OBJECTIVE: To examine the long-term rates of heart failure and other adverse cardiovascular outcomes in a nationwide cohort of patients diagnosed with granulomatosis with polyangiitis (GPA) compared with the background population.

METHODS: Using Danish nationwide registries, patients with first-time diagnosed GPA were identified and matched 1:4 by age, sex, and comorbidities with subjects from background population. Outcomes were compared using Cox regression. Due to violation of the proportional hazard assumption, landmark analyses for the first year and from one year were performed.

RESULTS: Of the 1,923 patients with GPA, 1,781 patients (median age 59 years, 47.9% men) were matched with 7,124 subjects from the background population. The median follow-up was 6.4 years. The absolute 10-year risk of HF was 6.8% (95%CI, 5.5-8.2%) for GPA patients and 5.9% (5.3-6.6%) for the background population. During the first year after diagnosis, GPA was associated with a significantly higher rate of HF (HR 3.60 [95%CI, 2.28-5.67]) and other adverse outcomes, including atrial fibrillation/flutter (HR 6.50 [4.43-9.55]) and ischemic stroke (HR 3.24 [1.92-5.48]), compared with the background population. After the first year, GPA was not associated with higher rates of HF or other cardiovascular outcomes than the background population, except atrial fibrillation/flutter (HR 1.38 [1.12-1.70]).

CONCLUSION: During the first year after diagnosis, the rates of HF and other cardiovascular outcomes were higher in patients with GPA compared with the background population. However, after the first year, the rates of HF and other cardiovascular outcomes, except atrial fibrillation/flutter, were similar to those in the background population.
