[Effectiveness and tolerance of digitaloid treatment in cardiac insufficiency]
Insights
Digitaloids effectively treat severe cardiac failure, particularly in patients with reduced ejection fraction. Discontinuing digitaloids in milder heart failure may be safe if other treatments continue.
Area of Science:
- Cardiology
- Pharmacology
Context:
- Digitaloids have been used for cardiac failure treatment, but their efficacy in sinus rhythm remains debated.
- The inotropic effects of digitaloids are established at therapeutic doses in humans.
Purpose:
- To evaluate the effectiveness of digitaloids in cardiac failure patients with sinus rhythm.
- To identify patient subgroups that benefit most from digitaloid therapy.
Summary:
- Hemodynamic benefits of digitaloids are more pronounced in severe cardiac failure.
- Patients with chronic severe heart failure, ventricular dilatation, reduced ejection fraction, and gallop rhythm respond best.
- Suspending digitaloids in functional class II/III ischemic heart failure may not worsen outcomes if diuretics/vasodilators are maintained.
Impact:
- This research refines digitaloid treatment strategies for heart failure.
- Identifies specific patient profiles for optimal digitaloid therapy, improving clinical decision-making.
Abstract:
Ever since digitaloids have been used in the treatment of cardiac failure, their effectiveness in cases with sinus rhythm has been controversial. Nevertheless, their inotropic effect at therapeutic concentrations has been well demonstrated in man. The haemodynamic benefit in cardiac failure is greater the more severe the condition. Recent studies have shown that the patients who respond best to digitaloid treatment are those with chronic severe heart failure with ventricular dilatation, reduction in the ejection fraction and a gallop on auscultation. In contrast, when digitaloid treatment is suspended in patients with functional class II or III ischaemic heart failure, there does not appear to be any aggravation provided diuretic and/or vasodilator treatment is continued.
