Agents with inotropic properties for the management of acute heart failure syndromes. Traditional agents and beyond.
Treatment with inotropic agents is one of the most controversial topics in heart failure. Initial enthusiasm, based on strong pathophysiological rationale and apparent empirical efficacy, has been progressively limited by results of controlled trials and registries showing poorer outcomes of the patients on inotropic therapy. The use of these agents remains, however, potentially indicated in a significant proportion of patients with low cardiac output, peripheral hypoperfusion and end-organ dysfunction caused by heart failure. Limitations of inotropic therapy seem to be mainly related to their mechanisms of action entailing arrhythmogenesis, peripheral vasodilation, myocardial ischemia and damage, and possibly due to their use in patients without a clear indication, rather than to the general principle of inotropic therapy itself. This review will discuss the characteristics of the patients with a potential indication for inotropic therapy, the main data from registries and controlled trials, the mechanism of the untoward effects of these agents on outcomes and, lastly, perspectives with new agents with novel mechanisms of action. Topics: Acute Disease; Cardiotonic Agents; Digoxin; Dobutamine; Etiocholanolone; Exercise Test; Heart Failure; Hemodynamics; Hospitals, Group Practice; Humans; Hydrazones; Prognosis; Pyrazines; Pyridazines; Quinolines; Sarcoplasmic Reticulum Calcium-Transporting ATPases; Simendan; Treatment Outcome; Urea; Vasodilator Agents | 2009 |
Reassessment of digoxin and other low-dose positive inotropes in the treatment of chronic heart failure.
Digoxin and other low doses of drugs that have inotropic properties may have an important role to play in the therapy of patients with chronic heart failure. There is convincing evidence that digoxin is effective in relieving the signs and symptoms of heart failure due to systolic dysfunction. While earlier results with some of the other agents have been disappointing, recent data suggest that a reevaluation of these agents is necessary. There is now compelling evidence that lower doses of these agents may be clinically useful without necessarily having any significant hemodynamic effects. The recent experience with vesnarinone is especially promising in showing that therapy with these agents may improve survival in addition to improving clinical status. It is becoming recognized that hemodynamic activity should not necessarily be a prerequisite for clinical utility for those agents. The neuroendocrine and electrophysiologic effects of many of these agents, including digitalis, remain incompletely characterized and may play an important role in their therapeutic benefit. It appears that certain drugs that have inotropic properties may be effective only when their inotropic effects are not readily demonstrated. Further research into the appropriate mechanisms of action and proper dosing of these drugs may lead to a renewed interest in the use of positive inotropes for chronic heart failure. Topics: Adrenergic beta-Agonists; Cardiotonic Agents; Digoxin; Double-Blind Method; Drug Evaluation; Electrophysiology; Heart Failure; Hemodynamics; Humans; Myocardial Contraction; Neurosecretory Systems; Phosphodiesterase Inhibitors; Pyrazines; Quinolines | 1994 |
