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.

Circulation, Volume 150, Issue Suppl_1, Page A4140013-A4140013, November 12, 2024. Background:Prior research has noted disparities in sleep duration among demographic groups and those with cardiometabolic disorders. However, these are mostly based on self-reported data. The NIH All of Us Fitbit database offers a new method for objective and reliable sleep assessment.Goals:The study aimed to objectively assess sleep duration using the All of Us Fitbit database across various demographic variables and cardiometabolic disorders.Methods:All of Us participants with at least one year of Fitbit data were identified. Fitbit’s “minutes asleep” parameter was extracted daily over the first year of Fitbit use and averaged. The average total minutes asleep (TMA) was compared across self-reported age, sex and race groups. For those individuals who also shared their electronic health record (EHR) data, TMA was compared between those with and without hypertension, diabetes, and sleep apnea. T-test and ANOVA were used for comparisons.Results:The first year of Fitbit data for 13,039 participants (51 [16]* years, 69% female, 82% White) was analyzed, with sleep information available for 330 [104] days (90% complete data). TMA decreased with age, with the 18-44, 45-64, and 65+ groups averaging 366 [64], 348 [72], and 339 [85] minutes respectively (p

Circulation, Volume 150, Issue Suppl_1, Page A4140245-A4140245, November 12, 2024. INTRODUCTION:Atrial fibrillation (AF), often diagnosed in the Emergency Department (ED), increases the risk of stroke by 64% but can be mitigated by guideline-directed oral anticoagulant (OAC) treatment.RESEARCH QUESTION:Does clinician education of an AF clinical decision support (CDS) tool increase OAC prescription rates for patients with new-onset AF or paroxysmal AF (pAF)?GOALS:To increase guideline recommended care practice of OAC prescribing for appropriate candidates in the ED.Methods:This multi-center, multi-phase, stepped-wedge cluster-randomized clinical trial includes a retrospective phase (Phase 0) and implementation of an external browser link to the CDS in the EHR (Phase 1) which included patient-specific stroke and bleeding risk stratification scores with recommendation for OAC based on professional society guidelines, along with targeted provider education on how to use the resource. Data was collected from ED visits of patients aged > 18 with a primary AF/pAF diagnosis from Jan 1, 2020–May 25, 2024. The three sites, one academic and two community hospitals, implemented Phase 1 in January ‘22, April ‘22, and April ‘23. Eligibility for OAC treatment was based on clinical judgment weighing the benefit of stroke prevention against the risk of bleeding. A logistic GEE model assessed the intervention’s impact on OAC prescribing and treated ED providers as a random effect to account for clustering. The model included the CDS intervention and covariates for site, cardiology consultation, guideline citation, and patient factors such as sex, race, ethnicity, and age.Results:Of 4397 patients analyzed, 655 met inclusion criteria, among which 296 (45.19%, median age 68) were prescribed OAC, 175 in Phase 0, and 121 in Phase 1. The odds ratio estimates and their corresponding 95% confidence intervals are as follows: CDS intervention 1.75 [1.20, 2.54], sex female vs male 2.31 [1.57, 3.38], age 0.27 [0.12, 0.61], site 0.55 [0.29, 1.04] and 0.45 [0.25, 0.83] for each community site vs academic, cardiology consultation 4.56 [2.80, 7.42], and guideline citation 2.23 [1.44, 3.43]. Race and ethnicity did not show significant associations.CONCLUSION(S):We demonstrated that clinician education and limited CDS tool integration into the EHR are linked to an almost two-fold increase in OAC prescribing for suitable AF/pAF patients. Future studies should evaluate the influence of further CDS integration on OAC prescribing, long-term adherence, patient outcomes.

