THE USE OF ATORVASTATIN FOR THE PREVENTION OF RECURRENT ATRIAL FIBRILLATION AFTER ELECTRICAL CARDIOVERSION IN PATIENTS WITH ISCHEMIC HEART DISEASE

Abstract

Aim. To study the effect of atorvastatin on the rate of atrial fibrillation (AF) recurrence after electrical cardioversion in patients with ischemic heart disease (IHD) and paroxysmal AF.Material and Methods. Sixty outpatients and inpatients (aged 30-70 y.o.) with IHD and paroxysmal AF were included into the open controlled randomized study immediately after the restoration of sinus rhythm by electrical cardioversion. Patients were randomized into 2 groups. Patients in Group 1 (n=30) received standard therapy recommended for maintenance of sinus rhythm in paroxysmal AF and atorvastatin (average dose 23.5±3.7 mg/day), and patients in Group 2 (n=30) had only the standard therapy. Routine blood analysis, blood chemistry (transaminases, creatine phosphokinase, creatinine, bilirubin, glucose, lipid profile), daily ECG monitoring, treatment safety evaluation were performed. AF relapse was considered as a primary endpoint.Results. Significant reduction in the rate of AF recurrence in was revealed in patients treated with atorvastatin. According to daily ECG monitoring AF relapse was recorded in 8.3 and 48% of patients in Group 1 and Group 2, respectively (p<0.001). Episodes of sinus tachycardia decreased on 52.3% (p<0.001) and 48,5% (p<0.01) in patients of the 1st and the 2 nd group, respectively.Conclusion. The addition of atorvastatin to the standard therapy for maintenance of sinus rhythm reduces effectively the rate of AF recurrence in patients with IHD and paroxysmal AF.
