Comparison of right ventricular functions according to infarct localization using advanced echocardiographic methods in myocardial infarction with ST elevation

Abstract

Objectives: In this study, we aimed to compare the effects of infarct localization in patients with ST Elevated Myocardial Infarction (STEMI) on the right ventricular (RV) functions by using advanced echocardiographic methods. Materials and methods: A total of 89 patients with STEMI were included into the study and patients were divided to three groups as anterior, isolated-inferior and inferior+RV MI groups. In addition to standard echocardiographic mesurements, RV tissue doppler, RV Ejection Fraction (RVEF), Myocardial performance index (MPI) and TAPSE measurements of all patients were performed between 24-72 hours after the event. Results: Compared to groups, RV functions in inferior MI with RV involvement group were deteriorated. Tricuspid annular plane systolic excursion (TAPSE) value for the inferior MI with RV involvement (19±1mm) group were lower than those for Inferior MI group without RV involvement (23±1mm) and anterior MI (23±1mm) (p

ST elevasyonlu miyokard infarktüsünde infarkt lokalizasyonuna göre sağ ventrikül fonksiyonlarının ileri ekokardiografik metotlarla karşılaştırılması

Abstract

Amaç: Bu çalışmada amacımız ST elevasyonlu miyokard infarktüsü (STEMİ) hastalarında ileri ekokardiyografik metodlar kullanarak infarkt lokalizasyonunun sağ ventrikül fonksiyonları üzerindeki etkilerini karşılaştırmaktır.Gereç ve yöntem: Çalışmaya toplam 89 STEMİ hastası alındı. Hastalar infarkt lokalizasyonuna göre anteriyor, izole inferior ve inferior+sağ ventrikül miyokard infarktüsü (Mİ) olmak üzere üç gruba ayrıldı. Tüm hastalara ilk 2472 saat içinde ekokardiografik inceleme yapılarak rutin ekokardiografik ölçümlere ek olarak sağ ventrikül doku Doppler, sağ ventrikül ejeksiyon fraksiyonu (SağVEF), miyokard performans indeksi (MPİ) ve Triküspit Anüler Düzlem Sistolik Hareketlerinin (TAPSE) ölçümleri alındı.Bulgular: Gruplar karşılaştırıldığında, sağ ventrikül tutulumu olan inferior Mİ grubunda sağ ventrikül fonksiyonlarının bozulmuş olduğu görüldü. TAPSE, sağ ventrikül tutulumu olan inferior MI (19±1mm) grubunda izole inferior MI (23±1mm) ve anterior MI (23±1mm) gruplarına göre daha düşüktü (p
