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.
