Late incidence and recurrence of new-onset atrial fibrillation after isolated surgical aortic valve replacement

Publisher Copyright: © 2021 The AuthorsObjectives: Atrial fibrillation (AF) is a common complication after cardiac surgery. More knowledge is needed about long-term AF recurrence and adverse outcomes related to new-onset AF (NOAF) during the index hospitalization. Methods: A total of 1073 patients underwent isolated surgical aortic valve replacement at the 4 participating hospitals (2002-2014). After the exclusion of patients with a history of any preoperative AF, the final study population included 529 patients in the bioprosthetic and 253 patients in the mechanical valve prosthesis cohort. Median follow-up time was 5.4 (interquartile range, 3.4-8.2) years in the combined cohort. Results: Altogether 333 (42.6%) patients had in-hospital NOAF and 250 (32.0%) AF after hospital discharge. In the mechanical cohort, 64 (25.3%) experienced in-hospital NOAF and 74 (29.2%) AF after hospital discharge, whereas in the bioprosthetic cohort, 269 (50.9%) patients had in-hospital NOAF and 176 (33.3%) AF after hospital discharge. Patients with NOAF during the index hospital stay had a multifold risk of AF after hospital discharge in the combined cohort (hazard ratio [HR], 3.68; 95% confidence interval [CI], 2.82-4.81; P <.0001) as well as in both cohorts separately (bioprosthetic: HR, 4.35; 95% CI, 3.05-6.22; P <.001; mechanical: HR, 2.54; 95% CI, 1.59-4.03; P <.001). Patients with an in-hospital NOAF also had a significantly higher adjusted risk of death during the follow-up in the mechanical (HR, 2.05; 95% CI, 1.10-3.82; P =.025) and bioprosthetic (HR, 1.63; 95% CI, 1.17-2.28; P =.004) valve prosthesis cohorts. Conclusions: NOAF during the index hospitalization is associated with a 2- to 4-fold risk of later AF and 1.6- to 2.0-fold risk of all-cause mortality after mechanical and bioprosthetic surgical aortic valve replacement.Peer reviewe

We aimed to assess whether the initiation of oral anticoagulant (OAC) therapy in patients with AF differs between those with rural and urban residence. Methods The registry-based FinACAF cohort covers all patients with AF from all levels of care in Finland. Patients were divided into rural and urban categories and into urbanization degree tertiles based on their municipality of residence at the time of AF diagnosis. The outcome was the first redeemed OAC prescription. Results We identified 222 419 patients (50.1% female; mean age 72.8 (SD 13.2) years) with incident AF during 2007–2018. Urban residence was associated with a lower rate of OAC therapy initiation (adjusted subdistribution hazard ratio (SHR) (95% CI) 0.96 (0.95–0.97)). Correspondingly, an inverse graded dose-response relationship was observed between higher urbanization degree tertile and OAC initiation rate (highest tertile compared to lowest: adjusted SHR (95% CI) 0.94 (0.93–0.95)). The adoption of direct oral anticoagulants for stroke prevention was faster among patients with urban residence. Conclusion This nationwide cohort study documented that urban residence is associated with a slightly lower rate of OAC therapy initiation in patients with incident AF, but faster adoption of direct oral anticoagulant use.Peer reviewe

Publisher Copyright: © Author(s) 2023.Aims: Rural–urban disparities have been reported in the outcomes of cardiovascular diseases. We assessed whether rural–urban or other geographical disparities exist in the risk of ischemic stroke (IS) and death in patients with atrial fibrillation (AF) in Finland. Methods: The registry-based FinACAF cohort study covers all patients with AF from all levels of care in Finland from 2007 to 2018. Patients were divided into rural–urban categories and into hospital districts (HDs) based on their municipality of residence. Results: We identified 222,051 patients (50.1% female; mean age 72.8 years; mean follow-up 3.9 years) with new-onset AF, of whom 15,567 (7.0%) patients suffered IS and 72,565 (32.7%) died during follow-up. The crude IS rate was similar between rural and urban areas, whereas the mortality rate was lower in urban areas (incidence rate ratios (IRRs) with 95% confidence intervals (CIs) 0.97 (0.93–1.00) and 0.92 (0.91–0.93), respectively). However, after adjustments, urban residence was associated withslightly higher IS and mortality rates (IRRs with 95% CIs 1.05 (1.01–1.08) and 1.06 (1.04–1.07), respectively). The highest crude IS rate was in the East Savo HD and the lowest in Åland, whereas the highest crude mortality rate was in the Länsi-Pohja HD and the lowest in the North Ostrobothnia HD (IRRs with 95% CIs compared to Helsinki and Uusimaa HD for IS 1.46 (1.28–1.67) and 0.79 (0.62–1.01), and mortality 1.24 (1.16–1.32) and 0.97 (0.93–1.00), respectively. Conclusions: Rural–urban differences in prognosis of AF in Finland appear minimal, whereas considerable disparities exist between HDs.Peer reviewe

