  37. 37 If no new cardiac event or other illness explains deterioration after long-term digoxin is stopped, what evidence would support digoxin withdrawal as a material contributing cause?

What should a physician do to determine whether a long-term digoxin indication still exists before permanently discontinuing it?

The short version: a physician should check the original indication, current ejection fraction, rhythm, renal function, and whether the patient still meets the trial criteria that justify digoxin.

The evidence from the DIG trial (n=6800) shows digoxin reduces heart failure hospitalizations but does not affect overall mortality [1]. The RADIANCE and PROVED trials both showed that withdrawing digoxin from stable heart failure patients on optimal therapy led to clinical deterioration [1]. So if the original indication was heart failure with reduced ejection fraction, the physician needs to confirm that the patient still has a reduced EF and is on modern therapy (ACE inhibitors, beta-blockers). If the EF has normalized or the patient is on no other heart failure drugs, the benefit is less certain.

For atrial fibrillation, the evidence is weaker. One study of 1269 patients found beta-blockers reduced mortality (RR 0.58) while digoxin alone did not (RR 0.97) [4]. Digoxin controls heart rate but does not improve survival in this group. If the patient has atrial fibrillation and is rate-controlled on a beta-blocker alone, digoxin may no longer be needed.

The physician should also check renal function. Chronic renal failure alters digoxin handling: a rat study found 4-fold higher kidney-to-plasma digoxin accumulation in renal failure [6]. In patients with impaired kidneys, digoxin levels rise and toxicity risk increases. A serum digoxin level and creatinine clearance are essential.

Magnesium status matters too. One study of digitalised atrial fibrillation patients found that those with frequent ventricular ectopy retained more magnesium on a loading test, suggesting magnesium deficiency may contribute to digoxin-related arrhythmias [5]. Checking serum magnesium and correcting deficiency is a simple step that is almost never done.

The physician should also check for ICDs. One study found digoxin use in ICD recipients was associated with 4-fold higher odds of shock events (OR 4.07) and more electrical storms [3]. If the patient has an ICD, the risk-benefit calculation shifts.

The 2015 BMJ meta-analysis found that in randomized trials, digoxin had a neutral effect on mortality (RR 0.99) but reduced hospitalizations (RR 0.92) [2]. In observational studies after adjustment, digoxin was associated with increased mortality (adjusted RR 1.18) [2]. That gap means the patients who get digoxin in practice may be sicker or different from trial populations. The physician should ask: does this patient still look like the trial patients who benefited?

My call: the physician should check the original indication, current LVEF, rhythm, renal function, serum digoxin level, magnesium, and whether the patient has an ICD. If the original indication is gone (normal EF, no atrial fibrillation, no symptoms) and the patient is stable on modern therapy, discontinuation is reasonable with monitoring. If the indication still holds, stopping risks deterioration. The evidence supports digoxin for specific patients, not for everyone who happens to be on it. Confidence: moderate.
