Incidence of thrombosis after implantation of drug-eluting stents in patients with coronary artery disease

Background Randomized clinical trials have demonstrated equivalent safety to bare-metal stents after drug-eluting stents （DES） implantation. However, the DES thrombosis in randomized trials could not be comparable to those observed in clinical practice, frequently including off-label indications. This study sought to assess the incidence of DES thrombosis after implantation of DES in patients with real world coronary artery disease （CAD） in China.
Methods From December 2001 to April 2007, 8190 consecutive patients received the treatment with DES, 5412 patients completed one year follow-up： 2210 with sirolimus-eluting stent Cypher, 1238 with paclitaxel-eluting stent Taxus and 1964 with Chinese sirolimus-eluting stent Firebird, After two years of follow-up, there were 2176 patients （1245 Cypher, 558 Taxus and 373 Firebird）. All patients were treated with aspirin and clopidogrel over at least 9 months.
Results Among 8190 patients, 17 patients had acute stent thrombosis （0.24%）： 7 in the Cypher group, 4 Taxus and 6 Firebird; 23 patients had subacute stent thrombosis： 8 Cypher, 6 Taxus and 9 Firebird. The incidence of acute and subacute thrombosis was 0.49%： 0.50% Cypher, 0.63% Taxus and 0.41% Firebird. The incidence of late thrombosis at one year followup was 0.63%： 0.63% Cypher, 0.88% Taxus and 0.46% Firebird; at two year follow-up the incidence was 0.74%： 0.72% Cypher, 0.90% Taxus and 0.54% Firebird. There was no significant difference among three groups at 1 year and 2 years follow-up.
Conclusion The first generation DES in the treatment of complex lesions are safe and effective if patients are aggressively treated with dual antiplatelet agents.

Comparison of the incidence of late stent thrombosis after implantation of different drug-eluting stents in the real world coronary heart disease patients: three-year follow-up results

Background Late stent thrombosis （LST） is still concerned by interventions cardiologists in daily clinical practice. This study aimed to compare the incidence of LST after implantation of different drug-eluting stents （DES） in coronary heart disease （CHD） patients in the real world.Methods From December 2001 to February 2009, a total of 11 875 consecutive CHD patients undergone DES implantation were enrolled in this single-center registery study. Patients with acute ST-segment elevation myocardial infarction, mixed DES implantation, restenosis lesions, and patients who could not take dual antiplatlet medication and those who were contraindicated for coronary interventional treatment were excluded. All patients were treated with completed dual antiplatelet medications for at least 9 months after DES deployment. The follow-up was completed by outpatient visits, letter correspondence, phone calls and coronary angiography. Definite LST was diagnosed auording to the Academic Research Consortium （ARC） definition.Results Cypher or Cypher Select stents were implanted in 4104 cases, Taxus or Taxus Liberty stents in 2271 cases and Firebird stents （Chinese rapamycin-eluting stents） in 5500 cases. One-year follow-up was completed in 9693 patients, including 3346 cases with Cypher or Cypher Select stents, 1529 cases with Taxus or Taxus Liberty stents and 4818 cases with Firebird stents. Two- and three-year follow-up results were obtained in 7133 and 4353 patients, respectively, including 2410 and 1760 cases with Cypher or Cypher Select stents, 1285 and 900 cases with Taxus or Taxus Liberty stents as well as 3438 and 1693 cases with Firebird stents. One-year follow-up results showed that the incidence of LST was 1.08% in patients with Cypher or Cypher Select stents, 1.24% in those with Taxus or Taxus Liberty stents and 0.71% in those with Firebird stents; there was no significant difference between those with Cypher or Cypher Select and Firebird stents, but there was significant difference between those with Taxus or Taxus Liberty and Firebird stents （P=0.044）. The incidence of LST at the 2- and 3-year follow-up was 1.33% and 1.70% in those with Cypher or Cypher Select stents, 1.40% and 1.70% in those with Taxus or Taxus Liberty stents, and 0.83% and 0.95% in those with Firebird stents, respectively. There were no significant differences among the three groups.Conclusions This study indicates that first-generation DES are acceptable to treat complex coronary lesions, and there is no significant difference of LST for three different DES.

Firebird and Cypher sirolimus-eluting stents and bare metal stents in treatment of very long coronary lesions

Background As a kind of sirolimus-eluting stent （SES） made in China, Firebird SES is more effective than bare metal stent （BMS） and not inferior to Cypher SES for short coronary lesions in terms of reduction of restenosis and revascularization. However, Firebird SES does not show any benefits in patients with a very long coronary lesion （VLCL）. The present study was undertaken to evaluate the safety and efficacy of Firebird SES for VLCL by comparison of Cypher SES and BMS. Methods In this prospective, nonrandomized and comparative study, eligible patients with de novo coronary lesion （≥ 30 mm） between January 2005 and June 2006 were allocated into Firebird SES group, Cypher SES group or BMS group. They were subjected to an angiographic follow-up of 6 months and a clinical follow-up of 12 months. The primary endpoints constitute the in-stent and in-segment restenosis rates at 6 months. The secondary endpoint was defined as a major adverse cardiovascular event （MACE） that was a 12-month combined endpoint of all-cause deaths, reinfarction or in-stent thrombosis, and target-lesion revascularization. The 12-month in-stent thrombosis was also evaluated to address the safety of Firebird SES implantation exceptionally. Results A total of 468 patients were assessed for eligibility. Of 113 patients who were finally included according to the prior inclusion and exclusion criteria, 39 （41 lesions） were treated with Firebird SES, 37 （39 lesions） with Cypher SES, and 37 （37 lesions） with BMS. There were no significant differences in the baseline characteristics between the three groups; but there were longer lesions, more frequent use of overlapping stent in the Firebird SES group and the Cypher SES group. Angiographic follow-up showed that the rates of binary stenosis were similar between the Firebird SES group and the Cypher SES group （in-segment： 14.6% vs 12.8%, relative risk （RR）1.14, P=0.81; in-stent： 9.8% vs 10.3%, RR 0.95, P=0.94）, and significantly lower than those in the B     

