Abstract:
Objective To compare the efficacy of native vessel percutaneous coronary intervention (NV-PCI) and optimal drug therapy (ODT) in patients with recurrent angina after coronary artery bypass grafting (CABG). Methods The clinical data of 142 recurrent angina pectoris after CABG patients who had underwent coronary angiography were retrospectively analyzed. Among the patients, 70 cases were treated with NV-PCI (NV-PCI group), and 72 cases were treated with ODT (ODT group). The incidence of major adverse coronary events (MACE) and left ventricular ejection fraction (LVEF) were compared between 2 groups. Results All patients were followed up for at least 1 years. There were no statistical differences in the number of bypass vessels and number of occluded vessels between ODT group and NV-PCI group: (2.5 ± 0.7) branches/case vs. (2.4 ± 0.9) branches/case and (1.4 ± 0.9) branches/case vs. (1.3 ± 0.7) branches/case, P>0.05. The incidence of MACE in NV-PCI group was significantly lower than that in ODT group: 12.9％ (9/70) vs. 22.2％ (16/72), and the LVEF was significantly higher than that in ODT group:(63.5 ± 14.0)％vs. (57.1 ± 9.0)％, and there were statistical differences (P<0.05). Conclusions Compared with the ODT, the NV-PCI has lower incidence of MACE and higher LVEF in patients with recurrent angina pectoris after CABG.
