    Abstract: Prior studies have reported conflicting results on digoxin’s impact on clinical outcomes and quality of life, and there are limited data from Asia. The aim of this study is to evaluate the use of digoxin and its impact on clinical outcomes and quality of life in a high-risk cohort of elderly Chinese atrial fibrillation (AF) patients. Methods and results The Optimal Thromboprophylaxis in Elderly Chinese Patients with Atrial Fibrillation (ChiOTEAF) registry is a prospective, multicentre nationwide study conducted from October 2014 to December 2018. Endpoints of interest were the composite outcome of all-cause death/any thromboembolism (TE), all-cause death, cardiovascular death, sudden cardiac death, and TE events, as well as the quality of life. The eligible cohort for this analysis included 6391 individuals, of whom 751 (11.8%) patients were treated with digoxin. On multivariate analysis, the use of digoxin was associated with a higher odds ratio (OR) of composite outcome [OR: 1.71; 95% confidence interval (CI): 1.32–2.22], all-cause death (OR: 1.62; 95% CI: 1.23–2.14), and any TE (OR: 1.78; 95% CI: 1.08–2.95). Results were consistent in a subgroup of patients with diagnosed heart failure (HF) and patients with permanent AF. The use of digoxin was associated with worse health-related quality of life (mean EQ index: 0.76 ± 0.19 vs. 0.84 ± 0.18; P & lt; 0.001). Conclusions In this nationwide cohort study, digoxin use was associated with an overall higher risk of the composite outcome of all-cause death/any TE, all-cause death, and any TE, regardless of HF diagnosis. Patients treated with digoxin had a worse health-related quality of life.

    Abstract: Effective stroke prevention with oral anticoagulants (OAC) is recommended for some patients with atrial fibrillation (AF). We aimed to describe OAC use by geographical region and type of site in patients with recent‐onset AF enrolled in a large global registry. Methods and Results Eligible participants were recruited into GLORIA‐AF (Global Registry on Long‐Term Oral Antithrombotic Treatment in Patients With Atrial Fibrillation), a prospective observational cohort study from 2014 to 2016 in 4 international regions: North America, Europe, Asia, and Latin America. Cumulative incidence functions were generated for direct OACs (DOAC), vitamin K antagonists, and antiplatelet drugs considering competing risks, stratified by region and type of site. Time‐to‐treatment initiation after AF diagnosis was analyzed with Fine‐Gray subdistribution hazard models. A total of 21 237 patients eligible for analysis were identified. By 30 days after AF diagnosis, 40%, 16%, and 8.6% of patients had DOAC, vitamin K antagonists, and antiplatelet drugs initiated, respectively. Earlier initiation of DOACs was observed in Europe, with Asia and Latin America having lower hazard rates of DOAC time‐to‐treatment initiation than Europe (hazard ratio [HR], 0.66; 95% CI, 0.62–0.70 and HR, 0.79; 95% CI, 0.73–0.85, respectively). DOAC initiation was highest in community hospitals, vitamin K antagonists in outpatient health care centers/anticoagulation clinics, and antiplatelet drugs in primary care clinics. Conclusions Important geographic variability exists with the use of OACs for patients with AF. Differences in the time‐to‐treatment initiation of OAC by type of site suggests suboptimal implementation of guideline recommendations and could result in less benefit and more harm. Optimizing OAC use for patients with AF may improve outcomes and reduce health care costs. Registration URL: http://www.clinicaltrials.gov ; Unique identifiers: NCT01468701, NCT01671007.

