“…A study conducted by Chao et al evaluated whether atrial electromechanical interval (PA-PDI) was a significant predictor of stroke after successful catheter ablation of AF. They revealed that the PA-PDI interval was a useful parameter which may identify patients with high risk of stroke after ablation of AF [31]. In our study, we did not intend to evaluate predictive value of left atrial electromechanical function on future stroke development.…”

“…In addition, we suggest that AEMD times, when combined with the CHA2DS2‐VASc scoring system might increase the predictive value of this scoring system to predict the risk of ischemic stroke. As a matter of fact, Chao et al . in their study detected that lengthened PA‐PDI time may be an independent predictor of stroke and could increase the predictive power of CHA2DS2‐VASc score to predict the risk of stroke when combined with CHA2DS2‐VASc score.…”

“…A cut-off value of 150 ms, which was identified by the ROC curve, had 100% sensitivity and 85.7% specificity in predicting stroke following ablation. According to these results, the continuation of warfarin treatment was recommended following AF ablation in patients with the PA-PDI interval equal to or >150 ms (26). …”

Objective:This study aimed to evaluate the association between the history of stroke/transient ischemic attack (TIA) and inter- and intra-atrial electromechanical delay (EMD) in patients with paroxysmal atrial fibrillation (PAF).Methods:Patients diagnosed with PAF were included in this retrospective study. Patients who had a history of stroke or TIA were defined as the symptomatic group, whereas those who did not have such a history were defined as the asymptomatic group. On the basis of the transthoracic echocardiographic records, atrial electromechanical coupling (time interval from the onset of the P wave on the surface electrocardiogram to the beginning of the A’ wave interval with tissue Doppler echocardiography) and intra- and interatrial EMD were measured.Results:In this study, 160 patients were included, 52 of whom were symptomatic. While the intra-left atrial EMD was 68.2±6.1 ms in the symptomatic group, it was found to be 50.8±6.5 ms in the asymptomatic group (p<0.001). Interatrial EMD was 91.3±5.0 ms in the symptomatic group, whereas it was 71.5±7.0 ms in the asymptomatic group (p<0.001). In multiple logistic regression analysis, intra-left atrial [odds ratio (OR): 1.417, 95% confidence interval (CI): 1.193–1.684, p<0.001] and interatrial EMDs (OR:1.398, 95% CI: 1.177–1.661, p<0.001) were found to be independently associated with the presence of stroke/TIA.Conclusion:Prolonged inter- and intra-left atrial EMDs in patients with PAF is associated with stroke/TIA. Evaluating this parameter in addition to the CHA2DS2-VASc score in patients with PAF may be helpful in identifying patients who are at a high risk of stroke/TIA. (Anatol J Cardiol 2016; 16: 572-8)
