OBJECTIVE: Heart failure (HF) exerts deleterious effects on the gastrointestinal tract and the gut microbiome, yet its impact on inflammatory bowel disease (IBD) is unknown. This study was performed to evaluate the impact of HF on disease course and outcomes in patients with IBD.

METHODS: Using a large institutional database, we identified patients aged 18-65 years diagnosed with IBD and incident HF (IBD-HF), IBD without HF (IBD), and HF without IBD (HF). Patients were followed longitudinally, and IBD-related outcomes were compared between the IBD-HF and IBD cohorts using multivariable cox regression. General clinical outcomes were compared between all three cohorts using Kaplan-Meier survival analysis.

RESULTS: A total of 271, 2449, and 20,444 patients were included in the IBD-HF, IBD, and HF cohorts. Compared with IBD, IBD-HF had significantly higher risk of IBD-related hospitalization [hazard ratio (HR): 1.42; (95% confidence interval, CI: 1.2-1.69)], flare [HR 1.32 (1.09-1.58)], complication [HR 1.7 (1.33-2.17)], pancolitis [HR 1.55 (1.04-2.3)], and escalation to nonbiologic therapy. No significant difference was observed in the incidence of IBD-related surgery or Clostridium difficile infection. New biologic use was less frequent in IBD-HF [HR 0.52 (0.36-0.77)]. IBD-HF, compared with the other two groups, had reduced event-free survival for all-cause hospitalization (P < 0.001), emergency department visits (P = 001), and venous thromboembolism (P < 0.05). Mortality risk in IBD-HF was elevated compared to IBD but was similar to that within HF cohort.

CONCLUSION: Incident HF in patients with IBD is a predictor of adverse IBD-related and overall clinical outcomes.
