RESUMEN
Objective To assess the clinical efficiency of percutaneous coronary intervention (PCI) on cor-onary artery disease patients with complicated lesions (CAD-CL). Methods A total of 252 patients of CAD-CL treated with PCI from August,2002 to September,2009 were enrolled in the study. Clinical data on prognosis e. g, success rate, complication occurrence and major adverse cardiac events were observed. Results Two hundred and forty-four patients with CAD-CL(including chronic obstruction, bifurcation lesion, long lesion and restenosis) were implanted stent successfully(96.83%), with no residual stenosis or residual stenosis less than 20%. There were col-lateral obstructions in 32 patients and artery secret compartment in 48 patients, and restenosis in 15 patients. One patient of acute anterior myocardial infarction complicated by cardingenic shock was in low blood pressure status after two anterior descending artery stent placement, and died after temporary pacemaker implantation and other positive rescue measures. One patient occurred subacute stent thrombosis on the third day, and was cured after occlusive vas-cular recanalization through emergency PCI. Conclusions Percutaneous coronary intervention for coronary artery disease patients with comphcated lesion is safe and effective.
