INTRODUCTION: Right ventricular infarction (RVI) is most commonly associated with inferior wall infarction (20-50% of cases). Clinical presentation of RVI may vary. AIM: Assessment of outcome and clinical course of myocardial infarction in patients with inferior wall myocardial infarction with or without RVI. Additionally, risk stratification was attempted in the above-mentioned groups of patients. METHODS: The analysis involved 181 consecutive patients (pts) with inferior wall myocardial infarction hospitalised between 1 July 2000 and 1 July 2002. RESULTS: Nineteen in-hospital deaths were noted in the study group (mortality 10.5%), reinfarction occurred in 6 (3.3%) pts, ischaemic stroke in 1 (0.6%) patient, and 2 (1.1%) pts had transient ischaemic attack. Cardiogenic shock occurred in 20 (11.0%) pts , ventricular fibrillation in 15 (8.3%) pts, and pulmonary oedema in 9 (4.9%) pts. In the subgroup of 161 pts without cardiogenic shock 8 (4.9%) pts died. Thrombolytic therapy was administered in 96 (53%) subjects. Isolated inferior wall myocardial infarction was diagnosed in 94 (51.9%) of 181 pts and RVI in 65 (35.9%) pts. Mortality rate in the RVI group was significantly higher than in inferior wall myocardial infarction without RVI and was 18.5% vs 2.12% (p=0.0003), respectively (excluding patients with cardiogenic shock: 11.1% vs 1.2%, respectively; p=0.016). In patients with RVI aged above 70 years, the mortality rate was significantly higher than in younger patients (32% vs 10%, p=0.002). In a subgroup with RVI treated with thrombolysis mortality was considerably higher in subjects aged >70 years compared to patients below 70 years (38.5% vs 7.7%, p=0.017). CONCLUSIONS: RVI is associated with worse prognosis and increased number of in-hospital complications. Older patients aged >70 years have definitely poorer prognosis. Thrombolytic therapy in a subgroup of older patients with RVI remains ineffective.
