Study Notes
Inotropic Drugs and Heart Failure Treatments
- Digoxin enhances contractility by increasing Ca++ concentrations and acting on Na-K ATPase and Na-Ca Exchange
- Digoxin has mechanical effects on the heart, including increased myocardial contractile force and decreased duration of systole
- Digoxin has electrical effects on the heart, such as slowing the sinus rate and indirect and direct effects on AV node and Purkinje fibers
- Digoxin has extracardiac effects and toxicities, including GI symptoms, mental symptoms, and vision disturbances
- Milrinone, a phosphodiesterase inhibitor, increases inward calcium flux in the heart and inhibits cAMP phosphodiesterase
- Milrinone's indications include short-term therapy and its adverse effects are fewer in the short term but include increased mortality in the long term
- Dobutamine, a beta1 and beta2 agonist, increases cardiac output and is used for short-term support of cardiac output in advanced heart failure
- Dopamine acts as an agonist at beta1 and dopamine1 receptors and is used for short-term therapy to increase splanchnic and renal blood flow
- Dobutamine is the drug of choice in acute decompensated heart failure, while dopamine is preferred in some situations with low blood pressure
- New treatments for heart failure include Corlanor (Ivabradine) and the PARADIGM-HF trial for Angiotensin-receptor and neprilysin inhibition with Entrestoâ„¢ (sacubitril and valsartan)
- Neprilysin is a neutral endopeptidase involved in the metabolism of vasoactive peptides and its inhibition results in higher levels of peptides with vasodilator properties
- Neprilysin substrates relevant to cardiovascular physiology include ANP, BNP, CNP, Ang-II, adrenomedullin, substance P, bradykinin, endothelin, and urodilatin
