Background and Objectives: The epidemiological data regarding mortality rates of adults with sarcoidosis and non-ischemic cardiovascular disease (CVD) are limited. A retrospective observational analysis was conducted to identify trends and disparities related to sarcoidosis and non-ischemic cardiovascular disease mortality among the adult US population from 1999 to 2022. Methods: We used the Centers for Disease Control and Prevention (CDC) WONDER database to extract death certificate data for the adult US population (≥25 years). The age-adjusted mortality rates (AAMRs) per 100,000 persons were calculated, and annual percent changes (APCs) were determined using Joinpoint. Results: Between 1999 and 2022, 23,642 deaths were identified related to non-ischemic CVD + sarcoidosis. The overall AAMR increased from 0.2 (95% CI, 0.2 to 0.3) in 1999 to 0.5 (95% CI, 0.5 to 0.6) in 2022. Females had a higher AAMR than males (0.6 vs. 0.5). Non-Hispanic (NH) blacks had the highest AAMR, followed by NH whites and Hispanic or Latinos. The southern region had the highest AAMR (0.7: 95% CI, 0.6–0.7), followed by the Midwest (0.6, 95% CI, 0.54–0.669), the Northeast (0.5, 95% CI, 0.5 to 0.6), and the West (0.4; 95% CI, 0.3–0.4). Urban and rural areas had comparable mortality rates (0.5 vs. 0.6). People aged 65+ had the highest AAMRs. Conclusions: The overall mortality rates for non-ischemic CVD and sarcoidosis have increased in the US from 1999 to 2022. Females and NH blacks had higher AAMRs, while a minimal variation was observed based on geographical regions. Early diagnosis and prompt management are the keys to reducing the mortality burden of non-ischemic CVD plus sarcoidosis.

Background: Heart transplantation (HTx) is a life-saving procedure for patients with end-stage heart disease. Sarcoid myocarditis (SM) is a rare condition characterized by granulomatous inflammation of the myocardium. The mainstay of therapy is immunosuppression but the incidence of cardiac sarcoidosis leading to advanced heart failure is increasing. HTx is a valid option in such cases however post-HTx outcomes in sarcoid population have been poorly investigated. Methods: A retrospective analysis of the National Inpatient Sample (NIS) from 2016 to 2021 was conducted. Outcomes compared between sarcoid and non-sarcoid HTx groups were mortality, length of stay (LOS), hospital charges, transplant rejection and graft failure. Mann-Whitney U test was utilized to compare differences between non-parametric variables, while multivariable logistic regression was applied to adjust for confounders. Results: During our study period a total of 17,635 patients underwent HTx out of which 235 (0.013%) had HTx due to sarcoid myocarditis. Multivariable analysis revealed a comparable mortality between sarcoid and non-sarcoid HTx (Adjusted Mortality: aOR 1.35; CI 0.40-4.56; p=0.61). Median length of stay in sarcoid myocarditis group was 29[IQR19-55] vs 28[IQR16-50] p=0.57. Total hospitalization charges were also comparable 956,893[IQR 649,498-1,451,199] vs 800,898[IQR 533,047-1,349,074], p=0.18. There was no significant increase in transplant rejection (aOR 1.43; CI 0.64-3.20; p=0.37) or graft failure (aOR 1.92; CI 0.55- 6.70; p=0.30) in the sarcoid myocarditis group (Table 1, Table 2). Conclusion: Sarcoid myocarditis patients undergoing HTx showed comparable mortality, LOS, total hospital charges, transplant rejection, or graft failure rates to patients undergoing HTx for other causes.While these findings suggest that SM, while rare, does not adversely affect transplant outcomes, we strongly advocate for more studies to adjust for limitations.

