  • Clinical Research Left Atrial Strain Assessed by Speckle Tracking Imaging Is Related to New-Onset Atrial Fibrillation After Coronary Artery Bypass Grafting

    Co-Authors: Ae-young Her, Jong-youn Kim, Yong Hoon Kim, Eui Young Choi, Pil-ki Min, Byoung-kwon Lee, Bum Kee Hong, Se-joong Rim, Hyuck Moon Kwon
    Abstract:

    Background: Left atrial (LA) dysfunction was recently proposed as an important factor in the development of postoperative atrial fibrillation (POAF). LA strain analysis by 2-dimensional (2D) speckle tracking imaging is emerging as a new tool to evaluate LA function. We aimed to evaluate the correlation of LA dysfunction assessed by 2D speckle tracking imaging with the occurrence of POAF after coronary artery bypass grafting (CABG). Methods: In this study, 53 patients (mean age 66 9 years) undergoing elective isolated CABG were enrolled. Conventional transthoracic echocardiography and 2D speckle tracking strain analysis were performed before surgery. POAF was detected with continuous Electrocardiography Monitoring throughout hospitalization (mean duration 17 10 days). Results: POAF occurred in 13 of 53 patients (24%). Patients with POAF were significantly older than patients with normal sinus rhythm after surgery (71 5v s 64 10 years, P 0.026). Compared with patients with normal sinus rhythm, patients with POAF had a significantly larger LA volume index (32.6 5.1 vs 27.3 7.2 mL/m 2 , P 0.018), lower value of LA global strain (25.4 10.4 vs 36.8 7.6%, P 0.001), and strain rate (1.2 0.6 vs 1.6 0.8 seconds, P 0.024). By multivariate logistic regression analysis, only LA global

POAF was detected with continuous Electrocardiography Monitoring throughout hospitalization (mean duration 17 ± 10 days). Results POAF occurred in 13 of 53 patients (24%). Patients with POAF were significantly older than patients with normal sinus rhythm after surgery (71 ± 5 vs 64 ± 10 years, P = 0.026). Compared with patients with normal sinus rhythm, patients with POAF had a significantly larger LA volume index (32.6 ± 5.1 vs 27.3 ± 7.2 mL/m 2 , P = 0.018), lower value of LA global strain (25.4 ± 10.4 vs 36.8 ± 7.6%, P = 0.001), and strain rate (1.2 ± 0.6 vs 1.6 ± 0.8 seconds, P = 0.024). By multivariate logistic regression analysis, only LA global strain (odds ratio, 1.12; 95% confidence interval, 1.00-1.24; P = 0.040) was an independent predictor of POAF after CABG. Conclusions Preoperative LA global strain measured by 2D speckle tracking strain analysis is associated with the development of POAF after CABG.

  • The Role of Pacing in Elderly Patients with Unexplained Syncope
    Current Cardiovascular Risk Reports, 2019
    Co-Authors: Justin Z. Lee, Siva K. Mulpuru, Win Kuang Shen
    Abstract:

    To discuss the role of pacing in elderly patients with unexplained syncope. In patients with recurrent syncope with suspected reflex mechanism, the decision of pacemaker implantation can be guided by a standardized algorithm which includes carotid sinus massage, tilt-table testing, and implantable loop recorder. Cardiac pacing may reduce recurrent syncope in cardioinhibitory carotid sinus syndrome. In select elderly patients with recurrent cardioinhibitory vasovagal syncope, cardiac pacing may also reduce syncope recurrence. There is no role of cardiac pacing in patients with without a cardioinhibitory response. There is increasing evidence that closed loop stimulation reduces the recurrence of cardioinhibitory vasovagal syncope. In patients with syncope and a positive electrophysiology study consistent with sinoatrial or conduction system disease, cardiac pacing has been shown to reduce recurrent syncope. Cardiac pacing is also effective in reducing recurrent syncope when high-grade atrioventricular block is documented on Electrocardiography Monitoring. In elderly patients with unexplained syncope and bundle branch block on ECG, diagnostic algorithm should be followed according to guidelines; empirical pacing is generally not recommended. Permanent pacemaker implantation may be effective to reduce recurrent syncope in select groups of elderly patients. It is important to consider additional investigations to evaluate elderly patients with unexplained syncope. The results of these testing would guide the decision on permanent pacemaker implantation.
