title: [In-hospital prognosis of right ventricular myocardial infarction].
abstract: OBJECTIVE
  To identify prognostic risk factors for in-hospital outcome of right ventricular myocardial infarction (RVI).
  
  
  METHODS
  A retrospective study of 20 patients admitted with acute myocardial infarction with a RVI defined by ST segment elevation > or = 1 mm in V3R and V4R leads.
  
  
  RESULTS
  The mean age was 62 years. RVI was associated with an inferior myocardial infarction in 18 patients. Half of the patients had hemodynamic complication on admission (cardiogenic shock in 4 cases, right ventricular failure in 6 cases) and third degree atrio-ventricular block was present in 5 patients. Sixteen patients (80%) received thrombolysis and 3 went to an emergency angioplasty. The in-hospital mortality was 25% caused by a cardiogenic shock in 4 patients and a ventricular fibrillation in 1 patient. Statistic analysis showed that cardiogenic shock on admission, the absence of thrombolytic therapy and the low ejection fraction of the left ventricle were associated with a high in-hospital mortality (p = 0.004, p = 0.03, p = 0.03 respectively).
  
  
  CONCLUSIONS
  In-hospital outcome of RVI is characterized by hemodynamic complications leading to a high incidence of mortality. Thus RVI must be diagnosed quickly and maximal therapeutic efforts must be done to procure the opening of the occluded coronary artery.
