Abstract

Background: Patients with Adrenal Insufficiency (AI) face elevated cardiovascular risks, but little remains known about arrhythmia outcomes in this context.

Method: Analyzing the 2016-2019 Nationwide Inpatient Sample, we identified cases of Atrial Fibrillation, Atrial Flutter, and paroxysmal supraventricular tachycardia (PSVT) with a secondary diagnosis of AI. Mortality was the primary outcome while vasopressors and/or mechanical ventilation use, length of stay (LOS), and total hospitalization charges (THC) constituted secondary outcomes. Multivariate linear and logistic regression models were used to adjust for confounders.

Results: Among patients with Atrial Fibrillation, Atrial Flutter, and PSVT (N=1,556,769), 0.2% had AI. AI was associated with higher mortality (adjusted OR [aOR] 2.29, p=0.001), vasopressor and/or mechanical ventilation use (aOR 2.54, p<0.001), THC ($62,347 vs. $41,627, p<0.001) and longer LOS (4.4 vs. 3.2 days, p<0.001) compared to no AI.

Conclusion: AI was associated with higher adverse outcomes in cases of Atrial Fibrillation, Atrial Flutter, and PSVT.
