Therapeutics of HTN pt. 1 Flashcards
what is essential htn
elevated arterial blood pressure with an unknown etiology
what is secondary htn
elevated arterial blood pressure due to concurrent medical conditions or medications
what is isolated systolic htn
systolic BP values are elevated and diastolic BP values are not
what is resistant htn
failure to attain BP goal while adherent to a regimen that includes at least 3 agents at max dose (including a diuretic) or when 4 or more agents are needed
what is orthostatic hypotension
a systolic BP decrease of >20 mmHg, a diastolic BP decrease of >10 mmHg within three minutes of positional change, and/or increase in HR >20 bpm
what are essential htn pathophysiology
humoral abnormalities
neuronal mechanisms
vascular endothelial mechanisms
peripheral autoregulation defects
electrolyte disturbances
what are the modifiable htn risk factors
high sodium intake
obesity
low potassium intake
excess alcohol intake
what are the non-modifiable htn risk factors
age
ethnicity
genetic predisposition
gender
what can cause secondary htn
CKD
renovascular disease
primary aldosteronism
OSA
drug-induced
food/substances
pheochromocytoma
cushing’s syndrome/chronic steroid use
thyroid or parathyroid disease
aortic coarctation
what substances can increase BP
illicit drugs
caffeine
nicotine
decongestants
amphetamines
antidepressants
atypical antipsychotics
immunosuppressants
OCs
NSAIDs
systemic steroids
oncology agents
what is the in office BP measurement
two readings, 5 minutes apart, and sitting in a chair. take measurement in opposite arm to confirm reading
what is ambulatory BP monitoring indicated for
indicated for white coat, masked htn, nighttime BP dipping
what is home BP monitoring indicated for
indicated for evaluation of white coat, masked htn, and response to therapy
what is normotensive BP pattern
no htn in healthcare setting
no htn in home/AMB setting
what is sustained htn BP pattern
htn in healthcare setting
htn in home/AMB setting
what is masked htn pattern
no htn in healthcare setting
htn in home/AMB setting
what is white coat htn pattern
htn in healthcare setting
no htn in home/AMB setting
what are the pros of HBPM and ABPM
confirm diagnosis
aide in med titration
identify white coat and masked htn
better predictor of long term cv outcomes
what are the cons of HBPM and ABPM considerations
user error
equipment cost
will insurance cover?
what is normal BP
<120 AND <80
