AB  - BACKGROUND: Acute myocardial infarction (AMI) type is an important distinction to 
      be made in both clinical and health care research context, as it determines the 
      treatment of the patient as well as affecting outcomes. The aim of the paper was 
      to determine the feasibility of distinguishing AMI type, either ST elevation 
      myocardial infarction (STEMI) or non-ST elevation myocardial infarction (NSTEMI), 
      using ICD10 codes. METHODS: We carried out a retrospective descriptive analysis 
      of hospital administrative data on AMI emergency patients in England, for 
      financial years 2000/1 to 2009/10. We used the performance of an angioplasty 
      procedure on the same day and on the same or next day of hospital admission as a 
      proxy for STEMI. RESULTS: Among the ICD10 AMI subcategories, there were 
      inconsistent trends, with some of the codes exhibiting a gradual decline (such as 
      I21.0 Acute transmural myocardial infarction of anterior wall, I21.1 Acute 
      transmural myocardial infarction of inferior wall, I22.0 Subsequent myocardial 
      infarction of anterior wall and I22.1 Subsequent myocardial infarction of 
      inferior wall) and other codes an increase (in particular I21.9 Acute myocardial 
      infarction, unspecified and I22.9 Subsequent myocardial infarction of unspecified 
      site). With the exception of the codes I21.4 Acute subendocardial myocardial 
      infarction, I21.9 Acute myocardial infarction, unspecified, I22.8 Subsequent 
      myocardial infarction of other sites and I22.9 Subsequent myocardial infarction 
      of unspecified site, all the other AMI subcategories appear to have undergone a 
      significant increase in the number of angioplasty procedures performed the same 
      or the next day of hospital admission from around 2005/6. There appear to be 
      difficulties in accurately identifying the proportion of STEMI/NSTEMI by sole 
      reliance on ICD10 codes. CONCLUSIONS: We suggest as the best sets of codes to 
      select STEMI cases I21.0 to I21.3, I22.0, I22.1 and I22.8; however, without any 
      further adaptations, ICD10 codes are insufficient to clearly distinguish acute 
      myocardial infarction type.
