Q

What is Non-pharmacological management for heart failure?

A
  • Education for patients and carers
    May include self-management advice (e.g. diuretic adjustment within pre-defined and individualised limits)
  • Self-monitoring of weight
    Gain of >2kg in 2-3 days seek advice or self-adjust diuretic dose
  • Dietary measures
    Reduce salt intake (care with salt substitutes)
    Fluid restrict in advanced heart failure (1.5-2.0L/day)
    Moderate alcohol intake
    Weight reduction if obese
  • Other lifestyle issues
    Smoking cessation
    Exercise; best rest in acute heart failure, exercise training programs encouraged for stable patients

18
Q

What is self monitoring of weight in heart failure patients?

Study These Flashcards
A

Gain of more than 2kg in 2-3, seek advice or self adjust diuretic dose

19
Q

  • Moderate alcohol intake
  • Weight reduction if obese
20

  • ACE inhibitors
  • Angiotensin receptor blockers
  • Beta blockers
  • Aldosterone antagonists
  • Digoxin
  • Vasodilators
  • Sacubitril/ Valsartan
  • Dapagliflozin
21
Q

What monitoring is required with diuretics?

Study These Flashcards
A
  • Renal function and electrolytes
  • Monitor weight and adjust dose
22
Q

What are the counseling points for diuretics?

Study These Flashcards
A
  • Counsel patients on flexible dosing time
  • Inconvenience as you need to pee a lot
  • Diuretics can cause gout
23
Q

What are diuretics place in therapy?

Study These Flashcards
A

Used to control symptoms

24
Q

How are diuretics usually given?

Study These Flashcards
A
  • Loop diuretic is usually given
  • Combination of loop diuretic and thiazide may be required
  • May be given orally/ intravenously
25
What is furosemide 40mg equivalent to?
Bumetamide 1mg
26
What are ACE inhibitor place in therapy?
- Improve survival and symptoms and reduce hospitalization - Indicated for all grades of heart failure unless contraindicated
27
What monitoring is required with ACE inhibitors?
Renal function and electrolytes before and after each dose change and initial dose
28
When can you combine an ARB with an ACE inhibitor?
In patients who remain symptomatic for additional benefits
29
What is the choice for ARB?
- Candesartan - Valsartan
30
What are beta blockers place in therapy?
- Reduce hospitalization, morbidity and mortality - Indicated for stable patients in addition to an ACE inhibitor or angiotensin receptor blocker
31
What is the choice of beta blocker?
- Carvedilol - Bisoprolol - Nebivilol - Metopralol
32
What are the practical points for beta blockers?
- Patients heart failure should be stable at initiation - Heart failure symptoms may be exacerbated during titration - Avoid abrupt withdrawal
33
What beta blocker is better for a hypertensive patient with heart failure?
Bisoprolol - a cardio selective beta blocker
34
What is ivabradines place in therapy?
- Reduces mortality and hospitalization - NYHA II- IV - Used in patients intolerant to beta blockers or in addition to beta blocker if HR>75
35
What are the practical points of ivabradine?
- Avoid grapefruit - Bradycardia - Sinus Rythm
36
What are aldosterone antagonists place in therapy?
- Spironolactone reduces morbidity and mortality when added to usual treatment in advanced heart failure patients ( Class III-IV) - Eplerenone reduces morbidity and mortality when added to usual treatment in MI complicated by heart failure or in spironolactone intolerant heart failure patients
37
What needs to be checked before initiation of aldosterone antagonists?
Serum creatinine and potassium levels
38
What is the initial dose of spironolactone?
12.5-25mg OD
39
What is the initial dose of eplerenone?
25mg OD
40
When do serum and potassium levels need to be re checked when first given a aldosterone antagonist?
After 4-6 days
41
What are vasodilators place in therapy?
- Hydralazine combined with isosorbide dinitrate improve survival - Only indicated if patient remains symptomatic or if all other options have been considered
42
What are heart failure exacerbating drugs?
- NSAIDS/ COX inhibitors - Rate limiting calcium channel blockers - Chemotherapy - Anti psychotic drugs - Glitazones - Corticosteroids - Medicines with a high sodium content
