    Abstract:
    AIM: 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). CONCLUSION: 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.
