Ischemic cardiovascular diseases (ICVD),including ischemic stroke and coronary heart disease,has become the top cause of death in China [1].A 10-year ICVD risk prediction model in Chinese adults has been developed and validated,which involved seven parameters including sex,age,systolic blood pressure,total choles-terol,body mass index,current smoking status,and diabetes [2].Since this model requires information from questionnaire,invasive blood tests,and physical examinations,its practice in primary healthcare settings is limited [2].
