<p> </p> <p><strong>Abstract</strong></p> <p><strong>Objective: </strong>To evaluate the association between pre-diabetes and HF and the association of HF with changes in glycaemic status. </p> <p><strong>Design and Methods: </strong>Patients newly diagnosed with AF between 2015 and 2018 were divided into 3 groups (normoglycaemia, pre-diabetes, and type 2 diabetes) according to their baseline glycaemic status. The primary outcome was incident HF. Fine and Gray model was applied, with death defined as the competing event. </p> <p><strong>Results</strong>: Among 17,943 AF patients (mean age 75.5 years, 47% female), 3,711 (20.7%) had pre-diabetes and 10,127 (56.4%) had diabetes at baseline. Over a median follow-up of 4.7 years, 518 (14%) normoglycaemic, 646 (15.7%) pre-diabetic, and 1,795 (17.7%) diabetic patients developed HF. Pre-diabetes was associated with an increased risk of HF compared with normoglycaemic patients (subdistribution Hazard Ratio (SHR) =1.12, 95% confidence interval (CI): 1.03-1.22). In patients with pre-diabetes at baseline, 403 (11.1%) progressed to diabetes and 311 (8.6%) reversed to normoglycaemia at 2 years. Compared to those who remained pre-diabetic, patients who progressed to diabetes were associated with an increased risk of HF (SHR=1.50, 95% CI: 1.13-1.97), whereas those who reversed to normoglycaemia were associated with decreased risk (SHR=0.61, 95% CI: 0.42-0.94). </p> <p><strong>Conclusions</strong>: Pre-diabetes was associated with an increased risk of HF in patients with AF. Compared with patients who remained pre-diabetic, those who progressed to diabetes at 2 years experienced an increased risk of HF, whereas those who reversed to normoglycaemia incurred a lower risk of HF. </p>
Periodontitis is one of the most common inflammatory diseases worldwide, affecting over half of the population. It is a focus of chronic low-grade systemic inflammation, which is thought to contribute to the pathogenesis of cardiovascular diseases, including atrial fibrillation (AF), the most common supraventricular arrhythmia. A review of available epidemiological and pathophysiological studies, despite existing methodological limitations, indicates that individuals with moderate to severe periodontitis have a significantly higher risk of developing AF, and in patients already suffering from AF, the presence of periodontitis is associated with a poorer prognosis: a higher risk of recurrent arrhythmia, stroke, and cardiovascular events. Multiple mechanisms linking both diseases have been identified, including chronic immune activation, proinflammatory cytokines (CRP, IL-6, TNF-α), autoimmunity, atrial fibrosis, and the direct effects of oral pathogens (e.g., Porphyromonas gingivalis) on myocardial tissue. Furthermore, these diseases share many risk factors: obesity, diabetes, smoking, and low socioeconomic status. Scientific evidence indicates that periodontal treatment (scaling, periodontal therapy, improved oral hygiene) significantly reduces inflammatory markers and the risk of AF. The authors propose that oral health be considered as part of integrated care for patients with AF (ABC pathway). Despite the growing body of evidence, current cardiology guidelines do not address the role of periodontitis, indicating the need for updated standards of care. This narrative review summarizes the current knowledge regarding the relationship between periodontitis and AF.
The observed incidence of stroke or systemic embolism and major bleeding events generally conformed to an expected increasing incidence by risk score, adding insight into the importance of specific risk score range, thromboembolic event history, and age group strata. These results can help inform clinical decision-making, research, and policy.
