Background: Early postoperative atrial fibrillation (POAF) has been reported following coronary artery bypass graft (CABG).This study aims to detect the coronary angiographic predictors of POAF. Methods: This is a prospective study that included 100 patients with CAD and sinus rhythm scheduled for CABG. Exclusion included abnormal rhythm, impaired LV systolic function, congenital heart diseases, concomitant valve replacement or previous cardiac operation. Results: Patients were classified into: group I included 22 patients (22%) who developed POAF and Group II: included 78 patients (78%) patients who remained in sinus rhythm. Group I were significantly older than group II (mean age of 65 ± 6.25 in group I versus 54.5 ± 6.7 in group II, p value = 0.001).Left main coronary artery (LM) involvement was higher in group I (50%) versus group II (23.07%), p value = 0.014. There was no significant difference between the two groups regarding number of grafts and echocardiographic data. Conclusion: In our study, patients with advanced age, and those with left main lesion had a higher rate of POAF.

“…Only recently, the LA longitudinal strain (change in length of the atrial walls during the cardiac cycle) emerged as a promising measure of the LA mechanical function [9,10]. Several studies suggested independent and superior to other morphological LA measures predictive role of the LA strain for the occurrence of paroxysmal AF in patients with ischemic stroke, hypertrophic cardiomyopathy, chemotherapy, HFpEF, and after coronary artery bypass grafting [11][12][13][14][15]. Moreover, LA strain was shown to independently predict incident HFpEF and to improve diastolic dysfunction classification [16][17][18][19].…”

The Influence of Surgical Weight Reduction on Left Atrial Strain

Background Obesity increases and surgical weight reduction decreases the risk of atrial fibrillation (AF) and heart failure (HF). We hypothesized that surgically induced weight loss may favorably affect left atrial (LA) mechanical function measured by longitudinal strain, which has recently emerged as an independent imaging biomarker of increased AF and HF risk. Methods We retrospectively evaluated echocardiograms performed before and 12.2 ± 2.2 months after bariatric surgery in 65 patients with severe obesity (mean age 39 [36; 47] years, 72% of females) with no known cardiac disease or arrhythmia. The LA mechanical function was measured by the longitudinal strain using the semi-automatic speckle tracking method. Results After surgery, body mass index decreased from 43.72 ± 4.34 to 30.04 ± 4.33 kg/m2. We observed a significant improvement in all components of the LA strain. LA reservoir strain (LASR) and LA conduit strain (LASCD) significantly increased (35.7% vs 38.95%, p = 0.0005 and − 19.6% vs − 24.4%, p < 0.0001) and LA contraction strain (LASCT) significantly decreased (− 16% vs − 14%, p = 0.0075). There was a significant correlation between an increase in LASR and LASCD and the improvement in parameters of left ventricular diastolic and longitudinal systolic function (increase in E’ and MAPSE). Another significant correlation was identified between the decrease in LASCT and an improvement in LA function (decrease in A’). Conclusions The left atrial mechanical function improves after bariatric surgery. It is partially explained by the beneficial effect of weight reduction on the left ventricular diastolic and longitudinal systolic function. This effect may contribute to decreased risk of AF and HF after bariatric surgery. Graphical abstract

“…The association of indexed volume of left atrium with ischemic stroke is controversial (Baturova et al, 2016;Yoon et al, 2013). On the other hand, the analysis of AEF, especially with longitudinal strain, shows a direct relationship with paroxysmal atrial fibrillation (Rasmussen et al, 2019). In fact, we found a reduction in AEF values in the cardioembolic group, which portrays a slowing in atrial emptying.…”

Introduction: Studies show that p-wave dispersion and left atrial ejection fraction are predictors of cardiovascular events. Purpose: To verify the association of p-wave dispersion and left atrial ejection fraction with cardioembolic ischemic stroke. Methods: This is an observational, cross-sectional, case-control study with 61 patients, mean age of 65.6, with sinus rhythm ischemic stroke who underwent clinical evaluation with CHA2DS2-VASc score, electrocardiogram, echocardiogram and ultrasonography with Doppler of both carotid and vertebral arteries. The groups were divided into cardioembolic (cases) and non-cardioembolic (controls). The p-wave dispersion was obtained with a 12-lead electrocardiographic tracing at 50 mm/s by subtracting the largest p-wave by the smallest one. Left atrial ejection fraction was obtained using the modified biplane Simpson method. This study was approved by the UERN Research Ethics Committee (# 2,536,483). Results: Mean values for p-wave dispersion were 62.5 ms for cases and 49 ms for controls (p = 0.025). For left atrial ejection fraction, the cases presented a mean of 42.9% and the controls a mean of 55.8% (p = 0.003). For the CHA2DS2-VASc score, the mean values were 3.6 and 3.1 for cases and controls, respectively (p = 0.35). Cardiovascular risk factors showed similar distribution in both groups. Conclusion: p-wave dispersion and left atrial ejection fraction were associated with the cardioembolic patients with sinus rhythm that have gone through ischemic stroke.
