Acute exacerbation of CHF

  • Treatment:
    • Nitrates (nitroglycerin)
    • Oxygen
    • Loop Diuretics
    • Inotropic Drugs (dobutamine, milrinone, amrinone)
    • Positioning (with legs down)

Aortic Dissection

  • Stanford type A
    • Presentation:
      • involves ascending aorta
    • Treatment: 
      • admit to the ICU
      • IV B-blocker to control the BP
      • emergency surgical repair
  • Stanford type B
    • Presentation:
      • confined to descending aorta
    • Treatment:
      • B-blocker

Aortic Regurgitation

  • Cause:
    • infective endocarditis
  • Treatment:
    • Ace inhibitor or CCB

Atrial Fibrillation

  • If present > 48 hrs:
    • TEE
    • if no thrombus is present:
      • cardioversion followed by anticoagulation
    • if thrombus is present:
      • anticoagulate for 3 weeks, then repeat TEE
  • If present < 48 hrs:
    • Cardioversion +/- anticoagulation depending upon risk

CABG

  • Major indications:
    • Left main coronary artery stenosis > 50%
    • Severe 3 vessel coronary artery stenosis

CHF

  • Medication reduce mortality:
    • ACE inhibitors and ARBS
    • B-blockers
      • bisoprolol
      • carvedilol
      • extended-release metoprolol
    • Aldosterone antagonists
      • spironolactone
      • eplerenone

Pericarditis

  • Dx:
    • ECG
      • diffuse ST elevation
      • PR depression
      • diffuse T wave inversion (late)
    • Echocardiogram
      • usuall normal
      • +/- pericardial effusion
    • Chest Xray
