Abstract

BACKGROUND: Takotsubo cardiomyopathy (TCM), defined by transient left ventricular dysfunction, is commonly triggered by acute emotional/physical stress. It is recognized as a cause of acute coronary syndrome, particularly in the elderly population, as they are vulnerable due to multiple comorbidities, including frailty, a condition marked by reduced functional reserve and increased susceptibility to stressors.

METHODS: A retrospective analysis of the National Inpatient Sample (2016-2021) was performed to identify patients aged 65 and older hospitalized with TCM using ICD-10-CM codes. Patients were classified based on frailty, defined by Johns Hopkins ACG frailty-defining diagnoses. Multivariable mixed-effects logistic regression was used to identify independent predictors of in-hospital outcomes and compare the groups. Propensity score matching was applied to 736 pairs to control for confounders and assess outcomes.

RESULTS: Frail patients had significantly high in-patient mortality (5.71

CONCLUSION: Frailty is associated with an increased in-hospital mortality among elderly patients with TCM. Understanding the importance of frailty in elderly population with TCM helps us in optimizing management strategies and improving patient outcomes.
