ABSTRACTBackgroundChimeric Antigen Receptor (CAR) T‐cell therapy has arisen as a revolutionary treatment for hematologic malignancies. Our study aimed to evaluate how sex differences affect outcomes and complications following CAR T‐cell therapy.MethodsUtilizing the Nationwide Readmissions Database (2018–2020), we identified patients and divided them into male and female groups. Hospital outcomes and complications were compared among these two groups after propensity score matching to match groups based on comorbidities, producing two comparable cohorts.ResultsWe analyzed 2928 patients (1832 males, 62.6%, mean age 60.3 ± 13.7 years; 1096 females, 37.4%, mean age 59.1 ± 13.8 years). After propensity score matching (1:1ratio), 1092 males and females were compared. There were no significant sex differences in early mortality (adjusted odd ratios (aOR): 1.04 [95% CI 0.69–1.57]), 30‐day readmissions (aOR: 1.05 [95% CI 0.86–1.30]), or nonhome discharge (aOR: 0.89 [95% CI 0.60–1.31]). Females had higher odds of leukopenia (aOR: 1.26 [95% CI 1.06–1.50]) but lower odds of acute kidney injury (aOR: 0.68 [95% CI 0.52–0.88]).ConclusionsNo sex differences were found in hospital outcomes, including early mortality, 30‐day readmission, and nonhome discharge after CAR T‐cell therapy.

Background: The optimal timing of pacemaker reimplantation following transvenous lead removal (TLR) of infected cardiac implantable electronic device (CIED) remains unclear. Objective: Our study aimed to assess the impact of timing to pacemaker reimplantation after TLR of infected CIED on hospital outcomes. Method: Using the Nationwide Readmissions Database, patients aged ≥18 years who underwent new pacemaker implantation with percutaneous approach following TLR of infected CIED from 2017 to 2020 were identified. The study population was stratified based on the timing of pacemaker reimplantation following TLR of infected CIED: early (<5 days) vs delayed (≥5 days). Weighted-propensity-score matched conditional multivariable logistic regressions were performed to determine the impact of the timing on various outcomes. Results: In our study, 469 (66.9%) patients received early device reimplantation, and 232 (33.1%) patients received delayed device reimplantation (≥5 days). Post-procedurally, patients in the delayed group had a higher risk of prolonged hospital stay (95% CI OR: 42.37 (6.36 – 282.11); p<0.01) and non-home discharge (95% CI OR: 2.00 (1.35 – 2.95), p<0.01). There was no significant difference between both groups in the early mortality, 30-day readmission, and procedural complications. Conclusion: Our study suggests that time-to-device reimplantation from TLR of infected CIED did not affect the overall short-term in-hospital outcomes. However, delayed device reimplantation was associated with a higher rate of prolonged hospital stay and non-home discharge.

AbstractBackgroundThe impact of atrial fibrillation (AF) among patients with amyloidosis on in‐hospital outcomes is not well‐established. We aimed to examine in‐hospital outcomes among patients admitted with a primary diagnosis of AF with and without amyloidosis.Methods and ResultsWe queried the Nationwide Readmissions Database to compare the in‐hospital outcomes among AF patients with and without amyloidosis. Our study demonstrated that in‐hospital all‐cause mortality, adverse events, and 30‐day readmission were comparable between the two groups.ConclusionsPatients with AF and concurrent amyloidosis did not have worse in‐hospital outcomes than those with AF alone.

