Insights
Gout patients face a higher risk of coronary heart disease (CHD). This risk is influenced by age, hypertension, hyperlipidemia, and diabetes mellitus, underscoring the link between inflammatory arthritis and cardiovascular health.
Area of Science:
- Rheumatology and Cardiology
- Epidemiology
- Public Health
Background:
- Gout is a prevalent inflammatory arthritis in adult males.
- Gout diagnosis is associated with an increased risk of coronary heart disease (CHD).
- Understanding this association is crucial for patient management and cardiovascular risk stratification.
Purpose of the Study:
- To investigate the correlation between gout and the incidence of coronary heart disease (CHD).
- To identify other risk factors associated with CHD in patients with gout.
Main Methods:
- A retrospective cohort study utilizing the Longitudinal Health Insurance Database of Taiwan.
- Inclusion of 46,140 patients diagnosed with new-onset gout between 2003 and 2010.
- Propensity score matching and Cox proportional hazard modeling to analyze CHD risk.
Main Results:
- Patients with gout exhibited a significantly higher risk of CHD (adjusted HR = 1.34, 95% CI: 1.23-1.45).
- CHD risk escalated with increasing age.
- Hypertension (adjusted HR = 1.53), diabetes mellitus (adjusted HR = 1.24), and hyperlipidemia (adjusted HR = 1.18) were significant risk factors.
Conclusions:
- A significant correlation exists between gout and coronary heart disease (CHD).
- Hypertension, hyperlipidemia, and diabetes mellitus are key influencing factors for CHD in gout patients.
- Age and gender also demonstrate associations with CHD risk.
Background:
Gout is the most common inflammatory arthritis in adult males. Patients with gout are at a higher risk of coronary heart disease (CHD). This study aimed to investigate the correlation between gout and CHD.
Methods:
This was a retrospective cohort study that used data from the Longitudinal Health Insurance Database of Taiwan. The study subjects were 46,140 patients with new-onset gout during 2003-2010. To avoid selection bias, we used propensity score matching. A Cox proportional hazard model was used to analyze differences in the risk of CHD between patients with and without gout after controlling for related variables.
Results:
The patients with gout had a higher risk of CHD than the patients without gout [adjusted hazards ratio (HR) = 1.34, 95% confidence interval (CI): 1.23-1.45]. The risk of CHD increased with older age. Other related factors for CHD included gender (female vs. male, adjusted HR = 0.86, 95% CI: 0.79-0.93), hypertension (adjusted HR = 1.53, 95% CI: 1.42-1.65), hyperlipidemia (adjusted HR = 1.18, 95% CI: 1.07-1.29), and diabetes mellitus (adjusted HR = 1.24, 95% CI: 1.13-1.36).
Conclusions:
We found correlations between gout and CHD and other influencing factors including hypertension, hyperlipidemia, and diabetes mellitus. We also found that gender and age were associated with CHD.
