Abstract

Objective: Fragmented QRS complexes (fQRS) are defined as various RSR′ patterns in 2 contiguous leads corresponding to a major coronary artery territory. Although the reason of association between fQRS and cardiac events was documented as cardiac fibrosis, the predictive role of fQRS was not studied for postoperative atrial fibrillation (POAF) which is a frequent and serious complication in patients undergoing isolated coronary artery bypass graft (CABG) surgery. Therefore, this issue was investigated in the present study. Methods: The current study has a prospective observational design. Two hundred and seventy two eligible patients who underwent isolated CABG surgery were enrolled consecutively. The patients were divided in two groups with post-op atrial fibrillation (AF) and non-AF. The occurrence of new-onset AF following CABG and the relationship with fQRS were searched. The logistic regression analysis was used to determine independent predictors for POAF. The sensitivity and specificity of study variables in predicting POAF were calculated using a receiver-operating characteristic curve (ROC). Results: POAF occurred in 62 of 272 patients (22.8%). Patients with POAF were generally older (p

Özet

Amaç: Fragmente olmuş QRS kompleksleri (fQRS) bir majör koroner arter bölgesine karşılık gelen 2 ardışık derivasyonda çeşitli RSR' paternleri olarak tanımlanılmaktadır. FQRS ve kardiyak olaylar arasında miyokardiyal fibrozisin sebepsel ilişkisi ortaya konulmuş olsa da, izole koroner arter baypass greftleme cerrahisi (KABG) yapılan hastalarda sık ve ciddi bir komplikasyon olan postoperatif atriyal fibrilasyon (POAF) için fQRSin öngörücü rolü şimdiye kadar araştırılmamıştır. Bundan dolayı bu ilişki çalışmamızda incelendi. Yöntemler: Çalışma gözlemsel yapılı olarak düzenlendi. İzole KABG cerrahisine giden, çalışma kriterlerine uygun 272 hasta ardışık olarak çalışmaya dahil edildi. Hastalar postoperatif atriyal fibrilasyon (AF)u olan ve olmayan olmak üzere iki gruba ayrıldı. KABG cerrahisini takiben yeni başlangıçlı AF gelişimi ve fQRS ile ilişkisi araştırıldı. Lojistik regresyon analizi POAFyi öngören bağımsız değişkenlerin belirlenilmesinde kullanıldı. Çalışma parametrelerinin POAFyi öngörmedeki duyarlılık ve özgüllükleri ROC eğrisi altında kalan alan ile hesaplandı. Bulgular: POAF 272 hastanın 62sinde (%22.8) gelişti. POAFlı hastalar AFsiz hastalar ile karşılaştırıldığında, genellikle daha yaşlı (p
