1. 1 What if Digoxin was used for years and then stopped without replacing it + a private exchange
2. 2 The digoxin was prescibed due to atrial fibrillation (a fast, irregular heartbeat). + a private exchange
3. 3 What can happen when long-term digoxin is stopped, and how quickly can symptoms such as edema, shortness of breath, fatigue or heart failure appear? + a private exchange
4. 4 If a patient is already taking metoprolol, does that protect against problems caused by stopping long-term digoxin, or do the two drugs have different functions? + a private exchange
5. 5 If one digoxin result is 2.65 nmol/L at 3 hours 52 minutes after a dose and another is 1.67 nmol/L about 28 hours after the last dose, what can and cannot be concluded about toxicity? + a private exchange
6. 6 Is “no clear indication” sufficient reason to abruptly stop digoxin after 30 years of use, or should the original indication and current cardiac condition first be established? + a private exchange
7. 7 If digoxin is stopped in an elderly patient who remains on metoprolol, what monitoring should be done afterward to detect worsening heart failure or loss of rate control? + a private exchange
8. 8 What findings would help determine whether worsening edema, fatigue and shortness of breath after stopping digoxin were caused by the withdrawal rather than the underlying heart disease? + a private exchange
9. 9 If digoxin had been controlling previously unrecognized heart failure, what could happen after it is stopped while metoprolol is continued? + a private exchange
10. 10 Can stopping digoxin unmask previously compensated heart failure even if the patient does not deteriorate immediately? + a private exchange
11. 11 What evidence would make it unlikely that stopping digoxin contributed to a patient's later heart failure? + a private exchange
12. 12 How quickly should serum digoxin fall after the drug is completely stopped in an elderly patient with normal kidney function? + a private exchange
13. 13 What should be documented when a physician tells an elderly patient to stop long-term digoxin? + a private exchange
14. 14 n an elderly patient who had taken digoxin continuously for approximately 30 years, if the physician decides to stop it but the original indication is uncertain and an echocardiogram is still pending, what clinical follow-up during the first days, weeks, and months would help determine whether withdrawal is causing loss of previously compensated cardiac function? + a private exchange
15. 15 What objective findings after digoxin withdrawal would support loss of previously compensated heart failure rather than unrelated progression of underlying heart disease? + a private exchange
16. 16 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.
17. 17 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.
18. 18 In digoxin-withdrawal trials, did every patient deteriorate immediately after stopping, or did some patients remain apparently stable initially and deteriorate later? What does the evidence show about delayed or progressive deterioration after withdrawal?