Background: The highly arrhythmogenic nature of cardiac sarcoidosis (CS) leads to high morbidity and mortality, the rates of which may be higher in COVID-19 patients. This study aimed to evaluate the outcomes of CS patients admitted to hospitals with COVID-19. Methods: The study utilised the 2020–2021 National Inpatient Sample database, examining primary COVID-19 cases in adults aged older than or equal to 18 years. Those with CS were identified using ICD-10 code “D86.85” and compared with and without propensity matching (1:10) to those without CS for baseline characteristics and primary outcomes of acute kidney injury (AKI), use of mechanical ventilation, cardiac arrest and mortality. Results: In total, 2 543 912 COVID-19 cases were identified. Before propensity matching, CS patients were more likely to be younger (58.0 vs. 64.0 years, P<0.01), male (64.0% vs. 52.6%, P=0.011), of Black ethnicity (60.0% vs. 15.9%, P<0.01), exhibit higher Charlson Comorbidity Index (CCI) scores (3.00 vs. 1.00, P<0.01) and had a higher incidence of in-hospital cardiac arrest (aOR 2.649, 95% CI 1.366–5.134, P=0.004). After propensity matching (CS, N=95; non-CS, N=875), those with CS were at a statistically significant reduced risk of AKI (aOR 0.484, P=0.01); however, the outcomes of death, cardiac arrest, mechanical ventilation, length of stay (LOS) and healthcare costs did not reach significance. Conclusion: In a propensity-matched cohort admitted with COVID-19, CS patients had a reduced risk of AKI, but comparable LOS, rates of cardiac arrest, mechanical ventilator use, and mortality. Future research is warranted to develop evidence-based guidelines for managing COVID-19 in patients with CS.

AbstractBackgroundCardiac tamponade or pericardial tamponade (PT) can be a complication following invasive cardiac procedures.MethodsPatients who underwent various procedures in the cardiac catheterization lab (viz. coronary interventions) were identified using the International Classification of Diseases, Ninth and Tenth Edition, Clinical Modification (International classification of diseases [ICD]‐9‐Clinical modification [CM] and ICD‐10‐CM, respectively) from the Nationwide Inpatient Sample (NIS) database. Patient demographics, presence of comorbidities, PT‐related events, and in‐hospital death were also abstracted from the NIS database.ResultsThe frequency of PT‐related events in the patients undergoing CI from 2010 to 2017 ranged from 3.3% to 8.4%. Combined in‐hospital mortality/morbidity of PT‐related events were higher with increasing age (odds ratio [OR] [95% CI]: chronic total occlusion (CTO) = 1.19 [1.10‐1.29]; acute coronary syndrome (ACS) = 1.21 [1.11‐1.33], both p < 0.0001) and female sex (OR [95%CI]: CTO = 1.70 [1.45‐2.00]; ACS = 1.72 [1.44‐2.06], both p < 0.0001). In‐hospital mortality related to PT‐related events was found to be 8.5% for coronary procedures. In‐hospital mortality was highest amongst the patients undergoing percutaneous transluminal coronary angioplasty (PTCA) for ACS (ACS vs. non‐CTO PTCA vs. CTO PTCA: 15.7% vs. 10.4% and 14.4%, p < 0.0001 and ACS vs. non‐CTO PTCA vs. CTO PTCA: 12.1% vs. 8.1% and 5.6%, p = 0.0001, respectively).ConclusionsIn the real‐world setting, PT‐related events in CI were found to be 3.3%−8.4%, with in‐hospital mortality of 8.5%. The patients undergoing PTCA for ACS were found to have highest mortality. Older patients undergoing CTO PTCA independently predicted higher mortality.

AbstractIntroductionIn patients with cardiac sarcoidosis (CS), implantable cardioverter‐defibrillators (ICDs) are important for preventing sudden cardiac death. This study aimed to investigate sex disparities in CS patients undergoing ICD implantation.MethodsThe 2016–2020 National Inpatient Sample (NIS) database compared the characteristics and outcomes of males and females with CS receiving ICDs.ResultsAmong 760 CS patients who underwent inpatient ICD implantation, 66.4% were male. Males were younger (55.0 vs. 56.9 years, p < .01), had higher rates of diabetes (31.7% vs. 21.6%, p < .01) and chronic kidney disease (CKD) (16.8% vs. 7.8%, p < .01) but lower prevalence of atrial fibrillation (AF) (11.9% vs. 23.5%, p < .01), sick sinus syndrome (4.0% vs. 7.8%, p = .024), ventricular fibrillation (VF) (9.9% vs. 15.7%, p = .02), and black ancestry (31.9% vs. 58.0%, p < .01). Unadjusted major adverse cardiovascular events (MACE), defined as a composite of in‐hospital death, myocardial infarction (MI), and ischemic stroke, was higher in females (11.8% vs. 6.9%, p = .024), but when adjusted for age and tCharlson Comorbidity Index (CCI), females demonstrated significantly lower odds of experiencing MACE (aOR: 0.048, 95% CI: 0.006–0.395, p = .005). Incidence of acute kidney injury (AKI) post‐ICD was significantly lower in females (15.7% vs. 23.8%, p = .01) as was the adjusted odds (aOR: 0.282, 95% CI: 0.146–0.546, p < .01). There was comparable mean length of stay and hospital charges.ConclusionICD utilization in CS patients is more common among males, who have a higher prevalence of diabetes and CKD but a lower prevalence of AF, sick sinus syndrome, and VF. Adjusted MACE and AKI were significantly lower in females.

