Abstract 4119535: Aspirin Use and Cardiovascular Disease Incidence in Adults with High Lipoprotein(a): A Multi-Cohort Study
Circulation, Volume 150, Issue Suppl_1, Page A4119535-A4119535, November 12, 2024. Introduction:There is an active debate about who may benefit from taking aspirin to reduce their incidence of cardiovascular disease (CVD). Some prior cohort studies with small sample size suggest that aspirin use may be associated with a lower incidence of CVD or coronary heart disease (CHD) in adults with Lp(a) ≥50 mg/dL but not in those with Lp(a)
Abstract 4136900: Left-to-right ventricular volume ratio as a predictor of cardiovascular events: The Multi-Ethnic Study of Atherosclerosis (MESA)
Circulation, Volume 150, Issue Suppl_1, Page A4136900-A4136900, November 12, 2024. Background:The left ventricle (LV) and right ventricle (RV) are closely connected anatomically and functionally. Therefore, relative volume alterations signify pathologic disequilibrium even when within the normal range for chamber volumes. We aimed to define the prognostic value of volumetric imbalance between the LV and RV in the general population.Methods:The study sample consisted of 4073 asymptomatic participants from the Multi-Ethnic Study of Atherosclerosis who had a cardiac MRI at baseline. The left to right ventricular volume ratio (LRVR) was defined as LV volume/RV volume at end diastole. LRVR was categorized into balanced reference category 0.8-1.3, low (RV predominance) 1.3. Multivariable cox regression models were used to study the association between LRVR and heart failure (HF), atrial fibrillation (AF), and death.Results:The mean age of participants was 61.3±10 years, with 52% females. Participants were followed for a median of 17.8 years for HF, 16.7 years for AF, and 17.1 years for death. During follow up, 239 (5.9%) participants developed HF, 772 (19%) developed AF, and 906 (22.2%) died. When compared with the reference balanced LRVR group, those with high LRVR had increased risk of HF (HR 2.55; 95% CI 1.7-3.8; p

Introduction:Transcatheter edge-to-edge repair of the mitral valve with the MitraClip has offered a less invasive percutaneous alternative to surgical repair in select candidates with mitral regurgitation. Various factors impact the outcomes of MitraClip. We investigated the impact of nutritional status on the outcomes of MitraClip.Methods:Utilizing the nationwide inpatient sample data for years from January 1, 2016, and December 31, 2021, patients who underwent MitraClip were identified. They were categorized based on obesity and protein energy malnutrition (PEM). Statistical significance was assigned at p
Abstract 4144555: Atrial Fibrillation Catheter Ablation among Patients with Mediastinal Radiation; Insight from The National Inpatient Database (2015-2020)
Circulation, Volume 150, Issue Suppl_1, Page A4144555-A4144555, November 12, 2024. Introduction/Background:Radiation therapy (RT) is one of the most common treatment modalities for mediastinal cancers. RT has multiple adverse cardiovascular effects and it has been identified as an independent risk factor for atrial fibrillation (AF). The efficacy of catheter ablation in AF is well established, however there is limited data on procedural safety and outcomes in patients with mediastinal cancers and history of radiationMethods:The National Inpatient Sample (NIS) was analyzed from 2015-2020 to identify admissions for AF catheter ablation among patients with previous history of mediastinal radiation exposure using the 10-PCS (International Classification of Diseases, procedure coding system) codes. Baseline characteristics were compared between the two groups and multivariate logistic regression was used to analyze hospitalization outcomes.Results:We identified 257,240 admissions for AF catheter ablation of which 1720 patients (0.67%) had a history of mediastinal radiation exposure. In the adjusted analysis, the odds of in-hospital mortality (aOR 0.639, 95% CI 0.34-1.20, p 0.1637), major complications (aOR 0.876, 95% CI 0.73-1.05, p 0.1443), any gastrointestinal or hematological complication (aOR 0.853, 95% CI 0.63-1.15, p 0.3017), renal complications (aOR 1.017, 95% CI 0.88-1.18, p 0.0509) were similar in both cohorts. The odds of any cardiovascular complication (aOR 0.825, 95% CI 0.70-0.97, p 0.0208) was lower and odds of any pulmonary complication (aOR 1.433, 95% CI 1.27-1.62, p
