Evaluation of the Society for Coronary Angiography and Interventions' lesion classification system in 14,133 patients with percutaneous coronary interventions in the current stent era.

摘要: We recently showed that the ACC/AHA coronary lesion classification could be simplified with no loss of predictive value (SCAI I = patent/non-C; SCAI II patent/C; III occluded/non-C; IV occluded/C). now test this system in a database reflecting current stent usage. Data from 14,133 patients single-native-vessel interventions recorded Society for Coronary Angiography and Interventions (SCAI) Registry July 1996 to 1999 were analyzed. Stents used 60.2% procedures. Logistic models predicting angiographic success suggested slight, clinically insignificant preference (c-statistic 0.692 vs. 0.670). Models using clinical variables predict major complications superior only classification. Lesion characteristics related outcomes primarily elective (not acute myocardial infarction) patients. In PCI device era, simpler 7 predicted interventional as well or better than requiring 26. Cathet Cardiovasc Intervent 2002;55:1–7. © 2002 Wiley-Liss, Inc.
