly frail pt w high comorbidity burden and limited life expectancy
-<120 with CKD if tolerated
trials?
Nonpharma tx
-weight loss
-DASH diet**
-dec sodium intake
-inc potassium
-physical activity
-mod alcohol intake
DASH diet
-fruits and veggies
-whole grains
-fat-free/low fat
-fish, poultry, beans
-nuts/vegetable oils
-potassium, ca, mg, fiber, protein
-limit saturated fats and sweets
Pharma tx options
-Angiotensin-converting enzyme (ACEi)
-Angiotension receptor blockers (ARBs)
-Calcium Channel Blockers (CCB)
-direct renin inhibitors
-beta blockers
-diuretics
-alpha 1 blockers
-central a2 agonists
-vasodilators
