Cardiology Flashcards

1
Q

Tx CAD

A
  • Always: ASA, statin, beta-blocker, ACE-i
  • Nitrate: if continued chest pain
    • CONT if R-sided infarct (leads II, III, avF)
  • Clopidogrel: if stented
    • x 1 mo for bare metal
    • x 1 yr for drug-eluting (best)
  • Heparin + Clopidogrel Load if
    • NSTEMI
    • High pretest probability CAD
  • Other:
    • Morphine - CONT in R-sided infarct (venodilator)

Q

Drugs CONT in R-sided infarct

A
  1. Nitrate
  2. Morphine

Both are venodilators, decreasing preload. R-sided infarct is preload-dependent

Q

Next step in R-sided infarct

A

IVF

(b/c it is preload-dependent and this will increase preload. Don’t be tricked by JVD. IVF is okay if no signs of pulmonary congestion)

Q

If recent onset of CP, NSTEMI suspected, cardiac enzymes negative, what is the next step?

A

Repeat cardiac enzymes at 6 hours

Considered negative after 2 sets of negative enzymes

Q

Troponins vs CK-MB

A
  • Troponins
    • rise more immediately
    • declines slower
    • peaks at 18 hours
  • CK-MB
    • Declines more quickly
    • Measure to test for repeat infarct

Q

When to use different types of stress testing?

EKG, ECHO, Nuclear

A
  • EKG
    • Test of choice, no baseline abnormality

Q

Tx: Chronic CHF

A
  • Always: beta-blocker and ACE-i
  • Stage II: Add Furosemide
  • Stage III: 1 and 2. Add Spironolactone or Hydralazine + Isosorbide Dinitrate
  • Stage IV: Inotrope: Dobutamine or Milrenone. VAD bridge to transplant
  • Stage I-III and EF < 35%: AICD

Q

Tx: CHF Exacerbation

A

“LMNOP”

  • L = Lasix
  • M = Morphine
  • O = Oxygen
  • P = Position

Note: initiating a beta-blocker during acute exacerbation is CONTRA (acutely decreases EF). If already on it, may continue

Q

Differentiating CHF vs ARDS?

A

Q

HTN recommendations (JNC-8)

A
  1. >/= 60 + No Dz = 150/90 goal
  2. Everyone else = 140/90 goal
  3. CCB, Thiazide, or ACE-i as first line
  4. (>75) or AA = No Ace-i
  5. CKD = ACE-i/ARB (overrules #4)
  6. Don’t use beta blockers alone for HTN (add for CAD/MI)