e15543 Background: In the last two decades, colorectal cancer (CRC) mortality has been decreasing in the United States (US). However, the mortality trends for the different subtypes of CRC, including different sides of colon, rectosigmoid, and rectal cancer remain unclear. Methods: We analyzed death certificate data from CDC WONDER from 1999 to 2020. We calculated age-adjusted mortality rates (AAMR) per 100,000 individuals of CRC and its different subtypes and examined the trends over time by estimating the average annual percent change (AAPC) using the Joinpoint Regression Program. Results: From 1999 to 2020, 1,166,099 deaths were attributed to CRC, of which 957,182 deaths (82.08%) were due to colon cancer, 148,862 deaths (12.77%) from rectal cancer, and 60,055 deaths (5.15%) from rectosigmoid cancer. The overall CRC rates decreased significantly from 26.42 (95% CI, 26.20-26.64) to 15.98 (95% CI, 15.84-16.12) per 100,000 individuals, with AAPC of -2.41 (95% CI, -2.55, -2.27). However, the AAMR of rectosigmoid cancer increased significantly from 0.82 (95% CI, 0.78 -0.86) to 1.08 (95% CI, 1.04-1.11) per 100,000 individuals and the AAMR of right-sided colon cancer increased from 0.57 (95% CI, 0.54-0.60) to 0.70 (95% CI, 0.67-0.73) per 100,000 individuals, with AAPC of +1.10 (95%, 0.21-2.00) and +2.06 (95% CI, 0.85 - 3.27) respectively. Men had higher AAMR of CRC than women (23.90 [95% CI, 23.84-23.96] vs. 17.03 [95% CI, 16.99-17.08] per 100,000 individuals). African Americans had the highest AAMR of CRC (26.93 [95% CI, 26.79-27.07]), followed by Whites (19.60 [95%, 19.56-19.64] per 100,000 individuals), American Indians (14.53 [95%, 14.15-14.92] per 100,000 individuals), and Asians (13.04 [95%, 12.89-13.19] per 100,000 individuals). The overall AAMR of CRC decreased for those aged ≥ 50 years but increased significantly from 1.02 to 1.58 per 100,000 individuals for those aged 15-49 years, with an AAPC of +0.75. The AAMR from CRC was the highest in the Midwest (21.04 [95% CI, 20.96-21.12] per 100,000 individuals), followed by the South (20.51 [95% CI, 20.44-20.57]), the Northeast (20.30 [95% CI, 20.22-20.38] per 100,000 individuals), and the West (18.03 [95% CI, 17.95-18.10] per 100,000 individuals). Rural populations had higher AAMR than urban populations (22.40 [95% CI, 22.30-22.49] vs. 19.60 [95%, 19.56-19.64] per 100,000 individuals). Conclusions: Although overall CRC mortality declined, there were rising trends in young-onset CRC, rectosigmoid cancer, and right-sided colon cancer. Disparities persist in terms of sex, race, geographic region, and urbanization level, emphasizing the need for targeted public health measures.

Background Percutaneous heart valve procedures have been increasingly performed over the past decade, yet real‐world mortality data on valvular heart disease (VHD) in the United States remain limited. Methods and Results We queried the Centers for Disease Control and Prevention's Wide‐Ranging Online Data for Epidemiologic Research database among patients ≥15 years old from 1999 to 2020. VHD and its subtypes were listed as the underlying cause of death. We calculated age‐adjusted mortality rate (AAMR) per 100 000 individuals and determined overall trends by estimating the average annual percent change using the Joinpoint regression program. Subgroup analyses were performed based on demographic and geographic factors. In the 22‐year study, there were 446 096 VHD deaths, accounting for 0.80% of all‐cause mortality (56 014 102 people) and 2.38% of the total cardiovascular mortality (18 759 451 people). Aortic stenosis recorded the highest mortality of VHD‐related death in both male (109 529, 61.74%) and female (166 930, 62.13%) populations. The AAMR of VHD has declined from 8.4 (95% CI, 8.2–8.5) to 6.6 (95% CI, 6.5–6.7) per 100 000 population. Similar decreasing AAMR trends were also seen for the VHD subtypes. Men recorded higher AAMR for aortic stenosis and aortic regurgitation, whereas women had higher AAMR for mitral stenosis and mitral regurgitation. Mitral regurgitation had the highest change in average annual percent change in AAMR. Conclusions The mortality rate of VHD among the US population has declined over the past 2 decades. This highlights the likely efficacy of increasing surveillance and advancement in the management of VHD, resulting in improved outcomes.

