<p dir="ltr">Objective: This study aimed to investigate the associations between concurrent atrial fibrillation and diabetes-related complications among patients with diabetes mellitus.</p><p dir="ltr">Research Design and Methods: This nationwide observational cohort study utilized the health check-up database from the Korean National Health Insurance Service. Patients diagnosed with diabetes mellitus who underwent health check-ups between 2009 and 2012 were investigated. The patients with atrial fibrillation were matched in a 1:5 ratio with those without atrial fibrillation using propensity scores.

After well-balanced propensity-score matching, patients with atrial fibrillation were associated with significantly higher risks of macrovascular complications (HR 1.12, 95% CI 1.09–1.16), diabetic nephropathy (HR 1.23, 95% CI 1.16–1.30), and diabetic foot complications (HR 1.13, 95% CI 1.09–1.17) compared to patients without atrial fibrillation, while the risk of diabetic retinopathy was comparable (HR 0.99, 95% CI 0.96–1.03). The patients with atrial fibrillation had a significantly higher risk of diabetic foot amputation (HR 4.12, 95% CI 1.98–8.56).</p><p dir="ltr">Conclusions: Among patients with diabetes mellitus, concurrent atrial fibrillation was associated with increased risks for diabetes-related macrovascular and microvascular complications and diabetic foot complications. Such patients require holistic management to reduce the risk of adverse outcomes.</p>

China has a large population of elderly in rural areas. Village doctors are acting as health-care gatekeepers for the rural elderly in China and are encouraged to provide more long-term care for patients with chronic diseases such as atrial fibrillation (AF). The data of AF registries from the rural elderly are limited. The present registry aims to provide contemporary data on the current AF-related health status of the rural elderly and the gaps in management of AF by village doctors. This study has two phases. The first phase is a cross-sectional study of AF screening in two rural towns of eastern China. All the residents aged ≥65 years are eligible and will be invited to attend a government-led health examination or an in-house AF screening program. The AF detection rate, the awareness of AF and the usage of oral anticoagulants and smartphones by AF patients, and the ability to diagnose and manage AF by village doctors will be assessed. Participants with AF detected in the first phase are eligible for the second phase. A variety of modes of intensified education will be provided to all AF patients and their family members to enrich their AF-related knowledge. Their village doctors will be offered a lecture-based training program focusing on Atrial fibrillation Better Care (ABC) pathway. Follow-up will be conducted for 1 year. The primary endpoint is the composite of all stroke and all-cause mortality. The first phase of AF screening was conducted between April 2019 and June 2019, and 18,712 participants with the mean age of 73.1±5.8 years were enrolled. The second phase that includes 810 patients with AF, started on 1 May 2019. This study will provide a perspective of primary care system and would indirectly reflect the current status of chronic disease care in rural China.

Statin therapy in older people (aged ≥ 65 years) without CVD was associated with a 14%, 20%, and 15% lower risk of all-cause mortality, CVD death, and stroke, respectively. The beneficial association with the risk of all-cause mortality remained significant even at higher ages (> 75 years old), in both men and women, and in individuals with DM, but not in those without DM. These observational findings support the need for trials to test the benefits of statins in those above 75 years of age.

Background: Although direct oral anticoagulants (DOACs) for patients with atrial fibrillation (AF) are considered to be safe, over or under anticoagulation and increased bleeding or thromboembolic risk are still considered individually. We aimed to investigate whether there is an association between prothrombin time and international normalized ratio (PT-INR) or activated partial thromboplastin time (aPTT) ratio, and the risks of ischemic stroke/systemic embolism (IS/SE) and major bleeding among AF patients taking rivaroxaban or dabigatran. Methods: This multi-center cohort study in Taiwan included 3192 AF patients taking rivaroxaban and 958 patients taking dabigatran for stroke prevention where data about PT-INR and aPTT were available. Results: For patients treated with rivaroxaban, a higher INR level was not associated with a higher risk of major bleeding compared to an INR level < 1.1. The risk of IS/SE was lower for patients having an INR ≥ 1.5 compared to those with an INR < 1.1 (aHR:0.57; [95%CI: 0.37−0.87]; p = 0.01). On-label dosing of rivaroxaban and use of digoxin were independent factors associated with an INR ≥ 1.5 after taking rivaroxaban. For patients taking dabigatran, a higher aPTT ratio was not associated with a higher risk of major bleeding. The risk of IS/SE was lower for patients having an aPTT ratio of 1.1−1.2 and 1.3−1.4 than those with an aPTT ratio < 1.1. Conclusions: In AF patients, rivaroxaban with an INR ≥ 1.5 was associated with a lower risk of IS/SE. PT-INR or aPTT ratios were not associated with bleeding events for rivaroxaban or dabigatran. INR may help predict the outcome of AF patients who take rivaroxaban.

The use of GLP-1RAs was associated with lower rates of cardiovascular events than no use in patients with MUHO. Similar but non-statistically significant trends were seen in patients with MHO.

For patients with nonvalvular atrial fibrillation taking non-vitamin K oral anticoagulants, several concurrent medications were associated with increased risks of intracranial hemorrhage, major bleeding hospitalizations, and overall mortality.

The prediction of arrhythmia recurrences after catheter ablation of atrial fibrillation (AF) remains challenging. The aim of current analysis was to investigate the time-dependent prediction of arrhythmia recurrences after AF catheter ablation during long-term follow-up. The study included 879 patients (61 ± 10 years; 64% males; 39% persistent AF) undergoing first AF catheter ablation. Rhythm outcomes were documented using 7-days Holter monitoring. The APPLE score (Age, Persistent AF, imPaired eGFR, Left atrium (LA), EF) was calculated at baseline, while MB-LATER score (Male gender, Bundle branch block, LA, AF Type, Early Recurrences) 3 months after ablation. The median follow-up time was 37 months [95%CI 35;39]. ERAF and LRAF occurred in 45% and 64%, respectively. On multivariable analysis, ERAF (HR 2.095, 95%CI 1.762-2.490, p < 0.001) was strongly associated with LRAF. The APPLE (HR 1.385, 95%CI 1.276-1.505, p < 0.001) and MB-LATER (HR 1.326, 95%CI 1.239-1.419, p < 0.001) scores significantly predicted LRAF during follow-up. On the ROC analysis, APPLE (AUC 0.640, 95%CI 0.602-0.677, p < 0.001) and MB-LATER (AUC 0.654, 95%CI 0.616-0.691, p < 0.001) demonstrated moderate prediction. Summarizing, ERAF was the strongest predictor for LRAF in time-dependent manner. The APPLE and MB-LATER scores demonstrated moderate prediction of arrhythmia recurrences during long term follow-up.

CHIP mutations, primarily DNMT3A or TET2, are more prevalent in patients with AF than non-AF subjects whilst their presence is associated with a more progressive nature of AF and unfavourable clinical outcomes.
