Heart failure & cardiomyopathies
Social Determinants of Health and Clinical Outcomes in Hypertrophic Cardiomyopathy
Authors' conclusion
In this multicenter cohort study, residing in an area with lower median household income or worse SDI were each independently associated with adverse clinical outcomes in patients with HCM.
