Abstract 9455: Sex Differences in Atrial Fibrillation Ablation Outcomes From the National Inpatient Sample Database 2016-2019

Circulation, Volume 146, Issue Suppl_1, Page A9455-A9455, November 8, 2022. Background:Research has shown mixed results when comparing in-hospital complications following atrial fibrillation ablation in women compared to men.Objectives:To better quantify sex differences and in-hospital outcomes in atrial fibrillation ablation procedures and identify factors associated with poorer outcomes.Methods:We queried the NIS database from 2016-2019 for hospitalizations with a primary diagnosis of atrial fibrillation ablation and excluded patients with any other arrhythmias, ICD/pacemaker placement. We assessed demographics, in-hospital mortality, and complications of women compared to men. Outcomes were adjusted for potential confounders using multivariable logistic regression analysis (Figure 1).Results:Admissions for atrial fibrillation were more common in females than males (849,050 versus 815,665; p

Abstract 14473: The Impact of Dietary Patterns on Cardiovascular Death Comparing Populations of United States and Great Britain: An Analysis of the Global Burden of Disease Study 2019

Circulation, Volume 146, Issue Suppl_1, Page A14473-A14473, November 8, 2022. Introduction:Dietary risk factors contribute to cardiovascular mortality. To the best of our knowledge, there are no studies comparing two first world countries with respect to cardiovascular deaths (CVD) and the impact of dietary risk factors. We sought to compare these parameters in Great Britain (GBR) and the United States of America (USA)Methods:A total of 33,041,416 patients with dietary risk factors and CVD from GBR and USA was obtained from the Global Burden of Disease Study between 1990 and 2016.The 30-year mean CVD was compared for all risk factors with the Welch Two sample t-test. Trends of CVD proportions of 30-years is as shown (Fig 1 and 2).Results:30-year mean cardiovascular death for all variables between GBR and USA was statistically significant (p< 0.05) with the exception of diet low in whole grains. Cardiovascular death with risk factors of diet low in PUFA, fruits, vegetable, nuts and seeds were measures where GBR had a higher 30-year mean CVD than the USA. Remaining factors contributed to higher CVD proportion in USA.Conclusions:A higher proportion of CVD was seen in the USA with dietary risk factors including low PUFA, processed meat, sweetened beverages, low legumes, high sodium and high trans-fatty acids when compared to GBR. Our study proves that there exists significant disparity in CVD proportions between two first world countries despite similar dietary risk factors.

Abstract 12142: Cardiovascular Associations of Chimeric Antigen Receptor T-cell Therapy: A Retrospective Cohort Study From National Inpatient Sample 2016-2019

Circulation, Volume 146, Issue Suppl_1, Page A12142-A12142, November 8, 2022. Introduction:After FDA approval in 2017, chimeric antigen receptor (CAR) T-cell therapy gained high popularity in various hematological malignancies.Hypothesis:There are no sex-based differences in in-hospital mortality and length of stay after CAR T-cell therapy.Methods andResults:From 2018 to 2019, using national inpatient sample, among a total of 14,189,303 hospitalizations (unweighted sample) 704 (0.01%) CAR T-cell therapy were performed, 306 in 2018 and 408 in 2019. Among the CAR T-cell therapy performed, 58.4% (n = 417) were males, 2.9% (n=21) had pulmonary edema, 0.6% (n=6) had acute decompensated heart failure, 3.08% (n=22) had supraventricular tachycardia, 3.36% (n=24) had ventricular tachycardia, 1.94% (n=14) had pericardial effusion (including chronic pericarditis or tamponade), 0.14% (n=1) had acute pericarditis, 0.14% (n=1) had non ST-segment elevation myocardial infarction, 3.64% (n=26) required pressors, 8.68% (n=64) had atrial fibrillation, 3.64% (n=26) had disseminated intravascular coagulation, 4.76% (n=34) required mechanical ventilation. 3.92% (n=28) died in the hospital and mean length of stay (LOS) was 20.5 days. The mean age for CAR T-cell therapy was 54 ± 18 years. Among CAR T cell therapy population, compared to males, females were similar in age (mean age: 54.6 vs. 54 years; p=0.606), had lower incidence of atrial fibrillation (4.38% vs 11.75%, p

Abstract 10072: Sex Disparities in Cardiovascular Events Among Sarcoidosis Patients: Insights From 2019 National Inpatient Sample

Circulation, Volume 146, Issue Suppl_1, Page A10072-A10072, November 8, 2022. Introduction:Sarcoidosis involves many organs in the body, including the heart, thus triggering various cardiovascular dysrhythmias and complications. We sought to analyze the cardiovascular events seen in these patients.Methods:The 2019 National Inpatient Sample (NIS) is one of the most extensive inpatient databases in the United States. It was used to explore and identify patients diagnosed with sarcoidosis and a valid entry for the variable “Sex”. Hospitalizations associated with several cardiac events were also examined (reported as cases per 100 males or females), and their occurrences were compared between males and females. Multiple logistic regression adjusted to non-cardiac characteristics allowed us to estimate the adjusted odds ratio (aOR) of the cardiovascular events in females relative to males.Results:We found 84,640 cases of sarcoidosis (61.5% females, and 38.5% males). Females were less likely to present with supraventricular tachycardia (2.1 vs. 2.4, aOR 0.804, p

