RESUMEN
A low anger control has been associated to coronary artery disease (CAD). However, there is scarce information on predictors of low anger control in those patients. All patients scheduled for elective coronary angiography at a tertiary center for cardiology in South Brazil between 11/30/2009 and 02/03/2010 were considered eligible for inclusion. The inclusion criterion was the presence of significant CAD which was defined as the presence of a stenosis >50% in at least one major epicardial artery. Clinical and sociodemographic characteristics of the patients were registered, and anger aspects were assessed by the Spielberger's Anger Expression Inventory. The anger control score was categorized into quartiles, and the lowest quartil was considered and the first quartile (Low Anger Control) was compared with the others (Proper Anger Control). The medians were compared by the POISSON regression with adjustment for single and multiple robust variances. Three hundred and six patients with 60 ± 9 years old with angiographically proven CAD were included in this study. Our results showed that the younger, diabetic and patients with a family history of CAD presented lower medians for the anger control. Body Mass Index was also correlated with anger control. In the multivariate analysis, however, only family history for coronary artery disease was an independent risk factor for a low anger control. These results provide a better understanding of the relationship between anger control and CAD, and should help to consolidate the knowledge in this field and also help to plan further studies to investigate a cause-effect relationship
