2007年在德国共进行了38万例冠状动脉支架植入手术。根据冠状动脉支架类型(裸金属支架与药物涂层金属支架)不同,病变部位发生再狭窄的比率也不同,再次手术的发生率介于8%~20%之间。再次植入支架或进行PT-CA导管术以及进一步的药物伴随治疗将会发生很高的费用。对于裸金属冠状动
In 2007, a total of 380,000 coronary stent procedures were performed in Germany. Depending on the type of coronary stent (bare metal stent and drug-coated metal stent), the rate of restenosis at the lesion site is also different, and the rate of reoperation is between 8% and 20%. Re-implanting the stent or performing PT-CA catheterization and further drug concomitant therapy can incur significant costs. For bare metal coronaries
