Aims: Atrial fibrillation/atrial flutter (AF/AFL) remains a significant public health concern on a global scale, with metabolic risks playing an increasingly prominent role. This study aimed to investigate comprehensive epidemiological data and trends concerning the metabolic risks related-AF/AFL burden based on the data from the Global Burden of Disease study in 2019.

Methods and results: The analysis of disease burden focused on numbers, age-standardized rates of deaths, disability-adjusted life years (DALYs), and estimated annual percentage change, while considering factors of age, sex, sociodemographic index (SDI), and locations. In 2019, there was a culmination of 137 179 deaths and 4 099 146 DALYs caused by metabolic risks related-AF/AFL worldwide, with an increase of 162.95% and 120.30%, respectively from 1990. High and high-middle SDI regions predominantly carried the burden of AF/AFL associated with metabolic risks, while a shift towards lower SDI regions had been occurring. Montenegro had the highest recorded death rate (7.6 per 100 000) and DALYs rate (146.3 per 100 000). An asymmetrically inverted V-shaped correlation was found between SDI and deaths/DALYs rates. Moreover, females and the elderly exhibited higher AF/AFL burdens, and young adults (over 40 years old) also experienced an annual increase.

Conclusion: The global AF/AFL burden related to metabolic risks has significantly increased over the past three decades, with considerable spatiotemporal, gender-based, and age-related heterogeneity. These findings shed valuable light on the trends in the burden of metabolic risks related-AF/AFL and offered insights into corresponding strategies.

Aims: The European Unified Registries On Heart Care Evaluation and Randomized Trials (EuroHeart) aims to improve the quality of care and clinical outcomes for patients with cardiovascular disease. The collaboration of acute coronary syndrome/percutaneous coronary intervention (ACS/PCI) registries is operational in seven vanguard European Society of Cardiology member countries.

Methods and results: Adults admitted to hospitals with ST-elevation myocardial infarction (STEMI) and non-ST-elevation myocardial infarction (NSTEMI) are included, and individual patient-level data collected and aligned according to the internationally agreed EuroHeart data standards for ACS/PCI. The registries provide up to 155 variables spanning patient demographics and clinical characteristics, in-hospital care, in-hospital outcomes, and discharge medications. After performing statistical analyses on patient data, participating countries transfer aggregated data to EuroHeart for international reporting. Between 1st January 2022 and 31st December 2022, 40 021 admissions (STEMI 46.7%, NSTEMI 53.3%) were recorded from 192 hospitals in the seven vanguard countries: Estonia, Hungary, Iceland, Portugal, Romania, Singapore, and Sweden. The mean age for the cohort was 67.9 (standard deviation 12.6) years, and it included 12 628 (31.6%) women.

Conclusion: The EuroHeart collaboration of ACS/PCI registries prospectively collects and analyses individual data for ACS and PCI at a national level, after which aggregated results are transferred to the EuroHeart Data Science Centre. The collaboration will expand to other countries and provide continuous insights into the provision of clinical care and outcomes for patients with ACS and undergoing PCI. It will serve as a unique international platform for quality improvement, observational research, and registry-based clinical trials.

Background: Significant knowledge gaps remain regarding the heterogeneity of heart failure (HF) phenotypes, particularly among patients with preserved or mildly reduced left ventricular ejection fraction (HFp/mrEF). Our aim was to identify HF subtypes within the HFp/mrEF population.

Methods: K-prototypes clustering algorithm was used to identify different HF phenotypes in a cohort of 2 570 patients diagnosed with HFmrEF or HFpEF. This algorithm employs the k-means algorithm for quantitative variables and k-modes for qualitative variables.

Results: We identified three distinct phenotypic clusters: Cluster A (n = 850, 33.1%), characterized by a predominance of women with low comorbidity burden; Cluster B (n = 830, 32.3%), mainly women with diabetes mellitus and high comorbidity; and Cluster C (n = 890, 34.5%), primarily men with a history of active smoking and respiratory comorbidities. Significant differences were observed in baseline characteristics and one-year mortality rates across the clusters: 18% for Cluster A, 33% for Cluster B, and 26.4% for Cluster C (P < 0.001). Cluster B had the shortest median time to death (90 days), followed by Clusters C (99 days) and A (144 days) (P < 0.001). Stratified Cox regression analysis identified age, cancer, respiratory failure, and laboratory parameters as predictors of mortality.

Conclusion: Cluster analysis identified three distinct phenotypes within the HFp/mrEF population, highlighting significant heterogeneity in clinical profiles and prognostic implications. Women were classified into two distinct phenotypes: low-risk women and diabetic women with high mortality rates, while men had a more uniform profile with a higher prevalence of respiratory disease.

Background: Educational attainment in children with congenital heart disease (CHD) within the UK has not been reported, despite the possibility of school absences and disease-specific factors creating educational barriers.

Methods and results: Children were prospectively recruited to the Born in Bradford birth cohort between March 2007 and December 2010. Diagnoses of CHD were identified through linkage to the congenital anomaly register and independently verified by clinicians. Multivariable regression accounted for relevant confounders. Our primary outcome was the odds of 'below expected' attainment in maths, reading, and writing at ages 4-11 years.Educational records of 139 children with non-genetic CHD were compared with 11 188 age-matched children with no major congenital anomaly. Children with CHD had significantly higher odds of 'below expected' attainment in maths at age 4-5 years [odds ratio (OR) 1.64, 95% confidence interval (CI) 1.07-2.52], age 6-7 (OR 2.03, 95% CI 1.32-3.12), and age 10-11 (OR 2.28, 95% CI 1.01-5.14). Odds worsened with age, with similar results for reading and writing. The odds of receiving special educational needs support reduced with age for children with CHD relative to controls [age 4-5: OR 4.84 (2.06-11.40); age 6-7: OR 3.65 (2.41-5.53); age 10-11: OR 2.73 (1.84-4.06)]. Attainment was similar for children with and without exposure to cardio-pulmonary bypass. Lower attainment was strongly associated with the number of pre-school hospital admissions.

