Abstract

Abstract
Background: Patients who develop new-onset atrial fibrillation (AF) after ST segment elevation myocardial infarction (STEMI) demonstrate an expanded hazard for unfavorable occasions and mortality during follow-up, so we hope to predict it. A new noninvasive echocardiographic method has been approved for AF prediction. It involves estimation of inter-atrial dyssnchrony time utilizing tissue Doppler imaging and was found to be independent predictor for AF [1].
Aim: To study role of intra and inter-atrial dyssynchrony which (calculated by tissue Doppler) in prediction of atrial fibrillation in STEMI patients during hospitalization.
Patients and methods: STEMI patients were subjected to tissue Doppler using Trans Thoracic echocardiography to detect intra and inter-atrial dyssnchrony and detect their association with developing new onset AF.
Results: There was a statistically significant difference between both AF and non AF groups regarding hypertension, p wave dispersion, (PA mitral), (PA septal), (PA tricuspid), left atrial dyssnchrony, inter atrial dyssnchrony and type of revascularization. There was no statistically significant difference between the two groups regarding age, sex, risk factors as Diabetes mellitus (DM) ,Family history to coronary artery disease (CAD), smoking and dyslipidemia, duration of chest pain ,lab parameters including troponin, , C-reactive protein (CRP),HbA1C.
Conclusion: Inter-atrial dyssynchrony and left atrial dyssynchrony can be used as independent predictor for AF development in Anterior STEMI patients during their hospitalization.
