Understanding the Complexity of Heart Failure Risk and Treatment in Black Patients

Area of Science:

• Cardiovascular Medicine
• Health Disparities Research
• Public Health

Background:

• Significant racial disparities persist in heart failure (HF) outcomes, particularly affecting Black patients.
• Age-adjusted HF death rates are substantially higher for Black individuals, especially young adults, compared to White individuals.
• Black patients face nearly 2.5-fold higher HF hospitalization rates, incurring greater first-year costs.

Purpose of the Study:

• To review the complex factors contributing to racial disparities in HF incidence, prevalence, and severity.
• To highlight evolving knowledge impacting clinical care for HF disparities.
• To identify future research needs to improve HF outcomes in Black populations.

Main Methods:

• Review of contemporary data and literature on racial disparities in heart failure.
• Analysis of factors influencing HF outcomes across different race/ethnic groups.
• Synthesis of evidence on genetic susceptibility, social determinants of health, and implicit bias in HF.

Main Results:

• The disparity in HF hospitalization between Black and White patients has not narrowed over the past decade.
• While improving for other minorities, HF hospitalization rates remain disproportionately high for Black individuals.
• Emerging evidence points to genetic susceptibility, social determinants of health, and implicit bias as significant contributors to HF disparities.

Conclusions:

• Traditional explanations like access to care and socioeconomic status are insufficient to fully explain HF outcome disparities.
• A multifactorial approach considering genetics, social determinants, and implicit bias is crucial for addressing HF disparities.
• Targeted research and clinical strategies are needed to mitigate racial disparities in heart failure care and outcomes for Black patients.