Conclusion: Children with CHD have lower educational attainment compared with their peers. Deficits are evident from school entry and increase throughout primary school.

Aims: To estimate sick leave (SL) duration after first-time elective open-heart surgery and identify factors contributing to increased SL.

Methods and results: A retrospective nationwide cohort study combined data from the Norwegian Register for Cardiac Surgery and SL data from the Norwegian Labour and Welfare Administrations. All able-bodied adults who underwent first-time elective open-heart surgery in Norway between 2012 and 2021 were followed until 1 year after surgery. The impact of socio-demographic and clinical factors on SL after surgery was analysed using logistic regression and odds ratios. Of 5456 patients, 1643 (30.1%), 1798 (33.0%), 971 (17.8%), 1035 (18.9%), and 9 (0.2%) had SL of <3, 3-6, 6-9, and 9-12 months, and 1 year, respectively. SL >6 months was associated with female gender, primary education only, and average annual income. Post-operative stroke, post-operative renal failure, New York Heart Association Functional Classification system (NYHA) score >3, earlier myocardial infarction, and diabetes mellitus increased the odds of SL >6 months.

Conclusion: This study demonstrates that socio-demographic and clinical factors impact SL after first-time elective open-heart surgery. Patients who experience a stroke or develop renal failure after surgery have the highest odds of SL >6 months. Females and patients with low education levels, earlier myocardial infarction, or NYHA scores III-IV have a two-fold chance of SL >6 months. The findings allow for future investigations of pre- and post-surgery interventions that can most effectively reduce SL and aid return to work.

Aims: Update data regarding the atrial fibrillation (AF)-related mortality trend in Europe remain scant. We assess the age- and sex-specific trends in AF-related mortality in the European states between the years 2008 and 2019.

Methods and results: Data on cause-specific deaths and population numbers by sex for European countries were retrieved through the publicly available World Health Organization mortality dataset for the years 2008-2019. Atrial fibrillation-related deaths were ascertained when the International Classification of Diseases, 10th Revision code I48 was listed as the underlying cause of death in the medical death certificate. To calculate annual trends, we assessed the average annual % change (AAPC) with relative 95% confidence intervals (CIs) using Joinpoint regression. During the study period, 773 750 AF-related deaths (202 552 males and 571 198 females) occurred in Europe. The age-adjusted mortality rate (AAMR) linearly increased from 12.3 (95% CI: 11.2-12.9) per 100 000 population in 2008 to 15.3 (95% CI: 14.7-15.7) per 100 000 population in 2019 [AAPC: +2.0% (95% CI: 1.6-3.5), P < 0.001] with a more pronounced increase among men [AAPC: +2.7% (95% CI: 1.9-3.5), P < 0.001] compared with women [AAPC: +1.7% (95% CI: 1.1-2.3), P < 0.001] (P for parallelism 0.01). Higher AAMR increases were observed in some Eastern European countries such as Latvia, Lithuania, and Poland, while the lower increases were mainly clustered in Central Europe.

Conclusion: Over the last decade, the age-adjusted AF-related mortality has increased in Europe, especially among males. Disparities still exist between Western and Eastern European countries.

Background and aims: The healthcare burden of acute chest pain is enormous. In the randomized ARTICA trial, we showed that pre-hospital identification of low-risk patients and rule-out of non-ST-segment elevation acute coronary syndrome (NSTE-ACS) with point-of-care (POC) troponin measurement reduces 30-day healthcare costs with low major adverse cardiac events (MACE) incidence. Here we present the final 1-year results of the ARTICA trial.

Methods: Low-risk patients with suspected NSTE-ACS were randomized to pre-hospital rule-out with POC troponin measurement or emergency department (ED) transfer. Primary 1-year outcome was healthcare costs. Secondary outcomes were safety, quality of life (QoL), and cost-effectiveness. Safety was defined as a 1-year MACE consisting of ACS, unplanned revascularization, or all-cause death. QoL was measured with EuroQol-5D-5L questionnaires. Cost-effectiveness was defined as 1-year healthcare costs difference per QoL difference.

Results: Follow-up was completed for all 863 patients. Healthcare costs were significantly lower in the pre-hospital strategy (€1932 ± €2784 vs. €2649 ± €2750), mean difference €717 [95% confidence interval (CI) €347 to €1087; P < 0.001]. In the total population, the 1-year MACE rate was comparable between groups [5.1% (22/434) in the pre-hospital strategy vs. 4.2% (18/429) in the ED strategy; P = 0.54]. In the ruled-out ACS population, 1-year MACE remained low [1.7% (7/419) vs. 1.4% (6/417)], risk difference 0.2% (95% CI -1.4% to 1.9%; P = 0.79). QoL showed no significant difference between strategies.

Conclusions: Pre-hospital rule-out of NSTE-ACS with POC troponin testing in low-risk patients is cost-effective, as expressed by a sustainable healthcare cost reduction and no significant effect on QoL. One-year MACE remained low for both strategies.
