Predictive value of early recurrence and delayed cure after catheter ablation for patients with chronic atrial fibrillation.

BACKGROUND: Radiofrequency catheter ablation (RFCA) for curing atrial fibrillation (AF) is often followed by early recurrence and delayed cure, so the present study investigate the predictive factors this in patients with chronic AF. METHODS AND RESULTS: Ninety-two consecutive patients (70 males; mean age, 58.7+/-6.4 years) with chronic AF who underwent RFCA for treatment of symptomatic AF were enrolled. Early recurrence of AF (ERAF) occurred in 45 patients after ablation. Not achieving AF termination could predict ERAF (odds ratio (OR) 0.95; 95% confidence interval (CI) 0.84-1.13; p=0.02) in multivariate analysis. During a follow-up of 12+/-11 (range, 5-25) months, delayed cure occurred in 35.6% (16/45) of the patients with ERAF. Left atrial size and AF termination during ablation were related to delayed cure. AF termination was the only independent predictive factor for delayed cure (OR 1.47; 95% CI 1.05-1.87; p=0.02). CONCLUSION: Not achieving AF termination is the only independent predictor of ERAF. Among patients with ERAF, those with a smaller left atrium and AF termination have a higher probability of delayed cure. AF termination can independently predict delayed cure. These results emphasize the importance of AF termination during ablation for patients with chronic AF.

Usefulness of left ventricular diastolic dysfunction assessed by pulsed tissue Doppler imaging as a predictor of atrial fibrillation recurrence after successful electrical cardioversion

The impact of left ventricular (LV) diastolic dysfunction on risk of atrial fibrillation (AF) recurrence is still unknown. The aim of this study was to assess the role of LV diastolic dysfunction in predicting AF recurrence after successful electrical cardioversion in patients with nonvalvular AF. In 51 patients with a first episode of nonvalvular AF undergoing successful electrical cardioversion, tissue Doppler echocardiography was performed to measure peak early diastolic mitral annulus velocity (E(m)) and the ratio of mitral inflow to mitral annulus velocity at end-diastole (E/E(m)). Clinical end points were recurrent persistent AF at 2-week follow-up (early AF recurrence [ERAF]) and at 1-year follow-up (including ERAF and late AF recurrence). Seventeen patients showed evidence of ERAF, whereas late AF recurrence occurred in another 5 patients. In time-independent analysis E/E(m) (odds ratio [OR] 1.746, p = 0.0084) and indexed LV end-systolic volume (OR 1.083, p = 0.040) were independent predictors of ERAF. Based on a logistic model risk of ERAF was 25% for an E/E(m) of 5.6 but increased to 50% for an E/E(m) of 8.1 and to 75% for an E/E(m) of 10.5. In time-dependent analysis E/E(m) emerged as the only predictor of ERAF (OR 1.757, p = 0.0078). E/E(m) also independently predicted risk of recurrence at 1 year in time-independent (OR 1.757, p = 0.0078) and time-dependent (OR 1.319, p = 0.0003) analyses. In conclusion LV diastolic dysfunction independently predicts AF recurrence in patients with nonvalvular AF undergoing successful electrical cardioversion.     

Predictive risk factors for recurrent atrial fibrillation after modified endoscopic ablation: A 2‐year follow‐up

Background

Our previous study reported a modified endoscopic procedure for nonvalvular atrial fibrillation (AF) that requires only 3 ports in the left chest wall.

Hypothesis

Certain preoperative variables might be predictive risk factors for AF recurrence among patients who underwent this procedure.

Methods

From October 2010 to April 2014, 114 patients with either paroxysmal AF (PAF) or nonparoxysmal AF (non‐PAF) underwent the procedure and completed postoperative cardiac‐rhythm measurement via electrocardiography and Holter monitoring. Univariate and multivariate analyses of the possible AF‐related risk factors were conducted.

Results

During 2‐year follow‐up, 99 of 114 patients (86.8%) were free from atrial tachyarrhythmia. Results from univariate analyses showed that AF duration, left atrial diameter (LAD), left atrial minimum volume, left atrial empty fraction, left atrial expansion index, and left atrial active empty fraction (LAAEF) were significantly associated with postoperative AF recurrence. Results from multivariate analyses showed that AF duration (odds ratio [OR]: 1.194, 95% CI: 1.063‐1.340, P = 0.003), LAD (OR: 1.101, 95% CI: 1.005‐1.205, P = 0.039), and LAAEF (OR: 0.490, 95% CI: 0.277‐0.865, P = 0.014) were independent risk factors. There was no difference in AF recurrence between patients with PAF and non‐PAF (P = 0.250).

