Allopurinol in Acute Coronary Syndrome

• Status: Not yet recruiting
• Trial end date: 2021-12-31
• Target enrollment: 0
• Participant gender: All

Summary

The pathogenesis of coronary heart disease is closely related to inflammation. IL-1 beta is an effective target for anti-inflammatory treatment of coronary heart disease. Allopurinol is a drug used for treating hyperuricemia and gout for many years. Recently, allopurinol has been proved to inhibit the production of NLRP3 in monocytes and reduce the level of IL-1beta, resulting in the decrease of TNF-alpha, IL-6 and CRP. Thus, in this study, the investigators aim to evaluate the efficacy and safety of allopurinol sustained-release capsules on improving the stability of coronary plaque in patients with acute coronary syndrome treated by conventional standardized therapy by the single-center, prospective, randomized, double-blind and controlled methods, which would provide new strategies for the treatment of coronary heart disease.
