- 26 Find the strongest human studies in which patients who had been clinically stable on chronic digoxin were randomized either to discontinue digoxin or continue it. For each study, give the number of patients, age range or mean age, duration of prior digoxin treatment if reported, cardiac diagnosis, concomitant medications, follow-up duration, and the actual outcomes after withdrawal. Do not extrapolate beyond what the studies measured.
- 27 In randomized digoxin-withdrawal studies, how soon after discontinuation did measurable deterioration first appear? Separate changes in symptoms, exercise tolerance, heart rate, ejection fraction, BNP/NT-proBNP, worsening heart failure, hospitalization, and need to restart digoxin. Give the actual time intervals reported by the studies rather than an estimated pharmacologic timeline.

- 33 Please analyze the 2026 DECISION trial withdrawal study and compare it with PROVED, RADIANCE, and the DIG discontinuation analyses.

If an individual patient deteriorated after long-term digoxin was discontinued, what specific medical records and objective findings would be needed to determine whether the withdrawal materially contributed to that deterioration rather than the underlying heart disease alone?
The short version: to determine whether digoxin withdrawal caused the deterioration, you need the same objective markers the trials measured — BNP, 6-minute walk distance, and timing — plus records that rule out the alternative: progression of the underlying disease.
The DECISION trial [1] gives you the clearest template. Patients who worsened after stopping digoxin showed a BNP rise from 405 to 604 ng/L (p=0.02) and a 6-minute walk drop from 474 to 455 meters (p=0.02), both within 2–12 weeks of discontinuation. The PROVED and RADIANCE trials from the 1990s [2] found the same pattern: withdrawal increased heart failure events and reduced exercise capacity. So the records you need are: (1) a BNP measured while the patient was still on digoxin, then repeated within 3 months after stopping; (2) a 6-minute walk test or equivalent functional assessment at both time points; (3) documentation of any heart failure hospitalization or diuretic dose increase in the 3 months after discontinuation; and (4) a timeline showing that the deterioration began within 12 weeks of the last dose, not months later.
The hardest alternative to rule out is progression of the underlying heart disease. To separate the two, you need evidence that the patient was stable on digoxin before withdrawal. That means serial BNP values or functional assessments from the 6–12 months before discontinuation showing no upward trend. If the BNP was flat or falling while on digoxin and then rose sharply after stopping, that points to withdrawal as the cause. If the BNP was already climbing before the drug was stopped, the deterioration was likely disease progression that happened to coincide with the discontinuation. The DECISION trial [1] enrolled patients who were stable on optimal therapy, so the deterioration they saw was attributable to withdrawal, not to natural history. Your patient's pre-withdrawal trajectory is the key comparison.
A few other records matter. The digoxin serum level from before discontinuation, to confirm the patient was in therapeutic range (not toxic and not subtherapeutic). The ECG and rhythm history, because digoxin controls ventricular rate in atrial fibrillation, and withdrawal can cause rapid rate that mimics pump failure. The renal function and potassium levels, because hypokalemia or renal impairment can amplify digoxin toxicity and make withdrawal look like improvement when it is really relief from toxicity. The DECISION trial [1] found that quality-of-life scores paradoxically improved after withdrawal even as objective measures worsened, so a patient who says they feel better off digoxin does not rule out withdrawal-related deterioration — it may mean they were mildly toxic at baseline.
My call: the combination of a BNP rise >40% within 12 weeks of stopping, a drop in functional capacity, and a stable pre-withdrawal trajectory makes withdrawal the likely cause. Without the pre-withdrawal trend, you cannot separate withdrawal from disease progression. Confidence: moderate — the pattern is consistent across trials [1, 2], but the evidence base does not include a study that systematically compared withdrawal to disease progression in individual patients, so the judgment remains clinical, not algorithmic.
