Key result
Inter-atrial and left atrial dyssynchrony measured by tissue Doppler were identified as independent predictors for new-onset atrial fibrillation in anterior STEMI patients during hospitalization.
Why the study?
Patients who develop new-onset AF after STEMI have an increased risk of adverse events and mortality, motivating noninvasive prediction using tissue Doppler imaging.
Does tissue Doppler estimation of intra and inter-atrial dyssynchrony predict in-hospital atrial fibrillation in patients with STEMI?
Observational
Does tissue Doppler estimation of intra and inter-atrial dyssynchrony predict in-hospital atrial fibrillation in patients with STEMI?
Inter-atrial and left atrial dyssynchrony measured by tissue Doppler echocardiography can independently predict the development of new-onset atrial fibrillation during hospitalization in patients with anterior STEMI.
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.

Aawar et al. (2019) conducted an observational in ST segment elevation myocardial infarction (STEMI). Inter- and intra-atrial dyssynchrony vs. Absence of dyssynchrony was evaluated on New-onset atrial fibrillation. Inter-atrial and left atrial dyssynchrony measured by tissue Doppler were identified as independent predictors for new-onset atrial fibrillation in anterior STEMI patients during hospitalization.
