Heart failure (HF) is the leading cause of hospitalization among older adults. Digoxin has been shown to reduce hospitalization due to worsening HF. However, at the commonly prescribed dose of 0.25 mg/day, digoxin does not reduce mortality. New data suggest that at low doses (0.125 mg/day or lower) digoxin not only reduces hospitalization due to HF, but may also reduce mortality. Further, at lower doses, it also reduces the risk of digoxin toxicity and obviates the need for routine serum digoxin level testing. Digoxin in low doses should be prescribed to older adults with symptomatic HF.
Key words: chronic heart failure, older adults, treatment, digoxin, update.
