BackgroundTo investigate the association between hyperuricemia and major adverse cardiac events (MACE) in patients with acute myocardial infarction (AMI).MethodsConsecutive patients admitted with AMI to the Coronary Care Unit at R. K. Khan Hospital (Durban, South Africa) between the years 2006 and 2014 were included. Demographic data, including clinical and biochemical information stored in an electronic database, were obtained from all patients.ResultsA total of 2683 patients were studied, of whom 65% were males. The mean age of the participants was 57.1 ± 11.5 years, with 79% presenting with ST elevation myocardial infarction. Sixty-one percent were smokers, 59% had diabetes mellitus, 52% had hypertension, and 58% presented with a family history of premature coronary artery disease. Twenty-six percent (n = 690) had hyperuricemia, were older (59 ± 12.1 vs. 56.5 ± 11.2 years) and more likely to present with hypertension (P ConclusionsHyperuricemia is significantly associated with hypertension, renal dysfunction, MACE, and independently confers a higher risk of mortality in patients with AMI. Significant heterogeneity was found by gender for risk factors and clinical events in individuals with hyperuricemia. A graded increase was demonstrated in the risk of MACE, particularly for cardiac failure and death, by increasing tertiles of hyperuricemia.
