Abstract

Aim: The aim of the present study is to evaluate the effect of amiodarone therapy in patients having atrial fibrillation (AF), complicating acute myocardial infarction (AMI) after achieving sinus rhythm spontaneously or by using electrical cardioversion. Material and Methods: Fifty patients with AMI who were initially in sinus rhythm, and thereafter complicated with AF in first 24 hours were included. Restoration of sinus rhythm was established spontaneously or by electrical cardioversion. Patients were randomized to amiodarone treatment group (1200 mg/day per oral for the first week, 800 mg/day per oral for second week, 600 mg/day per oral for third week, 200 mg/day per oral for fourth week) or to control group (without amiodarone). Evaluation for maintenance of sinus rhythm was performed after one month. Results: There was no statistically significant difference between the treatment group and the control group in terms of age, hypertension, diabetes mellitus, and chronic obstructive lung disease, left ventricular ejection fraction, left atrial dimension, thrombolytic therapy, and use of ß-blocker therapy. Spontaneous sinus rhythm recovery was observed in 14 of 26 patients in the amiodarone treatment group and 16 of 24 patients in the control group. There was no statistically significant difference in mortality. Three patients in the amiodarone group (11.5%) and 4 patients in the control group (16.6%) died at the end of one month observation period. There was also no statistically significant difference in respect to maintenance of sinus rhythm (p=0.311). All 19 patients in amiodarone group and 17 of 18 patients in control group maintained sinus rhythm. Conclusion: Amiodarone treatment has no impact on maintenance of sinus rhythm in patients experienced AF during the course of AMI in the first 24 hour who achieved sinus rhythm spontaneously or by using electrical cardioversion.

Özet

Amaç: Bu çalışmada akut miyokard infarktüsü (AMI) sırasında atriyal fibrilasyon (AF) gelişen, spontan veya elektriksel kardiyoversiyon ile sinüs ritmi sağlanan hastalara amiodaron tedavisi verilerek, birinci ay sonunda sinüs ritminin korunma oranına ve amiodaron tedavisinin etkisine bakılması amaçlandı. Gereç ve Yöntem: Çalışmaya akut miyokard infarktüsü tanısıyla ve sinüs ritminde yatırılan, fakat ilk 24 saatlik izlemde AF gelişen, sonradan spontan veya elektriksel kardiyoversiyon ile sinüs ritmi sağlanan 50 hasta alındı. Hastalar amiodaron tedavisi (ilk hafta 1200 mg/gün, ikinci hafta 800 mg/gün, üçüncü hafta 600 mg/gün, dördüncü hafta 200 mg/gün oral amiodaron) alan ve almayan tedavi gruplarına randomize edildiler. Birinci ayda hastaların sinüs ritmi korunma oranlarına bakıldı. Bulgular: Çalışmaya alınan 50 hastada, amiodaron tedavisi alan ve almayan grupta yaş, hipertansiyon (HT), diabetes mellitus (DM), kronik obstrüktif akciğer hastalığı (KOAH), sol ventrikül ejeksiyon fraksiyonu (EF), sol atrial çap (LAÇ), trombolitik tedavi, beta bloker tedavisi bakımından istatiksel açıdan önemli bir fark yoktu. Her iki grupta da hastaların çoğunda (%60) spontan yolla sinüs ritmi sağlanmış olup, amiodaron tedavisi alan grupta 26 hastanın 14'ünde, almayan grupta 24 hastanın 16'sında spontan yolla sinüs ritmi sağlanmıştır. Bir aylık takipte amiodaron tedavisi alan grupta toplam 3 ölüm (%11.5), almayan grupta toplam 4 ölüm (%16.6) saptandı, aralarında istatiksel açıdan fark yoktu. Birinci ayda amiodaron tedavisi alan 19 hastanın 19'u, almayan 18 hastanın 17'si sinüs ritmindeydi, aralarında istatiksel açıdan belirgin fark yoktu (p=0.311). Sonuç: İlk 24 saatte AF gelişen akut MI'lı hastalarda spontan yolla veya elektriksel kardiyoversiyonla sinüs ritmi sağlandıktan sonra optimal tedaviye eklenen amiodaron tedavisinin, sinüs ritmi idamesinde ek bir faydası olmadığı saptandı.
