Extremity rubor usually indicates what?
Chronic arterial insufficiency
Extremity palor usually indicates what?
vasoconstriction, anemia, or ACUTE ARTERIAL INSUFFICIENCY
cyanosis on the extremities usually indicates what
decreased O2 supply - arterial insufficiency, hypoxemia, venous stasis, arterial obstruction
NY Heart association functional classification of heart disease
Class 1: no limitations, no sx.
Class 2: slight limitations of physical activity
Class 3: Marked limitation - comfy at rest but less than ordinary activity causes sx.
Class 4: Unable to engage in any physical activity without discomfort, sx may be present even at reat
Class 5: symptoms that are atypical and can occur either at rest or exertion.
BP goal per JNC7
under 140/90 or 130/80 if CKD or DM
initial treatment for HTN (JNC 7)
- Thiazide (stage 1, 140-159/90-99)
- Drug combo (stage 2, 160+/100+)
JNC 8 recommendations for HTN
For those 60+?
For those under 60?
For those 18+ with CKD?
For those 18+ with DM?
60+: initiate tx at 150 SBP or 90 DBP, treat to les than this. A recommendation.
Under 60, initiate at 140SBP or 90DBP, treat to less than this. Grade A rec for DBP, grade E for SBP and for those 18-29.
18+ with CKD: treat at 140/90 (either), treat to less than this, grade E recommendation
18+ with DM: treat at 140/90 (either #) to less than this, grade E recommendation
JNC8 recommendations for non-black HTN tx?
For black HTN treatment (inc. DM)?
For 18+ with CKD
For non-black: one of - Thiazide, CCB, ACE/ARB –> B rec
For black: Thiazide OR CCB –> B rec (or C for DM)
CKD: ACE or ARB –> B recommendation
What to do if the drug doesn’t work?
- If goal BP not reached in one month, increase dose or add another drug
- If not reached with 2, add one more
- Use other drugs if contraindication or if more than 3 drugs are needed
Can you prescribe an ACE and an ARB together?
NO WAY JOSE
Isolated Systolic Hypertension - definition and typical patient
Systolic > 140, Diastolic less than 90
-Older man with atherosclerosis and DM, obesity, alcohol use, smoking, sedentary
Sx and complications of isolated systolic HTN
Sx: really, non. headaches?
Complications: stroke, MI, HF, kidney failure
Essential hypertension - definition and typical patient
No clear cause, 140/90 BP
more common in blacks than whites
-obesity, salt intake, smoking, alcohol, NSAIDs, metabolic syndrome, sleep apnea
S/Sx of essential HTN
Mostly asymptomatic! HA most frequent. Later HTN can show retinopathy (copper/silver wiring, exudates, hemorrhages, papillidema)
End organ damage possible with HTN
Heart: LV hypertrophy--> heart failure Brain: stroke, TIA, dementia CKD PAD Aortic dissection reinopathy nephrosclerosis (particularly in african americans)
Workup for HTN pt
Hg, UA, Serum creatanine, fasting blood glucose, lipids, serum uric acid, serum electrolytes
(Dr. S - ECG, UA, HCT, K, CBG, GFR, Lipids)
Primary aldosteronism
- cause of secondary hypertension
- adrenal hyperplasia or aldosterone producing adenoma
- risks=fam hx, hypokalemia
- s/sx: mm weakness, polyuria, nocturia
- complications: organ damage (cerebral hemorrage, MI, cardiomegaly, arrhytmia, renal insufficiency), hypokalemia, metabolic alkalosis, supression of renin
CKD
- MOST COMMON cause of secondary hypertension
- increased intravascular volume or increased renin-angiotensin-ald system activity
- risks: elderly, nephrotoxic drugs, DM, CVD, HTN, SLE
- S/sx: sleep disturbances, fatigue, anorexia, N/V
- CAUTION - Kidney failure
- Workup: GFR, albumen, creatine ratio
Renovascular disease
- renal arter stenosis or fibromuscular dysplasia
- decreased renal perfusion pressure, excess renin release
- complications: end-stage renal disease, pulmonary edema, unstable cornary syndromes
Coarction of the aorta:
congenital localized narrowing of the aortic arch just distal to the left subclavian artery. Collateral circulation develops.
RADIAL FEMORAL DELAY.
Cardiac failure usually occurs in infancy, if not, pt is generally asymptomatic until HTN produces LV failure or cerebral hemorrhage.
Continuous murmur on back and left anterior chest.
Pheochromocytoma
Rare - catecholamine producing tumor within adrenal medulla, causes vasoconstriction and leads to a reduction in plasma volume.
- Postural hypotension
- Risks: TCAs, antidopaminergic agents can cause hypertensive crisis.
- S/sx: orthostatic drop of 20/10 mmHg, TRIAD of headachee, sweating, palpitations, glucose intolerance.
- SCREEN those at risk via genetics
Drug induced hypertension
Drugs that can exacerbate HTN, usually due to renal vasocontriction or sodium retention
(nsaids, cocaine, erythropoeitin, stimulants, OCPs, cyclosporine, alcohol).
Thyroid/Parathyroid
familial, acquired, autoimmune.
END ORGAN: CHF, exaggeated with levothyroxine tx.
s/sx - forceful heartbeat, PACs, sinus tac, exertional dyspnea, afib (hyper)
weakness, fatigue, cold intolerance, depression (hypo)
-TSH/T4/T3 echo
Sleep apnea and HTN
Elevated sympathetic activity, CV variability, intrathoracic pressure changes, inflammation, oxidative stress.
PT: male, older age, increased BMI/neck girth, snoring, pauses
CPAP!
complications - CV disease, AAA, HTN, DM
Hypertensive urgency vs. hypertensive emergency
Urgency: 220/125 (either one) usually does not requre emergency therapy unless organ damage is evidence. Reduce within a few hours.
Emergency: BP diastolic >130. Reduce within an hour. HOSPATILIZE! encelopathy, neuropathy, intracranial hemorrhage, aortic dissection, preeclampsia, pulmonary edema, agina, MI.
- Reduce BP by 25% within minutes to hour, then the next goal is less than 160/110 in 2-6h. Don’t drop too quickly.
- use nitroprusside, NG, lalbetalol
malignant hypertension
HTN much like hypertensive emergency–NEEDS HOSPITALIZATION, encephalopathy or neuropathy with accompanying papilledema in addition to htn
Hypercholesterolemia
Reduce saturated fats, cholesterol, increase fiber, lose weight, exercise. Treat with statins for total cholesterol <200mg/dL
Elevated LDL
-diet & lifestyle change, weight loss, quit smoking.
tx goals:
high risk, is >100, treat to less than 100
mod high, goal=130, start tx at 130
mod, goal=130, start tx at 160, lifestyle changes 130
low=less than 160, consider drug therapy at 190
hypertriglyceridemia
can be caused by obesity, DM, alcohol, CKD, COPs, diuretics. Diet is primary therapy. Statin, fibrates
low HDL
reach LDL first, focus on weight and exercise.