Background Despite significant cardiac involvement in sarcoidosis, real‐world data on death due to cardiovascular disease among patients with sarcoidosis is not well established. Methods and Results We queried the Centers for Disease Control and Prevention's Wide‐Ranging Online Data for Epidemiologic Research database for data on patients with sarcoidosis aged ≥25 years from 1999 to 2020. Diseases of the circulatory system except ischemic heart disease were listed as the underlying cause of death, and sarcoidosis was stated as a contributing cause of death. We calculated age‐adjusted mortality rate (AAMR) per 1 million individuals and determined the trends over time by estimating the annual percentage change using the Joinpoint Regression Program. Subgroup analyses were performed on the basis of demographic and geographic factors. In the 22‐year study period, 3301 cardiovascular deaths with comorbid sarcoidosis were identified. The AAMR from cardiovascular deaths with comorbid sarcoidosis increased from 0.53 (95% CI, 0.43–0.65) per 1 million individuals in 1999 to 0.87 (95% CI, 0.75–0.98) per 1 million individuals in 2020. Overall, women recorded a higher AAMR compared with men (0.77 [95% CI, 0.74–0.81] versus 0.58 [95% CI, 0.55–0.62]). People with Black ancestry had higher AAMR than people with White ancestry (3.23 [95% CI, 3.07–3.39] versus 0.39 [95% CI, 0.37–0.41]). A higher percentage of death was seen in the age groups of 55 to 64 years in men (23.11%) and women (21.81%), respectively. In terms of US census regions, the South region has the highest AAMR from cardiovascular deaths with comorbid sarcoidosis compared with other regions (0.78 [95% CI, 0.74–0.82]). Conclusions The increase of AAMR from cardiovascular deaths with comorbid sarcoidosis and higher cardiovascular mortality rates among adults aged 55 to 64 years highlight the importance of early screening for cardiovascular diseases among patients with sarcoidosis.

Abstract In the last two decades, colorectal cancer (CRC) mortality has been decreasing in the United States. However, the mortality trends for the different subtypes of CRC, including different sides of colon, rectosigmoid, and rectal cancer remain unclear. We analyzed the mortality trends of different subtypes of CRC based on Centers for Disease Control and Prevention's Wide‐Ranging Online Data for Epidemiologic Research data from 1999 to 2020. We calculated age‐adjusted mortality rates (AAMR) per 100,000 individuals and examined the trends over time by estimating the average annual percent change (AAPC) using the Joinpoint Regression Program. Our study shows that the overall CRC rates decreased significantly from 26.42 to 15.98 per 100,000 individuals, with an AAPC of −2.41. However, the AAMR of rectosigmoid cancer increased significantly from 0.82 to 1.08 per 100,000 individuals, with the AAPC of +1.10. Men and Black individuals had the highest AAMRs respectively (23.90 vs. 26.93 per 100,000 individuals). The overall AAMR of CRC decreased for those aged ≥50 years but increased significantly from 1.02 to 1.58 per 100,000 individuals for those aged 15–49 years, with an AAPC of +0.75. Rural populations had a higher AAMR than the urban populations (22.40 vs. 19.60 per 100,000 individuals). Although overall CRC mortality declined, rising trends in young‐onset CRC and rectosigmoid cancer warrant attention. Disparities persist in terms of sex, race, and geographic region, and urbanization level, emphasizing the need for targeted public health measures.

AbstractBackgroundThe real‐world data on the safety profile of transvenous lead extraction (TLE) for infected cardiac implantable electronic devices (CIED) among elderly patients is not well‐established. This study aimed to evaluate the hospital outcomes between patients of different age groups who underwent TLE for infected CIED.MethodUsing the Nationwide Readmissions Database, our study included patients aged ≥18 years who underwent TLE for infected CIED between 2017 and 2020. We divided the patients into four groups: Group A. Young (<50 years), Group B. Young intermediate (50–69 years old), Group C. Older intermediate (70–79 years old), and Group D. Octogenarian (≥80 years old). We then analyzed the in‐hospital outcome and 30‐day readmission between these age groups.ResultsA total of 10,928 patients who were admitted for TLE of infected CIED were included in this study: 982 (9.0%) patients in group A, 4,234 (38.7%) patients in group B, 3,204 (29.3%) patients in group C and 2,508 (23.0%) of patients in group D. Our study demonstrated that the risk of early mortality increased with older age (Group B vs. Group A: OR: 1.92, 95% CI: 1.19‐3.09, p < .01; Group C vs. Group A: OR: 2.47, 95% CI: 1.51‐4.04, p < .01; Group D vs. Group A: OR: 2.82, 95% CI: 1.69‐4.72, p < .01). The risk of non‐home discharge also increased in elderly groups (Group B vs. Group A: OR: 1.89; 95% CI: 1.52‐2.36; p < .01; Group C vs. Group A: OR: 2.82; 95% CI 2.24‐3.56; p < .01; Group D vs. Group A: OR: 4.16; 95% CI: 3.28‐5.28; p < .01). There was no significant difference in hospitalization length and 30‐day readmission between different age groups. Apart from a higher rate of open heart surgery in group A, the procedural complications were comparable between these age groups.ConclusionElderly patients had worse in‐hospital outcomes in early mortality and non‐home discharge following the TLE for infected CIED. There was no significant difference between elderly and non‐elderly groups in prolonged hospital stay and 30‐day readmission. Elderly patients did not have a higher risk of procedural complications.

