Abstract

BACKGROUND: Real-world mortality data regarding heart failure in patients with comorbid chronic kidney disease remains limited, especially following the advent of advanced heart failure therapies.

METHODS: Using the CDC WONDER database, we included patients ≥ 25 years old who died primarily from heart failure (2011-2020) with comorbid chronic kidney disease. We calculated age-adjusted mortality rates (AAMR) per 100,000 individuals. We determined the trends over time by estimating the annual percent change (APC) using the Joinpoint regression program.

RESULTS: There were 82,454 heart failure deaths with comorbid chronic kidney disease. The AAMR increased from 2.34 (95% CI, 2.28- 2.41) in 2011 to 4.79 (95% CI, 4.71- 4.88) in 2020. During the study period, Heart failure deaths among patients with comorbid chronic kidney disease increased by 149.0% compared to 59.9% in those without. Men had higher AAMR than women (3.92 [95% CI, 3.88- 3.96] vs. 2.96 [95% CI, 2.93- 2.99]). African American patients had the highest AAMR (5.85 [95% CI, 5.75- 5.96]). The Midwest region had the highest AAMR (3.83 [95% CI, 3.78- 3.89]). The AAMR was higher in the rural areas than in the urban regions (3.77 [95% CI, 3.71- 3.83] vs. 3.23 [95% CI, 3.20- 3.25]). Most patients died in hospices or nursing homes (29,000, 35.2%).

CONCLUSION: Our study showed a significant increase in heart failure AAMR in patients with comorbid chronic kidney disease in recent eras. Further effort is needed to optimize cardioprotective agents for this population and to address demographic discrepancies at the policy level.
