Background: Semaglutide, a glucagon-like peptide-1 receptor agonist, is reported to have cardiac benefits, but its effects on preventing atrial fibrillation (AF) remain inconclusive. This study aimed to investigate whether semaglutide can prevent AF occurrence in patients with type 2 diabetes mellitus (T2DM), obesity, or overweight., Methods: We searched MEDLINE, EMBASE, the Cochrane CENTRAL database, and clinicaltrials.gov from inception to December 29, 2023. Randomized controlled trials of semaglutide in patients with T2DM, obesity, or overweight were included. The primary outcome was AF occurrence. Relative risks (RRs) with 95 % confidence intervals (CIs) were calculated for the overall population and subgroups., Results: Twenty-one trials comprising 25957 patients were included. In the overall pooled analysis, semaglutide decreased AF occurrence compared to control drugs (RR 0.70, 95 % CI 0.52-0.95). This result was consistent in trials using other antihyperglycemic medications as controls (RR 0.43, 95 % CI 0.21-0.89), but not in placebo-controlled trials (RR 0.77, 95 % CI 0.56-1.07). The outcome was favorable for patients with T2DM (RR 0.71, 95 % CI 0.52-0.97), but not for patients with overweight or obesity (RR 0.56, 95 % CI 0.18-1.73). Results varied by type of semaglutide, with oral semaglutide showing an RR of 0.49 (95 % CI 0.25-0.97) and subcutaneous semaglutide showing an RR of 0.77 (95 % CI 0.55-1.07)., Conclusion: Semaglutide was associated with a reduced risk of AF occurrence in the overall analysis. Favorable outcomes were observed in subsets using other antihyperglycemic medications as controls, in patients with T2DM, and with oral semaglutide., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Research Trust of DiabetesIndia (DiabetesIndia) and National Diabetes Obesity and Cholesterol Foundation (N-DOC).

Aims: Sodium-glucose co-transporter-2 (SGLT2) inhibitors are reported to have cardiac benefits. The effects of SGLT2 inhibitors on the prevention of atrial fibrillation (AF) remain inconclusive. We aimed to investigate whether SGLT2 inhibitors can prevent AF occurrence in patients with cardiometabolic diseases., Methods and Results: We searched MEDLINE, EMBASE, and the Cochrane CENTRAL database up to 1 July 2023. Randomized, placebo-controlled trials of SGLT2 inhibitors in patients with diabetes, heart failure, chronic kidney diseases (CKDs), or cardiometabolic risk factors were included. The primary outcome was AF occurrence. Relative risks (RRs) with 95% confidence intervals (CIs) were calculated in the overall population and selected subgroups. Forty-six trials comprising 101 100 patients were included. Overall, no significant risk reduction of AF occurrence was observed with SGLT2 inhibitors, although there was a favourable trend (RR 0.90, 95% CI 0.80-1.01). In trials with follow-up durations of over 1 year, a similar result was achieved (RR 0.90, 95% CI 0.80-1.01). The results were consistent across different SGLT2 inhibitors, with RRs (95% CIs) of 0.82 (0.60-1.12) for canagliflozin, 0.87 (0.73-1.03) for dapagliflozin, 0.97 (0.78-1.22) for empagliflozin, 0.99 (0.66-1.50) for sotagliflozin, and 0.87 (0.58-1.29) for ertugliflozin. Analyses in different doses of SGLT2 inhibitors yielded similar results. The associations between SGLT2 inhibitors and AF occurrence were also absent in patients with diabetes, heart failure, and CKDs., Conclusion: For patients with cardiometabolic diseases or risk factors, SGLT2 inhibitors did not decrease the risk of AF occurrence, regardless of follow-up duration, type or dose of the drug, or the patient population., Competing Interests: Conflict of interest: H.-D.Z., L.D., Y.-J.S., and M.T. take responsibility for the content of the manuscript, including the data and analysis., (© The Author(s) 2023.

Abstract Background The interplay between atrial fibrillation (AF) and obesity on mortality in critically ill patients warrants detailed exploration, given their individual impacts on patient prognosis. This study aimed to assess the associations between AF, obesity, and 1-year mortality in a critically ill population. Methods Utilizing data from the Medical Information Mart for Intensive Care (MIMIC)-IV database, we conducted a retrospective analysis of adult patients admitted to the intensive care unit. The primary endpoint was 1-year mortality, analyzed through Cox regression with hazard ratio (HR) and Kaplan-Meier survival methods. Results The study included 25,654 patients (median age 67.0 years, 40.6% female), with 39.0% having AF and 36.1% being obese. Multivariate COX regression analysis revealed that AF was associated with a 14.7% increase in the risk of 1-year mortality (p

Background: The interplay between atrial fibrillation (AF) and obesity on mortality in critically ill patients warrants detailed exploration, given their individual impacts on patient prognosis. This study aimed to assess the associations between AF, obesity, and 1-year mortality in a critically ill population. Methods: Utilizing data from the Medical Information Mart for Intensive Care (MIMIC)-IV database, we conducted a retrospective analysis of adult patients admitted to the intensive care unit. The primary endpoint was 1-year mortality, analyzed through Cox regression with hazard ratio (HR) and Kaplan-Meier survival methods. Results: The study included 25,654 patients (median age 67.0 years, 40.6% female), with 39.0% having AF and 36.1% being obese. Multivariate COX regression analysis revealed that AF was associated with a 14.7% increase in the risk of 1-year mortality (p < 0.001), while obesity was linked to a 13.9% reduction in mortality risk (p < 0.001). The protective effect of obesity on mortality was similar in patients with (HR = 0.85) and without AF (HR = 0.86). AF led to a slightly higher risk of mortality in patients without obesity (HR = 1.16) compared to those with obesity (HR = 1.13). Kaplan-Meier survival curves highlighted that non-obese patients with AF had the lowest survival rate, whereas the highest survival was observed in obese patients without AF. Conclusions: AF significantly increased 1-year mortality risk in critically ill patients, whereas obesity was associated with a decreased mortality risk. The most adverse survival outcomes were identified in non-obese patients with AF. [ABSTRACT FROM AUTHOR]
