HTN Flashcards
How is HTN linked to functional decline
End organ damage such as renal function and vascular dementia. #1 cause of strokes, possible like to Alzheimers
Is there benifit to tx in people over 80yrs old
Yes, trial showl large reduction of death rate from stroke (39%), CVD (23%), HF (64%), other causes (21%).
Which vessels are resistant in systolic HTN
Large vessels
Which vessels are resistant in dystolic HTN
small vessels with HTN leading to increased resistance and even closure of small vessels
Lifestyle factors associated with HTN
Smoling, excessive ETOH, obesity
Definition of HTN (stage 1)
BP 140/90 x 3 readings
Definition of essential HTN
HTN without known cause eg environmental and genetic combination
Defefnition of secondary HTN
eg renal disease, hyperthyroid disease
pseudoHTN
brachial stiffness so that cuff cannot compress and get a correct reading
HTN hypterensive urgency
Systolic of 179 or diastolic 109 - no symptoms of end organ damange. Emergency if symptomatic IE: SOB, chestpain, headahce, visual changes, acute renal failure, altered mental status
What is appropriate cuff size
80% of upper arm circumference
Should people <90 be treated for HTN
Evidence does not support at this time
What systolic BP should be treated in <80 yrs old
< 150mmHg to target 140 - 145mmHg
Non-pharm tx
weightloss, activity, DASH diet, d/c smoking, reduce etoh
Definition of HTN (stage 2)
SBP - 160, DBP - 100
