目的报道无保护左主干（LMCA）远端至左回旋支（LCx）单支支架置入术的临床效果。在某些情况下，支架从LMCA到LCx单独performed.MethodsBetween 2002年4月和2011年4月，单支架与药物洗脱支架远端无保护LMCA疾病进行了584例。31例患者进行了LMCA-LCx支架，谁与其余553 LMCA-LAD支架patients.ResultsAt 3年随访，有LMCA-LCx和LMCA-LAD支架组之间的主要不良心脏事件（24.1%与19.6%; P=0.540），心脏性死亡，心肌梗死没有显着差异。观察到LMCA-LCx支架植入组中靶病变血运重建（TLR）的趋势更高。当仅考虑支架分支时，这是显著的（18.2%对3.0%; P
ObjectivesTo report the clinical outcomes of single-stenting from distal unprotected left main coronary artery (LMCA) to the left circumflex artery (LCx).BackgroundPercutaneous coronary intervention of distal LMCA is usually performed by stenting into the left anterior descending artery (LAD). In some cases, stenting from LMCA to LCx alone is performed.MethodsBetween April 2002 and April 2011, single-stenting with drug-eluting stents for distal unprotected LMCA disease was performed in 584 patients. Thirty-one patients underwent LMCA-LCx stenting, who were compared with the remaining 553 LMCA-LAD stented patients.ResultsAt 3-year follow-up, there were no significant differences between LMCA-LCx and LMCA-LAD stenting groups in major adverse cardiac events (24.1% vs. 19.6%; P=0.540), cardiac death, and myocardial infarction. A trend toward higher target lesion revascularization (TLR) in the LMCA-LCx stenting group was noted. This was significant when the stented branch was only considered (18.2% vs. 3.0%; P