Conclusions

Our 2‐year follow‐up study suggested that low LAAEF, long AF duration, and large LAD might be potential predictive risk factors for AF recurrence. Patients with PAF and non‐PAF had a similar AF recurrence rate after modified endoscopic ablation.     

Predictors of very late recurrence of atrial fibrillation after circumferential pulmonary vein ablation

BACKGROUND: Early recurrence of atrial fibrillation (ERAF) after catheter ablation is common and has been thoroughly studied. However, very late recurrence of atrial fibrillation (VLRAF) is rarely researched, and its characteristics have not been determined. HYPOTHESIS: The aim of this study was to investigate the clinical characteristics of VLRAF after circumferential pulmonary vein ablation (CPVA), and to identify the risk factors for VLRAF. METHODS: We retrospectively studied 259 consecutive patients with atrial fibrillation (AF) who were referred for CPVA. Clinical variables were investigated and predictors of VLRAF were identified. RESULTS: A total of 249 patients were enrolled in this study. After a mean follow-up of 18.2 +/- 4.4 mo, 14 patients (5.6%) had VLRAF. Patients with VLRAF were more likely than those without recurrence to have ERAF (78.6% versus 17.8%, p = 0.000) and persistent AF (50.0% versus 13.0%, p = 0.000), but were less likely to achieve pulmonary vein (PV) isolation (78.6% versus 97.6%, p = 0.000). Bivariate analysis demonstrated that ERAF (odds ratio [OR] 8.148, 95% confidence interval [CI] 2.197-30.222; p = 0.002), persistent AF (OR 8.853, 95% CI 1.773-16.155; p = 0.003), and lack of PV isolation (OR 7.530, 95% CI 1.792-33.122; p = 0.006) were related to VLRAF. Multivariate logistic regression analysis only identified ERAF as a predictor of VLRAF after CPVA (OR 7.461, 95% CI 1.696-24.836; p = 0.006). CONCLUSIONS: Very late recurrence of AF is uncommon after CPVA. That occurs more commonly in patients with ERAF.

Electrocardiographic left ventricular hypertrophy predicts recurrence of atrial arrhythmias after catheter ablation of paroxysmal atrial fibrillation

Background

Left ventricular hypertrophy (LVH) is an independent predictor of new‐onset atrial fibrillation. Whether LVH can predict the recurrence of arrhythmia after radiofrequency catheter ablation (RFCA) in patients with paroxysmal atrial fibrillation (PAF) remains unclear.

Hypothesis

PAF patients with baseline‐electrocardiographic LVH has a higher recurrence rate after RFCA procedure compared with those without LVH.

Methods

A total of 436 patients with PAF undergoing first RFCA were consecutively enrolled and clustered into 2 groups based on electrocardiogram (ECG) findings: non‐ECG LVH (218 patients) and ECG LVH (218 patients). LVH was characterized by the Romhilt‐Estes point score system; the score ≥5points were defined as LVH.

Results

At 42 months' (interquartile range, 18.0–60.0 months) follow‐up after RFCA, 151 (69.3%) patients in the non‐ECG LVH group and 108 (49.5%) patients in the ECG LVH group maintained sinus rhythm without using antiarrhythmic drugs (P < 0.001). Patients with ECG LVH tended to experience a much higher prevalence of stroke and recurrence of atrial arrhythmia episodes compared with those without ECG LVH (log‐rank P < 0.001). Multivariate analysis found the presence of ECG LVH and left atrial diameter to be independent risk factors for recurrence after adjusting for confounding factors.

Conclusions

The presence of ECG LVH was a strong and independent predictor of recurrence in patients with PAF following RFCA.     

