Insights
Gout patients face a higher risk of cardiovascular disease (CVD) incidence. This study highlights the need for better gout management to reduce CVD burden, especially in women and younger adults.
Area of Science:
- Cardiology
- Rheumatology
- Public Health
Background:
- Gout and cardiovascular disease (CVD) are prevalent globally.
- Limited data exist on the gout-CVD association in Chinese populations.
Purpose of the Study:
- To investigate the association between gout and incident CVD risk.
- To analyze CVD risk in a large Chinese cohort.
Main Methods:
- A register-based cohort study in Shenzhen, China (2016-2022).
- Included 230,339 gout patients and 1,055,509 matched controls.
- Used Cox regression to analyze CVD incidence (IHD, stroke, HF).
Main Results:
- Gout patients had a 27% higher risk of total CVD incidence (HR: 1.27, 95% CI: 1.24-1.29).
- Incidence rates were 9.82 per 1000 person-years for gout patients vs. 6.24 for controls.
- Women and younger adults (18-44 years) with gout showed higher relative CVD risks.
Conclusions:
- Gout is significantly associated with increased incident CVD risk.
- Effective prevention and management strategies are crucial to reduce CVD burden in gout patients.
Background:
Gout and cardiovascular disease (CVD) are globally widespread diseases, yet evidence on their association in the Chinese population remains limited. We aimed to investigate the association between gout and the incident risk of CVD in a Chinese population.
Methods:
A register-based cohort study was conducted based on a city-wide health information platform in Shenzhen, China (2016-2022). We included individuals diagnosed with gout and free of CVD at baseline, and used the propensity score to select a 5-fold number of matched controls without gout. Electronic medical records and death registration were used to identify gout patients and CVD events. Cox regression models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) between gout and the incident risk of CVD, including ischemic heart disease (IHD), stroke, and heart failure (HF).
Results:
We included 230,339 CVD-free gout patients and matched 1,055,509 controls. During a maximum follow-up of 5.7 years, a total of 5108 and 16,621 incident CVD in gout patients and the controls were recorded, with incidence rates of 9.82 and 6.24 per 1000 person-years, respectively. Compared with the controls, gout patients had a higher risk (HR: 1.27, 95% CI: 1.24 to 1.29) for the total CVD incidence. Subgroup analyses showed that women and younger patients (aged 18 to 44 years) with gout had higher relative risks of CVD than their counterparts (P for interaction ≤ 0.001).
Conclusion:
We provide evidence that gout is associated with incident CVD risk, emphasizing the need for effective prevention and management strategies to mitigate CVD burden.