    Abstract: Patients with atrial fibrillation commonly have complex clinical backgrounds of multimorbidity and polypharmacy. The Atrial Fibrillation Better Care (ABC) pathway has been developed to help deliver integrated and holistic care for patients with atrial fibrillation. In this ancillary analysis, we assessed the adherence to and the effectiveness of the ABC pathway at reducing adverse outcomes in Chinese patients with atrial fibrillation with a complex clinical background of multimorbidity or polypharmacy. Methods and Results The ChiOTEAF (Optimal Thromboprophylaxis in Elderly Chinese Patients With Atrial Fibrillation) registry is a prospective, multicenter, nationwide study conducted from October 2014 to December 2018. The primary outcomes of interest were the composite end point of all‐cause death and thromboembolic events, as well as individual end points of all‐cause death, thromboembolic events, and major bleeding. Multimorbidity was defined as the presence of ≥2 comorbidities, and polypharmacy was defined as the concomitant use of ≥5 medications. The eligible cohort included 4644 patients with multimorbidity, of whom 2610 (56.2%) had available data to assess the ABC pathway usage (mean age, 74.4±10.2; 42.8% women). Among patients with polypharmacy (n=2262; mean age, 74.6±10.1; 43.3% women), 1328 (58.7%) had available data to assess the use of the ABC pathway. Adherence to the ABC pathway was associated with a lower risk of the primary composite outcome among patients with multimorbidity (odds ratio, 0.48; 95% CI, 0.29–0.79) and in the polypharmacy group (odds ratio, 0.39; 95% CI, 0.19–0.78). Health‐related quality of life was lower in the non–ABC‐adherent group compared with the ABC‐treated patients. Conclusions This nationwide real‐world registry shows that adherence to the ABC pathway is associated with improved clinical outcomes and health‐related quality of life in clinically complex Chinese patients with atrial fibrillation with multimorbidity or polypharmacy.

    Abstract: To assess the efficacy and safety of catheter ablation (CA) compared with antiarrhythmic drugs (AADs) as first-line treatment for symptomatic paroxysmal atrial fibrillation (AF). Methods Systematic review and meta-analysis of randomised controlled trials identified using MEDLINE, Cochrane Library and Embase published between 01/01/2000 and 19/03/2021. The primary efficacy endpoint was the first documented recurrence of atrial arrhythmias following the blanking period. The primary safety endpoint was a composite of all serious adverse events (SAEs). Results From 441 records, 6 studies met the inclusion criteria. 609 patients received CA, while 603 received AAD therapy. 212/609 patients in the CA group had a recurrence of atrial arrhythmias as compared with 318/603 in the AADs group resulting in a 36% relative risk reduction (risk ratio: 0.64, 95% CI 0.51 to 0.80, p 〈 0.01). The risk of all SAEs was not statistically different between CA and AAD (0.87, 0.58 to 1.30, p=0.49); 107/609 SAE in the CA group vs 126/603 in the AAD group. Both recurrence of symptomatic atrial arrhythmias (109/505 vs 186/504) and healthcare utilisation (126/397 vs 185/394) were significantly lower in the CA group (0.53, 0.35 to 0.79 and 0.65, 0.48 to 0.89, respectively). There was a 79% reduction in the crossover rate during follow-up among patients randomised to CA compared with AAD (0.21, 0.13 to 0.32, p 〈 0.01). Conclusions First-line treatment with CA is superior to AAD therapy in patients with symptomatic paroxysmal AF, as it significantly reduces the recurrence of any atrial arrhythmias and symptomatic atrial arrhythmias, and healthcare resource utilisation with comparable safety profile.

    Abstract: Atrial fibrillation is known as the epidemic of the 21st century. This most common arrhythmia carries the risk of, inter alia, serious thromboembolic complications. Due to the paroxysmal nature of arrhythmia, the diagnosis of atrial fibrillation is not easy. New technologies and methods of minimally invasive, continuous ECG monitoring for early detection of arrhythmias are dynamically developing. The following article discusses new heart rate monitoring methods for the detection of atrial fibrillation.

