Acute gouty arthritis complicated with acute ST elevation myocardial infarction is independently associated with shortand long-term adverse non-fatal cardiac events

Large epidemiologic studies have associated gouty arthritis with the risk of coronary heart disease. However, there has been a lack of information regarding the outcomes for patients who have gout attacks during hospitalization for acute myocardial infarction. We reviewed the data of 444 consecutive patients who were admitted to our hospital between 2005 and 2008 due to acute ST elevation myocardial infarction (STEMI). The clinical outcomes were compared between patients with gout attack and those without. Of the 444, 48 patients with acute STEMI developed acute gouty arthritis during hospitalization. The multivariate analysis identified prior history of gout and estimated glomerular filtration rate as independent risk factors of gout attack for patients with acute STEMI (odds ratio (OR) 21.02, 95 % CI 2.96-149.26, p =0.002; OR 0.92, 95 % CI 0.86-0.99, p =0.035, respectively). The in-hospital mortality and duration of hospital stay did not differ significantly between the gouty group and the nongouty group (controls). During a mean follow-up of 49± 28 months, all-cause mortality and stroke were similar for both groups. Multivariate Cox regression showed that gout attack was independently associated with short- and long-term adverse non-fatal cardiac events (hazard ratio (HR) 1.88, 95% CI 1.09-3.24, p =0.024; HR 1.82, 95 % CI 1.09-3.03, p =0.022, respectively). Gout attack among patients hospitalized due to acute STEMI was independently associated with short-term and long-term rates of adverse non-fatal cardiac events.
