BACKGROUND/PURPOSE: Takotsubo Cardiomyopathy (TCM) or stress-induced cardiomyopathy is characterized by transient wall motion abnormalities often preceded by physical or emotional stress. Various baseline medical comorbidities were associated with worse outcomes theoretically due to their effect on chronic stress exposure. The effect of concurrent Human Immunodeficiency Virus (HIV) infection on outcomes of TCM has not been well established. CONCLUSION: TCM patient with concurrent HIV had numerically worse outcomes. After adjusting for potential confounders, the statistical significance no longer existed. Suggesting that statistical difference was primarily driven by difference in baseline sociodemographic parameters and coexisting comorbidities. Copyright (c) 2021. Published by Elsevier Inc. METHODS/MATERIAL: We conducted a US-wide analysis of TCM hospitalizations from 2006 to 2014 by querying the National Inpatient Sample database for the International Classification of Diseases-ninth Revision TCM code, baseline characteristics, and inpatient outcomes. TCM patients with HIV were compared to TCM patients without HIV. Multivariate regression models were constructed to account for potential confounders. RESULTS: We identified 123,050 patients hospitalized with TCM, of those patients 304 had positive HIV status. In an unadjusted analysis, in-hospital outcomes were worse in TCM patients with HIV infection in terms of development of acute kidney injury (16.8% vs 33.3%, P-value 0.002), use of invasive mechanical ventilation (18.3% vs 34.5%, P-value 0.003), and mortality (5.3% vs 17.1%, P-value <0.0001). After adjusting for age, gender, and comorbidities there was no significant difference in the captured outcomes.
