p-value of group differences from Student’s t-test for continuous variables and chi-square for categorical variables.
AA – African American
LVEF – Left ventricular ejection fraction
BMI – Body mass index
CCI – Charlson Comorbidity Index
HS – High school
HFpEF – Heart failure with preserved ejection fraction
HFrEF – Heart failure with reduced ejection fraction
