两年前的一天,张春林因劳力型心绞痛与老伴到北京某大型医院就诊。检查完,医生告诉他,病情非常危险,建议在冠状动脉内安装支架进行治疗。 One day two years ago, Zhang Chunlin and his wife visited a large hospital in Beijing for labor-type angina. After the examination, the doctor told him that the condition is very dangerous and it is recommended that stents be installed inside the coronary artery for treatment.
