RESUMEN
OBJECTIVE: To estimate the prevalence of ischemic heart disease and associated factors in patients with rheumatoid arthritis. METHODS: A cross-sectional study using the American College of Rheumatology diagnostic criteria in order to select patients seen at primary or secondary health care units in Blumenau, Santa Catarina, Southern Brazil, in 2014. The presence of ischemic heart disease was defined as an acute myocardial infarction with percutaneous coronary intervention or coronary artery bypass graft surgery that has occurred after diagnosis. Fischer's exact test, Wald's linear trend test, and multivariate logistic regression analysis were used to test the associations. RESULTS: Among 296 patients (83.1% female) with a mean age of 56.6 years and a mean rheumatoid arthritis duration of 11.3 years, 13 reported having acute myocardial infarction requiring a percutaneous or surgical reperfusion procedure, a prevalence of 4.4% (95% CI 2.0-6.7). Diabetes Mellitus (odds ratio [OR] 4.9 [95% CI 1.6-13.8]) and disease duration >10 years (OR 8.2 [95% CI 1.8-39.7]) were the only factors associated with an ischemic disease that remained in the final model, after the multivariate analysis. CONCLUSION: The prevalence of acute myocardial infarction was similar to that observed in other studies. Among the traditional risk factors, Diabetes Mellitus, and among the factors related to rheumatoid arthritis, disease duration, were the variables associated with comorbidity.

Resumo Objetivo: Estimar a prevalência da doença isquêmica cardíaca e os fatores associados em pacientes com artrite reumatoide. Métodos: Estudo transversal que usou o critério diagnóstico do Colégio Americano de Reumatologia para selecionar pacientes atendidos nas unidades de saúde da atenção primária ou secundária em Blumenau, Santa Catarina, sul do Brasil, em 2014. A presença de doença cardíaca isquêmica foi definida com infarto agudo do miocárdio com intervenção coronariana percutânea ou cirurgia de revascularização do miocárdio que tenha ocorrido depois do diagnóstico. Para testar as associações usou-se o teste exato de Fischer, o teste de tendência linear de Wald e a análise de regressão logística multivariada. Resultados: Entre 296 pacientes, 83,1% de mulheres, com média de 56,6 anos, tempo médio de artrite reumatoide de 11,3 anos, 13 relatam ter tido infarto agudo do miocárdio que necessitou de procedimento de reperfusão percutânea ou cirúrgica, prevalência de 4,4% (IC 95% 2,0-6,7). O diabetes melittus (razão de chance de 4,9 [IC 95% 1,6-13,8]) e o tempo de doença maior do que 10 anos (razão de chance de 8,2 [IC 95% 1,8-39,7]) foram os únicos fatores associados com a doença isquêmica que permaneceram no modelo final após análise multivariada. Conclusão: A prevalência de infarto agudo do miocárdio foi semelhante com a observada em outros estudos. Entre os fatores de risco tradicionais e entre os fatores relacionados à artrite reumatoide, o diabetes melittus e o tempo de doença foram as variáveis associadas à comorbidade
