RESUMEN
OBJECTIVE@#To compare the success rate and the complication rate of immediate percutaneous coronary intervention (PCI) and elective PCI after coronary angiography(CAG), and to estimate the clinical value of immediate PCI.@*METHODS@#One-hundred fifteen patients who underwent immediate PCI after CAG were enrolled into the immediate group, and 172 patients on whom PCI and CAG were performed on 2 days were enrolled into the elective group in Second Xiangya Hospital of Central South University during 2005. The clinical manifestations, lesion vessel characteristics, and length and diameter of stents in the 2 groups were similar. Lesion vessels were defined as Type A, B, and C according to the standard of ACC/AHA in 1988.@*RESULTS@#The success rate and the complication rate of Type A and B lesion were not significantly different in the 2 groups (P>0.05). The success rate of Type C lesion in the immediate group was lower than that in the elective group (P<0.01). The complication rate of Type C lesion in the immediate group was higher than that in the elective group (P<0.05).@*CONCLUSION@#Type A and B lesions may undergo immediate PCI, while Type C lesion is not suitable to be performed immediately PCI after CAG. Immediate PCI after CAG has some clinical value.
