Digitalis: its place in therapy.

J Somberg, D Keefe, B Levitt

    Journal of Clinical Pharmacology
    |October 1, 1985

    Summary
    This summary is machine-generated.

    Digitalis, despite its narrow therapeutic index, offers a small but significant hemodynamic and clinical benefit in heart failure patients. It remains a valuable tool for supraventricular arrhythmias and impaired left ventricular function.

    Area of Science:

    • Cardiology
    • Pharmacology

    Background:

    • Digitalis has been used for over 200 years, but its narrow therapeutic ratio limits its application.
    • Recent studies have questioned the utility of digitalis in patients with congestive heart failure and recent myocardial infarction.

    Purpose of the Study:

    • To evaluate the hemodynamic and clinical effects of digitalis in patients with specific cardiac conditions.
    • To determine the role of digitalis in the modern therapeutic armamentarium for heart failure and arrhythmias.

    Main Methods:

    • Review of findings from rigorously controlled clinical studies.
    • Analysis of the unique properties of digitalis, including inotropic, dormotropic, and vagomimetic effects.

    Main Results:

    • Controlled studies indicate a small but definite hemodynamic and clinical improvement in patients receiving digitalis.

  • Congestive heart failure can be managed effectively without digitalis, but it offers an additional therapeutic option.

    • Conclusions:

    • Digitalis, when used judiciously, provides unique benefits for patients with supraventricular arrhythmias and compromised left ventricular function.
    • While not essential for all heart failure cases, digitalis remains a valuable agent in specific clinical scenarios.
