Atriyal Fibrilasyon Hastalarında Epikardiyal Yağ Kalınlığı ile Kardiyoversiyon Başarısı Arasındaki İlişki

Amaç Epikardiyal yağ dokusunun aritmojenik etkileri bilinmektedir. Bu çalışmada bu aritmojenik etkinin kardiyoversiyon (KV) başarısı üzerine olan etkisinin araştırılması amaçlanmıştır. ( Sakarya Tıp Dergisi 2019, 9(1):125-130 ). Gereç ve Yöntems Çalışmaya sinüs ritminin sağlanması amacıyla KV uygulanan 100 atriyal fibrilasyon (AF) hastası alınmıştır. Hastalar iki gruba ayrıldı; sinüs ritmi sağlanan hastalar grup 1, sağlanamayan hastalar grup 2 olarak değerlendirildi. Çalışma popülasyonunun karakteristik özellikleri, standart 2 boyutlu ekokardiyografik ölçümler ve doku doppler ölçümleri kaydedildi. Bulgular Grup 1’de 94 ( ortalama yaş 59,5+-14,1) grup 2’de 6 (ortalama yaş 59+-8,7) hasta vardı. Temel hasta özellikleri açısından gruplar arasında fark yoktu. Sol atriyum çapı, sol ventrikül çapları, septal duvar kalınlıkları, ejeksiyon fraksiyonu ve sol ventrikül kitle indeksi gibi ekokardiyografik parametreler açısından her iki grup benzerdi. Epikardiyal yağ kalınlığı (EYK) grup 2 hastalarda daha yüksekti (p=0,002). Sonuç Artmış EYK, AF hastalarında KV başarı oranlarında azalma ile ilişkili bulunmuştur

Relationship Between Epicardial Fat Thickness and Cardioversion Success in Patients with Atrial Fibrillation

Objective Epicardial fat tissue is known to be arrhythmogenic. In this study we aimed to evaluate if this arrhythmogenic effect affects cardioversion (CV) success in patients with atrialfibrillation (AF). ( Sakarya Med J 2019, 9(1):125-130 )Materialsand MethodsWe studied100 AF patients treated with CV in order to restore sinus rhythm.Patients were divided into two groups; Group 1patients weresuccessfuly restored sinus rhythmand group 2 were failed to restoresinus rhythm. Demographic characteristics of study population, standard 2 dimensional Doppler and tissue Doppler echocardiographicfindings were recorded.Results There were 94 patients (59.5±14.1, years) in group 1 and 6 patients (59±8.7, years) in group 2. There were no differences between the two groups in terms of patientdemographics. Basic echocardiographic parameters suchas left atrial diameter,left ventricular diameter, septal thicness, ejection fraction, and left ventricular mass indexwere also similar between two groups. Epicardial fat thickness (EFT)was higher in group 2 patients (p=0.002).Conclusion Increased epicardial fat thickness found to be related with reduced CV success rates in the AF patients.
