RESUMO
BACKGROUND AND AIMS: Female sex has been linked with higher risk of ischaemic stroke (IS) in atrial fibrillation (AF), but no prior study has examined temporal trends in the IS risk associated with female sex. METHODS: The registry-linkage Finnish AntiCoagulation in Atrial Fibrillation (FinACAF) study included all patients with AF in Finland from 2007 to 2018. Ischaemic stroke rates and rate ratios were computed. RESULTS: Overall, 229 565 patients with new-onset AF were identified (50.0% women; mean age 72.7 years). The crude IS incidence was higher in women than in men across the entire study period (21.1 vs. 14.9 events per 1000 patient-years, P < .001), and the incidence decreased both in men and women. In 2007-08, female sex was independently associated with a 20%-30% higher IS rate in the adjusted analyses, but this association attenuated and became statistically non-significant by the end of the observation period. Similar trends were observed when time with and without oral anticoagulant (OAC) treatment was analysed, as well as when only time without OAC use was considered. The decrease in IS rate was driven by patients with high IS risk, whereas in patients with low or moderate IS risk, female sex was not associated with a higher IS rate. CONCLUSIONS: The association between female sex and IS rate has decreased and become non-significant over the course of the study period from 2007 to 2018, suggesting that female sex could be omitted as a factor when estimating expected IS rates and the need for OAC therapy in patients with AF.

BACKGROUND: Limited data exist on the temporal relationship between new-onset atrial fibrillation (AF) and ischemic stroke and its impact on patients' clinical characteristics and mortality. METHODS: A population-based registry-linkage database includes all patients with new-onset AF in Finland from 2007 to 2018. Ischemic stroke temporally associated with AF (ISTAF) was defined as an ischemic stroke occurring within ±30 days from the first AF diagnosis. Clinical factors associated with ISTAF were studied with logistic regression and 90-day survival with Cox proportional hazards analysis. RESULTS: Among 229â 565 patients with new-onset AF (mean age, 72.7 years; 50% female), 204â 774 (89.2%) experienced no ischemic stroke, 12â 209 (5.3%) had past ischemic stroke >30 days before AF, and 12â 582 (5.8%) had ISTAF. The annual proportion of ISTAF among patients with AF decreased from 6.0% to 4.8% from 2007 to 2018. Factors associated positively with ISTAF were higher age, lower education level, and alcohol use disorder, whereas vascular disease, heart failure, chronic kidney disease cancer, and psychiatric disorders were less probable with ISTAF. Compared with patients without ischemic stroke and those with past ischemic stroke, ISTAF was associated with ≈3-fold and 1.5-fold risks of death (adjusted hazard ratios, 2.90 [95% CI, 2.76-3.04] and 1.47 [95% CI, 1.39-1.57], respectively). The 90-day survival probability of patients with ISTAF increased from 0.79 (95% CI, 0.76-0.81) in 2007 to 0.89 (95% CI, 0.87-0.91) in 2018. CONCLUSIONS: ISTAF depicts the prominent temporal clustering of ischemic strokes surrounding AF diagnosis. Despite having fewer comorbidities, patients with ISTAF had worse, albeit improving, survival than patients with a history of or no ischemic stroke.

AIMS: To investigate sex-specific temporal trends in the initiation of oral anticoagulant (OAC) therapy among patients diagnosed with atrial fibrillation (AF) in Finland between 2007 and 2018. METHODS: The registry-linkage Finnish AntiCoagulation in Atrial Fibrillation (FinACAF) Study included all patients with incident AF in Finland from 2007 to 2018. The primary outcome was the initiation of any OAC therapy. RESULTS: We identified 229,565 patients with new-onset AF (50.0% women; mean age 72.7 years). The initiation of OAC therapy increased continuously during the observation period. While women were more likely to receive OAC therapy overall, after adjusting for age, stroke risk factors and other confounding factors, female sex was associated with a marginally lower initiation of OACs (unadjusted and adjusted hazard ratios comparing women to men: 1.08 (1.07-1.10) and 0.97 (0.96-0.98), respectively). Importantly, the gender disparities in OAC use attenuated and reached parity by the end of the observation period. Furthermore, when only patients eligible for OAC therapy according to the contemporary guidelines were included in the analyses, the gender inequalities in OAC initiation appeared minimal. Implementation of direct OACs for stroke prevention was slightly slower among women. CONCLUSION: This nationwide retrospective cohort study covering all patients with incident AF in Finland from 2007 to 2018 observed that although female sex was initially associated with a lower initiation of OAC therapy, the sex-related disparities resolved over the course of the study period.