Circulation, Volume 150, Issue Suppl_1, Page A4146291-A4146291, November 12, 2024. Background:Circulatory diseases represent the primary cause of mortality in the US. Comprehending trends and potential disparities in the prevalence of circulatory conditions, such as angina pectoris (AP), myocardial infarction (MI), hypertension (HTN), and coronary heart disease (CHD), is essential for forming public health strategies.Aim:To investigate trends in the prevalence of circulatory conditions, including AP, MI, HTN, and CHD among US adults from 2019 to 2022.Methods:Prevalence percentages for all available circulatory diseases from the Centers for Disease Control and Prevention’s National Health Interview Survey (NHIS) database were retrieved for patients aged >18 years from 2019 to 2022. Annual Percentage Changes (APCs) along with their respective 95% CIs were calculated using regression analysis with Join point. The data was stratified by year, gender, age, race, nativity, veteran status, social vulnerability, employment status, metropolitan statistical area (MSA) status and census region.Results:Between 2019 and 2022, HTN was steadily the most prevalent, staying relatively constant at 27.0% (95% CI: 26.4, 27.7) in 2019 and 27.2% (95% CI: 26.5, 27.8) in 2022. Males consistently had higher prevalence than females with significant increases noted from 2019 to 2022 (APC: 1.0234). Black or African American had the highest prevalence (34.4% in 2022). The South (30.1% in 2022) and the West (22.5% in 2022) had respectively the highest and lowest rates. The second highest prevalence was seen in CHD increasing from 4.6% (95% CI: 4.3, 4.9) in 2019 to 4.9 (95% CI: 4.7, 5.2) in 2020. Males consistently exhibited a higher prevalence than females, with both genders showing significant increases in recent years (Male APC: 3.1448) (Female APC: 2.0165). For MI, a slight decrease was noted from 3.1% (95% CI:2.9, 3.4) in 2019 to 3.0% (95% CI:2.7, 3.2) in 2022. White individuals exhibited the highest prevalence (3.3% in 2022). AP had the lowest overall prevalence staying relatively consistent (1.7% in 2019 and 1.6% in 2022) (Figure 1).Conclusion:Significant trends (Figure 2) in most common circulatory diseases have been identified. Targeted interventions are imperative, particularly for high-risk demographics such as males, older adults, veterans, and unemployed individuals.

Circulation, Volume 150, Issue Suppl_1, Page A4139238-A4139238, November 12, 2024. Intro:Myocarditis is an inflammatory cardiac condition that may progress to dilated (DCM) or arrhythmic (ACM) cardiomyopathy. Prior cohort studies indicate genetic factors significantly influence myocarditis susceptibility and outcomes; yet, this has not been studied at a population level, which holds potential for clinical risk prediction.Objective:To investigate DCM and ACM gene variant burden and clinical consequences by a multi-population approach encompassing diverse genetic ancestries.Methods:Individuals with exome sequencing (ES) in UKBB and AoU were included, and poor-quality samples excluded. Individuals with myocarditis were identified by ICD code and compared with myocarditis-neg population. Cardiomyopathy (CM) genes in ClinGen DCM- and ARVC-associated genes with at least moderate evidence of disease causality were included and filtered by our previously published variant pipeline and ClinVar 2* criteria for pathogenic/likely pathogenic (P/LP). Cardiac phenotype and CM variant burden were analyzed by chi-squared analysis.Results:200,580 individuals in UKBB and 230,013 in AoU had ES. 137 in UKBB and 284 in AoU had myocarditis. Myocarditis cohorts in both populations had increased phenotypic burden of CM, ventricular arrhythmia, and HF vs myocarditis-neg. Myocarditis-pos showed increased CM (16.8% vs 0.2%); VA (10.9% vs 0.9%) and HF (32.8% vs 3.1%) in UKBB (p