Abstract 4131228: Where Adults with Advanced Heart Failure Die: Insights from the CDC-WONDER Database
Circulation, Volume 150, Issue Suppl_1, Page A4131228-A4131228, November 12, 2024. Background:Adults with heart failure (HF) are becoming more and more prevalent. The location of death and related disparities in these patients are poorly understood.Aim:The purpose of the study was to look at the locations of adult deaths from HF and identify any age, race, or ethnicity-related variations over a 25-year period.Methods:The Centers for Disease Control and Prevention Wide-ranging Online Data for Epidemiologic Research Database provided death certificate data and the National Center for Health Statistics provided individual-level mortality data for the trend-level analysis of adults aged (20-64 and 65+ years) conducted from 1999-2023. Hospital, home, hospice and nursing home/long-term care were the categories for the places of death.Results:Between 1999 and 2023, a total of 7,644,759 adult deaths from HF were recorded (87.9% White, 53.4% female). HF-related deaths decreased from 1999 (3.60% and 143.6 AAMR) to 2010 (3.47% and 123.1 AAMR). From 2010 onwards, a gradual rise is seen, with the rate of HF deaths reaching 5.18% and 168.1 AAMR in 2023. Notably, deaths at home increased from 18.41% (50,648 of 275,132) in 1999 to 33.47% (132,470 of 395,826) in 2023 and deaths in hospice/nursing homes increased from 30.95% (85,144 of 275,132) in 1999 to 34.71% (116,634 of 336,014) in 2017 and then sudden fall was observed until 2023 to 29.54% (116,931 of 395,826). Older adults (65+) were more likely to die in inpatient facilities. Gender, ethnicity, and urbanization influenced the place of death, with males, whites, and those residing in large metropolitan areas more likely to die in medical facilities.Conclusion:Prioritize end-of-life planning for HF patients with poor prognosis, regardless of age, to improve quality of life and death.
Abstract 4143225: Carotid Artery Ultrasound Grayscale and Incident Dementia: The Multi-Ethnic Study of Atherosclerosis (MESA)
Circulation, Volume 150, Issue Suppl_1, Page A4143225-A4143225, November 12, 2024. Introduction:Vascular contributions to cognitive impairment and dementia are potentially modifiable. Early detection of reversible arterial injury may improve dementia risk stratification and provide an opportunity for treatment monitoring. We hypothesized that carotid ultrasound grayscale-median (GSM), a novel imaging biomarker of early arterial injury, would predict incident all-cause dementia in the Multi-Ethnic Study of Atherosclerosis (MESA).Methods:The MESA enrolled adults aged 45-84 years old who were free of atherosclerotic cardiovascular disease at baseline. Common carotid artery GSM (grayscale units) was measured at baseline. Incident all-cause dementia events were identified by hospital and death records. Adjusted Cox proportional hazards models with natural cubic splines allowing for non-linear effects investigated the associations of baseline GSM and incident all-cause dementia.Results:The 1,788 participants were a mean (standard deviation) 63.1 (10.3) years old (53% female). Over a median of 13.7 years, 157 all-cause dementia events occurred. Lower (worse) carotid GSM independently predicted incident all-cause dementia (Hazard Ratio [HR] 1st to 3rd tertile, 1.39 [95% Confidence Intervals, 1.08-1.80], p =0.04). In models adjusting additionally for carotid IMT there was no attenuation of the association of GSM and incident all-cause dementia (HR 1.63 [95% CI 1.13-2.35], p=0.033) (Figure 1).Conclusions:Lower GSM predicts incident all-cause dementia independent of carotid intima-media thickness, suggesting it may serve as an early marker of dementia risk.
