Objective:To investigate the cost--utility of coronary heart disease percutaneous coronary intervention in 13 cities in China.Methods:(during the first half year of 2006 630 patients undergoing pci were enrolled in this study.life-quality and cost were assessed prospectively for 613 patients over 12-month follow-up period.)the strategy we used was cost-utility analysis.the main outcome was the cost per gained mark of the 36 items short form of health survey(SF-36)and quality adusted life year(QALY)after 9-month of follow-up.Results:The average sore is increased by 20.59,which is statistically significant.the cost-effective analysis indicate that the cost per one incremental mark of SF-36 would be 2611.92 RMB and per QALY would be 78384.91 RMB.Conclusion:Percutaneous intervention therapy is effective for coronary heart disease after 9-month follow-up.this analysis provide an example of how to evaluate cost-utility of percutaneous coronary intervention.the cost per QALY is located in a acceptable range.
Objective:Confirming complete neointimal coverage after implantation of drug-eluting stent(DES)is clinically important because incomplete stent coverage is maybe responsible for late thrombosis and sudden cardiac death.Optical coherence tomography(OCT)is a high-resolution(≈10 μm)imaging technique capable of detecting a thin layer of neointimal hyperplasia(NIH)inside DES.Helios stent system(KinheIy Bio-tech Co(Shenzhen).Ltd)is a new generation of sirolimus eluting stents.Methods:Motorized optical coherence tomographic pullback was performed at 9-month follow-up to examine consecutive Helios stent mplantations in 10 patients.NIH thickness inside each strut and NIH area percentage inside each cross-section were measured.Results:In total,2063 struts in 296 mm stented segments were analyzed.Overall,NIH thickness were(95.7±66.62)μm,rates of exposed struts was 60.2% and the average NIH area percentage was 5.0618% ± 5.6625%.Conclusion:Our study suggests that dual antiplatelet therapy after Helios stent implantation must be continued at least 9months after DES implantation.
Objective:To study the hospitalization expense and its main influencing factors of the percutaneous coronary intervention inpatients in 13 cities of China,so as to control the medical expenses and utilize medical resources effectively.Methods:Data were collected from medical insurance organizations and 630 selected inpatients.Multivariable regression analysis and ANOVA analysis were used to disclose the major factors affecting inpatient cost by Eviews3.1 and SPSS 11.5.Results:The major factors of inpatient cost were GDP,the number and price of stents,medical insurance type,of which the stent number and price were critical.Conclusion:The key point of controlling inpatient cost was to control the stent number,decrease the stent price and regulate the medical insurance policy.[LM]