AIMS: Elective cardioversion (ECV) is routinely used in atrial fibrillation (AF) to restore sinus rhythm. However, it includes a risk of thromboembolism even during adequate oral anticoagulation treatment. The aim of this study was to evaluate the risk of thromboembolic and bleeding complications after ECV in a real-life setting utilizing data from a large AF population. METHODS AND RESULTS: This nationwide register-based study included all (n = 9625) Finnish AF patients undergoing their first-ever ECV between 2012 and 2018. The thromboembolic and bleeding complications within 30 days after ECV were analysed. The mean age of the patients was 67.7 ± 9.9 years, 61.2% were men, and the mean CHA2DS2-VASc score was 2.6 ± 1.6. Warfarin was used in 6245 (64.9%) and non-vitamin K oral anticoagulants (NOACs) in 3380 (35.1%) cardioversions. Fifty-two (0.5%) thromboembolic complications occurred, of which 62% were ischaemic strokes, 25% transient ischaemic attacks, and 13% other systemic embolisms. Thromboembolic events occurred in 14 (0.4%) NOAC-treated patients and in 38 (0.6%) warfarin-treated patients (odds ratio 0.77; confidence interval: 0.42-1.39). The median time from ECV to the thromboembolic event was 2 days, and 78% of the events occurred within 10 days. Age and alcohol abuse were significant predictors of thromboembolic events. Among warfarin users, thromboembolic complications were more common with international normalized ratio (INR) <2.5 than INR ≥2.5 (0.9% vs. 0.4%, P = 0.026). Overall, 27 (0.3%) bleeding events occurred. CONCLUSION: The rate of thromboembolic and bleeding complications related to ECV was low without significant difference between NOAC- and warfarin-treated patients. With warfarin, INR ≥2.5 at the time of cardioversion reduced the risk of thromboembolic complications.

BACKGROUND: We conducted a comparative analysis of hypertension prevalence, progression, and treatment in two Finnish population-based cohorts comprising older adults born 20 years apart. The study covered data from pre- and post-HYVET Study eras and spanned the onset of the COVID-19 pandemic. METHODS: All 70-year-old home-dwelling citizens of Turku, in Southwest Finland, were invited to participate in the survey in 1990 (1920-born TUVA cohort) and in 2010 (1940-born UTUVA cohort) with a 25-year follow-up plan. The analyses included those with available data for systolic and diastolic blood pressure (BP), yielding 1015 TUVA and 888 UTUVA participants at baseline. Biomarkers associated with BP were analysed with t- and chi-square tests. RESULTS: At baseline, 83.4% of TUVA and 74.3% of UTUVA participants had uncontrolled BP, with respective antihypertensive medication usage at 36.0% and 55.9% (p < .001 for both between-cohort differences). Systolic BP exhibited an inverted U-shaped trajectory, with TUVA initially 7.8 mmHg higher at 155.4 mmHg than UTUVA (p < .001). However, by the ages 80-82, the difference in systolic BP trajectories between the cohorts was attenuated to 4.0 mmHg (p = .03). Diastolic BP differences were less clinically significant. UTUVA demonstrated higher use of all five conventional antihypertensive categories than TUVA (p ≤ .02 for all categories). CONCLUSIONS: In the early years of older adulthood, the 1940-born cohort showed a positive trend in hypertension management, yet maintained a 74.3% baseline rate of uncontrolled BP. Furthermore, by the ages 81-82, the benefits observed over the 1920-born cohort had lessened, influenced by the COVID-19 pandemic or other lasting factors. Heightened efforts to improve hypertension treatment in older adults remain crucial in the post-HYVET era.
We studied two generational cohorts of older adults from Finland, born 20 years apart, to examine changes in blood pressure readings over time, the prevalence of high blood pressure, and its treatment. Our investigation spanned periods both before and after the HYVET Study, a significant research effort demonstrating the benefits of treating hypertension in older adult patients, reducing the risk of stroke and other causes of mortality. Additionally, we considered the potential impact of the COVID-19 pandemic on blood pressure control.We invited all 70-year-olds living at home in Turku, Southwest Finland, to participate in our survey in 1990 (the 1920-born cohort) and in 2010 (the 1940-born cohort), with plans to follow them for 25 years. We collected data on their blood pressure readings and the medications they were prescribed.At the outset of our study, when participants were 70 years old, a higher proportion of individuals in the 1920-born cohort had uncontrolled high blood pressure compared to those in the 1940-born group. In addition, the participants born in 1940 showed increased usage and a wider selection of antihypertensive medications compared to the 1920-born cohort. Despite this, over 70% of the 70-year-olds even in the 1940-born cohort still had uncontrolled blood pressure. Furthermore, by the time these individuals reached their early 80s, the initial improvements in blood pressure control over the 1920-born cohort had somewhat diminished.Our findings underscore the ongoing need for improvements in managing high blood pressure among older adults. This remains crucial as individuals age, emphasising the importance of continued research to develop better treatment approaches, even after landmark studies like HYVET.