Abstract 4144560: Phase 2 Open-label, Single-arm, Multi-center Clinical Trial to Evaluate the Efficacy and Safety of Camostat Mesylate in Patients with Protein-losing Enteropathy after Fontan Operation-Preliminary Outcome
Circulation, Volume 150, Issue Suppl_1, Page A4144560-A4144560, November 12, 2024. Introduction:Protein-losing enteropathy (PLE) is a multifaceted condition that profoundly affects the systemic health and quality of life of Fontan patients. Despite medical progress, the treatment of PLE remains a significant challenge. This study investigates the efficacy and safety of Camostat Mesylate for managing PLE patients who have undergone the Fontan operation.Hypothesis:We hypothesize that Camostat Mesylate will enhance the gut environment, resulting in increase of serum albumin levels and decrease of stool alpha-1 antitrypsin levels in PLE patients following Fontan operation.Methods:This phase 2, multicenter, open-label, single-arm trial included patients over 4 years old diagnosed with PLE following Fontan operation. Camostat Mesylate was added to conventional treatments, with follow-up assessments at 1, 3, and 6 months, and a final evaluation one month after discontinuation. Efficacy was measured by changes in serum albumin, stool alpha-1 antitrypsin levels, and PLE symptoms such as diarrhea, edema, weight changes, and ascites.Results:Nineteen patients were enrolled in the study, of whom fifteen patients completed follow-up as per protocol. The median age was 15 years (interquartile range, 12.0-21.3). The median time between the Fontan operation and PLE diagnosis was 2.4 years. Serum albumin levels increased from 2.5 to 2.6 g/dL (p=0.504), and stool alpha-1 antitrypsin levels decreased significantly from 280.0 to 172.1 mg/dL (p=0.033). Notably, patients with diarrhea at baseline showed substantial improvement in both parameters, with increased serum albumin levels from 1.8 to 2.2 g/dL and decreased stool alpha-1 antitrypsin levels from 220.3 to 80.2 mg/dL. No serious adverse events were reported during study period.Conclusions:Camostat Mesylate demonstrated safety and efficacy, reducing stool alpha-1 antitrypsin in PLE patients after Fontan operation, especially those with diarrhea at baseline. Therefore, Camostat Mesylate could be considered as an additional treatment option for patients with PLE following Fontan operation.Key words:Camostat mesylate; protein-losing enteropathy; Fontan operationSource of Funding:This research was funded by SNUH Lee Kun-hee Child Cancer&Rare Disease Project, Republic of Korea.
Abstract 4143265: Unveiling Gender Disparities in Chagas Disease patients with cardiac involvement: Insights from the NIS Database
Circulation, Volume 150, Issue Suppl_1, Page A4143265-A4143265, November 12, 2024. Background:Chagas disease (CD) is caused by a protozoan named Trypanosoma cruzi, in its chronic stage it may present with organ involvement, including the heart. Previous studies suggest that being a male is associated with increased mortality in CD. Understanding gender disparities associated with this condition is imperative for better patient management.Hypothesis:Gender has an impact on the outcome of CD with cardiac involvement.Aim:To investigate if gender has an impact on the clinical outcomes of CD with cardiac involvement.Methods:We examined the National Inpatient Sample data from 2016-2020, and conducted a retrospective descriptive study. We included all patients 18 years and older, male and female, diagnosed with CD with cardiac involvement. We excluded patients who were younger than 18 years of age. Baseline socio-demographic characteristics, comorbidities, and outcomes of the two groups were described. Hypothesis testing for categorical variables was performed using Chi-Square. Continuous variables were tested with a Student t-test. Statistical significance was defined as a two-tailed p-value of
Abstract 4139196: Long-term effectiveness and safety of mavacamten in a real-world, multi-center, global study: Preliminary results of COLLIGO-HCM from a diverse cohort in the United States
Circulation, Volume 150, Issue Suppl_1, Page A4139196-A4139196, November 12, 2024. Introduction:The mavaCamten ObservationaL evIdence Global cOnsortium in hypertrophic cardiomyopathy (COLLIGO-HCM; ClinicalTrials.gov ID NCT06372457) is a multinational, multicenter observational research initiative aiming to describe the real-world outcomes of mavacamten for the treatment of obstructive HCM.Aims:Describe the real-world effectiveness and safety of mavacamten, measured by echo measurements and NYHA class.Methods:This retrospective study used data from medical records from two participating HCM centers in the US. Patient-level data was extracted to assess the effectiveness and safety of mavacamten post-treatment initiation through 60 weeks. Patient characteristics and outcomes were described, including echocardiogram measurements, New York Heart Association (NYHA) functional class, and safety.Results:A total of 93 patients were treated with mavacamten (mean age 60.6 ± 13.9 years, 23.7% black, 57.0% female, and 77.4% NYHA class III at baseline) with a mean follow-up of 37.0 ± 28.1 weeks (Table). From baseline to week 60, 3 (3.2%) patients experienced temporary treatment discontinuation, and 3 (3.2%) discontinued mavacamten due to left ventricular ejection fraction (LVEF)
