Prevalence,Characteristics,Treatment And In-hospital Outcomes Of Diabetes Mellitus In Patients With Acute Myocardial Infarction In China From The China Acute Myocardial Infarction Registry

Background:AMI has become a major cause of hospitalization and mortality in China over the last 3 decades.The prevalence of diabetes mellitus(DM)has also been dramatically increasing.But data on DM among patients with AMI in the Chinese population is lacking.Methods:The China AMI registry is a representative,prospective,multicenter,national registry that includes 108 hospitals across three levels(provincial,prefecture and county)from 31 provinces and municipalities throughout Mainland China.We analyzed the characteristics,treatments and risk-adjusted in-hospital outcomes of DM in patients with AMI registered from Jan 2013 through Mar 2014.Results:Among 25,197 patients with AMI,20%have DM.Known DM was more prevalent in Northern than Southern China(21.8%vs.17.2%,P<0.001)and among patients admitted to the larger,more urban hospitals(21.9%in provincial-level,19.9%in prefecture-level and 16.3%in county-level hospitals).During the hospitalization,aspirin,P2Y12 receptor inhibitor and statin use was high(>90%for each).The in-hospital mortality rate in patients with AMI and DM was higher than that without DM(Adjusted OR=1.32,95%CI:1.05-1.68,P<0.05).Conclusions:DM is prevalent in patients with AMI,with regional differences in China.Patients with DM had higher in-hospital mortality than those without DM.Further appreciation and treatment of DM in China and efforts to reduce in-hospital mortality of AMI are needed.
