Chronic inflammation associated with hyperuricaemia and urate deposition may contribute to an increased risk of developing cardiovascular (CV) events (CVE) in patients with gout. The aim of this study was to explore whether urate deposition on dual-energy CT (DECT) present at the diagnosis of gout is associated with a history of CVE.Patients from a study on clinical value of DECT with mono or oligoarthritis who had gout according the 2015 EULAR/ACR classification criteria were included in this cross-sectional study. Urate volume on DECT was calculated. Patients underwent a structured CV consultation, including assessment of CVE-history and of CV risk factors, scored with the Dutch risk prediction SCORE and the Framingham score. The data were analysed using logistic regression analyses.Sixty-eight patients were included. In the multivariable model, -next to significant associations of age (OR per year 1.1, 95% CI 1.04 to 1.02, p=0.02), HDLc per mmol/l (OR 0.04, 95% CI 0.002 to 0.8, p=0.03), and diabetes yes/no (OR 4, 95% CI 0.8 to 20.9, p=0.09)-, urate volumes at ankles/feet on DECT in the third and fourth quartile with first quartile as reference showed a trend of association (OR 4.8, 95% CI 0.6 to 42, p=0.1 and 6.4, 0.7 to 63, 0.1, respectively) with past CVE events (yes/ no). This association could be bidirectional. Almost two-third of newly classified gout patients had a high or very high CV risk.CVE history probably is associated with urate volumes already present at the time of diagnosis of gout. Our data corroborate the need of assessing and treating CV risk factors when diagnosing gout. |