Circulation, Volume 150, Issue Suppl_1, Page A4147077-A4147077, November 12, 2024. Background:Tricuspid regurgitation (TR) worsens heart failure symptoms and perpetuates right ventricular failure (RVF). Given the limited efficacy of medicines and high risk of surgical mortality, percutaneous therapeutic options are gaining importance. The TRILUMINATE study reported an 86% reduction in TR severity and 4% mortality rate using Triclip G4 tricuspid transcatheter edge-to-edge repair (T-TEER) system with improvement in health status. Triclip subsequently gained FDA approval for TR on April 2, 2024.Objective:To evaluate reported device and patient related adverse events during early experience with Triclip system for T-TEER.Methods:The events reported for Triclip since it gained FDA approval were extracted from the FDA MAUDE database. Previously published reports, duplicates and events before FDA approval were excluded. Grades of TR at baseline and after T-TEER associated with single leaflet device attachment (SLDA) were compared using Wilcoxon rank sum test.Results:After excluding 14 reports, 45 were included, dating from 04/02/24 to 05/31/24. Of these, 31 (67.4%) featured patient complications, with SLDA being the most frequent (n=24, 53%).(Figure-1) Cause of SLDA was reported in 8 reports.(Figure-2) SLDA led to regression of TR to pre-procedure levels in 10 patients and Polymorphic VT in one patient. Other patient issues included damage to leaflets (n=7, 15.6%) which necessitated surgery in one case and prompted consideration of the same in another. There were 4 reports of clip entrapment in the chordae. Device-related issues included 3 cases of leaks in the steerable guide catheter affecting its ability to hold the column, knotting on the lock line, difficulties with positioning the second clip above the valve, clip reopening beyond the expected 5°, clip opening while locked but staying closed post-deployment, delays in clip delivery, and challengers in guiding catheter positioning. No acute deaths were reported in the MAUDE database within 2 months of device approval.Conclusion:Our research findings summarize the reported adverse events during the early period following FDA approval of Triclip G4 T-TEER system. This provides valuable insights into common failure modes and complications, offering guidance on their optimal utilization. Multiple adverse events can be noted soon after approval of the Triclip, underscoring the importance of good initial training and proctoring.

Circulation, Volume 150, Issue Suppl_1, Page A4144108-A4144108, November 12, 2024. Background:The CHA2DS2-VASc risk score is a clinical tool for stroke prediction. It is mainly used in patients with atrial fibrillation (AF) but is also applied to the non-AF population. We previously reported that artificial intelligence (AI)-enabled left atrial (LA) volumetry from coronary artery calcium (CAC) scans (AI-CAC) predicts AF as early as one year and outperformed CHARGE-AF and NT-proBNP. In this report, we compare AI-CAC LA volumetry to the CHA2DS2-VASc risk score and evaluate the incremental value of incorporating AI-CAC LA volume to CHA2DS2-VASc for incident stroke prediction in the non-AF population.Methods:We applied the AutoChamberTMLA volumetry component of AI-CAC to CAC scans of 5830 people without AF (52.2% women, age 61.7±10.2 years) enrolled in the Multi-Ethnic Study of Atherosclerosis (MESA) baseline (2000-2002). We used the 15-year outcomes data for incident stroke (ischemic and hemorrhagic) and assessed discrimination using the time-dependent area under the curve (AUC) between AI-CAC LA volume vs. CHA2DS2-VASc risk score. Notably, the CHA2DS2-VASc score in this non-AF population ranges from 0 to 5, whereas in the AF population it typically ranges from 0 to 9 points.Results:252 cases of stroke accrued over 15 years. The median and mean ± SD of CHA2DS2-VASc score at baseline were 1.0 and 1.58 ± 1.15, respectively. The cumulative incidence of stroke for the 95thpercentile of AI-CAC LA volume (n=291) vs. CHA2DS2-VASc 4 or 5 points (n=364) was 13.0% and 13.7%, respectively. AI-CAC LA volume significantly improved the AUC of CHA2DS2-VASc for stroke prediction at 2-year follow-up (0.76 for CHA2DS2-VASc vs. 0.81 for CHA2DS2-VASc plus LA volume, p=0.03), 5-year follow-up (0.73 vs. 0.77, p=0.01), 10-year follow-up (0.70 vs. 0.75, p

