Abstract

Aims: Gout is associated with a significant burden of cardiovascular disease. The aim of this study was to evaluate the impact of a favorable lifestyle on incident cardiovascular events in patients with gout.

Methods: We identified 9 110 patients with gout from the UK Biobank cohort based on self-report and/or hospital diagnostic codes. Lifestyle behaviors, including smoking status, physical activity, obesity, and diet, were categorized into three patterns: favorable (3-4 healthy factors), intermediate (2 healthy factors), and unfavorable (0-1 healthy factor). The cardiovascular risk of participants with and without gout was estimated based on their serum uric acid levels and lifestyle patterns.

Results: Among 9 110 patients with gout and 457 596 participants without gout, the median follow-up duration was 8.9 years. The incidence rate of cardiovascular disease was significantly higher in the gout population than in the non-gout population (11.38 vs 5.49 per 1000 person-years). The gout population consistently exhibited a high cardiovascular risk, irrespective of uric acid levels, whereas a positive correlation was observed between uric acid levels and cardiovascular risk in the non-gout population. Adopting a favorable lifestyle pattern was associated with a lower risk of cardiovascular disease in both gout and non-gout populations. Across all categories of uric acid, a favorable lifestyle was found to reduce cardiovascular risk in patients with gout.

Conclusion: Patients with gout remain at high risk of developing cardiovascular disease despite having normal uric acid levels. Lifestyle modifications may represent an effective and cost-efficient therapeutic approach for preventing cardiovascular events in this population.
