Relevance of the Viborg Population Based Screening Programme (VISP) for Cardiovascular Conditions Among 67 Year Olds: Attendance Rate, Prevalence, and Proportion of Initiated Cardiovascular Medicines Stratified By Sex.

OBJECTIVE: To report sex specific overall attendance rate, prevalence of screen detected cardiovascular conditions, proportion of unknown conditions before screening, and proportion initiating prophylactic medicine among 67 year olds in Denmark. DESIGN: Cross sectional cohort study. METHODS: Since 2014, all 67 year olds in Viborg, Denmark, have been invited to screening for abdominal aortic aneurysm (AAA), peripheral arterial disease (PAD), carotid plaque (CP), hypertension, cardiac disease, and type 2 diabetes. Individuals with AAA, PAD, and or CP are recommended cardiovascular prophylaxis. Combining data with registries has facilitated estimation of unknown screen detected conditions. Up to August 2019, 5 505 had been invited; registry data were available for the first 4 826 who were invited. RESULTS: The attendance rate was 83.7%, without sex difference. Screen detected prevalence was significantly lower among women than men: AAA, 5 (0.3%) vs. 38 (1.9%) (p < .001); PAD, 90 (4.5%) vs. 134 (6.6%) (p = .011); CP, 641 (31.8%) vs. 907 (44.8%) (p < .001); arrhythmia, 26 (1.4%) vs. 77 (4.2%) (p < .001); blood pressure ≥ 160/100 mmHg, 277 (13.8%) vs. 346 (17.1%) (p = .004); and HbA1c ≥ 48 mmol/mol, 155 (7.7%) vs. 198 (9.8%) (p = .019), respectively. Pre-screening proportions of unknown conditions were particularly high for AAA (95.4%) and PAD (87.5%). AAA, PAD, and or CP were found in 1 623 (40.2%), of whom 470 (29.0%) received pre-screening antiplatelets and 743 (45.8%) lipid lowering therapy. Furthermore, 413 (25.5%) started antiplatelet therapy and 347 (21.4%) started lipid lowering therapy. Only smoking was significantly associated with all vascular conditions in multivariable analysis: odds ratios (ORs) for current smoking were AAA 8.11 (95% CI 2.27 - 28.97), PAD 5.60 (95% CI 3.61 - 8.67) and CP 3.64 (95% CI 2.95 - 4.47). CONCLUSION: The attendance rate signals public acceptability for attending cardiovascular screening. Men had more screen detected conditions than women, but prophylactic medicine was started equally frequently in both sexes. Sex specific cost effectiveness follow up is warranted.

Extended anticoagulation after venous thromboembolism.

INTRODUCTION: Venous thromboembolism (VTE) carries a high risk of recurrence, and this risk is strongly related to the nature of the index event. Thus, extended anticoagulation treatment is recommended for patients with a high recurrence risk and should be considered for patients with an intermediate risk. This study aimed to provide insight into the clinical practice of extended anticoagulation for VTE patients METHODS. This was a retrospective study of VTE patients covering the period from January 2020 through June 2021. We categorised patients by their estimated risk of recurrence as low (less-than 3% per year), intermediate (3-8% per year) or high (> 8% per year). The decision to stop or extend anticoagulation was made in a multidisciplinary VTE clinic. RESULTS: A total of 343 patients were included; 315 patients were eligible for analysis. The majority of patients (58.7%) had an intermediate recurrence risk. In total 80.3% received extended treatment. The use was highest (97.9%) among patients with a high recurrence risk, whereas 82.7% with an intermediate risk and 15.2% with a low risk received extended therapy. Non-vitamin K antagonist oral anticoagulants were preferred for extended therapy (82.2%), whereas 5.1% received warfarin and 12.6% low molecular weight heparin. CONCLUSIONS: In this real-world clinic, the majority of VTE patients switched to extended treatment after initial standard anticoagulation. The role of patient and physician preference as determinants driving this decision should be investigated further. FUNDING: This study received an unrestricted grant from Bayer, which had no involvement in the study design, data collection, analysis, or manuscript preparation. TRIAL REGISTRATION: Not relevant.