AbstractBackgroundThe real‐world data on the safety profile of ventricular tachycardia (VT) ablation among elderly patients is not well‐established. This study aimed to evaluate the procedural outcomes among those aged 18–64 years versus those aged ≥65 years who underwent catheter ablation of VT.MethodUsing the Nationwide Readmissions Database, our study included patients aged ≥18 years who underwent VT catheter ablation between 2017 and 2020. We divided the patients into non‐elderly (18–64 years old) and elderly age groups (≥65 years old). We then analyzed the in‐hospital procedural outcome and 30‐day readmission between these two groups.ResultsOur study included 2075 (49.1%) non‐elderly patients and 2153 (50.9%) elderly patients who underwent VT ablation. Post‐procedurally, elderly patients had significantly higher rates of prolonged index hospitalization (≥7 days; 35.5% vs. 29.3%, p < .01), non‐home discharge (13.4% vs. 6.0%, p < .01), 30‐day readmission (17.0% vs. 11.4%, p < .01), and early mortality (5.5% vs. 2.4%, p < .01). There was no significant difference in the procedural complications between two groups, namely vascular complications, hemopericardium/cardiac tamponade, cerebrovascular accident (CVA), major bleeding requiring blood transfusion, and systemic embolization. Through multivariable analysis, the elderly group was associated with higher odds of early mortality (OR: 7.50; CI 1.86–30.31, p = .01), non‐home discharge (OR: 2.41; CI: 1.93–3.00, p < .01) and 30‐day readmission (OR: 1.58; CI 1.32–1.89, p < .01).ConclusionElderly patients have worse in‐hospital outcome, early mortality, non‐home discharge, and 30‐day readmission following catheter ablation for VT. There was no significant difference between elderly and non‐elderly groups in the procedural complications.

Background: While spontaneous coronary artery dissection (SCAD) patients can present with ventricular arrhythmias (VAs), the in-hospital outcomes among these patients are not well-established. Objective: This study aimed to analyze the in-hospital outcomes of patients with SCAD and concurrent VAs, and to determine the predictors of VAs occurrence in this population. Methods: Using the Nationwide Readmissions Database, our study included patients aged 18 years or older who had SCAD between 2017 and 2020. We categorized the cohort into two groups depending on the presence of VAs during hospitalization. The in-hospital outcomes were assessed between two groups. Through multivariable analysis, we further analyzed the predictors of VAs occurrence among SCAD patients. Results: Our study included 160 (13.45%) SCAD patients with concurrent VAs and 1,030 (86.55%) SCAD patients without concurrent VAs between 2017 and 2020. SCAD patients with concurrent VA were associated with higher rates of early mortality (11.88% vs. 2.04%, p<0.01), prolonged index hospital stay (≥7 days) (31.25% vs. 12.82%, p<0.01), and non-home discharge (21.88% vs. 6.50%, p<0.01). The length of hospital stay was longer in the SCAD with concurrent VAs group (6.93 days vs. 3.73 days, p<0.01), and the median cumulative cost of hospitalization was also higher in this group ($31,450 vs. $14,664, p<0.01). SCAD with concurrent VAs patients also had poorer in-hospital adverse events. In multivariable analysis, the independent predictors for VAs occurrence among SCAD patients were chronic liver disease (aOR: 2.18; 95% CI: 1.15- 4.12, p=0.02) and heart failure (aOR: 3.40; 95%CI: 2.30- 5.02, p<0.01). Conclusion: Ventricular arrhythmias among SCAD patients were associated with poorer in-hospital outcomes. Heart failure and chronic liver disease were the predictors of VAs in SCAD patients. This highlights the importance of closely monitor and aggressive VAs management among these high-risk patients.
