Abstract：Objective To observe the long-term safety and efficacy of drug eluting stent ( DES) implantation reste-nosis ( ISR) patients're-implementation of DES implantation .Methods Selected DES implantation in patients with coronary heart disease , coronary angiography examination confirmed the occurrence of restenosis ( ISR≥50%) , and once again in the DES intervention ISR operation successful patients .985 cases of DES ISR patients according to narrow type were divided into localized stenosis group with 130 cases (13.2%), diffuse stenosis group with 699 cases (71.0%), occlusive stenosis group with 156 cases (15.8%).Long term follow-up observation of efficacy and safety in the 3 groups (6 months, 12 months). Results After 6 months of follow-up, localized stenosis group with major adverse cardiovascular events ( MACE) occurred in 3.85%(5/130);in diffuse stenosis group, the incidence of MACE was 2.72%(19/699);in occlusion stenosis group, the incidence of MACE was 3.21%(5/156), no statistically significant of 6 month follow-up were found among 3 groups ( P >0.05).After 12 months of follow-up, localized stenosis groups'incidence of MACE was 13.08%(17/130);in diffuse steno-sis group, the incidence of MACE was 9.16%(64/699); in occlusion stenosis group , the incidence of MACE was 9.62%(15/156), the follow-up results of 3 groups of 12 months had no statistical difference significance ( P >0.05).Conclusion It demonstrated that the re-implementation DES implantation was an effective alternative for treatment of DES ISR .
