Overview

  1. Agents that increase intracellular cAMP
  2. Agents that affect sarcolemmal ion pumps/channels
  3. Agents that modulate intracellular calcium mechanisms by either:
  4. Drugs having multiple mechanisms of action
    • Pimobendan
    • Vesnarinone

Digoxin

  • Inhibits Na,K+-ATPase resulting in an increase in intracellular Na+, extracellular Ca2+ exchange increasing the velocity and extent of sarcomere shortening.
  • ACC/AHA recommend digoxin for symptomatic patients with left ventricular systolic dysfunction.
  • Commonly used in patients with heart failure and atrial fibrillation to reduce the ventricular response rate.
  • Mortality has not been shown to be improved with use of digoxin[1], but the use of digoxin has been associated with a reduction in hospitalization in the RALES study.
  • There is no need to load a CHF patient with digoxin. For the majority of patients with normal renal function, a daily dose of 0.25 mg of digoxin is usually adequate. In the older patient or in those patients with renal impairment, a dose of 0.125 mg per day may be adequate.
  • Drugs that increase the concentration of digoxin include antibiotics and anticholinergic agents as well as amiodarone, quinidine and verapamil.
  • In the RALES study, a level of < 1 ng/ml was associated with efficacy. Levels above 1 ng/ml were not associated with greater efficacy and were associated with higher mortality.

ACC/AHA Guidelines- Digitalis (DO NOT EDIT) [2][3]

Class IIa

1. Digitalis can be beneficial in patients with current or prior symptoms of heart failure and reduced left ventricular ejection fraction (LVEF) to decrease hospitalizations for heart failure. [1][4][5][6][7][8][9][10] (Level of Evidence: B)

Dobutamine

  • Activates beta-1 receptors resulting in enhanced cardiac contractility.
  • Long-term dobutamine infusions are arrhythmogenic and increase mortality.
  • Dobutamine also slightly reduces afterload

Dopamine

  • Unique dose dependent mechanism of action.
  • At low doses: (≤2 µg/kg/min), selective dilation of splanchnic and renal arterial beds. assists in increasing renal perfusion.
  • At intermediate doses: (2 to 10 µg/kg/min), increased norepinephrine secretion results in increased cardiac contractility, heart rate and systemic vascular resistance.
  • At higher doses: (5 to 20 µg/kg/min), direct alpha-adrenergic receptor stimulation increases systemic vascular resistance.

Milrinone

  • Phosphodiesterase-III inhibitor that enhances cardiac contractility by increasing intracellular cyclic adenosine monophosphate (cAMP).
  • Potent pulmonary vasodilator that may benefit some patients with pulmonary hypertension.
  • Unlike dobutamine milrinone is beneficial in decompensated heart failure patients who are on beta-blocker therapy.
  • Long term milrinone infusions are arrhythmogenic, and increase mortality.

ACC/AHA Guidelines- Positive Inotropic Drugs [2][3]

Class III

1. Long-term use of an infusion of a positive inotropic drug may be harmful and is not recommended for patients with current or prior symptoms of heart failure and reduced left ventricular ejection fraction (LVEF), except as palliation for patients with end-stage disease who cannot be stabilized with standard medical treatment. (Level of Evidence: C)
