Abstract
Background: Depression has been suggested to increase the risk of cardiovascular disease, but many studies assessed depression after heart disease onset. This study evaluated the association between depression and myocardial infarction (MI) using a large inpatient database.Methods: We analyzed patients from the National Inpatient Sample hospitals from 2005 to 2020, selecting those aged >30 with ICD-9 and ICD-10 codes for segment elevation (ST) elevation myocardial infarction (STEMI), non-STelevation myocardial elevation (NSTEMI) and major depression.Results: Our data included 4413,113 STEMI patients (224,430 with depression) and 10,421,346 NSTEMI patients (437,058 with depression). No significant association was found between depression and MI. For STEMI, the 2005 odds ratiowas 0.12(95% CI: 0.10-0.15, p<0.001) and the 2020 odds ratio was 0.71 (95% CI: 0.69-0.73, p<0.001). Similar patterns were observed for NSTEMI.Conclusion: Depression may not independently be a significant risk factor for MI.
