Abstract

OBJECTIVE: Our study aimed to assess the heart failure/cardiomyopathy-related population-level mortality trends among patients with obesity in the United States and disparities across demographics.

METHODS: We queried the Centers for Disease Control and Prevention's Wide-Ranging Online Data for Epidemiologic Research database among adults aged ≥25 from 1999 to 2019. Heart failure/cardiomyopathy were listed as the main causes of death, with obesity as a contributing cause. We calculated age-adjusted mortality rates (AAMR) per 100,000 individuals and estimated the average annual percent change (AAPC). We also evaluated the social vulnerability of United States counties (2014-2018).

RESULTS: There were 29,334 deaths related to heart failure/cardiomyopathy among patients with comorbid obesity. The overall AAMR increased from 0.41 in 1999 to 0.94 in 2019, with an AAPC of 3.78 (95 % CI, 3.41-4.14). The crude mortality rate increase for heart failure/cardiomyopathy was greater in individuals with comorbid obesity than in those without. Males had a higher AAMR than females (0.78 vs 0.55). African Americans also had higher AAMR than Whites (1.35 vs 0.62). The AAMR was higher in rural areas than in urban regions (0.76 vs 0.66). The overall AAMR was higher in counties with social vulnerability index-Quartile 4 (SVI-Q4) (most vulnerable) (1.08) compared to SVI-Q1 (least vulnerable) (0.63) with a risk ratio of 1.71 (95 % CI: 1.61-1.83).

CONCLUSION: Heart failure/cardiomyopathy mortality in individuals with comorbid obesity was rising. Males, African Americans, and individuals from rural regions had higher AAMR than their counterparts.
