*P values were obtained using one-way analysis of variance test for means and χ2 test for categorical variables.
HF, heart failure; HFpEF, heart failure with preserved ejection fraction; HFrEF, heart failure with reduced ejection fraction; pEF, preserved ejection fraction; rEF; reduced ejection fraction.