Abstract 4145056: A Comparison of Outcomes in Heart Failure Patients with and without Iron Deficiency Anemia: A National Database Analysis
Circulation, Volume 150, Issue Suppl_1, Page A4145056-A4145056, November 12, 2024. Introduction:Iron deficiency anemia (IDA) affects millions of people with heart failure (HF) and is of a higher proportion in patients admitted for HF than those seen as an outpatient. The cause of IDA in patients with HF is postulated to be related to the chronic inflammatory process that occurs resulting in decreased erythropoiesis. This could also be a side effect of the extensive treatment. The fate of patients admitted for exacerbation of heart failure, especially those with IDA could be fatal. This study uses the NIS HCUP database to assess the outcome of patients admitted from 2016 to 2019 with heart failure and co-existing iron deficiency anemia.Research question/ hypothesis:Patients with HF and co-existing IDA have worse outcomes than those without.Method:We used the NIS HCUP 2016 to 2019 database for the analysis. The primary outcome was inpatient mortality. Secondary outcomes such as mean length of hospitalization (LOS), mean total hospital charges (THC) adjusted for inflation and proportion of complications were computed. Data was analyzed using regression models adjusted for significant, confounding, sociodemographic and comorbid conditions.Discussion/ Results::The total population of hospitalizations for HF from 2016 to 2019 was 1270784 with 6.9% having IDA. A higher proportion of hospitalizations with IDA were women. The mortality from the HF admission was 39350 patients. IDA was associated with lower adjusted odds of inpatient mortality (2.5 vs 3.2%, aOR: 0.75, 95% confidence interval (CI) of 0.68-0.84. However, patients with IDA had significantly longer mean LOS and higher THC compared to patients without IDA. Patients with IDA also had increased adjusted odds or requiring pressors, developing acute kidney failure and respiratory failure.Conclusion::Although IDA did not appear to impact mortality in patients with HF, it was associated with higher inpatient complications and higher healthcare cost utilization. Researchers postulate that limitation of different codes being used when data is recorded could have contributed to the unimpacted mortality. Further studies are needed to decipher other factors. Addressing comorbid IDA in the outpatient setting may significantly decrease the cost associated with hospitalization for HF by decreasing the length of hospitalization and the hospital charges associated with those hospitalizations.
Abstract 4143977: Cardiovascular Toxicities in Chimeric Antigen Receptor Therapy in Relapsed and Refractory Multiple Myeloma and Lymphoma using FAERS database.
Circulation, Volume 150, Issue Suppl_1, Page A4143977-A4143977, November 12, 2024. Introduction:Chimeric Antigen Receptor T-cell therapy (CAR-T) has revolutionized the treatment of relapsed refractory multiple myeloma (RRMM) and lymphoma over the past decade. Our objective is to examine the incidence, patterns, and outcomes of cardiac events in patients with RRMM and lymphoma who are receiving CAR-T therapy, utilizing the FDA Adverse Event Reporting System (FAERS) database.Methods:We employed the FDA Adverse Event Reporting System (FAERS) database and the Medical Dictionary for Regulatory Activities (MEDRA) to conduct a retrospective post-marketing pharmacovigilance inquiry. We analyzed the incidence of cardiac events associated with six CAR-T products, namely Idecabtagene vicleucel, Cilitacabtagene autoleucel, Axicabtagene ciloleucel, Tisagenlecleucel, Lisocabtagene maraleucel, and Brexucabtagene autoleucel, since their FDA approval (accessed 05/01/2024). We assessed the cardiotoxicities such as coronary artery disease (CAD), myocardial infarction (MI), arrhythmia, heart failure, and hypotension.Results:A total of 12,949 adverse events, including Axicabtagene ciloleucel (n=6222, 48%), Brexucabtagene autoleucel (n=1127, 8.7%), Tisagenlecleucel (n=3290, 25.4%), Lisocabtagene maraleucel (n=463, 3.5%), Idecabtagene vicleucel (n=722, 5.5%), and Cilitacabtagene autoleucel (n=1125, 8.6%). Of those, 675 cases (5.2% of the total) that were related to cardiac events, regardless of their severity. The cardiotoxicity incidence was highest in Brexucabtagene autoleucel (n=85,7.5%), followed by Idecabtagene vicleucel (n=50,6.9%), Tisagenlecleucel (n=208,6.3%), Axicabtagene ciloleucel (n=278,4.5%), Lisocabtagene maraleucel (n=17,3.6%), and Ciltacabtagene autoleucel (n=37,3.2%).Cytokine release syndrome (CRS) is linked to nearly 440 cardiac events,accounting for 65% of all cardiac events.The most prevalent cardiotoxic event was Atrial Fibrillation (122), followed by the development of heart failure (113), Ventricular arrhythmia (108), hypotension (87), and Brady arrhythmia (41).The recipients of Brexucabtagene autoleucel had the highest mortality rate (n = 26,2.3%), followed by those receiving Tisagenlecleucel (n = 71,2.1%) and Lisocabtagene maraleucel (n = 10,2.1%).Conclusion:The cardiotoxic properties of CAR-T therapy can lead to fatal adverse events. Improving outcomes and preventing mortality in these populations can be achieved through timely monitoring.
