Abstract 16691: Improving Trends of In-Hospital Mortality Among AMI Patients With Diabetes
Background: Ischemic heart disease is the leading cause of death among patients with Diabetes Mellitus (DM). Prior reports have shown improved albeit persistently higher mortality among diabetics with acute myocardial infarction (AMI) compared to non-diabetics. Whether advances in treatment have resulted in improved short term outcomes among diabetics with AMI remains unknown.
Methods: We examined data from the National Inpatient Survey from 2000-2010 and identified patients discharged with a diagnosis of AMI (ICD-9 code 410.0-410.9). Temporal trends in crude and age adjusted mortality were compared among patients with and without DM.
Results: From 2000 to 2010, a total of 7,590,780 patients presented with AMI including 2,137,639 patients with DM (28%). Overall prevalence of DM increased over the study period (25.8% in 2000 to 32.7% in 2010, p<0.01 for trend). There was a significant and steady decline in mortality among both DM and non-DM patients (8.0% vs. 8.5% in 2000 and 4.8% to 5.6% in 2010, respectively, p<0.01) (figure 1) with an improvement in odds ratio of death related to diabetes from 0.93 (0.91-0.95) in 2000 to 0.86 (0.84-0.89) in 2010 (p<0.01).
Conclusions: Despite an increase in prevalence of cardiovascular risk factors including DM, overall in-hospital mortality has significantly decreased among diabetics and non-diabetics with AMI.
