- Background: Chronic obstructive pulmonary disease (COPD) and infections are risk factors for venous thromboembolism (VTE), but the reasons behind the associations are not fully known. Few studies have investigated whether lung function and respiratory symptoms in individuals without COPD are associated with VTE. Objectives: To study the incidence of VTE in individuals without COPD and other major VTE risk factors, in relation to baseline lung function and respiratory symptoms, through a 44-year follow-up prospective cohort study. Methods: As part of a health screening program, a total of 20,253 men and 7361 women underwent a baseline examination from 1974 to 1992, including a spirometry test and a self-administered questionnaire about respiratory symptoms, e.g., chronic bronchitis, cough, phlegm, and dyspnoea. Lung function was assessed through quartiles of forced expiratory volume in 1 s/forced vital capacity (FEV1/FVC). Through linkage with national registers, all individuals were followed for incidence of VTE. Results: Respiratory symptoms (cough and dyspnoea) at baseline were associated with an increased risk of incident VTE in women after adjustments for age, height, BMI, smoking status, varicose veins, and FEV1/FVC. The adjusted hazard ratio in relation to chronic bronchitis was 1.57 (95% confidence interval 1.17–2.11). Poor lung function was not associated with an increased risk of VTE after adjustments for potential confounders. Conclusion: Women with respiratory symptoms of cough and dyspnoea without COPD have an increased risk of VTE, independent of lung function and major VTE risk factors. Further studies are needed to confirm the association and to study the clinical applicability of the results. © 2023 The Authors

- Background: The risk of adults with a congenital heart defect (ACHD) developing heart failure, stroke, arrhythmias, and the need for valve replacement is increased compared to healthy peers. Evidence for the use of novel oral anticoagulants (NOAC) in this patient group is still lacking and vitamin K antagonists (VKA) are the primary choice for patients with a mechanical valve. The present aim was to determine the rate of thromboembolic and major bleeding events in ACHD patients on VKA therapy. Methods: This was a retrospective study on ACHD patients on VKA treatment registered in the National Quality Registry for Congenital Heart Disease, SWEDCON, and Atrial fibrillation and Anticoagulation, AuriculA, from Southern Sweden. Results: 213 patients were included with a mean age of 50 years (±18) years and a mean follow-up of 6.6 years (±3.3 years), 16% had complex defects and 41% had valvular VKA therapy indication. In total, 34 complications were registered, of which 14 were thromboembolic events and 20 were major bleeding events. The rate of thromboembolism and major bleeding events was 1.0 (95% CI: 0.6–1.6) and 1.4 (95% CI: 0.9–2.2) per 100 patient-years, respectively. Forty-three patients died during the study period. The mortality rate was 3.1 per 100 patient-years (95% CI: 2.2–4.1). Conclusion: We found a low rate of thromboembolic events and major bleeding events for low-moderate risk ACHD patients with good quality of VKA anticoagulation. The target of TTR>65% for ACHD patients is recommended.

- Introduction: Optimal antithrombotic treatment after an acute coronary syndrome (ACS) in patients with atrial fibrillation is unclear. Data on outcomes in patients on concomitant ticagrelor and the novel oral anticoagulants (NOAC) is scarce. This study therefore sought to describe patient characteristics and treatment outcomes in patients with atrial fibrillation and ACS treated with concomitant ticagrelor and NOACs (double antithrombotic therapy, DT). Materials and methods: We retrospectively identified all ACS patients with atrial fibrillation on DT upon discharge from Skåne University Hospital in Lund, Sweden, between 2016 and 2019. Identified patients were compared with age and sex matched controls with ACS alone treated with ticagrelor and aspirin (DAPT). Major bleeding was defined in accordance with the HAS-BLED derivation study. Patients were retrospectively followed for six months. Results: In total, 341 patients on DT were identified and compared with 341 controls on DAPT. Mean HAS-BLED bleeding risk score was higher in patients on DT (2.9 ± 1.0 vs 2.6+/0.9 units, p < 0.001; DT vs DAPT). The incidence of major bleeding was higher in patients on DT (31 (9.1%) vs 10 (2.9%), p = 0.001; DT vs DAPT), while a composite of all thrombotic events was found to be similar between the groups (8 (2.3%) vs 5 (1.5%), p = NS; DT vs DAPT). Conclusions: While thrombotic events occur at a similar rate, the bleeding rate is higher in patients with atrial fibrillation and ACS treated with DT than in patients with ACS alone treated with DAPT. Patients with atrial fibrillation also have a higher basal bleeding risk.