Abstract 4146723: Integrating Multi-Omics, Phenotypic, and Social Determinants for Stroke Prediction in Atrial Fibrillation: Advancing Precision Health Using Machine Learning
Circulation, Volume 150, Issue Suppl_1, Page A4146723-A4146723, November 12, 2024. Introduction:Atrial fibrillation (AF) is linked to an elevated risk of ischemic stroke (IS) and mortality. However, the performance of existing clinical scoring systems in assessing these outcomes is at best moderate. The blood proteome serves as a vital indicator of biological processes related to complex disorders. Consequently, there exists an opportunity to enhance the predictive accuracy of such risk scores by incorporating blood proteomic data.Purpose:In this study, we aim to evaluate the combined influence of genomics, proteomics, biomarkers, phenotypic, and social determinants of health (SDOH) on AF outcomes to better understand a precision health framework in managing AF.Methods:We analyzed patients with AF in the UK Biobank cohort who underwent proteomics measurements using the Olink Proximity Extension Assay. The primary endpoint was the incidence of IS.We assessed the intersection of multi-omics,comorbidities,SDOH and traditional CHA2DS2-VASc score to identify the most important factors associated with IS.We employed multi-step machine learning algorithms to evaluate 3,083 features, including Step1,which involved separate models for each feature type,followed by Step 2,where a combined model was used to assess the complex relationship between these features.The area under the curve (AUC) was used to compare the discriminative ability of the model with the addition of each feature group for predicting IS.Grid search and 10-fold cross-validation were performed to identify the best hyperparameters,and we calculated the mean AUC for the final models.SHAP values were reported for the top 30 features in the final XGBoost model (Figure1).Results:Among 4,842 patients with AF(mean age 67.2±9.5 years,61.8% female),5.2% experienced an IS within 9.9±7.5 years after AF diagnosis.The mean CHA2DS2-VASc score was 2.3±1.4, with 60.14% on anticoagulation therapy.The AUC for the CHA2DS2-VASc score at baseline was 0.493.Adding SDOH, polygenic scores, phenotypic data, proteomics, and biomarkers improved the model’s discriminative ability (Figure 1.A), with a combined model AUC of 0.619 (95% CI: 0.592-0.645)(Figure 1.B).The top 30 features in the final model, primarily proteins, are shown in Figure 1C.Conclusion:A small number of plasma proteins can substantially enhance risk prediction of IS in the setting of AF. Further validation could enable a single-source,personalized assessment of stroke risk in patients with AF as a gateway to personalized risk reduction therapy.
Abstract 4124307: Outcome of Obesity in Atrial Fibrillation – Insights from The National Inpatient Sample Database
Circulation, Volume 150, Issue Suppl_1, Page A4124307-A4124307, November 12, 2024. Background:Obesity is considered a significant risk factor for numerous cardiovascular conditions due to its effects on cardiac structure and function. The prevalence of atrial fibrillation (AF) is elevated among patients with obesity due to the dysregulation of several mechanisms. Weight loss has been shown to reverse cardiac remodeling, leading to a lower recurrence of AF despite the better prognosis in obese patients described as the obesity paradox.Methods:We utilized the National Inpatient Sample 2016-2019 to extract patients ≥18 years of age admitted with AF as the primary diagnosis based on ICD 10 codes. We performed univariate and multivariate regression analysis for known coronary risk factors. We divided patients based on their body mass index (BMI), and our primary outcomes were determining the odds of electrical cardioversion (ECV) and cardiac ablation (CA) due to AF.Results:The analysis included 1,625,809 weighted patients. Patients include underweight (6.66%), normal BMI (4.03), overweight (6.51%), obesity class I (20.65%), obesity class II (21.45%), and obesity class III (40.7).After multivariate regression analysis, patients with obesity class I, II, or III had higher odds of ECV, irrespectively of coronary risk factors (OR 1.3, 95% CI 1.25-1.37, OR 1.3, 95% CI 1.32-1.43, OR 1.3, 95% CI1.29-1.38, respectively, with statistically significant P values). However, underweight or normal BMI patients had fewer odds of ECV (OR 0.5 95%CI 0.49-0.61 and OR 0.6 95%CI 0.58-0.74, respectively, with P values
Abstract 4143692: Racial Disparities in Age-adjusted Sudden Cardiac Death Rates in the United States: Insights from CDC-WONDER Database, 1999-2020