    Abstract: Prospectively collected data comparing the safety and effectiveness of individual non-vitamin K antagonists (NOACs) are lacking. Our objective was to directly compare the effectiveness and safety of NOACs in patients with newly diagnosed atrial fibrillation (AF). Methods In GLORIA-AF, a large, prospective, global registry program, consecutive patients with newly diagnosed AF were followed for 3 years. The comparative analyses for (1) dabigatran vs rivaroxaban or apixaban and (2) rivaroxaban vs apixaban were performed on propensity score (PS)-matched patient sets. Proportional hazards regression was used to estimate hazard ratios (HRs) for outcomes of interest. Results The GLORIA-AF Phase III registry enrolled 21,300 patients between January 2014 and December 2016. Of these, 3839 were prescribed dabigatran, 4015 rivaroxaban and 4505 apixaban, with median ages of 71.0, 71.0, and 73.0 years, respectively. In the PS-matched set, the adjusted HRs and 95% confidence intervals (CIs) for dabigatran vs rivaroxaban were, for stroke: 1.27 (0.79–2.03), major bleeding 0.59 (0.40–0.88), myocardial infarction 0.68 (0.40–1.16), and all-cause death 0.86 (0.67–1.10). For the comparison of dabigatran vs apixaban, in the PS-matched set, the adjusted HRs were, for stroke 1.16 (0.76–1.78), myocardial infarction 0.84 (0.48–1.46), major bleeding 0.98 (0.63–1.52) and all-cause death 1.01 (0.79–1.29). For the comparison of rivaroxaban vs apixaban, in the PS-matched set, the adjusted HRs were, for stroke 0.78 (0.52–1.19), myocardial infarction 0.96 (0.63–1.45), major bleeding 1.54 (1.14–2.08), and all-cause death 0.97 (0.80–1.19). Conclusions Patients treated with dabigatran had a 41% lower risk of major bleeding compared with rivaroxaban, but similar risks of stroke, MI, and death. Relative to apixaban, patients treated with dabigatran had similar risks of stroke, major bleeding, MI, and death. Rivaroxaban relative to apixaban had increased risk for major bleeding, but similar risks for stroke, MI, and death. Registration URL: https://www.clinicaltrials.gov .

    Abstract: Adherence to guideline-directed oral anticoagulation (OAC) in patients with atrial fibrillation (AF) improves outcomes, but limited data are available from China. We evaluated the adherence to guideline-directed anticoagulation and its impact on clinical outcomes in a high-risk cohort of elderly Chinese patients. Methods and results The Optimal Thromboprophylaxis in Elderly Chinese Patients with Atrial Fibrillation (ChiOTEAF) registry is a prospective, multicentre study conducted from October 2014 to December 2018. Endpoints of interest were all-cause death, thromboembolic (TE) events and major bleedings in patients with a guideline-directed indication for OACs (CHA2DS2-VASc ≥1 if male or ≥2 if female). The eligible cohort consisted of 5742 patients, of whom 2567 (44.7%) patients were treated with an OAC. Seven independent predictors of OAC undertreatment were identified: age [odds ratio (OR): 1.04; 95% confidence interval (CI): 1.03–1.05; P  & lt; 0.001], first diagnosed AF (OR: 1.71; 95%CI: 1.44–2.03; P  & lt; 0.001), chronic kidney disease (OR: 1.67; 95%CI: 1.36–2.06; P  & lt; 0.001), liver disease (OR: 1.69; 95%CI: 1.19–2.41; P = 0.003), dementia (OR: 1.67; 95%CI: 1.06–2.64; P = 0.026), prior extracranial bleeding (OR: 1.89; 95%CI: 1.35–2.64; P  & lt; 0.001), and the use of antiplatelet drug (OR: 6.97; 95%CI: 5.89–8.23; P  & lt; 0.001). On multivariate analysis, OAC undertreatment was significantly associated with a higher risk all-cause death (OR: 3.79; 95%CI: 2.61–5.53; P  & lt; 0.001) and TE events (OR: 2.28; 95%CI: 1.39–3.72; P = 0.001), and a similar risk of major bleeding as compared with guideline-directed OAC therapy. Conclusion Only 44.7% of all eligible patients were prescribed OAC in accordance with guideline recommendations. The independent predictors for OAC undertreatment were age, first diagnosed AF, chronic kidney disease, chronic obstructive pulmonary disease, prior extracranial bleeding, and the use of the antiplatelet drugs. Guideline-adherent thromboprophylaxis was safe and may be associated with improved survival and less TE among elderly Chinese patients with AF.

