Abstract Body (Do not enter title and authors here): Introduction:
Several studies have linked mental health disorders and substance abuse as risk factors for stress cardiomyopathy (SC). However, the true burden of these disorders amongst patients with stress cardiomyopathy remains unknown.
Methods:
We used the 2016-2020 National Inpatient Sample database to identify hospitalizations for SC who underwent diagnostic catheterization. We assessed the proportion of patients diagnosed with a substance abuse or mental health disorder. Subsequently, the association of these disorders in SC compared to patients admitted for myocardial infarction (MI) was assessed using the chi-square test.

Results:
From 2016 to 2020, there were 33,075 hospitalizations for stress cardiomyopathy who were diagnosed by cardiac catheterization. Of these patients, 5,920 (17.9 %) had depression, 8,500 (25.7 %) had anxiety, 1058 (3.2 %) had severe stress reactions, and 16,372 (49.5 %) were diagnosed with a mental health disorder. 9,955 (30.1 %) were smokers, 5,358 (16.2%) abused hallucinogens, 5,457 (16.5 %) abused cocaine, 5,457 (16.5%) abused sedatives, 6,019 (18.2 %) abused cannabis, 5,920 (17.9%) abused opioids, 6,416 (19.4 %) abused alcohol. Subsequently, the association of stress cardiomyopathy with mental and substance abuse disorder was compared with patients admitted with myocardial infarction See Table 1.
Conclusion:
Mental health and substance abuse disorders are common in patients diagnosed with SC. These disorders are more commonly present in SC compared to MI. Further research is needed to assess the significance of these findings.
