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.

70), hypertension and multi vessel coronary artery disease.Conclusions Selective renal angiography immediately after coronary angiography is feasible and safe, and it exerts great significance of detection of RAS.

Objective To assess the influence on

0.05)compared to bare metal stents.Conclusion Age is an important clinical factor influencing mortality rate after PCI in patients with coronary artery disease,and the use of drug-eluting stents should be the preferred for the improvement of long-term outcomes in the elderly.

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 assess

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.

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

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 study the expression of receptor for advanced glycation end products ( RAGE ) in chronic adriamycin ( ADR )-induced cardiotoxicity mice . Method A mouse model of chronic cardiotoxicity was established by intraperitoneal injection of 5 mg/kg ADR once a week for continuous 3 weeks.Mice treated with the same volume of saline were used as control group (6 mice in each group).Echocardiography and histopathological examination were used to evaluate the myocardial injury , cardiac function and ventricular remodeling .The expression of RAGE in cardiac tissues was detected by immunohistochemical staining and Western blotting .Results Echocardiography indicated that ADR-treated mice had reduced left ventricular ejection fraction , while histopathological analysis of cardiac tissues showed obvious cardiac damage . RAGE protein in cardiac tissues was highly expressed in chronic ADR-induced cardiotoxicity mice .Conclusion RAGE is highly induced and may be involved in the cardiotoxicity after ADR treatment .
