Comparison of Characteristics and Outcomes of Patients With Heart Failure With Preserved Ejection Fraction With Versus Without Hyperuricemia or Gout.
(Journal Article;Multicenter Study)
Hyperuricemia and gout are common in patients with heart failure (HF) and are associated with poor outcomes. Data describing hyperuricemia and gout in patients with HF with preserved ejection fraction (HFpEF) are limited. We used data from the Duke University Health System to describe characteristics of patients with HFpEF and hyperuricemia (serum uric acid >6 mg/dl) or gout (gout diagnosis or gout medication within the previous year) and to explore associations with 5-year outcomes (death and hospitalization). We identified 7,004 patients in the Duke University Health System with a known diagnosis of HFpEF who underwent transthoracic echocardiography between January 1, 2005 and December 31, 2017. A total of 1,136 (16.2%) patients with HFpEF also had hyperuricemia or gout. Patients with HFpEF and hyperuricemia or gout had a greater co-morbidity burden, more echocardiographic findings of cardiac remodeling, and higher unadjusted rates of all-cause death, all-cause hospitalization, and HF hospitalization compared with those with HFpEF without hyperuricemia or gout. After multivariable adjustment, patients with HFpEF and hyperuricemia or gout had a significantly higher rates of first all-cause hospitalization (adjusted hazard ratio 1.10 [95% confidence interval 1.02 to 1.19]; p = 0.020) and recurrent all-cause hospitalization (associated rate ratio 1.13 [95% confidence interval 1.01 to 1.25]; p = 0.026). After adjustment, no significant differences in death or HF hospitalization were observed. In conclusion, patients with HFpEF and hyperuricemia or gout were found to have a higher burden of co-morbidities and a higher rate of all-cause hospitalization, even after multivariable adjustment, compared to patients with HFpEF without hyperuricemia or gout.
