Abstract
The role of thrombolytic therapy (TT) and percutaneous coronary interventions (PCIs) in subgroups of patients with right ventricular infarction (RVI) has not been evaluated. We risk-stratified 302 patients with RVI into three subsets upon admission. Class A (n =197) comprised patients without right ventricular (RV) failure, Class B (n =69) with RV failure and Class C (n =36) with cardiogenic shock. All eligible patients in Class A or B received either PCI or TT. Patients in Class C eligible for reperfusion were treated with PCI. All patients were evaluated for in-hospital major adverse cardiac events and short-term mortality. There was a statistically significant difference in in-hospital mortality among the classes. Classes B and C were the strongest indicators of in-hospital mortality. By multivariate analysis TT or PCI did not reduce mortality in Classes A and B, but a clinically favorable trend in mortality reduction was documented: both methods decreased RV dysfunction in Class B (from 97% to 61% with TT and to 28% with PCI;P P Classification into types A, B or C allows the prediction of mortality. The use of TT or PCI suggests a clinical favorable trend in the reduction of mortality in Class A, either is beneficial in Class B for decreasing morbidity and PCI appears to be the most appropriate procedure for Class C since it reduced mortality.Keywords
