Socioeconomic Status and Outcomes in Heart Failure With Reduced Ejection Fraction From Asia

Little is known regarding the impact of socioeconomic factors on the use of evidence-based therapies and outcomes in patients with heart failure with reduced ejection fraction across Asia. We investigated the association of both patient-level (household income, education levels) and country-level (r...

description Little is known regarding the impact of socioeconomic factors on the use of evidence-based therapies and outcomes in patients with heart failure with reduced ejection fraction across Asia. We investigated the association of both patient-level (household income, education levels) and country-level (regional income level by World Bank classification, income disparity by Gini index) socioeconomic indicators on use of guideline-directed therapy and clinical outcomes (composite of 1-year mortality or HF hospitalization, quality of life) in the prospective multinational ASIAN-HF study (Asian Sudden Cardiac Death in Heart Failure). Among 4540 patients (mean age: 60±13 years, 23% women) with heart failure with reduced ejection fraction, 39% lived in low-income regions; 34% in regions with high-income disparity (Gini ≥42.8%); 64.4% had low monthly household income (

The largest disparity in treatment across regional income levels pertained to β-blocker and device therapies, with patients from low-income regions being less likely to receive these treatments compared with those from high-income regions and even greater disparity among patients with lower education status and lower household income within each regional income strata. Higher country- and patient-level socioeconomic indicators related to higher quality of life scores and lower risk of the primary composite outcome. Notably, we found a significant interaction between regional income level and both household income and education status ( &lt;0.001 for both), where the association of low household income and low education status with poor outcomes was more pronounced in high-income compared with lower income regions. These findings highlight the importance of socioeconomic determinants among patients with heart failure in Asia and suggest that attention should be paid to address disparities in access to care among the poor and less educated, including those from wealthy regions.