Circulation, Volume 150, Issue Suppl_1, Page A4146494-A4146494, November 12, 2024. Background:Distribution patterns for visceral (VAT), abdominal subcutaneous (ASAT), and gluteofemoral (GFAT) adipose tissue are strongly associated with cardiovascular disease. Circulating metabolites and proteins are dynamic indicators of biological processes and reflect metabolic health. It is not yet clear how these analytes are associated with adiposity distribution patterns.Aims:To determine the multi-omic profiles of adiposity distribution and their associated metabolomic and proteomic measurements.Methods:MRI-derived volumes of VAT, ASAT, and GFAT adjusted for BMI were available for 40,032 UK Biobank participants. Circulating metabolites and proteins were measured using the Nightingale Health NMR biomarker platform and Olink platform, respectively. We used linear regression models to assess the association between each analyte and VAT, ASAT, and GFAT. Models were adjusted for sex, age at MRI, MRI batch, and time between enrollment and MRI. Functional protein pathway enrichment was performed using the DAVID annotation tool.Results:Among 40,032 UK Biobank participants with adiposity volumes, 22,630 (56.5%) and 5023 (12.5%) had 168 metabolomic and 2910 proteomic measurements, respectively. In the metabolomic subset, the mean (SD) age was 55.7 (7.5) years, 10,992 (48.6%) were male, and all self-reported as white. In the proteomic subset, the mean (SD) age was 54.9 (7.8) years, 2417 (48.1%) were male, and all self-reported as white. Multi-variable linear regression revealed 39, 139, and 146 significant metabolite associations (P

Circulation, Volume 150, Issue Suppl_1, Page A4147545-A4147545, November 12, 2024. Introduction:Pulsed field ablation (PFA) is an adaptation of direct current ablation first used for catheter ablation in the 1980s. Expectations of a reduced risk profile led to the current resurgence in investment and interest in the technology as a potential alternative energy source for ablations to treat atrial fibrillation (AF). However, reports of adverse events, including new risks, are increasing.Research Question:How many adverse effects are reported with the use of newly available PFA systems?Aims:Quantify and describe the adverse events from PFA reported to date in the Food and Drug Administration’s (FDA) Manufacturer and User Facility Device Experience (MAUDE) database.Methods:We searched the U.S. FDA’s MAUDE database for all reports filed with the code “QZI”, which is the product code for PFA systems created with the first FDA approvals in February 2024. All reports from inception through April 2024 (a total of 3 months) were included in this review. Per manufacturer presentation in May 2024, approximately 1000 cases utilizing PFA had been captured in a post-market registry of the predominant commercially used technology, but the exact number of cases can not be determined from MAUDE data.Results:A total of 217 adverse events were reported over the first 3 months of US approval, with 91 of these considered patient injuries. These injuries included 10 cases of cardiac tamponade, 7 reports of postoperative arrhythmia, 6 instances of device-related tissue entrapment, 5 cases of hemolysis with impaired renal function, 5 cases of stroke or TIA, including both embolic and hemorrhagic, 3 cases of intraoperative heart block, 2 coronary spasms, and 2 cases of intraoperative ST elevation.(Figure)Of the 91 reported patient safety events, 46 required hospitalization, 13 cases required temporary pacing, 11 required pericardiocentesis, 4 required dialysis, 4 required cardiothoracic surgery, and 2 required cardioversion.Conclusions:A number of adverse events have been reported to the MAUDE database in the first 3 months of FDA approval of PFA. The cardiac electrophysiology community should remain vigilant to ensure that the benefit-risk profile remains acceptable for patient safety.

Circulation, Volume 150, Issue Suppl_1, Page A4146295-A4146295, November 12, 2024. Background:Previous studies have highlighted the impact of sex differences on the outcomes of patients admitted for ST-elevation myocardial infarction (STEMI). However, there is limited evidence as to whether there is a difference in the outcomes between females and male STEMI patients who have a concomitant diagnosis of chronic kidney disease (CKD) and end-stage renal disease (ESRD).Research Question:Does sex affect the outcomes for STEMI patients with concomitant CKD and ESRD?Methods:This is a retrospective population-based cohort study that uses the National Inpatient Sample database. CKD patients in the United States hospitalized for STEMI were identified using the International Classification of Diseases, Ninth and Tenth Revision (ICD-9 and 10) codes. Inclusion criteria were adult patients who were hospitalized from 2012 to 2020. A subset of patients with ESRD were also identified. Multivariate regression analysis was performed, with the model adjusted for age and comorbidities. The primary outcome of interest was in-hospital mortality. Secondary outcomes evaluated included ischemic stroke, major bleeding complications, pressor requirement, permanent pacemaker implantation, percutaneous coronary intervention, coronary artery bypass grafting, surgery, pericardiocentesis, mechanical circulatory support, and mechanical ventilation.Results:A total of 1,283,255 STEMI patients without CKD, 158,715 STEMI patients with CKD, and 22,690 STEMI patients with ESRD were identified and analyzed. Among patients with STEMI and CKD, females demonstrated higher in-hospital mortality compared to male counterparts (16.7% vs 12.7%, aOR=1.13, 95% CI: 1.05-1.21, p

