Therefore, we quantified the comparative cardiovascular safety of NSAIDs versus colchicine among patients with gout starting allopurinol. METHODS: We conducted a sequential, propensity score-matched, new-user comparative effectiveness study using the target trial emulation framework to compare the risk of major adverse cardiovascular events (MACE; composite of myocardial infarction [MI], stroke, or cardiovascular death) among patients with gout started on allopurinol who were prescribed NSAIDs or colchicine for gout flare prophylaxis. A sensitivity analysis employed inverse probability of treatment weighting (IPTW). Secondarily, we examined the risk of MACE with colchicine or NSAIDs versus no prophylaxis. RESULTS: Among 18,120 propensity score-matched adults with gout starting allopurinol with NSAIDs or colchicine (83.5% male, mean age 60.9 years), the incidence of MACE and cardiovascular death were higher among NSAID users compared to colchicine users, with rate differences of 38.8 (95% confidence interval [CI] 15.4-62.2) and 10.9 (95% CI 0.7-21.1) per 1,000 person-years, respectively, and hazard ratios (HRs) of 1.56 (95% CI 1.11-2.17) and 2.50 (95% CI 1.14-5.26), respectively. Results were similar when IPTW was applied. Compared to no prophylaxis, NSAID use was associated with a higher risk of MACE and MI, with HRs of 1.50 (95% CI 1.17-1.91) and 1.93 (95% CI 1.35-2.75), respectively. CONCLUSION: In these target trial emulations of patients with gout starting allopurinol, NSAID prophylaxis was associated with a higher risk of MACE than colchicine or no prophylaxis, suggesting the avoidance of NSAID for gout flare prophylaxis.","journal":"Arthritis & Rheumatology","year":2025,"id":517454,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":8,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9338,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2025-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":254683,"name":"Natalie McCormick","orcid":"0000-0002-4147-8348","position":1,"is_corresponding":false},{"id":286132,"name":"Na Lu","orcid":"0000-0001-5181-7879","position":2,"is_corresponding":false},{"id":1219096,"name":"Bohang Jiang","orcid":null,"position":3,"is_corresponding":false},{"id":1384403,"name":"Kiara Tan","orcid":null,"position":4,"is_corresponding":false},{"id":1384404,"name":"Saiajay Chigurupati","orcid":null,"position":5,"is_corresponding":false},{"id":1384405,"name":"Sharan Rai","orcid":null,"position":6,"is_corresponding":false},{"id":1265954,"name":"Gregory J.
