Introduction The effect of major depressive disorder (MDD) on heart failure types is unclear. We aimed to assess the association of depression in heart failure with preserved ejection fraction (HFpEF) and heart failure with reduced ejection fraction (HFrEF) readmissions using the Nationwide Readmission Database (NRD) 2018.  Methods  We identified hospitalizations with a primary discharge diagnosis of HFrEF and HFpEF by appropriate ICD-10-CM codes. We acquired mortality and readmission data with and without MDD at 30 days. We used multivariate logistic regression analysis to estimate the adjusted odds ratio (aOR). Results  Among 102,997 patients admitted with heart failure as a primary diagnosis, 11% had MDD. We found a similar prevalence of HFpEF with MDD compared to HFrEF at 13.9% and 10%, respectively. Both HFrEF and HFpEF patients with MDD had similar combined outcomes of 30-day mortality and rehospitalization compared to patients without MDD with aOR 0.94 (95% CI: 0.85-1.04) and 0.93 (95% CI: 0.81-1.07), respectively. Both types of HF with MDD were associated with lesser mortality. Conclusion MDD was associated with similar combined 30-day mortality and readmissions for both HFrEF and HFpEF. However, MDD was associated with decreased 30-day mortality in both groups of heart failure (HF) patients. Further studies with robust medications and treatment data are needed to verify the results of our study.
