BACKGROUND: Several cardiotoxic substances impact heart failure incidence. The burden of comorbid tobacco or substance use disorders among heart failure patients is under-characterized. We describe the burden of tobacco and substance use disorders among hospitalized heart failure patients in the United States. METHODS: We calculated the proportion of primary heart failure hospitalizations in the 2014 National Inpatient Sample with tobacco or substance use disorders accounting for demographic factors. RESULTS: Of 989,080 heart failure hospitalizations, 15.5% (n? = 152,965) had documented tobacco (n? = 119,285, 12.1%) or substance (n? = 61,510, 6.2%) use disorder. Female sex was associated with lower rates of tobacco (odds ratio [OR] 0.72; 95% confidence interval [CI], 0.70-0.74) and substance (OR 0.37; 95% CI, 0.36-0.39) use disorder. Tobacco and substance use disorder rates were highest for hospitalizations < 55years of age. Native American race was associated with increased risk of alcohol use disorder (OR 1.67; 95% CI, 1.27-2.20) and black race with alcohol (OR 1.09; 95% CI, 1.02-1.16) or drug (OR 1.63; 95% CI, 1.53-1.74) use disorder. Medicaid insurance or income in the lowest quartile were associated with increased risk of tobacco and substance use disorders. CONCLUSIONS: Tobacco and substance use disorders affect vulnerable heart failure populations, including those of male sex, younger age, lower socioeconomic status, and racial/ethnic minorities. Enhanced screening for tobacco and substance use disorders in hospitalized heart failure patients may reveal opportunities for treatment and secondary prevention.
