目的了解中国与加拿大急性心肌梗死(AMI)的治疗方式和住院死亡率的差别,为提高中国AMI患者的治疗质量提供依据。方法采用χ2检验对中国与加拿大AMI患者的冠状动脉造影率、介入治疗率和冠状动脉搭桥术率及住院死亡率的差别进行比较。结果中国冠状动脉造影率(68.48%)和冠状动脉搭桥术率(2.3%)均低于加拿大(72.39%,8.7%),差异有统计学意义(P<0.05);介入治疗率(91.68%)和住院死亡率(10.18%)均高于加拿大(56.98%,4.90%),差异有统计学意义(P<0.05)。结论介入治疗在中国已经成为AMI治疗的重要手段,但冠状动脉搭桥术的使用与加拿大相比还存在一定差距。
Objective To understand the difference between hospitalization and inpatient mortality of acute myocardial infarction (AMI) in China and Canada, and to provide basis for improving the quality of treatment in AMI patients in China. Methods The χ2 test was used to compare the rates of coronary angiography, interventional therapy, coronary artery bypass surgery, and hospital mortality in AMI patients from China and Canada. Results The rates of coronary artery angiography (68.48%) and coronary artery bypass grafting (2.3%) in China were lower than those in Canada (72.39%, 8.7%, P <0.05) (10.18%) were higher than that of Canada (56.98%, 4.90%), the difference was statistically significant (P <0.05). Conclusion Interventional therapy has become an important treatment for AMI in China. However, there is still a gap between the use of coronary artery bypass grafting and that of Canada.
