Left atrial volume predicts cardiovascular events in patients originally diagnosed with lone atrial fibrillation: three-decade follow-up

Abstract Aims Atrial fibrillation (AF) is a progressive disease, but identifying patients at risk for AF progression is challenging. We aimed to identify factors associated with AF progression. Methods and results Atrial fibrillation progression was assessed in 392 patients with recent-onset paroxysmal or persistent AF included in the prospective, observational, multicentre identification of a risk profile to guide atrial fibrillation (AF-RISK) study. Progression of AF was assessed by Holter monitoring and 2-week event recorder at baseline and 1-year follow-up. AF progression was defined as: (i) doubling in AF burden at 1 year compared to baseline with a minimum AF burden of 10% in paroxysmal AF; or (ii) transition from paroxysmal to persistent or permanent AF; or (iii) persistent to permanent AF. Age was 60 ± 11 years, 62% were men, and 83% had paroxysmal AF. At 1 year, 52 (13%) had AF progression (11% in paroxysmal; 26% in persistent AF). Multivariable logistic regression showed that left atrial volume [odds ratio (OR) per 10 mL 1.251, 95% confidence interval (CI) 1.078–1.450; P < 0.001], N-terminal pro-B-type natriuretic peptide (NT-proBNP; OR per standard deviation increase 1.583, 95% CI 1.099–2.281; P = 0.014), and plasminogen activator inhibitor-1 (PAI-1; OR per standard deviation increase 0.660, 95% CI 0.472–0.921; P = 0.015) were associated with AF progression. In an additional follow-up of 1.9 (0.9–3.3) years patients with AF progression developed more cardiovascular events and all-cause mortality (12.4%/year vs. 2.3%/year, P < 0.001). Conclusion Atrial fibrillation progression occurred in 13% of patients with recent-onset AF during 1-year follow-up. Left atrial volume, NT-proBNP, and PAI-1 were associated with AF progression. Patients with AF progression had a higher event rate. Trial registration number Clinicaltrials.gov NCT01510210.

AbstractOBJECTIVESPostoperative atrial fibrillation (POAF) is a common complication following cardiac surgery. However, knowledge on the rate of long-term atrial fibrillation (LTAF) after POAF remains unclear. We investigated predictors of POAF in patients with aortic stenosis undergoing surgical aortic valve replacement, and assessed the rate of LTAF during follow-up.METHODSWe prospectively included 96 adult patients with severe aortic stenosis undergoing surgical aortic valve replacement. Patients with previous atrial fibrillation (AF) were excluded. Patients underwent echocardiography, cardiac computed tomography and magnetic resonance imaging immediately prior to surgery. Surgical aortic clamp time and postoperative C-reactive protein (CRP) were documented. POAF was defined as AF recorded within 7 days of surgery. Through chart review, patients were followed up for documented episodes of LTAF occurring more than 7 days after surgery.RESULTSPOAF occurred in 51 patients (53%). It was associated with larger preoperative echocardiographic left atrial volume index (44 ± 12 vs 37 ± 8 ml/m2, P = 0.004), longer aortic clamp time [80 (70–102) vs 72 (62–65) min, P = 0.04] and higher CRP on first postoperative day [80 (64–87) vs 65 (44–83) mg/l, P = 0.001]. Multivariable logistic regression revealed that left atrial volume index [odds ratio (OR) 1.07, 95% confidence interval (CI) 1.02–1.13; P = 0.005] and postoperative CRP (OR 1.03, 95% CI 1.01–1.05; P = 0.006) were the only independent predictors of POAF. During 695 days (25th–75th percentile: 498–859 days) of follow-up, LTAF occurred in 11 patients of whom 10 were in the POAF group (hazard ratio 9.4, 95% CI 1.2–74; P = 0.03).CONCLUSIONSPOAF is predicted by left atrial volume index and postoperative CRP. Patients with POAF have a 9-fold increase risk of developing symptomatic LTAF during follow-up.Clinical trial registration numberClinicalTrials.gov (NCT02316587).

Abstract Background and Aims Atrial fibrillation (AF) and chronic kidney disease (CKD) are common and often co-existing conditions. However, little is known on the prevalence and incidence of AF in patients with CKD stage 4-5. Method We prospectively recruited 210 consecutive non-dialysis patients with CKD stage 4-5 between 2013 and 2017. Follow-up data on AF occurrence as well as baseline medical history, laboratory tests and echocardiography were collected. Results At baseline, mean age was 62 years, 73/210 (34.8%) of the participants were female, mean estimated glomerular filtration rate was 12.8ml/min and 41/210 (19.5%) patients had a prior diagnosis of AF. After median follow-up of 46 [IQR 27] months, new-onset AF was detected in 33/169 (19.5%) patients (69.9 events/1000 person-years). Overall, 22/33 (66.7%) of patients with new-onset AF were identified with a triggering condition, most commonly severe infection or surgery, and 21/33 (63.6%) were receiving renal replacement therapy (dialysis or acquired kidney transplant) at the time of AF detection, respectively. In Cox proportional hazard model age >60 years (HR 4.27, CI95% 1.57-11.64, p<0.01), elevated troponin T (TnT) >50ng/l (HR 3.61, CI95% 1.55-8.37, p<0.01) and left atrial volume index (LAVI) >30ml/m2 (HR 4.82, CI95% 1.11-21.00, p=0.04) independently predicted the occurrence of new-onset AF. Furthermore, the predictive effect of the covariates was cumulative (Figure 1). Conclusion The incidence rate of AF was remarkably high in this prospective study on patients with CKD stage 4-5. Elevated TnT and increased LAVI are associated with the occurrence of new-onset AF in patients with severe CKD.
