🎯
Objective & Hypothesis:Objective: This study was prospectively designed to evaluate the relationship between the mitral A wave acceleration slope (AWA-slope) and the left atrial ejection fraction (LA-EF) after the restoration of sinus rhythm in patients with atrial fibrillation (AF), and also to evaluate the change in the AWA-slope between the sequent second day and first month.
📊
Key Findings & Data:Methods: Twenty-nine patients (16 female, mean age 56±13 years) with unknown cause of AF (except for age) converted to sinus rhythm within the first 48 hours were included into the study.

Abstract

Objective: This study was prospectively designed to evaluate the relationship between the mitral A wave acceleration slope (AWA-slope) and the left atrial ejection fraction (LA-EF) after the restoration of sinus rhythm in patients with atrial fibrillation (AF), and also to evaluate the change in the AWA-slope between the sequent second day and first month. Methods: Twenty-nine patients (16 female, mean age 56±13 years) with unknown cause of AF (except for age) converted to sinus rhythm within the first 48 hours were included into the study. A transthoracic echocardiography was performed in all patients on the second day and the first month after restoration of the sinus rhythm. The paired Student’s t test was used in comparisons of the continuous variables. The simple and multiple correlations of the LA-EF were evaluated by the simple and multiple linear regression analyses, respectively. Results: Left atrial ejection fraction (42±17 vs 51±19%, p=0.03) and AWA-slope (950±337 vs 1087±351 cm/sec2, p=0.021) obtained after the first month were greater than on the second day. A significant correlation between LA-EF and AWA-slope was observed both on the second day (r=0.76, p

Özet

Amaç: Bu çalışma, atriyal fibrilasyonlu (AF) hastalarda sinüs ritmi elde edildikten sonra mitral A dalga akselerasyon eğimi (ADA-eğimi) ile sol atriyal ejeksiyon fraksiyonu (SA-EF) arasındaki ilişkiyi ve 2. gün ile 1. ay arasında ADA-eğimindeki değişimi değerlendirmek için prospektif olarak düzenlendi. Yöntemler: Yaş haricinde bir sebep bulunamayan ve ilk 48 saat içinde sinus ritmine döndürülen AF’li 16’sı bayan 29 hasta (16 bayan, ortalama yaş 56±13 yıl) çalışmaya alındı. Transtorasik ekokardiyografi sinüs ritmi elde edildikten sonraki 2. gün ve 1. ayda bütün hastalara uygulandı. Sayısal değişkenlerin karşılaştırılmasında eşlenmiş Student-t testi kullanıldı. Sol atriyal ejeksiyon fraksiyonunun tekli ve çoklu korelasyonları sırasıyla basit ve çoklu lineer regresyon analizleri ile değerlendirildi. Bulgular: Sol atriyal ejeksiyon fraksiyonu (%51±19’a karşı %42±17, p=0.03) ve ADA-eğimi (1087±351’e karşı 950±337cm/sn2, p=0.021) 1. ayda 2. güne göre daha büyük idi. Hem 2. günde ve hem de 1. ayda SA-EF ile ADA-eğimi arasında anlamlı korelasyon gözlendi (sırasıyla r=0.76, p
