The Impact

Abstract Aims Data on the impact of liver disease (LD) in patients with atrial fibrillation (AF) and the role of oral anticoagulant (OAC) drugs for stroke prevention, are limited. We analysed the impact of LD and OAC treatment in determining stroke, major bleeding, all-cause death and secondary bleeding outcomes. Methods A retrospective observational population-based cohort study. The study cohort is derived from the administrative health databases of Lombardy region (>10 million inhabitants), Italy. All AF patients ≥40 years admitted to hospital from 2000 to 2018 were considered. AF and LD diagnosis were established using ICD9-CM codes. Use of OAC was determined with Anatomical Therapeutic Chemical (ATC) codes. Primary study outcomes were stroke, major bleeding and all-cause death. Results Among 393,507 AF patients, 16,168 (4.1%) had concomitant LD. LD AF patients were significantly less treated with OAC independent of associated clinical characteristics (OR: 0.96, 95% CI: 0.92–0.98). Concomitant LD was found associated with an increased risk in all the study outcomes (HR: 1.18, 95% CI: 1.11–1.25 for stroke; HR: 1.57, 95% CI: 1.47–1.66 for major bleeding; HR: 1.41, 95% CI: 1.39–1.44 for all-cause death. Use of OAC in patients with AF and LD resulted in a reduction in stroke (HR: 0.80, 95% CI: 0.70–0.92), major bleeding (HR: 0.86, 95% CI: 0.74–0.99) and all-cause death (HR: 0.85, 95% CI: 0.80–0.90), with similar results according to several clinically relevant subgroups. A net clinical benefit (NCB) analysis suggested a positive benefit/risk ratio in using OAC in AF patients with LD (NCB: 0.408, 95% CI: 0.375–0.472). Conclusions In AF patients, concomitant LD carries a significantly higher risk for all clinical outcomes. Use of OAC in AF patients with LD was associated with a significant benefit/risk ratio, even in high-risk patient subgroups. Funding Acknowledgement Type of funding source: None

Abstract Aims  Data on the impact of liver disease (LD) in patients with atrial fibrillation (AF) and the role of oral anticoagulant (OAC) drugs for stroke prevention are limited. Methods and results  A retrospective observational population-based cohort study on the administrative health databases of Lombardy region Italy. All AF patients ≥40 years admitted to hospital from 2000 to 2018 were considered. Atrial fibrillation and LD diagnosis were established using ICD9-CM codes. Use of OAC was determined with Anatomical Therapeutic Chemical codes. Primary study outcomes were stroke, major bleeding, and all-cause death. Among 393 507 AF patients, 16 168 (4.1%) had concomitant LD. Liver disease AF patients were significantly less treated with OAC. Concomitant LD was associated with an increased risk in all the study outcomes [hazard ratio (HR): 1.18, 95% confidence interval (CI): 1.11–1.25 for stroke; HR: 1.57, 95% CI: 1.47–1.66 for major bleeding; HR: 1.41, 95% CI: 1.39–1.44 for all-cause death]. Use of OAC in patients with AF and LD resulted in a reduction in stroke (HR: 0.80, 95% CI: 0.70–0.92), major bleeding (HR: 0.86, 95% CI: 0.74–0.99), and all-cause death (HR: 0.77, 95% CI: 0.73–0.80), with similar results according to subgroups. A net clinical benefit (NCB) analysis suggested a positive benefit/risk ratio in using OAC in AF patients with LD (NCB: 0.408, 95% CI: 0.375–0.472). Conclusion In AF patients, concomitant LD carries a significantly higher risk for all clinical outcomes. Use of OAC in AF patients with LD was associated with a significant favourable benefit/risk ratio, even in high-risk patient subgroups.

All Cause Mortality

Objective Several studies have shown an increased risk for cardiovascular disease (CVD) in hyperthyroidism, but most studies have been too small to address the effect of hyperthyroidism on individual cardiovascular endpoints. Our main aim was to assess the association among hyperthyroidism, acute cardiovascular events and mortality. Design It is a nationwide population-based cohort study. Data were obtained from the Danish Civil Registration System and the Danish National Patient Registry, which covers all Danish hospitals. We compared the rate of all-cause mortality as well as venous thromboembolism (VTE), acute myocardial infarction (AMI), ischemic and non-ischemic stroke, arterial embolism, atrial fibrillation (AF) and percutaneous coronary intervention (PCI) in the two cohorts. Hazard ratios (HR) with 95% confidence intervals (95% CI) were estimated. Results The study included 85 856 hyperthyroid patients and 847 057 matched population-based controls. Mean follow-up time was 9.2 years. The HR for mortality was highest in the first 3 months after diagnosis of hyperthyroidism: 4.62, 95% CI: 4.40–4.85, and remained elevated during long-term follow-up (>3 years) (HR: 1.35, 95% CI: 1.33–1.37). The risk for all examined cardiovascular events was increased, with the highest risk in the first 3 months after hyperthyroidism diagnosis. The 3-month post-diagnosis risk was highest for atrial fibrillation (HR: 7.32, 95% CI: 6.58–8.14) and arterial embolism (HR: 6.08, 95% CI: 4.30–8.61), but the risks of VTE, AMI, ischemic and non-ischemic stroke and PCI were increased also 2- to 3-fold. Conclusions We found an increased risk for all-cause mortality and acute cardiovascular events in patients with hyperthyroidism.

First Choice

ObjectiveUnlike several other national health agencies, French health authorities recommended that the newer direct oral anticoagulant (DOAC) agents only be prescribed as second choice for the treatment of newly diagnosed non-valvular atrial fibrillation (NVAF), with vitamin K antagonists (VKA) remaining the first choice. We investigated the patterns of use of DOACs versus VKA in the treatment of NVAF in France over the first 5 years of DOAC availability. We also identified the changes in patient characteristics of those who initiated DOAC treatment over this time period.MethodsBased on the French National Health Administrative Database, we constituted a population-based cohort of all patients who were newly treated for NVAF between January 2011 and December 2015. Trends in drug use were described as the percentage of patients initiating each drug at the time of treatment initiation. A multivariate analysis using logistic regression model was performed to identify independent sociodemographic and clinical predictors of initial anticoagulant choice.ResultsThe cohort comprised 814 446 patients who had received a new anticoagulant treatment for NVAF. The proportion of patients using DOACs as initial anticoagulant therapy reached 54% 3 months after the Health Ministry approved the reimbursement of dabigatran for NVAF, and 61% by the end of 2015, versus VKA use. In the multivariate analysis, we found that DOAC initiators were younger and healthier overall than VKA initiators, and this tendency was reinforced over the 2011–2014 period. DOACs were more frequently prescribed by cardiologists in 2012 and after (adjusted OR in 2012: 2.47; 95% CI 2.40 to 2.54).ConclusionDespite recommendations from health authorities, DOACs have been rapidly and massively adopted as initial therapy for NVAF in France. Observational studies should account for the fact that patients selected to initiate DOAC treatment are healthier overall, as failure to do so may bias the risk–benefit assessment of DOACs.