OBJECTIVES: We assessed if positive life orientation (PLO) has increased among older individuals and explored gender disparities in PLO changes. METHODS: Two cohorts of 70-year-olds from Turku, Finland were included: the 1920 birth cohort (examined in 1991; n = 1,032) and the 1940 birth cohort (examined in 2011; n = 956). Participants completed an identical questionnaire assessing life satisfaction, feeling needed, future plans, zest for life, depression, and loneliness. A composite PLO score (range 0-1) was computed. RESULTS: The 2011 cohort had a higher mean PLO score than the 1991 cohort (.87 vs. .83, p < .001). The 2011 cohort reported higher sense of being needed, more future plans, and reduced loneliness (all p < .001). No significant differences were found in life satisfaction, zest for life, or depression. Gender disparities in PLO persisted across both cohorts, with men scoring slightly higher but following similar trends as women. DISCUSSION: PLO appears to have increased among older individuals. CLINICAL IMPLICATIONS: Recognizing the rising trend of PLO in recent decades may influence the development of societal and healthcare policies to further improve overall well-being among older individuals.
RESUMO
AIMS: Socioeconomic disparities have been reported in the outcomes of patients with atrial fibrillation (AF). 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.

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 with slightly 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.
RESUMO
BACKGROUND: Atrial fibrillation (AF) patients with mental health conditions (MHCs) have higher incidence of ischaemic stroke (IS) than patients without MHC, but whether this results from direct impact of MHCs or relates to higher prevalence of comorbidities and differences in the use of oral anticoagulant (OAC) therapy is unclear. We assessed the hypothesis that MHCs independently increase the risk of IS in patients with incident AF. METHODS: The nationwide FinACAF cohort covered all 203,154 patients diagnosed with incident AF without previous IS or transient ischaemic attack in Finland during 2007-2018. MHCs of interest were depression, bipolar disorder, anxiety disorder, schizophrenia and any MHC. The outcomes were first-ever IS and all-cause death. RESULTS: The patients' (mean age 73.0 ± 13.5 years, 49.0% female) mean follow-up time was 4.3 (SD 3.3) years and 16,272 (8.0%) experienced first-ever IS and 63,420 (31.2%) died during follow-up. After propensity score matching and adjusting for OAC use, no MHC group was associated with increased IS risk (adjusted SHRs (95% CI): depression 0.961 (0.857-1.077), bipolar disorder 1.398 (0.947-2.006), anxiety disorder 0.878 (0.718-1.034), schizophrenia 0.803 (0.594-1.085) and any MHC 1.033 (0.985-1.085)). Lower rate of OAC use partly explained the observed higher crude IS incidence in patients with any MHC. Depression, schizophrenia and any MHC were associated with higher all-cause mortality (adjusted HRs [95% CI]: 1.208 [1.136-1.283], 1.543 [1.352-1.761] and 1.149 [1.116-1.175], respectively). CONCLUSIONS: In this nationwide retrospective cohort study, MHCs were not associated with the incidence of first-ever IS in patients with AF.

