📌 3 Key Takeaways

🎯
Objective & Hypothesis:Objective: The present study was an investigation of the relationship between fragmented QRS (fQRS) and left ventricular apical thrombus (LVAT) in patients presenting with first acute anterior myocardial infarction (MI).Methods: Consecutive 148 patients (mean age: 60.1±10.1 years; male: 75.6%) with first acute anterior MI who underwent primary percutaneous coronary intervention (PCI) were included.
📊
Key Findings & Data:Study population was divided into 2 groups based on presence of LVAT. fQRS was defined as presence of various RSR’ patterns, which included additional R wave or notching of R wave or S wave, and presence of more than 1 R in 2 contiguous leads corresponding to major coronary artery territory on 12-lead electrocardiogram.

Abstract

Objective: The present study was an investigation of the relationship between fragmented QRS (fQRS) and left ventricular apical thrombus (LVAT) in patients presenting with first acute anterior myocardial infarction (MI).Methods: Consecutive 148 patients (mean age: 60.1±10.1 years; male: 75.6%) with first acute anterior MI who underwent primary percutaneous coronary intervention (PCI) were included. Study population was divided into 2 groups based on presence of LVAT. fQRS was defined as presence of various RSR’ patterns, which included additional R wave or notching of R wave or S wave, and presence of more than 1 R in 2 contiguous leads corresponding to major coronary artery territory on 12-lead electrocardiogram. Patients with bundle branch block were excluded from the study.Results: Of these, 32 (21.6%) had LVAT. Patients with LVAT had higher prevalence of fQRS (53.1% vs. 22.4%; p

Özet

Amaç: Bu çalışmada, ilk akut ön duvar miyokart enfarktüsü ile başvuran hastalarda sol ventrikül apeksi trombüsü (LVAT) ile V4-V6 derivasyonlarında parçalanmış QRS (fQRS) varlığı arasında ilişki olup olmadığı araştırıldı.Yöntemler: İlk kez ön duvar miyokart enfarktüsü geçiren ve primer perkütan koroner girişim uygulanan ardışık 148 hasta (ortalama yaş: 60.1±10.1, erkek: %75.6) çalışmaya dahil edildi. Çalışma popülasyonu LVAT olup olmamasına göre iki gruba ayrıldı. FQRS, ek bir R dalgası veya R dalgası veya S dalgasının çentiklenmesi veya 12 derivasyonlu EKG üzerinde büyük koroner arter bölgesine karşılık gelen iki bitişik derivasyonda birden fazla R bulunması gibi çeşitli RSR paternlerinin varlığı olarak tanımlandı. Dal bloğuna sahip hastalar çalışma dışı bırakıldı.Bulgular: Hastaların 32'sinde (%21.6) LVAT vardı. Sol ventrikül apeksi trombüsü olan hastalar LVAT'siz hastalarla karşılaştırıldığında daha yüksek fQRS prevalansı (%53.1 ve %22.4, p
