Heart failure & cardiomyopathies
Racial and ethnic disparities in longitudinal trajectories of hospitalizations in patients diagnosed with heart failure
Authors' conclusion
Non-Hispanic Black patients had early, late, and consistently high risks of hospitalization following the diagnosis of HF compared with non-Hispanic White patients. These findings have important implications for targeting interventions to reduce hospitalizations during the course of HF management.

Contributors to excess admission risk among non-Hispanic Black patients
- Diabetes, chronic kidney disease, and residence in a disadvantaged neighborhood significantly contributed
Patterns of admissions, other racial and ethnic groups vs non-Hispanic White
- No significant differences
