National trends in racial disparities among hospitalizations and outcomes in patients with dilated cardiomyopathy

Cardiomyopathies are diseases that affect the cardiac musculature resulting in dilated, hypertrophic, or restrictive patterns.1 DCM refers to left or biventricular dilatation leading to systolic dysfunction in the presence of patent coronary vasculature.1 DCM is most common in patients 40 to 59 years of age, however, can occur at any age and remains one of commonest indications for heart transplant.2 DCM may be idiopathic, familial/genetic (20-30%), viral, and/or immune.3 Advances have been made in the management of patients with DCM during recent decades.4 There remains a paucity of studies looking into the mortality, racial disparities and associated adverse cardiovascular events associated with DCM. We aim to elucidate the recent trends in DCM hospitalizations across the United States (US).
