Effect of percutaneous coronary artery interventional therapy on unprotected left main coronary artery disease / 中国基层医药

ABSTRACT

ObjectiveTo observe the effect of percutaneous coronary intervention(PCI) treatment on unprotected left main coronary artery(ULMCA) lesion.Methods40 patients with ULMCA lesions treated with PCI were followed up for 6 to 20 months,adverse cardiovascular events (MACE) occurrence were observed.ResultsAll patients treated by immediate PCI success rate was 100.0％.There were no serious complications.There were no serious adverse cardiovascular events during hospitalization.Patients were followed up 6 ～ 20 (7 ± 2) months,4 weeks after operation,acute myocardial infarction in 1 case,CAG confirmed circumflex artery open subacute stent thrombosis,re-PCI cure; postoperative mobilization of 28 patients took CAG in 6 ～ 12 months,including the opening circumflex artery stent restenosis in 3 cases,one distal left anterior descending branch of the trunk opening and then stenosis,2 cases of restenosis in patients with angina symptoms,3 patients re-line PCI,no need to CABG patients.No deaths during followup.The overall incidence of cardiovascular adverse events rate was 12.5％ (5/40),restenosis rate was 10.0％ (4/40).ConclusionThe choice of ULMCA lesions after PCI was safe and feasible,with good short and long term prognosis.
