The indications for PCI were: (1) ST segment elevation MI (STEMI), (2) non\u2010STEMI (NSTEMI) or unstable angina, and (3) stable angina. All patients were followed up for 18 months. <jats:styled-content>Results<\/jats:styled-content>: A total of 344 patients were treated with LM PCI (STEMI: 71, NSTEMI\/unstable angina: 157, and stable angina: 116). In STEMI patients, the median logistic EuroSCORE was 22.5 (interquartile range 12.5\u201339.5), in non\u2010STEMI (NSTEMI)\/unstable angina patients 13.8 (4.8\u201323.9), and in stable angina patients 4.8 (2.2\u201310.4). Mortality after 18 months 38.0, 18.5, and 11.2% (<jats:italic>P<\/jats:italic> &lt; 0.001) in patients with STEMI, NSTEMI\/unstable angina, and stable angina, respectively. MI after 18 months was 9.9, 6.4, and 6.0% (<jats:italic>P<\/jats:italic> = ns), respectively. Four subacute and one late definite stent thrombosis were seen. TLR occurred in 5.6, 4.5, and 6.9% (<jats:italic>P<\/jats:italic> = ns) of patients, respectively. <jats:styled-content>Conclusion<\/jats:styled-content>: After PCI, patients with STEMI and LM culprit lesion have a high\u2010mortality risk, whereas long\u2010term outcome for patients with NSTEMI and stable angina pectoris is comparable with other high surgical risk patients with unprotected left main lesion. Further, TLR rates and risk of stent thrombosis were low. \u00a9 2009 Wiley\u2010Liss,