Circulation, Volume 150, Issue Suppl_1, Page A4139904-A4139904, November 12, 2024. Background:Atrial Fibrillation (AF) in patients with metabolic syndrome is a substantial health concern among older adults in the United States. This study investigated trends and disparities in AF mortality among older adults aged 65 and older with metabolic syndrome from 1999-2020.Methods:We used the Centers for Disease Control database for mortality statistics with an underlying cause of death of AF in metabolic syndrome (ICD code I48 for AF and scattered codes indicating metabolic syndrome i.e. E10-14, E66, E78, E88, I10) between the years 1999 – 2020. Age-adjusted mortality rates (AAMR) were calculated per 100,000 deaths. The AAMR were assessed by demographic variables, including race, geographic density, sex, age, and US Census Region. Temporal trends were evaluated using Joinpoint regression software. Average annual percent change (AAPC) was considered statistically significant if p < 0.05.Results:Between 1999 and 2020, AF in metabolic syndrome caused 944,960 deaths among U.S. adults aged 65+. Most deaths occurred in medical facilities (35.8%). The overall AAMR for AF in metabolic syndrome-related deaths rose from 36.6 in 1999 to 173.4 in 2020, with an AAPC of 6.48 (95% CI: 5.07 to 7.77, p < 0.000001). A significant increase was noted from 1999 to 2001 (APC: 26.58; 95% CI: 6.04 to 43.91, p < 0.000001), followed by a continued rise from 2001 to 2020 (APC: 4.56; 95% CI: 3.60 to 5.15, p = 0.012797). Older men had higher AAMRs than older women (116.0 vs 92.3). Among racial/ethnic groups, White population had the highest AAMRs (108.8) and AAPC (6.70; 95% CI: 5.23 to 7.95), followed by American Indians/Alaska Natives (81.7), Blacks (74.1), Hispanics (68.2), and Asians (61.6). AAMRs varied by state, from 61.1 in Nevada to 170.0 in Vermont. The Western region had the highest average AAMR (116.7). Nonmetropolitan areas had slightly higher AAMRs than metropolitan areas (113.0 vs. 99.9).Conclusion:The analysis reveals a dramatic fourfold increase in AF-related mortality within metabolic syndrome among older U.S. adults over two decades. This substantial rise in mortality rates underscores the urgent need for targeted interventions and strategies to address these trends. By addressing structural barriers to quality healthcare and health disparities, we can effectively counter this concerning trend and achieve positive outcomes for this vulnerable group.

Circulation, Volume 150, Issue Suppl_1, Page A4117772-A4117772, November 12, 2024. Background:Aortic valve calcium (AVC) is strongly associated with an increased risk for severe aortic stenosis (AS). The prevalence of AVC increases with age affecting 40-50% of individuals ≥80 years. The impact of age on the progression of AVC and its association with incident AS remains unknown.Methods:Our study included 6,810 participants (52.9% women) free of cardiovascular disease between ages 45 and 84 from the Multi-Ethnic Study of Atherosclerosis. AVC was measured using non-contrast cardiac CT at Visit 1. Progression was calculated as the change in AVC divided by years between CT scans with up to 10 years between scans. Long term incident AS was adjudicated using medical chart review and echocardiogram data from Visit 6 with a median follow up of 16 years. Multivariable adjusted 1) linear regression was used to examine AVC progression and 2) multivariable adjusted Cox proportional hazards ratios (HR) were used to examine the association of AVC with incident AS.Results:The prevalence of AVC >0 was 4.9% among participants 0, the median AVC was 34.1 (IQR 13-1,113) for participants 0 was associated with significantly increased risk of incident AS for both younger (HR 13.37; 95% CI 5.67-31.52) and older participants (HR 10.59, 95% CI 6.77-16.56).Conclusion:We observed a similar progression of AVC for younger versus older persons after adjusting for baseline AVC burden. Additionally, AVC >0 independently conferred at least a ten-fold higher risk for severe AS among both younger and older participants. These findings demonstrate that the AVC progression is primarily associated with baseline AVC burden and that AVC is a strong marker of risk for severe AS for both younger and older persons.

