Socioeconomic disparities in the management and outcomes of acute myocardial infarction
Main finding · In-hospital mortalityResult — go to the resultOdds ratio 1.10 95% CI 1.01–1.19Authors' conclusion
Patients with a higher deprivation score were more often from an ethnic-minority background, more likely to suffer in-hospital mortality or MACE when compared with the most affluent quintile, and this relationship was stronger in ethnic minorities compared with White patients.
