1
Q

to diagnose hypertension

A

need TWO readings

2
Q

essential HTN

A

no known cause - idiopathic

3
Q

most likely cause of HTN

A

essential - no known cause

4
Q

risk factors for essential HTN

A
obesity
high salt diet
hereditary
alcohol
age
5
Q

headaches and HTN

A

don’t treat to solve headache

6
Q

HTN risk of what conditions

A
stroke
MI
heart failure
ESRD
aortic dissection
PVD
7
Q

HTN in young**

A

increased peripheral vascular disease (vasospasm)

  • level of small arterioles
  • both systolic and diastolic elevated
8
Q

HTN in old**

A

aorta stiff - collagen replaces elastin

-isolated systolic HTN**

9
Q

recommended life-style modifications for patient

A

minimum 30 minutes most days of week
-HR elevation 70% (220-age)

DASH diet - fruit, veggies, low fat

moderation of alcohol - less than 2/day or 10/week

10
Q

treat with drugs or wait for lifestyle mods?

A

drug.

11
Q

intitial HTN med for non-black

A

ACE (-)
ARB
CCB
thiazide diuretics

12
Q

initial HTN med for black

A

CCB

thiazide diuretics

13
Q

cushings

A
  • adrenal overactivity
  • striae - fast weight gain
  • cause of HTN
14
Q

dexamethasone suppression test

A

cushing test

15
Q

secondary HTN

A
  • hard to control HTN
  • compelling ginding
  • atypical age
  • absence of predisposing factors
16
Q

renal artery stenosis

A

cause of secondary HTN

17
Q

Dx for renovascular HTN

A
captopril
DSA
MRI - angiography
arteriography
renal vein renin ration
18
Q

captopril

A

rise in renin and large fall in BP after administration

captopril - ACE (-)

  • abnormal test - renovascular disease
  • diagnosis - renal artery stenosis
19
Q

two main causes of renal artery stenosis

A
  • atherosclerosis

- fibromuscular dysplasia

20
Q

careful with these meds with renal a. stenosis

A

ACE (-)

unilateral - BP falls
bilateral - unpredictable, may worsen HTN
one kidney - unpredicatble, may worsen HTN

21
Q

fibromuscular dysplasia

A

young females
bilateral renal a stenosis
responds to angioplasty

22
Q

atherosclerosis

A

older males

unilateral renal a stenosis

23
Q

test for hyperthyroid

A

TSH

24
Q

black with hyperthyroid meds for HTN

A

beta-blocker

  • non-selective
  • propanolol
25
Q

HTN with low K

A

hyperaldosteronism

hypokalemia is the clue**

26
Q

hypertensive urgency

A

systolic > 180
diastolic > 130
NO evidence of organ damage

27
Q

hypertensive emergency

A

any BP - includes end organ damage

28
Q

secondary hyperaldosteronism

A
diuretics
CHF
cirrhosis
ascites
nephrosis
etc
29
Q

weak with hyperaldosteronism?

A

hypokalemia - muscle weakness

30
Q

Tx for hyperaldosterone HTN

A

spironolactone

-aldosterone blocker**

31
Q

adrenal conditions with 2nd HTN

A

cushings
hyperaldosteronism
pheochromocytoma

32
Q

test for pheochromocytoma

A

VMA levels

33
Q

coarctation of aorta

A

difference in BP arms to legs
-20mmHg

also - systolic ejection murmur

can cause secondary HTN

narrowing medial layer of aorta

  • commonly at ligamentum arteriosum
  • interrupted, preductal, postductal
