ABSTRACT
OBJECTIVE: The aim of this study is to show that differences of mortality, in acute myocardial infarction, observed between hospitals are not necessarily linked to a bad application of guidelines but can be linked to differences in the risk profile of the populations. METHODS: Two populations admitted for ST and non-ST elevation myocardial infarction in the same region in 2006 were compared: the population of Chalon-sur-Saône's hospital with a standard population from the observatoire des Infarctus de Côte d'Or (RICO). The risk profile of the two populations has been realised with the risk scores GRACE, EMMACE and the Simple Risk Index (SRI). RESULTS: The three scores are applicable for our populations according to the "C statistic". Moreover, there is a significant difference of in-hospital mortality between Chalon-sur-Saône and RICO. But, the population of Chalon-sur-Saône presents a higher risk. Finally, in-hospital rate mortality expected by the three scores is not different from the actual mortality. CONCLUSION: GRACE, EMMACE and SRI are valid scores for the comparison of risk profile of populations in acute myocardial infarction. Comparisons between hospitals are only possible after risk adjustment of the populations.

INTRODUCTION: Pacemaker implantation is a usual technique in cardiology which may be followed by acute pleural effusion and delayed unusual pericarditis. CASE REPORT: We reported the case of a 67 year-old man hospitalized for faintness. Rhythmical auricular disease was diagnosed and pacemaker was implanted without immediate complication. Though pericarditis with tamponade at the day 21 will require emergency pericardiotomy surgery. A recurrent pericarditis at day 45 was treated with anti-inflammatory drugs without relapse at the end of the treatment. DISCUSSION: Repeated delayed pericarditis after pacemaker surgery may be compared to the Dressler syndrome which occurs after myocardial infarction.