Background: Contemporary data have shown a decrease in the ischaemic stroke risk associated with female sex in patients with atrial fibrillation (AF). We evaluated temporal trends in the predictive value of a non-sex CHA2DS2-VASc risk score (ie. CHA2DS2-VA). Methods: The FinACAF study covers all patients with incident AF between 2007 and 2018 in Finland from all levels of care. The CHA2DS2-VA score was compared with the CHA2DS2-VASc using continuous and category-based net reclassification indices (NRIs), integrated discrimination improvement (IDI), c-statistics and decision curve analyses. Findings: We identified 144,879 anticoagulant naïve patients with new-onset AF between 2007 and 2018 (49.9% women; mean age 72.1 years), of whom 3936 (2.7%) experienced ischaemic stroke during one-year follow-up. Based on both continuous and category-based NRIs, the CHA2DS2-VA score was inferior to the CHA2DS2-VASc in the early years (-0.333 (95% CI -0.411 to -0.261) and -0.118 (95% CI -0.137 to -0.099), respectively). However, the differences attenuated over time, and by the end of the study period, the continuous NRI became non-significant (-0.093 (95% CI -0.165 to 0.032)), whereas the category-based NRI reversed in favor of the CHA2DS2-VA (0.070 (95% CI 0.048-0.087)). The IDI was non-significant in early years (0.0009 (95% CI -0.0024 to 0.0037)), but over time became statistically significant in favor of the CHA2DS2-VA score (0.0022 (95% CI 0.0001-0.0044)). The Cox models fitted with the CHA2DS2-VA and the CHA2DS2-VASc scores exhibited comparable discriminative capability in the beginning of the study (p-value 0.63), but over time marginal differences in favor of the CHA2DS2-VA score emerged (p-value 0.0002). Interpretation: In 2007-2008 (when females had higher AF-related stroke risks than males), the CHA2DS2-VASc score outperformed the CHA2DS2-VA score, but the initial differences between the scores attenuated over time. By the end of the study period in 2017-2018 (with limited/no sex differences in AF-related stroke), there was marginal superiority for the CHA2DS2-VA score. Funding: This work was supported by the Aarne Koskelo Foundation, The Finnish Foundation for Cardiovascular Research, The Finnish State Research funding, and Helsinki and Uusimaa Hospital District research fund.
RESUMO
Myocardial infarction (MI) and atrial fibrillation (AF) are commonly seen in the same patient. In this study, we evaluated the temporal relations and prognosis of MI and AF. This is a substudy of the nationwide registry-based Finnish Anticoagulation in Atrial Fibrillation (FinACAF) study, comprising all Finnish patients with new-onset AF from 2010 to 2017. Patients with MI and AF were divided into groups depending on the temporal relation between the disease onsets: (1) MI before AF (MIAssuntos

RESUMO
BACKGROUND: Little is known how individual time-in-therapeutic-range (TTR) impacts the effectiveness and safety of warfarin therapy compared to direct oral anticoagulants (DOACs) in patients with atrial fibrillation (AF). OBJECTIVE: To compare the effectiveness and safety of standard dose DOACs to warfarin in patients with AF, while categorizing warfarin treated patients into quartiles based on their individual TTR. MATERIALS AND METHODS: We conducted a nationwide study including all patients with new-onset AF between 2011 and 2018 in Finland. Hazard ratios (HR) were calculated using Cox regression analysis with the inverse probability of treatment weighted method to assess the risks of ischaemic stroke (IS), intracranial haemorrhage (ICH) and mortality for users of apixaban (n = 12,426), dabigatran (n = 4545), rivaroxaban (n = 12,950) and warfarin (n = 43,548). RESULTS: The median TTR for warfarin users was 72%. Compared to the second best TTR quartile (reference), the risk of IS was higher in the two poorest TTR quartiles, and lower in the best TTR quartile and on rivaroxaban [2.35 (95% confidence interval, 1.85-2.85), 1.44 (1.18-1.75), 0.60 (0.47-0.77) and 0.72 (0.56-0.92)]. These differences were non-significant for apixaban and dabigatran. HR of ICH was 6.38 (4.88-8.35) and 1.87 (1.41-2.49) in the two poorest TTR groups, 1.44 (1.02-1.93) on rivaroxaban, and 0.58 (0.40-0.85) in the best TTR group compared to the reference group. Mortality was higher in the two poorest TTR groups and lowest in the best TTR group. CONCLUSIONS: The outcome was unsatisfactory in the two lowest TTR quartiles - in half of the patients treated with warfarin. The differences between the high TTR groups and standard dose DOACs were absent or modest.

