Association Between Insulin Resistance and Incomplete Endothelization of LAAC Devices in Patients with Atrial Fibrillation: A Retrospective Study.
Introduction: Incomplete endothelialization (IDE) of left atrial appendage closure (LAAC) devices increases the risk of device-related thrombosis (DRT) and stroke. Insulin resistance (IR) may contribute to IDE by impairing endothelial function, but its role remains unclear. This study aimed to investigate the association between IR markers and IDE and develop a predictive model for identifying high-risk patients.
Methods: This retrospective observational study included 168 patients with nonvalvular atrial fibrillation (AF) who underwent successful LAAC at Shanghai Ninth People's Hospital between January 2022 and December 2023. IDE was assessed using transesophageal echocardiography (TEE) and cardiac computed tomography angiography (CCTA) at 6 months post-procedure. IR was evaluated using the triglyceride-glucose (TyG) index, triglyceride-to-high-density lipoprotein cholesterol (TG/HDL-c) ratio, and metabolic score for insulin resistance (METs-IR). Logistic regression analysis was performed to identify independent predictors of IDE, and a predictive model was constructed.
Results: Among the 168 patients included in the analysis, 43 (25.5%) exhibited IDE, as determined by TEE or CCTA at 6 months post-procedure. Patients with IDE had a significantly higher body mass index, triglyceride (TG) levels, total TG/high-density lipoprotein ratio, TyG index, METs-IR index, and D-dimer levels, as well as a larger maximum LAA orifice diameter (p < 0.05). Multivariate logistic regression identified D-dimer, METs-IR, and maximum LAA orifice diameter as independent predictors of IDE. The predictive probability model incorporating these factors demonstrated high discriminatory ability (area under the curve 0.800, 95% confidence interval 0.71-0.89, p < 0.0001). The optimal predicted probability cut-off value was 0.284, achieving a sensitivity of 76.2% and a specificity of 85.2%.
Conclusion: IR markers, D-dimer levels, and LAA orifice size are significant predictors of IDE following LAAC. The logistic regression model proposed here provides an effective risk stratification tool for identifying patients at higher risk for IDE, enabling personalized anticoagulation strategies and optimizing post-procedural management. Future research should explore whether metabolic interventions can enhance endothelialization and improve long-term outcomes in patients undergoing LAAC.
期刊介绍：
Aims and Scope
Cardiology and Therapy is an international, open access, peer reviewed (single-blind), rapid-publication journal dedicated to the publication of high-quality clinical (all phases), observational, real-world, and health outcomes research around the discovery, development, and use of cardiovascular therapies and interventions, including devices. Studies relating to diagnosis and diagnostics, pharmacoeconomics, public health, quality of life, as well as patient care, management and education are also encouraged.
Areas of focus include, but are not limited to, ischaemic heart disease and acute cardiac care, myocardial, valvular, pericardial and congenital heart disease, vascular and pulmonary disease (including hypertension), arrhythmias, heart failure, non-invasive diagnostic techniques, and invasive and interventional cardiology as well as cardiovascular surgery.
The journal is of interest to a broad audience of pharmaceutical and healthcare professionals and publishes original research, reviews, case reports/case series, trial protocols and short communications such as commentaries and editorials. Cardiolology and Therapy will consider all scientifically sound research be it positive, confirmatory or negative data. Submissions are welcomed whether they relate to an international and/or a country-specific audience, something that is crucially important when researchers are trying to target more specific patient populations. This inclusive approach allows the journal to assist in the dissemination of quality research, which may be considered of insufficient interest by other journals.
Rapid Publication
The journal’s publication timelines aim for a rapid peer review of 2 weeks. If an article is accepted it will be published 3–4 weeks from acceptance. The rapid timelines are achieved through the combination of a dedicated in-house editorial team, who manage article workflow, and an extensive Editorial and Advisory Board who assist with peer review. This allows the journal to support the rapid dissemination of research, whilst still providing robust peer review. Combined with the journal’s open access model this allows for the rapid, efficient communication of the latest research and reviews, fostering the advancement of cardiovascular therapies.
Personal Service
The journal’s dedicated in-house editorial team offer a personal “concierge service” meaning authors will always have an editorial contact able to update them on the status of their manuscript. The editorial team check all manuscripts to ensure that articles conform to the most recent COPE, GPP and ICMJE publishing guidelines. This supports the publication of ethically sound and transparent research.
Digital Features and Plain Language Summaries
Cardiology and Therapy offers a range of additional features designed to increase the visibility, readership and educational value of the journal’s content. Each article is accompanied by key summary points, giving a time-efficient overview of the content to a wide readership. Articles may be accompanied by plain language summaries to assist readers who have some knowledge of, but not in-depth expertise in, the area to understand the scientific content and overall implications of the article. The journal also provides the option to include various types of digital features including animated abstracts, video abstracts, slide decks, audio slides, instructional videos, infographics, podcasts and animations. All additional features are peer reviewed to the same high standard as the article itself. If you consider that your paper would benefit from the inclusion of a digital feature, please let us know. Our editorial team are able to create high-quality slide decks and infographics in-house, and video abstracts through our partner Research Square, and would be happy to assist in any way we can. For further information about digital features, please contact the journal editor (see ‘Contact the Journal’ for email address), and see the ‘Guidelines for digital features and plain language summaries’ document under ‘Submission guidelines’.

Publication Fees
Upon acceptance of your article for publication, authors will be required to pay the mandatory Rapid Service Fee of £3650/€4500/$5100. The journal will consider fee discounts for developing countries and this is decided on a case by case basis.
Open Access
All articles published by Cardiology and Therapy are published open access.
Peer Review Process
Upon submission, manuscripts are assessed by the editorial team to ensure they fit within the aims and scope of the journal and are also checked for plagiarism. All suitable submissions are then subject to a comprehensive single-blind peer review. Reviewers are selected based on their relevant expertise and publication history in the subject area. The journal has an extensive pool of editorial and advisory board members who have been selected to assist with peer review based on the afore-mentioned criteria.
At least two extensive reviews are required to make the editorial decision, with the exception of some article types such as Commentaries, Editorials and Letters which are generally reviewed by one member of the Editorial Board. Where reviewer recommendations are conflicted, the editorial board will be contacted for further advice and a presiding decision. Manuscripts are then either accepted, rejected or authors are required to make major or minor revisions (both reviewer comments and editorial comments may need to be addressed). Once a revised manuscript is re-submitted, it is assessed along with the responses to reviewer comments and if it has been adequately revised it will be accepted for publication. Accepted manuscripts are then copyedited and typeset by the production team before online publication. Appeals against decisions following peer review are considered on a case by case basis and should be sent to the journal editor.
Preprints
We encourage posting of preprints of primary research manuscripts on preprint servers, authors’ or institutional websites, and open communications between researchers whether on community preprint servers or preprint commenting platforms. Posting of preprints is not considered prior publication and will not jeopardize consideration in our journals. Authors should disclose details of preprint posting during the submission process or at any other point during consideration in one of our journals. Once the preprint is published, it is the author’s responsibility to ensure that the preprint record is updated with a publication reference, including the DOI and a URL link to the published version of the article on the journal website.
