Sex, age, type of diabetes and incidence of atrial fibrillation in patients with diabetes mellitus: a nationwide analysis.

ABSTRACT:

Background

There remain uncertainties regarding diabetes mellitus and the incidence of atrial fibrillation (AF), in relation to type of diabetes, and the interactions with sex and age. We investigated whether diabetes confers higher relative rates of AF in women compared to men, and whether these sex-differences depend on type of diabetes and age.

Methods

All patients aged???18 seen in French hospitals in 2013 with at least 5 years of follow-up without a history of AF were identified and categorized by their diabetes status. We calculated overall and age-dependent incidence rates, hazard ratios, and women-to-men ratios for incidence of AF in patients with type 1 and type 2 diabetes (compared to no diabetes).

Results

In 2,921,407 patients with no history of AF (55% women), 45,389 had prevalent type 1 diabetes and 345,499 had prevalent type 2 diabetes. The incidence rates (IRs) of AF were higher in type 1 or type 2 diabetic patients than in non-diabetics, and increased with advancing age. Among individuals with diabetes, the absolute rate of AF was higher in men than in women. When comparing individuals with and without diabetes, women had a higher adjusted hazard ratio (HR) of AF than men: adjusted HR 1.32 (95% confidence interval 1.27-1.37) in women vs. 1.12(1.08-1.16) in men for type 1 diabetes, adjusted HR 1.17(1.16-1.19) in women vs. 1.10(1.09-1.12) in men for type 2 diabetes.

Conclusion

Although men have higher absolute rates for incidence of AF, the relative rates of incident AF associated with diabetes are higher in women than in men for both type 1 and type 2 diabetes.

Project description:BackgroundThere are limited data on the association of diabetes mellitus (DM) and levels of glycated hemoglobin (HbA1c) with outcomes in patients with atrial fibrillation (AF).MethodsThis retrospective cohort study included patients who were recently hospitalized with a primary or secondary diagnosis of AF from December 2015 through June 2018. Kaplan-Meier curves and Cox-regression adjusted hazard ratios (aHR) were calculated for the primary outcome of all-cause mortality and for the secondary outcomes of cardiovascular (CV) mortality and the composite outcome of CV death or hospitalization. Competing-risk regression analyses were performed to calculate the cumulative risk of stroke, major bleeding, AF- or HF-hospitalizations adjusted for the competing risk of all-cause death. Spline curve models were fitted to investigate associations of HbA1c values and mortality among patients with AF and DM.ResultsIn total 1109 AF patients were included, of whom 373 (33.6%) had DM. During a median follow-up of 2.6 years, 414 (37.3%) patients died. The presence of DM was associated with a higher risk of all-cause mortality (aHR = 1.40 95% confidence intervals [CI] 1.11-1.75), CV mortality (aHR = 1.39, 95% CI 1.07-1.81), sudden cardiac death (aHR = 1.73, 95% CI 1.19-2.52), stroke (aHR = 1.87, 95% CI 1.01-3.45) and the composite outcome of hospitalization or CV death (aHR = 1.27, 95% CI 1.06-1.53). In AF patients with comorbid DM, the spline curves showed a positive linear association between HbA1c levels and outcomes, with values 7.6-8.2% being independent predictors of increased all-cause mortality, and values < 6.2% predicting significantly decreased all-cause and CV mortality.ConclusionsThe presence of DM on top of AF was associated with substantially increased risk for all-cause or CV mortality, sudden cardiac death and excess morbidity. HbA1c levels lower than 6.2% were independently related to better survival rates suggesting that optimal DM control could be associated with better clinical outcomes in AF patients with DM.

Project description:BackgroundType 2 diabetes mellitus (T2D) and heart failure (HF) are closely related to the increased risk of atrial fibrillation (AF)/atrial flutter (AFL). However, massive clinical studies have shown that sodium glucose cotransporter 2 inhibitor (SGLT2i) affects the occurrence of AF/AFL and its complications, but the promoting or inhibitory effect of SGLT2i on AF/AFL and its complications and the exact probability is not clear, meta-analysis can combine the existing research data to easily solve the clinical problems.MethodsWe performed a search in the registers of ClinicalTrials.gov from it,s inception to March 2021 to evaluate the occurrence of AF/AFL adverse events in SGLT2i in patients with T2D/HF. Almost all of the included studies were double-blind parallel allocation randomized controlled studies, and only one was open. The control groups all included placebo, some of which also included glimepiride, metformin, liraglutide, etc. Quality risk assessment of the included randomized controlled trials (RCTs) was conducted using Cochrane RoB 2.0., and the publication bias assessment was conducted using STATA 17.0. The odds ratio (OR) combined effect of 95% confidence interval (CI) was used for bivariate variables.ResultsWe included data from 22 confirmed trials that included 52,951 T2D/HF patients. The studies had no risk of bias. Analysis of the cumulative results showed that compared with placebo, SGLT2i can significantly reduce the incidence of AF/AFL by 18% (OR =0.82, 95% CI: 0.73 to 0.93, P=0.002), and reduce the incidence of arrhythmia by 14% (OR =0.86, 95% CI: 0.79 to 0.94, P=0.0006); among them, the incidence of AF/AFL in T2D patients was reduced by 20% (OR =0.80, 95% CI: 0.69 to 0.92, P=0.002); Dapagliflozin reduced the incidence of AF/AFL by 15% (OR =0.85, 95% CI: 0.74 to 0.98, P=0.03); the incidence of intracardiac thrombosis decreased by 69% (OR =0.31, 95% CI: 0.10 to 0.91, P=0.03), while the incidence of AF/AFL in women decreased by 17% (OR =0.83, 95% CI: 0.72 to 0.94, P=0.004).DiscussionThis article provides a new direction for the use of SGLT2i, and hopefully it can provide certain theoretical basis for the broader clinical indications of SGLT2i in the future.