Circulation, Volume 150, Issue Suppl_1, Page A4143692-A4143692, November 12, 2024. Hypothesis:Small prospective and dataset-based studies predicted the rates of sudden cardiac death (SCD) are higher in the African American (AA) population as compared to White Americans (WA). However, there is a lack of long-term data over two decades lookingfor racial differences in SCD.Aim:Our study aims to analyze and quantify the racial differences in age-adjusted mortality rates(AAMR) related to SCDs between AA and WA to further explore potential contributing factors, such as socioeconomic status, sex, and varied comorbidity burdens, to these differences.Methods:We analyzed the Centers for Disease Control and Prevention (CDC) Wide-ranging Online Data for Epidemiologic Research (WONDER) database, containing death certificate records for various causes of mortality in the US from 1999 to 2020. We searched the CDC WONDER database for patients, 18-45 years old whose cause of death was SCD corresponding to ICD-10 code; I46.1. We searched for AAMR and stratified patients based on race and gender on a total population of 48668 (41975 WA; 6693 AA). Temporal trends were analyzed by fitting log-linear regression models using the Joinpoint Regression Program.Results:We calculated annual percent change (APC) with 95% confidence intervals (CIs) in AAMR for the line segments linking joint points. The AAMR for SCDs in AA males ranged from 2.1% in 2000 to 0.9% in 2020 with an APC of 0.68 between 1999 and 2009, -26.72 between 2009 and 2012, and 4.34 between 2012 and 2020 suggest that the rate peaked between 2008 and 2010, followed by a significant decline in the following years. WA males had consistently lower rates compared to AA males. The AAMR for WA males peaked at 1.5% in 2000 followed by a stepwise decline until it reached a rate less than 0.9% in 2020, with APCs -1.32 between 1999 and 2009, -19.58 between 2009 and 2012. [Figure A]. AA females had APCs of 2.01, -31.88, and 1.73 while WA females had APCs of -2.32, -21.38, and 0.43 between 1999 and 2009, 2009 and 2012, and 2012 and 2020, respectively [Figure B]. Rates in AA females had a similar progression to that in AA males [Figure C].Conclusion:Racial disparities in SCDs related AAMR in the US suggest the role of a complex interplay between healthcare delivery, underlying pathological processes, and race. AA demonstrated higher age-adjusted SCD rates than WA. These findings should be used to guide policymaking and address areas of unmet need in providing racially equitable healthcare for all patients.
Abstract 4147547: Sex-Based Disparities in Paroxysmal Atrial Fibrillation Outcomes: An Analysis of the National Readmission Database
Circulation, Volume 150, Issue Suppl_1, Page A4147547-A4147547, November 12, 2024. Background:Paroxysmal atrial fibrillation (PAF) is an intermittent irregular arrhythmia that terminates within seven days. Prior studies have shown that females with atrial fibrillation are at increased risk of mortality and readmissions compared to men. Given the dramatic rise in PAF diagnoses over the past several years, the impact of sex on clinical outcomes in this patient population requires further analysis. This study aims to investigate sex-based disparities in clinical outcomes over recent years for patients with PAF.Methods:In this large scale, retrospective cohort study, patients who were admitted with PAF were analyzed from 2016 to 2020 using the National Readmissions Database. The study population was divided into male and female groups. Diagnoses were classified according to the International Classification of Diseases Tenth (ICD-10) Revision codes. The primary outcome was 30-day readmissions. Secondary outcomes included inpatient mortality and length of stay.Results:During the study period, a total of 548,617 patients with PAF meeting inclusion criteria were admitted. Of this population, 55.3% were female (n = 303,412) and 44.7% (n =245,205) were male. The mean age was 73.7 ± 11.9 years for females and 65.7± 13.6 years for males. After adjusting for baseline characteristics, female sex was associated with a higher 30-day readmission rate (HR: 1.06, CI: 1.03-1.09, p < 0.001). Multivariate regression analysis for inpatient mortality and length of stay was higher for females than males (p < 0.01 for both).Conclusion:Female patients experienced worse overall outcomes compared to male patients with higher readmission rates, inpatient mortality, and longer length of stay. These data suggest that targeted intervention for females may be required to improve these outcomes.
