Clinical evaluation of the dexamethasone coated stent in coronary small vessel disease / 中国介入心脏病学杂志

ABSTRACT

ObjectiveTo evaluate the clinical results of intracoronary implantation of the phosphorylcholine dexamethasone coated biodivysio small coronary stents. Methods Prospective analyses of long-term results of the phosphorylcholine dexamethasone coated biodivysio coronary stents, and their implantation performed on 82 coronary artery disease patients were conducted. We implanted 106 stents of which 54 were the phosphorylcholine dexamethasone coated biodivysio coronary stents, and 52 the phosphorylcholine coated biodivysio coronary stents. Results The success rate of the implantation of both groups was 100%. The major adverse cardiac events (MACE) of the 3-month follow-up in the phosphorylcholine dexamethasone coated biodivysio coronary stents group were 9.8%; and in the phosphorylcholine coated biodivysio coronary stents group were 22.0%. The restenosis rate of the 8-month follow-up in the phosphorylcholine dexamethasone coated biodivysio coronary stents group was 4.9%; and in the phosphorylcholine coated biodivysio coronary stents group was 23.0%. Conclusion The implantation of the phosphorylcholine dexamethasone coated biodivysio coronary stents is a safe and efficient interventional procedure with a high success rate and few MACE. It may reduce restenosis rate.
