Clinical analysis of coronary-stent implantation(45cases)

Objective To evaluate the results and benefits of stenting implanation in coronary artery disease patients.Methods From May 1995 to October 1998,49 introcoronary stents were implanted on 45 patients,including 14 cases with acute myocardial infarction.There were 41 male and 4 female.They ranged in age from 41 to 70 years(mean 55.8 years).There were 5 simpal lesions and 44 complex .Indications were:de novo in 14, suboptimal in 14, bail out in 17.Results The procedure success rate was 100% .No acute or subacute intro stent thrombosis and severe bleeding was observed in a total of 49 stents.5 cases were followed up by coronory angiography(CAG) for 104 d on the average.Restenosis was found in one case(20%).Percutaneous transluminal coronary angioplasty once again(PTCA) was effective for this one of stenting postprocedural restenosis.Conclusion Coronary stent is a safe and efficient interventional procedure.In additionwith the recent advances in technique,using high implantation pressure and combined of anticoagulant therapy,all these advances have resulted extended indications and reduced complications.But the long term benifit remains to be determined.
