Study of Low-Dose Colchicine Treatment to Prevent Recurrence of Atrial Fibrillation After Electrocardioversion

What this Trial Is About

Atrial fibrillation is the most common heart rhythm problem worldwide and increases the risk of heart failure, stroke, and death. Researchers expect its prevalence to rise, especially in people over 65 years old, with about one in three developing atrial fibrillation. Electrocardioversion is a procedure that restores normal heart rhythm but often results in the arrhythmia returning within a short time. This trial aims to study whether inflammation plays a role in this recurrence and if treating it can reduce the return of atrial fibrillation after electrocardioversion. The trial compares two groups one receives a daily oral dose of 0.5 mg Colchicine for three months, taken in the morning without a loading dose, alongside their usual treatments. The other group receives a matched placebo. This is a randomized, triple-blind Phase 3 study evaluating the effect of low-dose Colchicine on preventing atrial fibrillation recurrence after electrocardioversion. Participants will be monitored for recurrence of atrial fibrillation over six months following electrocardioversion. Researchers will assess the number of arrhythmia recurrences at one, three, and six months, the time to any repeat electrocardioversion, use of antiarrhythmic drugs, and hospitalizations. Safety and overall wellbeing will also be followed during this period, with the main outcome focused on arrhythmia recurrence within six months.