Abstract 15756: The Beneficial Impact of Primary Care Providers’ Supply on the Cardiovascular Mortality Rates in the United States: A Nationwide Population Analysis 2011-2019

Circulation, Volume 146, Issue Suppl_1, Page A15756-A15756, November 8, 2022. Introduction:United States is facing an increasing shortage of primary care physicians (PCP) and health care demands. However, data on the relationship between PCP availability and burden of cardiovascular mortality (CVM) and related disparities, is limited.Hypothesis:Herein, we evaluate the nationwide impact of county PCP levels on CVM in overall and within disparate populations stratified by age, sex, and race/ethnic subgroups.Methods:PCP is calculated as the ratio of PCPs to the population, using data from National Center for Health statistics. Age-adjusted CVM rates (ACVM) between 2011 to 2019, were obtained using CDC database. Behavioral Risk Factor Surveillance was utilized to acquire county characteristics and confounders. Poisson linear mixed model was employed.Results:Of 3143 U.S. counties, 2900 counties (62% white; 51% female; 14% aged ≥65) had data available on ACVM and PCP.In a multivariate model adjusted for demographics, CV risk, socioeconomic, and environmental factors, higher PCP levels significantly associated with lower ACVM (Standardized IRR: 0.979; 95% CI: 0.972 to 0.986), which translates to 4.8 fewer CV deaths each year (AYD). This effect was relatively higher in middle-aged [45-64] (IRR: 0.967) versus elderly [≥65] (IRR: 0.980), males (IRR: 0.981) versus females (IRR: 0.972), and within Whites (IRR: 0.976). Notably, the relative impact of PCP was greatest in [45-64] Whites (IRR: 0.963), while the absolute impact was highest amongst ≥65 males with 36 fewer CV deaths each year. (Figure).Conclusions:Higher PCP supply is robustly associated with lower ACVM, and that beneficial effect is most evident amongst both age and sex subgroups as well as non-Hispanic whites. Moreover, this association is significantly independent of potential confounders that have a plausible association with CVM. Therefore, population-level strategies to promote primary care access, are imperative for reducing the burden of CVM and promoting health equity.

Abstract 12160: Sex Differences in Outcomes of Percutaneous Coronary Intervention in Octogenarians: A Retrospective Cohort Study From National Inpatient Sample 2016-2019

Circulation, Volume 146, Issue Suppl_1, Page A12160-A12160, November 8, 2022. Introduction:The role of sex-based differences in the outcomes after principal percutaneous coronary intervention (PCI) in octogenarians is not well studied.Hypothesis:There are no differences in outcomes of PCI in octogenarians based on sex.Methods and Results:From 2016 to 2019, 37,147 hospitalizations (unweighted sample) for principal PCI procedures were identified. Among the principal PCI procedures performed, 44.9% (n = 16,660) were performed in females, and 55.2% (n = 20,487) in males (p < 0.001), 82.4% in Whites, 5.4% in Blacks, 6.4% in Hispanics, and 2.6% in Asians. 20,986 (56.5%) principal PCI hospitalizations had a Charlson comorbidity index (CCI) of three or higher. The mean age for Octogenarians was 83.6 ± 2.7 years. Compared to males, the females were slightly older (mean age: 83.8 vs. 83.5; p < 0.001), had higher prevalence of diabetes mellitus (20.5% vs 18%, p

Abstract 11761: Increasing Trend in All-Cause Mortality Among Elderly Black Patients Hospitalized With Acute Myocardial Infarction With Prior Coronary Artery Bypass Grafting – A Nationwide Inpatient Analysis 2016-2019

