Racial, Sex, and Age Disparities in Cardiomyopathy Etiology: A Social Determinant Analysis of 366 Cardiac Patients

Cardiomyopathy etiology is associated with systematic demographic patterns. African Americans are more likely to experience earlier onset and greater DCM burden, while Caucasians exhibit markedly higher HCM prevalence. Male sex is disproportionately represented in DCM and HCM. These findings are consistent with SDoH-driven inequities and underscore the need for earlier detection, equity-centered prevention, and improved access to specialized diagnostics and therapies.
