Analysis of the effect of paclitaxel-eluting stents and paclitaxel-eluting balloon in the treatment of in-stent restenosis.

To compare and analyze the effect and the safety of the paclitaxel-eluting stents and paclitaxel-eluting balloon in the treatment for in-stent rest enosis. 120 cases, who had been undergone percutaneous coronary intervention (PCI) in the Department of Cardiology of Henan Provincial People's Hospital from January 2012 to January 2014 were selected. All the patients were randomly treated with paclitaxel-eluting balloon or paclitaxel-eluting stents. The former were divided into different groups that named group A and the later group B. All the selected patients signed the informed consent on interventional therapy and be given anti-platelet drugs before operating. At the same time, they had routine examination, like chest X-ray, ultrasound, biochemical detection, Myocardial injury markers. (1) The two groups had no significant difference in the general information (P>0.05); (2) The success rate in the two groups reached 100% and (3) All the patients were visited in the 9th, 12th and 24th month to see if any of them was dead. The reexamination results in the 9th month showed that both drug-eluting balloon and drug-eluting stents were safe and effective in treating coronary artery in-stent restenosis. In addition, drug-eluting balloon was more effective than drug-eluting stents to prevent from the in-stent restenosis.