Predictors of early recurrence and delayed cure after segmental pulmonary vein isolation for paroxysmal atrial fibrillation without structural heart disease

Background Early recurrence of atrial fibrillation (ERAF) and delayed cure are commonly observed after atrial fibrillation (AF) ablation. The purpose of this study was to determine the predictors of ERAF and delayed cure after a single pulmonary vein isolation (PVI) performed in paroxysmal AF patients without structural heart disease.Methods and results In 108 consecutive patients (93 men, 15 women; mean age 51 ± 8 years) with paroxysmal AF and no structural heart disease, segmental PVI guided by a Lasso catheter was performed. Forty-one percent (44/108) AF patients had ERAF after a single PVI. Univariate analysis revealed that left atrial diameter (p = 0.004), age (p = 0.024) and P-wave dispersion (p = 0.045) were significantly related to ERAF. Logistic regression analysis revealed that left atrial enlargement was the only independent predictor of ERAF (odds ratio [OR] 1.17; 95% confidence interval [CI] 1.04–1.30, p = 0.006). Delayed cure occurred in 32% (14/44) patients with ERAF. P-wave dispersion (p = 0.001), left atrial diameter (p = 0.008) were significantly related to delayed cure. P-wave dispersion was the only independent predictive factor of delayed cure (OR 0.91; 95% CI 0.85–0.97, p = 0.004).Conclusions Elderly patients with left atrial enlargement and a high dispersion of P wave are susceptible to ERAF after a single PVI. Left atrial enlargement is the only independent predictor of ERAF. Among patients with ERAF, those with less P-wave dispersion and less left atrial diameter have a higher probability of delayed cure. P-wave dispersion can independently predict delayed cure.This study was supported by National Natural Science Foundation of China. (NSFC No.30470704). There is not any potential conflict of interest.     

急性冠状动脉综合征患者血清中性粒细胞/淋巴细胞比值、血小板/淋巴细胞比值水平对冠状动脉病变程度及院内主要不良心血管事件的评估价值

目的探讨急性冠状动脉综合征(ACS)患者中性粒细胞/淋巴细胞比值(NLR)、血小板/淋巴细胞比值(PLR)与冠状动脉狭窄程度及院内主要不良心血管事件(MACE)发生的关系。方法收集2018年4月至2020年4月于新疆医科大学第一附属医院初次行冠状动脉造影ACS患者(426例)的临床基本资料、实验室参数,根据住院MACE情况,将纳入的患者分为MACE组(104例)和无MACE组(322例)。根据Gensini评分的三分位数,将患者分为三组:低Gensini组(≤34分,143例),中Gensini组(34~58分,142例),高Gensini组(>58分,141例),使用t检验、方差分析、卡方检验、非参数Mann-Whitney U检验、Kruskal-Wallish H检验、logistic回归分析和受试者工作特性曲线等统计方法对数据进行分析。结果MACE组NLR[4.48(2.42,7.47)比2.82(1.79,4.70),P<0.001]和PLR[133.21(92.88,190.25)比101.03(75.33,134.01),P<0.001]显著高于无MACE组,差异有统计学意义。在基于Gensini评分分组的三组中,低Gensini组、中Gensini组、高Gensini组NLR[3.59(1.56,3.58)比3.47(1.94,5.73)比3.71(2.13,6.21),P<0.001]、PLR[93.98(66.03,127.94)比110.90(88.26,140.79)比120.37(84.58,174.54),P<0.001]比较,差异均有统计学意义。logistic回归分析显示,NLR(OR 1.189,95%CI 1.003~1.409,P=0.046;OR 1.102,95%CI 1.005~1.208,P=0.039)、PLR(OR 1.008,95%CI 1.002~1.014,P=0.021;OR 1.004,95%CI 1.002~1.009,P=0.042)是院内MACE和高Gensini评分的独立危险因素。NLR预测院内MACE发生的截断值为4.516,敏感度为50.00%,特异度为74.53%,曲线下面积(AUC)为0.633(95%CI 0.585~0.679,P<0.001);PLR预测院内MACE发生的截断值为153.103,敏感度为45.19%,特异度为84.78%,AUC为0.666(95%CI 0.619~0.711,P<0.001)。NLR预测高Gensini评分(>58分)的截断值为3.802,敏感度为49.62%,特异度为66.44%(AUC=0.600,95%CI 0.552~0.647,P<0.001);PLR预测高Gensini评分的截断值为153.543,敏感度为37.40%,特异度为84.75%(AUC=0.616,95%CI 0.567~0.662,P<0.001)。结论NLR、PLR作为一种新的炎症标志物,与ACS患者院内MACE的发生和冠状动脉狭窄的严重程度有显著的独立相关性。NLR、PLR作为一种容易获得且价格便宜的炎症指标,可作为有效的炎症标志物广泛应用于鉴别高危患者,从而有助于指导个体化治疗以改善ACS预后。