Sirolimus-eluting cobalt alloyed stents in treating patients with coronary artery disease: six-month angiographic and one-year clinical follow-up result A prospective, historically controlled, multi-center clinical study

Background  The emergence of drug-eluting stents (DES) has dramatically reduced the incidence of in-stent restenosis. This study was conducted to evaluate the safety and efficacy of sirolimus-eluting cobalt-chrome stents (Firebird 2) for treating patients with coronary artery disease.
Methods  Sixty-seven patients with de novo or non-stented restenostic coronary lesions were chosen to receive the Firebird 2 stent as the final treatment (Firebird 2 group). Another 49 consecutive patients were implanted with bare cobalt alloyed stents (Driver, Medtronic) within the previous six months and served as historical controls (control group). Baseline clinical characteristics, angiographic features, procedural results, 30-day, 6-month and 12-month clinical follow-up regarding the occurrence of major adverse cardiac events (MACE), as well as the primary endpoint of late lumen loss at 6-month angiographic follow-up were compared between the two groups.
Results  The demographic characteristics were similar between the two groups despite more patients in the Firebird 2 group who underwent previous percutaneous coronary intervention (22.4% vs 8.2%, P=0.0418) and who had diabetes mellitus (29.9% vs 12.2%, P=0.0253). In the Firebird 2 group, the mean diameter of the reference vessel was smaller ((2.79±0.46) mm vs (2.98±0.49) mm, P=0.0175) and more stents were implanted for each lesion (1.28±0.52 vs 1.10±0.30, P=0.0060). Other angiographic, procedural results and the device success rate were similar between the two groups. The MACE rate at 30-day and 3-month was the same, but significantly fewer MACE occurred in the Firebird 2 group at 6- and 12-month follow-up (1.5% vs 12.2% at 6 month, P=0.0168; 1.5% vs 26.5% at 12 month, P<0.0001). The primary endpoint of late lumen loss at 6-month angiographic follow-up was significantly reduced in the Firebird 2 group (in-stent: (0.05±0.09) mm vs (0.98±0.61) mm; in-segment: (0.05±0.18) mm vs (0.72±0.59) mm; P<0.0001) than the control group. One patient in the Firebird 2 group had in-segment restenosis (1.3%) while the rate in the control group (38.1%) was significantly higher, P<0.0001. Intravascular ultrasound examination was performed in 70.1% of patients in the Firebird 2 group and revealed that the percentage of volumetric obstruction was (1.26±1.05) %. No stent thrombosis was observed in either group at 12-month follow-up.
Conclusion  The Firebird 2 sirolimus-eluting cobalt alloyed stent is safe and feasible in treating patients with coronary artery disease.

     

A high maintenance dose of clopidogrel improves short-term clinical outcomes in patients with acute coronary syndrome undergoing drug-eluting stent implantation

Background Recurrent ischemic events occurred even during routine use of 75 mg clopidogrel in addition to aspirin, that indicated a potentially insufficient maintenance dosage of clopidogrel. The aim of the present study was to evaluate the short-term efficacy and safety of a 150 mg maintenance dose of clopidogrel following a 600 mg loading dose in patients with an acute coronary syndrome （ACS） undergoing drug eluting stent （DES） implantation.
Methods Between November 2005 and November 2006, a total of 813 consecutive ACS patients undergoing DES implantation were enrolled. A 600 mg loading dose was administered before percutaneous coronary intervention （PCI） and patients were randomized to receive clopidogrel 75 mg or 150 mg for 30 days in addition to 300 mg aspirin daily. Primary end points were the composite of cardiac death, non-fatal myocardial infarction （MI） and urgent target vessel revascularization （UTVR）. Secondary end points included stent thrombosis （ST）, major and minor bleeding events at 30 days. Results At a follow-up period of 30 days, 4 （1.0%） patients in the 150 mg group and 9 （2.2%） patients in the 75 mg group （P 〉0.05） reached the primary end points. There was no significant difference in the incidences of MI （0.5% vs 1.2%, P〉0.05）, UTVR （0.7% vs 2.0%, P 〉0.05）, and cardiac death （0.2% vs 0.2%, P 〉0.05） between the two groups. The incidence of ST （0 vs 1.5%, P 〈0.05） was significantly lower in the 150 mg group than that in the 75 mg group. There were no significant differences between both groups regarding the risk of major （0.2% vs 0, P 〉0.05） or minor （0.5% vs 0.2%, P 〉0.05） bleedings.
Conclusion A high clopidogrel maintenance dose of 150 mg daily following a 600 mg loading dose for the first month after PCI procedure reduces the risk of ST and appears to be safe in patients with ACS undergoing DES implantation.