INTRODUCTION: Chronic kidney disease (CKD) is associated with an increased incidence of atrial fibrillation (AF). Also, patients with AF are prone to adverse kidney outcomes. We examined comorbidities and medication use in patients with CKD and incident AF. METHODS: The Finnish AntiCoagulation in Atrial Fibrillation (FinACAF) is a nationwide retrospective register-linkage study including data from 168,233 patients with incident AF from 2007 to 2018, with laboratory data from 2010 onwards. Estimated glomerular filtration rate (eGFR) was available for 124,936 patients. The cohort was divided into 5 CKD stages with separate groups for dialysis and kidney transplantation. RESULTS: At AF diagnosis eGFR <60 mL/min/1.73 m2 was found in 27%, while 318 (0.3%) patients were on dialysis, and 188 (0.2%) had a functioning kidney transplant. Lowering eGFR yielded more comorbidities and medications. During 2010-2018 in patients with eGFR <60 mL/min/1.73 m2 prevalence of hypertension, dyslipidaemia, and diabetes increased from 82 to 88%, from 50 to 66% and from 25 to 33%, respectively (<0.001). Throughout the observation period, lipid-lowering medication was underused. CONCLUSION: More than one-fourth of patients with incident AF also had CKD stage 3-5 (eGFR <60 mL/min/1.73 m2). Both comorbidities and medication use increased with worsening kidney function. Prevalence of major cardiovascular (CV) risk factors increased during 2010-2018, but the use of survival-affecting medications, such as lipid-lowering medication, was suboptimal at all stages of CKD. More attention should be given to the optimal treatment of risk factors in this high CV risk population.
RESUMO
OBJECTIVES: 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.

Background Patients with aortic stenosis (AS) have been underrepresented in the trials evaluating direct oral anticoagulants (DOACs) in atrial fibrillation (AF). We aimed to assess whether AS impacts outcomes in patients with AF and estimate the effects of DOACs versus warfarin in patients with AF and AS. Methods and Results The registry-based FinACAF (Finnish Anticoagulation in Atrial Fibrillation) study covered all patients with AF diagnosed during 2007 to 2018 in Finland. Hazard ratios (HRs) of first-ever gastrointestinal bleeding, intracranial bleeding, any bleeding, ischemic stroke, and death were estimated with cause-specific hazards regression adjusted for anticoagulant exposure variables. We identified 183 946 patients (50.5% women; mean age, 71.7 [SD, 13.5] years) with incident AF without prior bleeding or ischemic stroke, of whom 5231 (2.8%) had AS. The crude incidence rate of all outcomes was higher in patients with AS than in patients without AS. After propensity score matching, AS was associated with the hazard of any bleeding, gastrointestinal bleeding, and death but not with intracranial bleeding or ischemic stroke (adjusted HRs, 1.36 [95% CI, 1.25-1.48], 1.63 [95% CI, 1.43-1.86], 1.32 [95% CI, 1.26-1.38], 0.96 [95% CI, 0.78-1.17], and 1.11 [95% CI, 0.99-1.25], respectively). Among patients with AS, DOACs were associated with a lower risk of ischemic stroke when compared with warfarin, while bleeding and mortality did not differ between DOACs and warfarin. Conclusions AS is associated with substantially higher risk of gastrointestinal bleeding in patients with AF. DOACs may be more effective in preventing ischemic stroke than warfarin in patients with AF and AS. Registration URL: https://www.clinicaltrials.gov; Unique identifier: NCT04645537.