Circulation, Volume 146, Issue Suppl_1, Page A11761-A11761, November 8, 2022. Background:Acute myocardial infarction (AMI) in elderly patients who have previously undergone coronary artery bypass grafting (CABG) poses a diagnostic and therapeutic complexity. There is limited data on cardiovascular and mortality outcomes for this population.Methods:Using the National Inpatient Sample (NIS) from 2016-2019, we identified patients over 65 years with a prior CABG presenting with AMI, excluding those with a history of percutaneous coronary intervention. After assessing baseline characteristics, we analyzed trends in cardiovascular disease (CVD) risk and all-cause in hospital mortality (ACM) while stratifying for gender and race. Pearson’s chi-squared test was utilized to compare the CVD variables.Results:There were 266,365 hospitalizations included in the study with a median age of 77 years. They were predominantly males(69.5%), of Caucasian origin (81.7%), Medicare enrollees (91.4%) and were admitted in urban teaching hospitals (67.2%) located in the South of the US (39.5%) as non-elective cases (93.8%). Between 2016-19, Hyperlipidemia (HLD), smoking(Sm), and obesity(Ob) showed an increasing trend in males (2.8%, 1.3%, and 2% respectively) and females (2.1%, 2.4%, and 2% respectively), whereas hypertension (HTN) decreased by 4.5% in males and 6.3% in females.The length of stay remained constant at 4 days and the average cost of stay was 58963.5 USD. HTN among all races decreased from 2016 to 2019 except for Native Americans. HLD and obesity exhibited an upward trend among all races. Hispanics and Asians/Pacific Islanders(PI) had a consistent downtrend in mortality rates, with Native Americans showing the biggest drop in mortality rate (6.9%). All-cause mortality decreased from 2016 to 2019 by 1.4% except for Blacks which has increased by 2.6%, overtaking Asian/PI. All p

Abstract 14768: Contemporary Hospitalization and Thirty-Day Readmission Rates of Unstable Angina in the United States: Insights From Nationwide Readmissions Database 2016-2019

Circulation, Volume 146, Issue Suppl_1, Page A14768-A14768, November 8, 2022. Introduction:There are limited data on the contemporary hospitalization rate and 30-day readmission characteristics of unstable angina (UA).Methods:Using Nationwide Readmissions Database from 2016 to 2019, we identified UA hospitalizations based on ICD-10-CM codes and analyzed the rate, trend, timing, causes, and costs of 30-day readmissions after UA in the United States. Multivariable regression analysis was conducted to determine the predictors of 30-day readmission.Results:A total of 498,008 patients were hospitalized with UA, resulting in the in-hospital mortality of 0.4%. During the study period, a significant decrease in the temporal trend of UA hospitalization rate was observed (Figure 1). Among 458,823 patients who were discharged alive, 11.4% were readmitted within 30 days with a median time to readmission of 9 days. There was a significant reduction in the temporal trend of 30-day readmission rate (Figure 2). The most common cause of readmission and procedure during the readmission were recurrent UA and left heart catheterization, respectively. While cardiovascular comorbidities, including congestive heart failure and atrial fibrillation, were associated with an increased likelihood of 30-day readmission, the ischemic evaluation performed during index hospitalization was associated with decreased odds of readmission (Table). The mortality during the readmission was 2%. The cumulative costs of hospitalization were $30,729 vs. $14,998 for UA patients with and without readmission, respectively.Conclusions:The index hospitalization and early readmission rates of UA have decreased over time. About 1/10 of UA patients were readmitted within 30 days of discharge, primarily due to recurrent UA. The early readmission may be reduced by a timely ischemic evaluation following UA.

Abstract 15771: Disparities in Cardiovascular Death Proportions Based on Age-Standardized Gross Domestic Product Classification of Countries: Global Burden of Disease 2019

Circulation, Volume 146, Issue Suppl_1, Page A15771-A15771, November 8, 2022. Introduction:Socioeconomic status impact cardiovascular disease outcomes. There is a paucity of data comparing age-standardized Gross Domestic Product (aGDP) and age-based proportion of CVD deaths (pCVD).Methods:We analyzed World Development Indicators and Global Burden of Disease 2019 study data. aGDP, CVD, total all-cause deaths, and their distribution amongst ‘High Income’ (HI), ‘Upper-Middle Income’ (UM), ‘Low-Middle Income’ (LM), and ‘Low Income’ (LI) countries from 2010-2019 was queried. ANOVA with Kruskal-Wallis Test followed by post-hoc analysis with Tukey test was conducted to examine the differences in pCVD among different income category countries based on age groups (Table 1b).Results:A total of 169,825,716 CVD (35.4%) were noted out of 478,797,297 total all-cause deaths globally. There was a significant difference comparing all income classes (p < 0.001) in age groups except between UM and LI in the age groups 15-49 and 50-69 (p = 0.885 and 0.261 respectively). In the age group 5-14, pCVD was higher in HI, UM, LM and LI classes (3.74%, 3.41%, 2.48 and 1.96%, p < 0.01). In age groups 15-49, pCVD was higher in UM and LM (17.70%, 17.50%), and lower pCVD in HI and LI classes (15.07% and 8.52%). At the age > 70, higher pCVD was seen in UM, followed by LM, LI, and HI (50.05%, 40.93%, 36.74% and 35.78% respectively, p < 0.001). The highest overall pCVD was observed in the UM class.Conclusions:Our study shows a statistically significant difference in pCVD between the World Bank classes of countries based on age groups. There is higher pCVD in HI, both-middle-income, and UM classes in the age groups 5-14,15-69, and >70 respectively, with overall pCVD being higher in UM class.
