ABSTRACT Background Patients with cancer undergoing cardiac implantable electronic device (CIED) implantation face unique challenges. This study evaluates the outcomes and implications of CIED implantation in this population. Methods Using data from the National Readmission Database (NRD) from 2016 to 2019, we analyzed CIED implantations in patients aged ≥18 years, categorized by cancer status: no cancer, historical cancer, and active cancer. Multivariable logistic and linear regression models assessed associations with in‐hospital, 30‐day, and 90‐day outcomes, adjusting for various patient characteristics. Results A total of 748,957 CIED procedures were analyzed among which 13.3% were in patients with historical cancer and 3.8% with active cancer. Active cancer was linked to higher odds of pacemaker implantation but lower odds for ICD and CRT devices. Patients with active cancer experienced higher index hospitalization mortality (aOR 1.68; 1.50–1.89; p < 0.001), major adverse cardiovascular events (aOR 1.07; 1.02–1.14; p = 0.01), bleeding (aOR 1.36; 1.27–1.46; p < 0.01), and sepsis‐related (aOR 1.31; 1.19–1.44; p < 0.01) complications, with increased readmission rates at 30 (aOR 1.37; 1.30–1.44; p < 0.01) and 90 days (aOR 1.37; 1.31–1.44; p < 0.01) compared to those without cancer. Historical cancer was associated with better outcomes. Key predictors of adverse outcomes included chronic heart failure, kidney disease, cerebrovascular disease, and protein‐calorie malnutrition. Conclusions Patients with active cancer undergoing CIED implantation have an increased risk of in‐hospital complications and readmissions as compared to those without cancer.

Introduction: There is a lack of data on procedural safety and outcomes in patients with rheumatic mitral valve disease (RMVD) undergoing atrial fibrillation (AF) ablation. Hypothesis: We hypothesized that the presence of RMVD may affect the outcomes of patients undergoing AF ablation and tested this hypothesis using data from a large, nationally representative sample of the US population. Methods: The National Readmissions Database (NRD) was analyzed from 2016-2019 to identify patients ≥ 18 years old undergoing AF ablation. Patients with RMVD were then identified by using ICD-10 CM codes. A multivariable logistic regression model was used to adjust for confounders. Results: Our cohort included 50,728 weighted AF ablation procedures, of which 3,500 (6.9%) patients had RMVD. Patients with RMVD were older at the time of catheter ablation, with a significantly higher percentage of females, less likely to have paroxysmal AF, and had a higher burden of comorbidities including congestive heart failure, renal failure, and hypertension. On multivariable analysis, the presence of RMVD was associated with higher odds of cardiovascular complications (adjusted odds ratio [aOR] 1.28; 95% confidence interval [CI]: 1.12-1.47; p<0.01) with no difference in the odds of in-hospital mortality or other periprocedural outcomes. Also, RMVD was associated with longer length of stay (adjusted mean difference: +1.06; 95% CI: +0.67 - +1.45; p<0.01) days and lower odds of routine home discharge (aOR:0.77; 95% CI: 0.69-0.87; p<0.01). There was no difference in the odds of 30-day or 180-day all-cause, AF-related, or atrial flutter-related readmissions in patients with RMVD vs. no RMVD (Figure 1). Conclusion: In conclusion, patients with RMVD undergoing AF ablation have higher odds of periprocedural cardiovascular complications with similar odds of 30-day and 180-day all-cause and AF-related readmissions