AIMS: We assessed the temporal trends in the prevalence of diabetes and in its associations with outcomes among patients with atrial fibrillation (AF). METHODS: The registry-based FinACAF study covered all patients with incident AF in Finland between 2007 and 2018. Ischemic stroke (IS) and mortality rates were computed using Poisson regression model. RESULTS: We identified 229565 patients (50.0% female; mean age 72.7 years; mean follow-up 4.0 years) patients with incident AF. The prevalence of diabetes increased steadily from 15.5% in 2007 to 26.3% in 2018. A decrease in IS and mortality rates was observed during the study period both in patients with and without diabetes. Diabetes was associated with IS and mortality (adjusted incidence rate ratios with 95% confidence intervals 1.22 (1.17-1.26) and 1.32 (1.29-1.34), respectively). The impact of diabetes on IS risk remained stable, while its effect on mortality increased slightly during the observation period. CONCLUSIONS: The prevalence of diabetes has increased considerably among patients with AF between 2007 and 2018. There have been substantial improvements in the prognosis of AF patients with diabetes. However, diabetes remains a significant risk factor for IS and mortality in this patient population.

AIMS: Guidelines on the management of atrial fibrillation (AF) have evolved significantly during the past two decades, but the concurrent developments in real-life management and prognosis of AF are unknown. We assessed trends in the treatment and outcomes of patients with incident AF between 2007 and 2017. METHODS AND RESULTS: The registry-based nationwide FinACAF (Finnish AntiCoagulation in Atrial Fibrillation) cohort covers all patients with AF in Finland from all levels of care. We determined the proportion of patients who were treated with oral anticoagulants (OACs) or rhythm control therapies, experienced an ischaemic stroke or bleeding event requiring hospitalization, or died within 1-year follow-up after AF diagnosis. We identified 206 909 patients (mean age 72.6 years) with incident AF. During the study period, use of OACs increased from 43.6 to 76.3%, and the increase was most evident in patients with at least moderate stroke risk. One-year mortality decreased from 13.3 to 10.6%, and the ischaemic stroke rate from 5.3 to 2.2%. The prognosis especially improved in patients over 75 years of age. Concurrently, a small increase in major bleeding events was observed. Use of catheter ablation increased continuously over the study period, but use of other rhythm-control therapies decreased after 2013. CONCLUSION: Stroke prevention with OACs in patients with incident AF improved considerably from 2007 to 2017 in Finland. This development was accompanied by decreasing 1-year mortality and the reduction of the ischaemic stroke rate by more than half, particularly among elderly patients, whereas there was only slight increase in severe bleeding events.

AIMS: Little is known about rural-urban differences in the treatment and outcomes in patients with atrial fibrillation (AF). 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.

Background: Low socioeconomic status has been associated with higher risk of ischemic stroke and death in patients with atrial fibrillation (AF). However, whether socioeconomic status affects risk of bleeding events is unknown. We assessed the hypothesis that low income and educational attainment are associated with higher risk of bleeding in patients with AF. Methods: The registry-based FinACAF study covers all patients with AF in Finland during 2007-2018. Patients were divided into income quartiles and three categories based on their educational attainment. Outcomes of interest were the first-ever gastrointestinal (GI), intracranial (IC) and any bleeding. Results: We identified 205 019 patients (50.9 % female; mean age 72.3 (SD 13.4) years) with incident AF without prior bleeding. Mean follow-up time was 4.0 (SD 3.2) years, during which 25 013 (12.2 %) patients experienced first-ever any bleeding (incidence rate 3.07 (95 % CI 3.03-3.10) /100 patient-years). Low income was independently associated with hazard of any bleeding as well as GI and IC bleeding (adjusted hazard ratios (HRs) comparing lowest vs highest income quartile: 1.13 (1.08-1.17), 1.32 (1.23-1.41) and 1.15 (1.06-1.24), respectively). Income-related bleeding disparities were larger among younger patients under 65 years and among men. Education-related bleeding disparities were smaller than income related-disparities (adjusted HRs comparing lowest vs highest educational category: any bleeding 1.06 (1.02-1.11), GI bleeding 1.16 (1.08-1.24), IC bleeding 1.10 (0.93-1.09)). Conclusions: Patients with AF and low income are at higher risk of bleeding, especially GI bleeding.
