OBJECTIVE: To assess and compare the safety and efficacy of allapinine and quinidine bisulphate in the treatment of patients with persistent atrial fibrillation after cardioversion. Design--Prospective, randomised, open study. Patients--73 consecutive patients (men only, mean age 44 ± 11 years) with persisnent atrial fibrillation and flutter. Interventions--37 patients were randomised to allapinine (ALP) (1.5 mg/kg/d), 36 to quinidine bisulphate (QUIN) (15 mg/kg/d) with subsequent successful pharmacological or electrical cardioversion. Main outcome measures--Recurrence of atrial fibrillation or side effects.
RESULTS: In the ALP group 15 of the 37 patients developed atrial fibrillation up to 12 month of follow-up, while in the QUIN group 20 patients developed atrial fibrillation and 5 experienced significant side effects. Relative risk (RR) (ALP vs QUIN) 0.58 (95% CI 0.37-0.91, p < 0.02). The number needed to treat (NNT) was (-3.48) (14.2-1.97 harm). When 5 patients with significant side effects were excluded from the analysis RR was 0.62 (95% CI 0.39-1.0, p = 0.052) and NNT--(-4.1) (122.7-2.1 harm) but power of the study was too low--67%.
CONCLUSION: Allapinine is as effective as quinidine bisulphate in the long term treatment of patients with persistent atrial fibrillation after successful cardioversion but causes significantly less side effects.
