Q

What is the difference between HFrEF & HFpEF?

A
  • HFrEF): EF ≤ 40% & it is a pumping problem
  • HFpEF): EF ≥ 50% & it is a filling issue
21
Q

What BNP levels are indicative of HF?

A

> 500 pg/mL (90% positive predictive value)

22
Q

At what BNP level could someone present with dyspnea?

A

300 pg/mL

23
Q

What defines NYHA Class 1?

A

No limitation of physical activity

24
Q

What defines NYHA Class 2?

A

Slight limitation of physical activity. Comfortable at rest; activity may cause clinical symptoms.

25
Q

What defines NYHA Class 3?

A
  • Marked limitation of physical activity.
  • Comfortable at rest; low physical activity causes clinical symptoms.
26
Q

What defines NYHA Class 4?

A
  • Unable to perform any physical activity without symptoms & has symptoms at rest
27
Q

What defines ACC/AHA class A?

A
  • No structural evidence of CV disease.
  • No functional limitation in ordinary physical activity.
28
Q

What defines ACC/AHA class B?

A
  • Evidence of minimal structural CV disease.
  • Comfortable at rest but slight limitation during ordinary activity.
29
Q

What defines ACC/AHA class C?

A
  • Evidence of moderately severe structural CV disease.
  • Comfortable only at rest w/ limitation in activity d/t clinical symptoms.
30
Q

What defines ACC/AHA class D?

A
  • Objective evidence of severe structural CV disease.
  • Clinical symptoms at rest.
31
Q

What are the S/S of acute HF?

A
  • High ventricular filling pressures
  • Low CO
  • HTN or hypotension
32
Q

What 3 types of drugs are used in acute HF?

A
  • Diuretics: Loop diuretics improve symptoms rapidly
  • Vasodilators: Nitroglycerin and nitroprusside
  • Inotropic drugs: Epinephrine, norepinephrine, dopamine, dobutamine, or phosphodiesterase inhibitors
33
Q

What INTERMACS class/es need/s immediate support?

A

Class 1 & 2

34
Q

What diuretic family is recommended for HF therapy?

A

Thiazide and/or loop diuretics

35
Q

What is the first-line therapy for patients presenting in acute heart failure?

A

Diuretics

36
Q

Beta blockers are beneficial for what type of HF

A

Beneficial for the treatment of HFrEF

37
Q

ACE-I are recommended for what kind of HF?

A

HFrEF

38
Q

What medication combination has a favorably long-term outcome for HF?

A

Therapy with ACE-I and β-blockers

39
Q

For whom are ARBs useful when it comes to HF?

A

Useful for control of arterial pressure in patients with HTN and HFpEF

40
Q

How do vasodilators help a CHF Pt?

A

Decreases resistance to LV ejection → results in increased SV and decreased ventricular filling pressures

41
Q

What are the qualifications for a PPM?

A
  • NYHA 3 or 4 &
  • LVEF < 35% &
  • QRS duration of 120–150 milliseconds
42
Q

What is the gold standard for surgical management of HF?

A

Cardiac transplantation

43
Q

What is bridge to recovery?

A

Require temporary ventricular assistance to allow the heart to recover its function

44
Q

What is bridge to therapy?

A

Awaiting cardiac transplantation

45
Q

What is the bridge to decision stage?

A

Pt is on inotropic drugs or IABP with potentially reversible medical conditions

46
Q

What is the destination therapy stage?

A

Advanced HF who are not transplant candidates → LVAD

47
Q

When are diuretics D/C’ed for someone w/ HF going for surgery?

A

D/C diuretics on the day of surgery

48
Q

What would be the best anesthesia type for someone with HF

A

Neuraxial anesthesia – might be best but may depend on surgeon & Pt compliance