Introduction: There is limited data on how psychosocial risk factors (PSRFs) affect the outcomes of patients undergoing atrial fibrillation (AF) ablation. Hypothesis: We hypothesized that the presence of PSRFs affects the outcomes of AF ablation and tested this hypothesis using a nationally representative sample of the US population. Methods: The National Readmissions Database (NRD) was analyzed from 2016-2019 to identify patients ≥ 18 years old undergoing AF ablation. Patients were divided into two cohorts based on the presence or absence of ≥1 PSRF. PSRFs were divided into 5 domains including limited cognitive understanding, substance use, psychiatric disease, low socioeconomic status, and uninsured status. A multivariable logistic regression model was utilized to adjust for confounders. Results: Our cohort included 50,623 AF ablation procedures, of which 21,363 (42.2%) had ≥ 1 PSRF. On multivariable analysis, the presence of ≥ 1 PSRF was associated with higher odds of cardiovascular complications (adjusted odds ratio [aOR] 1.11; 95% confidence interval [CI]: 1.02-1.22; p=0.02), peripheral vascular complications (aOR:1.18; 95% CI: 1.01-1.38; p=0.04), pulmonary complications (aOR:1.16; 95% CI: 1.05-1.29; p<0.01) and neurological complications (aOR:1.42; 95% CI: 1.12-1.78; p<0.01), along with higher odds of 30-day all-cause readmissions (aOR:1.30; 95% CI: 1.19-1.43; p<0.01) and atrial fibrillation/flutter related readmissions (aOR:1.27; 95% CI: 1.08-1.50; p<0.01), 90-day all-cause readmissions (aOR:1.30; 95% CI: 1.20-1.40; p<0.01) and atrial fibrillation/flutter related readmissions (aOR:1.22; 95% CI: 1.06-1.41; p<0.01), and 180-day all-cause readmissions (aOR:1.35; 95% CI: 1.24-1.45; p<0.01) (Figure 1). Conclusion: In conclusion, our data suggest an association between PSRFs and worse in-hospital outcomes along with increased all-cause and arrhythmia-related readmissions in patients undergoing AF ablation.

AbstractThe association of psychosocial risk factors with cardiovascular disease is well‐established, and there is a growing recognition of their influence on atrial fibrillation (AF) . A recent National Heart, Lung, and Blood Institute workshop called for transforming AF research to integrate social determinants of health. There is limited data examining the impact of psychosocial risk factors (PSRFs) on outcomes in patients with an established diagnosis of AF. Catheter ablation for AF has been shown to improve arrhythmia burden and quality of life compared with medical treatment alone. It is unknown how PSRFs affect clinical outcomes in patients undergoing AF ablation. It is important to understand this relationship, especially given the increasing adoption of catheter ablation in clinical practice.

Abstract Aims Haematopoietic stem cell transplantation (HSCT) is a potentially curative therapy for several malignant and non-malignant haematologic conditions. Patients undergoing HSCT are at an increased risk of developing atrial fibrillation (AF). We hypothesized that a diagnosis of AF would be associated with poor outcomes in patients undergoing HSCT. Methods and results The National Inpatient Sample (2016–19) was queried with ICD-10 codes to identify patients aged &gt;50 years undergoing HSCT. Clinical outcomes were compared between patients with and without AF. A multivariable regression model adjusting for demographics and comorbidities was used to calculate the adjusted odds ratio (aOR) and regression coefficients with corresponding 95% confidence intervals and P-values. A total of 50 570 weighted hospitalizations for HSCT were identified, out of which 5820 (11.5%) had AF. Atrial fibrillation was found to be independently associated with higher inpatient mortality (aOR 2.75; 1.9–3.98; P &lt; 0.001), cardiac arrest (aOR 2.86; 1.55–5.26; P = 0.001), acute kidney injury (aOR 1.89; 1.6–2.23; P &lt; 0.001), acute heart failure exacerbation (aOR 5.01; 3.54–7.1; P &lt; 0.001), cardiogenic shock (aOR 7.73; 3.17–18.8; P &lt; 0.001), and acute respiratory failure (aOR 3.24; 2.56–4.1; P &lt; 0.001) as well as higher mean length of stay (LOS) (+2.67; 1.79–3.55; P &lt; 0.001) and cost of care (+67 529; 36 630–98 427; P &lt; 0.001). Conclusion Among patients undergoing HSCT, AF was independently associated with poor in-hospital outcomes, higher LOS, and cost of care.
