Right ventricular infarction (RVI) is most commonly associated with inferior wall infarction (20-50% of cases). Clinical presentation of RVI may vary.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.The analysis involved 181 consecutive patients (pts) with inferior wall myocardial infarction hospitalised between 1 July 2000 and 1 July 2002.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 aged70 years compared to patients below 70 years (38.5% vs 7.7%, p=0.017).RVI is associated with worse prognosis and increased number of in-hospital complications. Older patients aged70 years have definitely poorer prognosis. Thrombolytic therapy in a subgroup of older patients with RVI remains ineffective.
