Association of chronic kidney disease (CKD) and end-stage renal disease (ESRD) with procedural complications and in-hospital outcomes from left atrial appendage occlusion (LAAO) device implantation in elderly (>80 yrs) patients with atrial fibrillation (AF)
Abstract Body (Do not enter title and authors here):
Background: LAAO has been used as an alternative strategy for stroke prevention in selected patients with AF, however there is very limited data about the outcomes in elderly patients with kidney disease.
Methods: The National Inpatient Sample was queried for LAAO in the US between 2015–2020. Hospital outcomes were assessed for elderly patients undergoing LAAO in three cohorts; no CKD, CKD and ESRD.
Results: A total of 31,360 elderly patients undergoing LAAO were identified in the study period; 23,250 (74.1%) had no CKD, 7,610 (24.2%) had CKD, and 500 (1.5%) had ESRD. CKD and ESRD were independently associated with higher odds of in-hospital mortality [aOR 3.06, 95 % CI (1.805-5.207), p <0.001)]& [ aOR 9.69 ,95% CI (3.52-26.64), p <0.001], cardiovascular complications [ aOR 1.43 ,95% CI (1.208-1.696), p <0.001] &[ aOR 3.41 ,95% CI (2.12-5.48), p <0.001], p <0.001], neurological complications [aOR 1.2 ,95% CI (1.05-1.36), p=0.006] &[aOR 1.58 ,95% CI (1.07-2.33), p=0.019], gastrointestinal and hematological complications [aOR 1.22 ,95% CI (1.06-1.39), p=0.003] &[ aOR 1.71 ,95% CI (1.16-2.52), p <0.001] respectively when compared to patients with no CKD. CKD was independently associated with higher odds of renal complications compared to patients with no CKD [aOR 5.34 ,95% CI (4.532-6.303), p <0.001]. In comparison to patients with ESRD, patients with CKD had significantly higher odds of renal complications [aOR 8.01 ,95% CI (3.28-19.57), p <0.001] with no significant difference in the odds of in-hospital mortality [aOR 0.4 ,95% CI (0.14-1.12), p=0.08]. In terms of resource utilization, length of stay didn’t differ with different kidney functions (1(1-1) for the three cohorts). However the ESRD cohort had the highest hospitalization costs compared to the CKD and no CKD cohorts ($26.113 ($19.728 -$34.362) vs. $25.799 ($20.231-$32.943) vs. $24.894 ($19.641-$31.373), p <0.001).
Conclusion: The prevalence of CKD and ESRD was around 25.7% in elderly patients with AF undergoing LAOO. CKD and ESRD were independently associated with higher odds of in-hospital mortality compared to patients with no CKD while CKD was independently associated with higher odds of renal complications after LAAO.