Introduction: The impact of COVID-19 was felt across cardiology as resources were redirected to critical care, delaying elective cardiology procedures. Hypothesis: To evaluate differences in outcomes of cardiac implantable electronic device (CIED) procedures in 2020 (height of COVID) vs. 2016-2019 (pre-COVID). Methods: Adults >= 18 years undergoing CIED procedures were identified from National Inpatient Sample Databases (NIS) 2016-2020. Complications and mortality were assessed based on the type of device: Permanent Pacemaker (PPM); Implantable Cardioverter Defibrillator (ICD); Cardiac Resynchronization Therapy with Pacemaker (CRT-P) or defibrillator (CRT-D): Leadless PPM; Generator explant (GE), and Lead extraction (LE). Results: A 13.8% drop in CIED admissions was recorded between 2019 and 2020 (p<0.01). Fewer procedures involving PPM, ICD, CRT-P, CRT-D, LE, and GE were observed between 2019 and 2020. Leadless PPM utilization rose consistently between 2016-2020 (47.6% increase during 2020 vs 2019)(Figure). In 2020, a higher proportion of patients were classified with a Charlson Comorbidity Index score of ≥3 (severe) (47.4% in 2020 vs. 42.9% in 2016-2019, p<0.01). The table shows significantly higher complications during CIED implants with no changes in mortality related to procedures. Conclusions: Patients admitted for CIED implants in 2020 had more severe comorbidities and expressed considerable differences in complications than pre-COVID era (2016-2019), but mortality remained unchanged. Leadless PPM use increased during pandemic, as against a decrease in the use of other CIEDs.

Introduction: While Coronavirus disease 2019 (COVID-19) primarily affects the respiratory system but can impact the cardiovascular system can triggering various complications. Hypothesis: To investigate the trend in age-adjusted mortality rates (AAMRs) in patients with atrial fibrillation(AF) among COVID-19-positive patients (CPP) by race and sex. Methods: Trends in AAMRs (per 100,000) from all-cause in patients with AF between April to December 2016-2020 were evaluated via the National Inpatient Sample and the US Census Bureau. The AAMRs among CPP with AF in 2020 was also evaluated between racial and sex cohorts. Results: A gradual rise in AAMR(all causes) in patients with AF was observed between 2016-2019, with a 49.4% overall rise between 2019(271 per 100,000) and 2020(405 per 100,000) ( Table 1a and Figure ). Around 250475 COVID-19-positive patients had AF, and 24.2% of cases did not survive their hospitalization (vs. 10.9% in those without AF, p<0.01, aOR 1.457, 95% CI 1.438-1.477). Among CPP males and females with AF that died, White females and males were the oldest, while Black males and females reported the highest mean Charlson Comorbidity Index (CCI) score ( Table 1b ).Furthermore, among the CPP with AF in 2020, Hispanics reported a higher AAMR (119.6 per 100,000) than Whites(111.1 per 100,000) and Blacks(101.9 per 100,000). AAMRs in males were higher in Hispanic males (144.8 per 100,000), followed by White males (129.7 per 100,000), and Black males (110 per 100,000). However, the AAMRs in females were highest in Black females (91.3 per 100,000), followed by White females (88.3 per 100,000) and Hispanic females (87.0 per 100,000). ( Table 1c ) Conclusions: AAMRs in patients with AF are on the rise and a sharp growth was seen during the first year of the pandemic. AAMRs among CPP patients with AF were highest among Black females and Hispanic males, while White males and females were oldest and Black males and females reported the highest CCI scores.