We assessed the hypothesis that AF patients with higher income or educational level are more frequently initiated with oral anticoagulant (OAC) therapy for stroke prevention. Methods: The nationwide registry-based Finnish AntiCoagulation in Atrial Fibrillation cohort covers all patients with AF from all levels of care in Finland. Patients were divided into income quartiles according to their highest annual income during 2004-2018 and into three categories based on educational attainment. The outcome was the first redeemed OAC prescription. Results: We identified 239 222 patients (mean age 72.7 ± 13.2 years, 49.8% female) with incident AF during 2007-2018. Higher income was associated with higher OAC initiation rate: compared to the lowest income quartile the adjusted SHRs (95% CI) for OAC initiation were 1.09 (1.07-1.10), 1.13 (1.11-1.14) and 1.13 (1.12-1.15) in the second, third and fourth income quartiles, respectively. Patients in the highest educational category had a slightly lower OAC initiation rate than patients in the lowest educational category (adjusted SHR 0.92 [95% CI 0.90-0.93]). Income-related disparities were larger and education-related disparities only marginal among patients at high risk of ischemic stroke. The socioeconomic disparities in OAC initiation within 1-year follow-up decreased from 2007 to 2018. The adoption of direct OACs as the initial anticoagulant was faster among patients with higher income or educational levels. Conclusion: These findings highlight potential missed opportunities in stroke prevention, especially among AF patients with low income, whereas the education-related disparities in OAC initiation appear controversial.Peer reviewe

Oral Anticoagulant Therapy and Risk of Admission to Long-Term Care in patients With Atrial Fibrillation

Funding Information: Funding/Support: This work was supported by the Aarne Koskelo Foundation , The Finnish Foundation for Cardiovascular Research , and Helsinki and Uusimaa Hospital District Research Fund ( TYH2019309 ). Publisher Copyright: © 2023 The AuthorsObjectives: The impact of oral anticoagulants (OACs) on the need of long-term care (LTC) in the aging and multimorbid population of patients with atrial fibrillation (AF) is unknown. We conducted a nationwide cohort study to evaluate the effect of OACs on the need of LTC. Design: Retrospective nationwide cohort study. Setting and Participants: The registry-based FinACAF cohort study covers all patients with incident AF from all levels of care in Finland from 2007 to 2018, as well as all their OAC purchases, LTC admissions, and information on previous home care acuity. Methods: Incidence rate ratios (IRRs) of LTC admission were calculated using Poisson regression models with a Lexis-type data structure based on 3 time scales: follow-up time from AF diagnosis, calendar year, and age. Results: We identified 188,752 patients (49.0% female; mean age 71.4 years; mean follow-up 3.6 years) with incident AF without prior LTC, of whom 143,534 (76.0 %) initiated OAC therapy and 11,775 (6.2 %) were admitted to LTC. OAC therapy was associated with lower rates of LTC admission (adjusted IRR 0.79, 95% CI 0.76-0.82). When compared to warfarin, direct oral anticoagulants (DOACs) were associated with lower LTC admission rate (adjusted IRR 0.69, 95% CI 0.61-0.79). No significant disparities were observed between different DOACs. Conclusions and Implications: OAC therapy, particularly with DOACs, is associated with a substantially lower risk of admission to LTC in patients with AF. Increasing guideline-based OAC coverage among patients with AF may prevent the need of LTC, lengthen survival at home, and potentially decrease health care costs.Peer reviewe

Publisher Copyright: © 2022 by the authors.Background: Rural–urban disparities have been reported in the access, utilization, and quality of healthcare. We aimed to assess whether use of antiarrhythmic therapies (AATs) in patients with atrial fibrillation (AF) differs between those with rural and urban residence. Methods: The registry-based FinACAF cohort covers all patients with AF from all levels of care in Finland. Patients were divided into rural and urban categories and into urbanization degree tertiles based on their municipality of residence at the time of AF diagnosis. The primary outcome was the use of any AAT, including cardioversion, catheter ablation, and fulfilled antiarrhythmic drug (AAD) prescription. Results: We identified 177,529 patients (49.9% female, mean age 73.0 (SD13.0) years) with incident AF during 2010–2018. Except for AADs, the differences in AAT use were nonsignificant when patients were stratified according to the rural–urban classification system (urban vs. rural adjusted incidence rate ratios (aIRRs) with 95% CIs for anyAAT 1.01 (0.99–1.03), AADs 1.11 (1.07–1.15), cardioversion 1.01 (0.98–1.03), catheter ablation 1.05 (0.98–1.12)). However, slightly higher use of all rhythm control modalities was observed in the highest urbanization degree tertile when compared to the lowest tertile (aIRRs with 95% Cis for any AAT 1.06 (1.03–1.08), AADs 1.18 (1.14–1.23), cardioversion 1.05 (1.02–1.08), catheter ablation 1.10 (1.02–1.19)). Conclusions: This nationwide retrospective cohort study observed that urban residence is associated with higher use of AADs in patients with incident AF. Otherwise, the observed disparities were only marginal, suggesting that in the use of rhythm control therapies, no large rural–urban inequity exists in Finland.Peer reviewe

A randomized prospective multicenter trial for stroke prevention by prophylactic surgical closure of the left atrial appendage in patients undergoing bioprosthetic aortic valve surgery--LAA-CLOSURE trial protocol

Patients undergoing surgical aortic valve replacement (SAVR) are at high risk for atrial fibrillation (AF) and stroke after surgery. There is an unmet clinical need to improve stroke prevention in this patient population. The LAA-CLOSURE trial aims to assess the efficacy and safety of prophylactic surgical closure of the left atrial appendage for stroke and cardiovascular death prevention in patients undergoing bioprosthetic SAVR. This randomized, open-label, prospective multicenter trial will enroll 1,040 patients at 13 European sites. The primary endpoint is a composite of cardiovascular mortality, stroke and systemic embolism at 5 years. Secondary endpoints include cardiovascular mortality, stroke, systemic embolism, bleed fulfilling academic research consortium (BARC) criteria, hospitalization for decompensated heart failure and health economic evaluation. Sample size is based on 30% risk reduction in time to event analysis of primary endpoint. Prespecified reports include 30-day safety analysis focusing on AF occurrence and short-term outcomes and interim analyses a
