25
When is HTN more common for men
before 45
26
When is HTN more common for women
after 64, estrogen levels
27
Is HTN a side effect of oral contraceptives
There is a higher risk
28
Who have the poorest BP control
women 70-79
29
What is secondary HTN
From identifiable cause, treat cause
30
What is malignant HTN
Rapid, diastolic >120, potential STROKE
31
What are some lifestyle changes to treat HTN
sodium restriction diet (DASH): 2g per day
32
What are the medicaiton options for HTN
RAAS or direct vasodilators
33
What are the meds that are active with RAAS
ACE-I, ARB, deirect renin inhibitors, aldosterone antagonists
34
What does the RAAS system do
Regulate BP, blood volume, fluid and electrolyte balance
35
Explain the RAAS system
Liver secretes angiotensinogen, when BP or volume drops renin is releseased from the kidneys, creates angiotension I (ACE-I), ACE releases from lungs to form angiotensi II, That releases aldosterone and constricts vasoconstriction
36
How do ACE-I work
Reduce levels of angiotension II
37
What are the adverse effects of ACE-I
dry nonproductive cough, hyperkalemia, renal failure, angioedema (AIRWAY), fetal injury
38
What do ACE-I end in
PRIL
39
What is the ACE-I drug to know
Lisinopril
40
What do ARBs do
Block access of angiotensin II to receptors in blood vessels, cause DILATION, reduce excretion of potassium, prevents changes in STRUCTURE (heart failure)
41
What do ARBs end in
SARTAN
42
What is the ARB drug to know
Losartan
43
What do direct renin inhibitors (DRIs) do
Directly effect, binds to renin
44
What are the things to do with DRIs
Avoid high fats
45
What is an example of aldosterone antagonists
Sporlactions
46
What are aldosterone antagonists used to treat
HYpertension and heart failure
47
What do aldosterone antagonist do
BLock receptros for aldosterone, promote retention of potassoim and excretion of water
48
What should you know about spironlactone
Affects hormones
49
What about eplerenone
Less effects
50
Can you have more than 1 RAAS med
NO
51
What do vasodilators do
Reduce resistance and workload, dialates CORONARY vessels
52
What are the adverse effects of vasodilators
Hypotension, reflex tachycardia, HEADACHE
53
What is hydralazine used ofr
HTN, it is an arterial dilator
54
What are the dise effects of hydralazine
Headache
55
What other meds should you have when using hydralazine
Beta blockers to prevent reflex tachycardia, and diuretics to prevent water retention
56
What is sodium nitropusside used for
FAST-acting, IV infusion
57
What is the major side effect of sodium nitroprusside
Excressive hypotension, MONITOR
58
What symtpoms occur with H?TN
NOTHING
59
What meds end with pril
ACE-I
60
What meds end with sartan
ARBs
61
What is heart failure
Blood is not getting out
62
What is heart failure (four)
Ventriclular dysfunction, reduced cardiac output, insufficient trissue perfusion, fluid retention
63
What are the syptoms of heart failre
Edema, tachycardia, increased heart size, oliguria
64
What can cause herat failure
Uncontrolled BP, increase after/pre load, lose of elasticity
65
What are some of the risk factors for heart failure
MI, obesity, smoking, diabetes
66
Which drugs prevent structural changes
ARBs
67
What are the physologic changes of heart failure
Decrease cardiac output, less GFR, less PEE, stims RAAS system, VASOCONSTRICTION, WATER retention
68
What are natriuratic peptides and what do they do
ANP and BNP, released with stretching of the artria, promote loss of fluid
69
What does BNP meausre
Cardiac statue in heart failure pts
70
If you can get fluid off then BNP should
Be better, <100
71
What does heart failure lok like
Where the fluid stays
72
What are the S+S of left sided failure
LUNGS: cynosis, pulmonary issures, sweating, tachycardia, confusion
73
What are the S+S of right sided failure
BODY: edema in body, JVD, fatigue
