Atorvastatin and persistent atrial fibrillation following cardioversion : a randomized placebo-controlled multicentre study

• AIMS: To evaluate the effect of atorvastatin in achieving stable sinus rhythm (SR) 30 days after electrical cardioversion (CV) in patients with persistent atrial fibrillation (AF). METHODS AND RESULTS: The study included 234 patients. The patients were randomized to treatment with atorvastatin 80 mg daily (n = 118) or placebo (n = 116) in a prospective, double-blinded fashion. Treatment was initiated 14 days before CV and was continued 30 days after CV. The two groups were well-balanced with respect to baseline characteristics. Mean age was 65 +/- 10 years, 76% of the patients were male and 4% had ischaemic heart disease. Study medication was well-tolerated in all patients but one. Before primary endpoint 12 patients were excluded. In the atorvastatin group 99 patients (89%) converted to SR at electrical CV compared with 95 (86%) in the placebo group (P = 0.42). An intention-to-treat analysis with the available data, by randomization group, showed that 57 (51%) in the atorvastatin group and 47 (42%) in the placebo group were in SR 30 days after CV (OR 1.44, 95%CI 0.85-2.44, P = 0.18). CONCLUSION: Atorvastatin was not statistically superior to placebo with regards to maintaining SR 30 days after CV in patients with persistent AF.
