Insights
Urate-lowering therapy (ULT) significantly reduces the risk of coronary artery disease (CAD) and stroke in gout patients. ULT showed no effect on heart failure (HF) risk, but uricosuric agents demonstrated a dose-response benefit for CAD and stroke prevention.
Area of Science:
- Cardiology
- Rheumatology
- Pharmacology
Background:
- Hyperuricemia is strongly linked to cardiovascular (CV) diseases.
- Limited research exists on urate-lowering therapy (ULT) for preventing CV disease development.
- Gout patients are at increased risk for cardiovascular events.
Purpose of the Study:
- To compare the risks of incident coronary artery disease (CAD), stroke, and heart failure (HF) between ULT users and non-users in patients with gout.
- To investigate the specific effects of different ULTs on cardiovascular outcomes.
Main Methods:
- Retrospective cohort study using Taiwan's National Health Insurance Research Database (2000-2012).
- Included 4,072 gout patients, with 2,036 ULT users and 2,036 matched non-users.
- Compared incidence rates and calculated adjusted hazard ratios (aHR) for CAD, stroke, and HF.
Main Results:
- ULT users showed significantly lower risks for incident CAD (aHR: 0.7) and stroke (aHR: 0.68) compared to non-users.
- ULT had a neutral effect on the risk of incident heart failure (aHR: 0.92).
- Uricosuric agents, a type of ULT, demonstrated significant CAD and stroke prevention, with a potential dose-response trend for CAD.
Conclusions:
- Urate-lowering therapy is associated with reduced risks of incident coronary artery disease and stroke in patients with gout.
- The findings support the recommendation for gout patients to utilize ULT to mitigate their cardiovascular disease burden.
- Uricosuric agents may offer specific cardioprotective benefits.
Abstract:
Substantial evidence has demonstrated a close relationship between hyperuricemia and cardiovascular (CV) diseases, but few studies have explored the possibility of using urate-lowering therapy (ULT) to attenuate the development of CV diseases. To compare the risks of incident coronary artery disease (CAD), stroke, and heart failure (HF) between ULT users and non-users in patients with gout, we conducted a retrospective cohort study from the population-based National Health Insurance Research Database in Taiwan. In total, 4,072 patients with gout were included between 2000 and 2012. The overall incident rates of CAD, stroke, and HF were compared between 2,036 ULT users and 2,036 matched non-users. The incident rates of incident CAD were 1.3 and 1.7 per 100 person-years for ULT users and non-users. ULT users had a lower adjusted hazard ratio (aHR) for CAD [aHR: 0.7, 95% confidence interval (CI): 0.55-0.89] compared with non-users. ULT users also had a lower aHR for incident stroke (aHR: 0.68, 95% CI: 0.5-0.92) compared with non-users. ULT had a neutral effect on the risk of incident HF (aHR: 0.92, 95% CI: 0.58-1.45). Among the urate-lowering therapy, subgroup analyses indicated that uricosuric agents had a significant effect on the prevention of CAD and stroke development; and the protection against the development of CAD by uricosuric agents appeared to have a dose-response trend. Our study demonstrated that ULT associated with lower risks of incident CAD and stroke. We recommend that patients with gout receive ULT to lower the burden of CV diseases.
