Q

HTN stages?

A

< 120/80 = nl

120/80 < Pre-hypertensive < 140/90

140/90 < Stage 1 HTN < 160/100

Q

Follow up recommendations based on HTN stages?

A

nl = recheck in 2 years

Pre-HTN = recheck in 1 year & give info about lifestyle changes

Stage 1 = confirm within 2 months & give info about lifestyle changes

Stage 2 = evaluate or refer within 1 month
>180/110 = treat immediately

Q

How does caffeine effect BP?

A

If always have 1-2 cups of coffee, no effect

If suddenly spike in caffeine or take a massive amount can cause HTN

Q

Effect of weight on BP?

A

Obese people are more likley to have HTN, but just because you are fat doesnt mean you automatically have HTN

More important than absolute weight is change in weight. Sudden increase –> HTN

Q

What is Copper Wiring?

25
Severe acute HTN can cause what fundoscopic finding?
Flame shaped hemorrhage Ischemia --> white superficial focus = cotton wool spot Yellow hard exudate Optic disk edema or papiladema (swelling)
26
HTN labs?
``` CMP Lipids Glucose CBC Urinalysis ECG Echocardiogram ``` * similar to PAD workup
27
What things in general should make you suspicious that HTN may be SECONDARY to another cause?
``` < 25 yo Drug resistant (3 drugs at max dose dont work) ```
28
HTN with hypokalemia points towards what? Test?
High aldosterone/Conn's Disease (secondary HTN) Plasma aldosterone-renin ratio
29
Intermittent HTN with palpatations, sweating & headaches points towards what? Tests?
Pheochromocytoma (secondary HTN) = adrenal tumor Serum catecholamines or metanepherines, Ab CT/MRI
30
HTN with a epigastric bruits points towards what? Test?
Coarctation (secondary HTN). Aorta narrowed --> blood has to pump harder --> entire body effected Chest Film
31
HTN with renal artery bruits points towards what? Best test?
Renal artery stenosis (secondary HTN) = renovascular disease Angiography
32
Suggested lifestyle changes to lower BP?
``` Lose weight DASH diet Na reduction Physical Activity Alcohol in moderation ```
33
Who generally needs a 2 drug combination for HTN? Which drugs are these usually?
Stage 2 (think 2 for 2) Diuretic + CCB/BB/ARB/ACEI
34
Difference between HTN urgency & emergency?
Emergency has some sort of end organ damage
35
What HTN meds should not be given to pregnant patient?
ACEI | ARB (ang rec block)
36
If have edema & HTN, what is the best treatment?
Diuretic
37
If have BPH & HTN, what is the preferred treatment?
Alpha blocker (relax muscle in prostate & bladder)
38
If you have Raynaud's & HTN, what is the preferred treatment?
CCB (relax peripheral vessels cuz have less Ca for smooth muscle contraction)
39
Who should not receive diuretics?
Gout Hyponatremia Hypokalemia
40
Who should not receive beta blockers?
Asthma Reactive airway disease 2nd or 3rd degree heart block
41
Who should not receive ACEI?
Patients with history of angioedema Pregnant patient
42
Best treatment for HTN patient with diabetes?
ACEI or ARB (both processes that take place in kidney) can have renal protective effects & prevent proteinuria Same as kidney disease
43
CVD stands for?
Cardiovascular disease
44
If have proteinuria greater than 1g, you should treat HTN until BP is <125/75 according to who?
National Kidney Foundation
45
A patient with prior angioedema should not receive what drug?
ACEI
46
Somebody with gout should not receive what mediation?
Diuretic
47
Somebody with hyponatremia should not receive what drug?
Diuretic
48
Somebody with Asthma or reactive ariway disease should not receive what drug?
Beta blocker
49
Somebody with gout should not receive what drug?
Diuretic
50
What is suspected with HTN & high or low TSH?
Hypo or hyper thyroid can be related to HTN (secondary HTN)
51
What is suspected with HTN & fatigue?
Sleep apnea Hypothyroidism Both = secondary HTN
52
What is suspected with HTN, high Ca & low P? Test?
Hyperparathyroidism (secondary HTN) Serum PTH
53
What is suspected with HTN & high aldosterone?
Aldosteronism/Conn's (secondary HTN) where adrenal tumor causes the release of aldosterone with causes salt & water retention --> more blood volume
54
What is suspected with HTN & high urinary cortisol? Test?
Cushings (secondary HTN) = pituitary hormone Dexamethasone suppression test
55
How are kidney diseases and HTN related?
Limit the kidney ability to excrete fluid --> increased blood volume --> secondary HTN