    Abstract: To evaluate the quality measures and clinical performance indicators among elderly Chinese patients with atrial fibrillation (AF). The management of patients with AF requires a holistic, multidisciplinary approach. Quality indicators have been proposed to assess the quality of care in ‘real-world’ clinical practice when managing patients with AF. Methods and results The Optimal Thromboprophylaxis in Elderly Chinese Patients with Atrial Fibrillation (ChiOTEAF) registry is a prospective, observational, large-scale multicentre registry conducted between October 2014 and December 2018 in China. Data were collected at the enrolment and during the follow-up visits by the local investigators. In the ChiOTEAF registry, 14 primary and 8 secondary indicators from six domains of care were assessed. Six thousand four hundred twenty patients who completed the 1-year follow-up were included in the analysis. Median age was 76 years, and the majority of patients was male (60.8%). Overall, 3246 patients (54.8%) were not treated with oral anticoagulants (OACs) appropriate to their risk of stroke; specifically, among those at highest risk of stroke, OACs were prescribed in only 43.3% patients (1258/2905). Among patients with permanent AF, 32 (3.6%) were prescribed antiarrhythmic drugs, and among those with paroxysmal AF, catheter ablation was performed in 20.7%. Patients were overburdened with multi-morbidities, including hypertension, diabetes mellitus, obesity, and sleep apnoea. During 1-year follow-up, 435 deaths (6.8%) and 89 thromboembolic events (1.4%) occurred. Patient-reported outcomes showed that 55% of patients had indicators of reduced quality of life. Conclusion Assessment of quality indicators revealed the gaps in AF care among Chinese patients, highlighting the need for a more integrated or holistic approach to AF management.

    Abstract: To assess and compare long-term mortality and predictors thereof in de novo cardiac resynchronization therapy defibrillators (CRT-D) vs. upgrade from an implantable cardioverter-defibrillator (ICD) to CRT-D. Methods and results  Study population consisted of 595 consecutive patients with CRT-D implanted between 2002 and 2015 in a tertiary care, university hospital, in a densely inhabited, urban region of Poland [480 subjects (84.3%) with CRT-D de novo implantation; 115 patients (15.7%) upgraded from ICD to CRT-D]. In a median observation of 1692 days (range 457–3067), all-cause mortality for d e novo CRT-D vs. CRT-D upgrade was 35.5% vs. 43.5%, respectively (P = 0.045). On multivariable regression analysis including all CRT recipients, the previously implanted ICD was an independent predictor for death [hazard ratio (HR) 1.58, 95% confidence interval (CI) 1.10–2.29, P = 0.02]. For those, who were upgraded from ICD to CRT-D, the independent predictors for all-cause death were as follows: creatinine level (HR 1.01, 95% CI 1.00–1.02, P = 0.01), left ventricular end-systolic diameter (HR 1.07, 95% CI 1.02–1.11, P = 0.002), New York Heart Association (NYHA) IV class at baseline (HR 2.36, 95% CI 1.00–5.53, P = 0.049) and cardiac device-related infective endocarditis during follow-up (HR 2.42, 95% CI 1.02–5.75, P = 0.046). A new CRT scale (Creatinine ≥150 μmol/L; Remodelling, left ventricular end-systolic ≥59 mm; Threshold for NYHA, NYHA = IV) showed high prediction for mortality in CRT-D upgrades (AUC 0.70, 95% CI 0.59–0.80, P = 0.0007). Conclusion  All-cause mortality in patients upgraded from ICD is significantly higher compared with de novo CRT-D implantations and reaches almost 45% within 4.5 years. A new CRT scale (Creatinine; Remodelling; Threshold for NYHA) has been proposed to help survival prediction following CRT upgrade.