Circulation, Volume 150, Issue Suppl_1, Page A4134768-A4134768, November 12, 2024. Backgrounds:Heart failure (HF) associated with coronary artery disease (CAD) is a significant contributor to mortality in the elderly population of the United States. This study examines trends in HF in CAD-related mortality among adults aged 65 and older, focusing on geographic, gender, and racial/ethnic disparities from 1999 to 2020.Methods:A retrospective analysis was performed using the CDC WONDER database death certificates from 1999 to 2020. Age-adjusted mortality rates (AAMRs), annual percent change (APC), and average annual percentage change (AAPC) were calculated per 100,000 persons, stratified by year, sex, race/ethnicity, and geographical region.Results:Between 1999 and 2020, there were 6,571,263 deaths attributed to coronary artery disease (CAD) and 6,135,540 deaths related to Heart Failure (HF) in the US. Among adults aged 65 and older, HF in CAD caused 1,597,451 deaths, with 37.1% occurring in medical facilities and 30.3% in nursing homes. The AAMRs for HF in CAD decreased from 241.7 in 1999 to 156.2 in 2020 (AAPC: -2.23, p < 0.000001). This reduction was significant from 1999 to 2014, followed by a slight increase from 2014 to 2020. Men consistently had higher AAMRs than women (227.4 vs. 137.1), with women experiencing a more significant decline in rates (AAPC: -3.23, p < 0.000001). Racial disparities revealed the highest AAMRs among Whites (183.0), followed by American Indians/Alaska Natives (153.7), Blacks (134.6), Hispanics (123.7), and Asians/Pacific Islanders (81.6). The most significant reductions were observed in Hispanics (AAPC: -2.68, p < 0.000001). Geographically, AAMRs varied, ranging from 92.1 in Hawaii to 257.3 in West Virginia, with the Midwest showing the highest mortality (191.0). Nonmetropolitan areas exhibited higher AAMRs than metropolitan areas (202.6 vs. 166.1), although both showed moderate declines over time, more pronounced in urban areas (AAPC: -2.41, p < 0.000001).Conclusion:The study uncovers notable variances in HF in CAD-related mortality among elderly individuals in the United States based on race, gender, and geographic location. While the decrease in AAMRs from 1999 to 2014 indicates progress in cardiovascular care, the subsequent rise from 2014 to 2020 and enduring disparities call for specific public health measures to tackle these inequalities.

Circulation, Volume 150, Issue Suppl_1, Page A4142110-A4142110, November 12, 2024. Background:Coronary artery calcium (CAC) scans contain more actionable information than the Agatston CAC score. We have previously shown in the Multi-Ethnic Study of Atherosclerosis (MESA) that AI-enabled left atrial (LA) volumetry in CAC scans (AI-CAC) enabled prediction of atrial fibrillation (AF) as early as one year. Furthermore, we have recently shown adding AI-CAC LA volumetry to CHA2DS2-VASc risk score improved stroke prediction in MESA. In this study we evaluated the performance of AI-CAC LA volumetry versus LA measured by human experts using cardiac magnetic resonance imaging (CMRI) for predicting AF and stroke, and compared them with CHARGE-AF risk score, Agatston score, and NT-proBNP.Methods:We used 15-year outcomes data from 3552 asymptomatic individuals (52.2% women, age 61.7±10.2 years) who underwent both CAC scans and CMRI in the MESA baseline examination. We have applied the AutoChamberTM(HeartLung.AI, Houston, TX) component of AI-CAC to 3552 CAC scans. CMRI LA volume was previously measured by human experts. Data on NT-proBNP, CHARGE-AF risk score and the Agatston score were obtained from MESA. Discrimination was assessed using the time-dependent area under the curve (AUC).Results:Over 15 years follow-up, 562 cases of AF and 140 cases of stroke accrued. The AUC for 15-yearAF predictionby AI-CAC LA volume (0.801) was comparable to CMRI LA volume (0.797) and significantly higher than Agatston CAC Score (0.687) and NT-proBNP (0.704). Similarly, the AUC for 15-yearstrokepredictionfor AI-CAC volumetry (0.761) was comparable to CMRI volumetry (0.751) and significantly higher than NT-proBNP (0.631) and Agatston CAC Score (0.646).

