Purpose: It is not clear whether PCI contributes to improve prognoses for stable angina. The purpose of this study was to determine whether there is any difference for prognosis between triple-vessel disease (TVD) and non-TVD and whether PCI improves clinical outcomes of patients with stable angina. Method: We investigated clinical courses and major adverse cardiac events (MACE) of 200 consecutive patients treated with PCI for stable angina in our institution from 2005 to 2008. We compared event rates between TVD and non-TVD groups after PCI. Result: There was no significant difference for composite rates of all-cause deaths or non-fatal myocardial infarction between the two groups (non-TVD: 9.0%, TVD: 9.0%, p=0.9874). There was no significant difference for readmission for unstable angina between the two groups (non-TVD: 4.5%, TVD: 9.1%, p=0.3507). The target lesion revascularization rate was significantly higher in the TVD group than in the non-TVD group (non-TVD: 14.0%, TVD: 25.3%, p=0.0137). Conclusion: There was no significant difference for clinical outcomes after PCI for stable angina between non-TVD and TVD. PCI for stable angina seems to contribute to reduce acute coronary events, even in those with TVD.
