Q

Neuro-hormonal mechanisms and compensatory mechanisms in HF?

A
  • poor ventricular fxn/myocardial damage (post MI, dilated cardiomyopathy) -
  • leads to HF - this leads to decreased stroke volume and CO - this leads to neurohormonal response - this leads to activation of sympathetic sytem and RAAS - vasoconstriction, and sodium and fluid retention - increased vasopressin and aldosterone - this leads to further stress on ventricular wall and dilation (remodeling) - leads to worsening of ventricular fn - further HF

Q

3 stages of diastole?

A
  • isovolemic (active) relaxation and rapid early filling (reqr ATP)
  • diastasis (passive) filling: - dictated by how compliant the ventricle is, there is slowed LV relaxation and rise in LV diastolic pressure, stage worsens w/ age
  • active filling during atrial contraction, dependent on LV diastolic pressure
  • all phases affected by preload, afterload, HR and contractility: systolic flow greater than diastolic flow until diastolic dysfxn due to stiff ventricle and decreased atrial emptying

27
Q

General management of HF?

A
  • stabilize pt w/ diuretic
  • stabilize disease: ACEI + BB
  • can also use digoxin to tx residual sxs if needed
28
Q

Guidelines for diuretics use?

A
  1. diuretics: used in sx pts to reduce fluid, no survival benefit
  2. increase initial dose as necessary to relieve congestion. After effective diuretic is achieved w/ short acting loop diuretics, increasing admin to 2-3x a day may provide more diuresis w/ less physiologic upset than a larger single dose
  3. torsemide and bumetanide which have higher bioavailability can be effective in pts w/ por absorption of oral meds or erratic diuretic effect, esp in right sided HF and refractory retention despite high doses of other loop diuretics
  4. IV diuretics may be necessray to relieve congestion
  5. add chlorthiadone or metolazone when high dose loop diuretic not effective - avoid chronic use
  6. selected pts may be educated to adjust daily dose of diuretic in response to wt gain from fluid overload
  7. diuretic refractoriness may represent pt non-adherence, a direct effect of diuretic use on kidney or profession of underlying cardiac dysfxn
  8. observe for SEs including electrolyte abnormalities, sx hypotension, renal dysfxn, or worsening renal fxn
29
Q

Use of ACEIs? Examples?

A

  • improves cardiac fxn, sxs, and clinical status
  • all pts w/ LVEF less than 40% should receive an ACEI, ARBs used when intolerant of ACEI (Diovan, Atacand, losartan) for reasons other than hyperkalemia, renal insufficiency
30
Q

CIs of ACEI/ARBs?

A
  • hx of intolerance, CI in pregnancy
  • serum K+ greater than 5 mEq/L
  • sx hypotension: asx SBP less than 80 or sx orthostatic BP when pt is euvolemic
  • caution in pts w/ Cr over 3.0 mg/dL
31
Q

Surveillance for pts on ACEI/ARBs?

A
  • monitor BP, renal fxn and K+ w/in 1 wk of initiation of therapy and w/ med titration
  • modify Rx if increase in Cr of 0.5 mg/dL, if BUN/Cr increase less than 50%, maintain dose, if increases by 100% switch HYDZ/ISOS
  • assess vol status if pt develops renal insufficiency or hypotension
  • physicians/pt may need to toelrate mild to moderate renal insufficiency to maintain ACEI/ARB therapy
32
Q

Use of BB in HF tx?

A
  • metoprolol XL, carvedilol, bisoprolol. toprol and zebeta may be better tolerated in pts w/ SBP
  • start when pt isn’t significantly congested - titrate q 2 wks, slower titration may be required
  • 1st line therapy:
    increase LVEF
    global sx improvement
    decrease hosp and mortality
    decrease sympathetic tim: antiarrhythmic activity benefit
  • all pts w/ stable HF w/ LVEF less than 40% should receive a BB, beneficial in those w/ or w/o DM2 or CAD, ok use in COPD, PAD
33
Q

SEs w/ BB up-titration?

A
  • coreg: vasodilator SEs:
    usually temporary, sep dosing of BB and ACEI, if persistent, reduce vasodilators
  • fluid retention:
    increase diuretic to restore baseline wt, delay up titration until wt is at baseline
  • bradycardia/AV block:
    check dig level, if persistent, consider cardiac pacing
34
Q

When is digoxin useful?

A
  • beneficial in pts w/ HFrEF, to decrease hospitalization for HF, no survival benefit
  • HF pts w/ AF, BB therapy usually more effective than digoxin in controlling ventricular rate, especially during exercise
  • don’t give in sig sinus or AV block unless pt has permanent pacemaker
  • reduce digoxin dose by 1/2 when used w/ amiodorone or BB therapy
  • lean body mass and impaired renal fxn can increase dig levels, toxcity may occur w/ lower dig levels w/ hypokalemia, hypomagnesmia, or hypothyroidism
  • ## most often dose should be 0.125 mg qd
35

60
Q

What are the 3 phases of progressive HF?

A
  • chronic disease management: dx, focus on extended survival, concurrent palliation of sxs, promoting self care (NYFC I-III)
  • supportive and palliative care phase: approp when pts reqr recurrent hospitalizations, focus on promoting comfort and QOL, palliation of sxs and advanced care planning (NYFC III-IV)
  • terminal care phase: pt has poor response despite max appropriate intervention (renal insufficiency, hypotension, fatigue, cachexia, diuretic resistance), focus on clarificaiton of tx decisions, advanced directives, comfort, QOL, support pt, family, prep for EOL and bereavement
61
Q

What are barriers to use of palliative care? Proposed Model of palliative care?

A
  • traditional model of medicine: cure and comfort are mutually exclusive, EOL discussions uncommon until days b/f death, half of DNR orders were written w/in 24 hrs of death
  • proposed integrated model of palliative care:
  • focus on sxs dosen’t preclude cont aggressive tx of disease
  • illness progresses, palliative care assumes larger role, is replaced w/ hospice at EOL
  • continues w/ bereavement care for survivors
