Diuretic use in chronic heart failure lacks robust clinical trial data regarding benefits, adverse effects, and mortality impact, despite being the most potent drugs for relieving congestion.
Does diuretic use improve outcomes or cause harm in patients with heart failure?
This review emphasizes the historical reliance on diuretics for symptom relief in heart failure despite a lack of robust mortality data and potential risks of chronic use.
Several large well-designed clinical trials have shown that the use of diuretics is beneficial in patients with hypertension. However, similarly robust data regarding their role in chronic heart failure are lacking. Historically, diuretics were developed for treatment of sodium and water retention in oedematous disorders and clinically, they remain the most potent drugs available to relieve symptoms and eliminate oedema in the congested patient with heart failure. In the non-congested patient, however, diuretics continue to be used on a purely clinical basis without sufficient characterization of benefits, adverse effects, and potential influence on mortality. There are also concerns that chronic diuretic usage can cause adverse vascular effects, unfavourable neuroendocrine activation, electrolyte imbalances, and life-threatening arrhythmias. In this article, we review the limited evidence available regarding the benefits and perils of using diuretics in heart failure.
Gupta et al. (Fri,) conducted a review in Heart failure. Diuretics was evaluated. Diuretic use in chronic heart failure lacks robust clinical trial data regarding benefits, adverse effects, and mortality impact, despite being the most potent drugs for relieving congestion.
