0.05). Angiographically identified stent thrombosis occurred in 2 patients (0.9%) in Firebird group, 2 patients (0.9%) in Cypher group and 3 patients (1.6%) in Taxus group. Conclusion Implantation of the Firebird stent in unselected patients with coronary artery disease is safe and has shown no inferiority in one-year clinical outcomes compared to the Cypher or Taxus stents.

Objective To evaluate the efficacy and safety of percutaneous stent implantation for native aortic coarctation. Methods Five patients with native coarctation of the aorta underwent percutaneous endovascular angioplasty and stenting. Immediate and long-term outcomes were assessed in terms of blood pressure changes, procedure complications, and medications. Results Compared before and after stenting, the pressure gradient associated with the stenotic segment was decreased immediately after stenting [(73?6) mm?Hg vs (8?2) mm?Hg, P

Objective To evaluate clinical and procedural characteristics and outcomes of patients with ST-elevation myocardial infarction(STEMI) caused by drug-eluting stent(DES) thrombosis undergoing primary percutaneous coronary intervention(PCI).Methods From October 2004 to June 2007,31 patients with STEMI due to definite DES thrombosis who received primary PCI were retrospectively studied(ST group).Baseline clinical,angiographic,PCI procedural features and 1-year outcomes were recorded.Another consecutive 93 patients with STEMI due to de novo coronary thrombosis were served as control group.The primary endpoint was cumulative rate of major adverse cardiac events(MACE),including death,reoccurrence of myocardial infarction and target vessel revascularization(TVR),during hospitalization and at 1-year follow-up.Results Compared with the control group,patients in ST group were older(69.9?11.4 y and 63.7?13.6 y,P=0.01) and higher comorbidity rates of diabetes(41.9% and 22.6%,P=0.04)and previous history of myocardial infarction(29.0% and 11.8%,P=0.02).The occurrence of TIMI 3 flow immediately after primary PCI was reduced(45.2% and 92.5%,P

0.05).Conclusion Early pre-interventional tirofiban therapy for patients with acute STEMI who undergo primary PCI improves patency of infarct-related artery and tissue reperfusion,but its effects on short-term clinical outcomes are similar to routine tirofiban administration in catheter laboratory.

50%) underwent renal artery stent implantation and percutanous coronary intervention, only 10 of them with merely renoarterial stenosis undergone renal artery stent implantation. The successful rates of the procedure and complication together with the volumes of contrast media were recorded respectively. And the serum creatitine before and 12 hours after the successful procedure were also measured. Results Both rates of procedural success and complication were similar among the three groups. The serum creatitine levels, 12 hours after the procedure, showed no difference in comparing with the baseline. Conclusion Non-ionic contrast media (Iopamiro 370) could be safely used in patients with RAS.

Objective To evaluate the clinical outcomes of sirolimus-eluting stenting in patients with coronary artery disease and type 2 diabetes.Methods Among 101 patients with coronary artery disease and type 2 diabetes who underwent percutaneous coronary intervention, 67 received sirolimus-eluting stents (SES group) and 34 were treated only with bare metal stents (BMS group). Baseline clinical characteristics, procedural success rate, occurrence of cardiac events during follow-up were recorded and compared between the two groups. Results The procedural success rate was 100% in both groups. During follow-up(average one year), the SES group patients had significantly lower occurrence of cardiac events than those in the BMS group ( 7.5% vs. 32.4%, P= 0.001).Conclusions Sirolimus-eluting stent implantation for patients with coronary artery disease and type 2 diabetes is safe and can reduce major adverse cardiac events in long-term follow-up.
