A study on the cost-effectiveness of coronary revascularization: introducing the simultaneous mimic health status model
利用同步方程系统中的MIMIC健康模型，分析经皮腔内冠状动脉成形术与冠状动脉搭桥术治疗多支冠状动脉疾病的成本效果，发现3年随访期内两种方法均未更优。
An econometric model is presented to compare the cost-effectiveness of two alternative procedures, percutaneous transluminal coronary angioplasty (PTCA) and coronary artery bypass surgery (CABG), for the treatment of multivessel coronary artery disease. This study utilizes the MIMIC (multiple indicator multiple cause) health model in a simultaneous equation system to analyse Emory Angioplasty Surgery Trial (EAST) data. This method eliminates the possibility of endogeneity bias, which may have affected the results of previous cost-effectiveness analyses on this topic. The empirical results indicate that neither procedure proves more cost-effective at 3 year follow-up.