Higher inactive MGP, dephosphorylated-uncarboxylated (dp-ucMGP), is positively associated with vascular calcification, possibly portending cardiovascular events. The objective was to determine the association of dp-ucMGP with incident cardiovascular disease (CVD) events and mortality in the Multi-Ethnic Study of Atherosclerosis (MESA).Methods:MESA is a cohort study of 45-84 year-old individuals enrolled between 2000-02 with adjudicated outcomes through 2019. Dp-ucMGP was measured at baseline in n=2663 participants with cardiac computed tomography at Exams 1 (2000-02) and 5 (2010-12). Using age-stratified Cox proportional hazard models, adjusted for sex, race-ethnicity, body mass index, systolic blood pressure, statin use, anti-hypertensive medication use, smoking status, physical activity, alcohol use, diabetes, high density lipoprotein, low density lipoprotein, triglycerides, phosphate, and estimated glomerular filtration rate, we determined the association of dp-ucMGP with risk of all CVD (mean follow-up 16+4 years), hard CVD (17+3 years), hard CHD (17+3 years), and all-cause mortality (18+2 years).Results:The youngest age quartile (45-53-years-old) with higher dp-ucMGP levels (520-2934 pmol/L) had an increased risk of all CVD (HR 3.01 [95% CI 1.56, 5.80], p=0.001), hard CVD (HR 2.78 [95% CI 1.29, 6.02], p=0.009), hard CHD (HR 3.37 [95% CI 1.29, 8.81], p=0.013) and all-cause mortality (HR 2.69 [95% CI 1.06, 6.79], p=0.037) compared to dp-ucMGP levels between 150-519 pmol/L in maximally adjusted models. There was no relationship with any outcomes for the other age quartiles (Table).Conclusions:Middle aged individuals with elevated dp-ucMGP levels ( >520 pmol/L) had an increased risk of incident CVD, CHD, and all-cause mortality.

Circulation, Volume 150, Issue Suppl_1, Page A4144666-A4144666, November 12, 2024. Background:There is limited data on the safety and efficacy of ventricular tachycardia (VT) ablation in patients with chronic kidney disease (CKD). We examined the outcomes of patients with CKD undergoing VT ablation in a nationally representative cohort of patients.Methods:The National Inpatient Sample Database (NIS) was analyzed from 2018 to 2021 to identify patients ≥18 years old with VT undergoing ablation. Patients with atrial fibrillation, atrial flutter, supraventricular tachycardia, or pre-excitation syndrome were excluded. Patients were divided into those with CKD and without CKD. A multivariable logistic regression model was utilized to assess the association of CKD with in-hospital mortality and outcomes after adjusting for confounders.Results:Our cohort included 1608 VT ablation procedures, of which 428 (27%) were performed on CKD patients. Mean age was 63 (±13) years, 318 (19%) were female, and 1194 (74%) were White. 1475 (92%) of the procedures were done at an urban teaching hospital, and 1240 (77%) at a private non-profit hospital. On multivariable analysis, CKD was associated with significantly higher odds of death (adjusted odds ration [aOR]: 3.43; 95% confidence interval [CI]: 1.79-6.5; p=0.0002), acute decompensated heart failure (aOR: 3.1; 95% CI 2.24-4.56; p
