Agreed, @ershanno. I know in past OHDSI trainings (and in the cohort definition in Atlas Phenotype), we’ve simply excluded old MI from the MI standard concept, but it does look like concept 45766114 (Subsequent ST segment elevation myocardial infarction) could be a candidate for exclusion as well. I am trying to see if this concept truly acts a “subsequent” event in our data.
The ICD9CM range for old subsequent MIs (410.x2) do not seem to map to anything about the event being subsequent. Perhaps a mapping fix is needed?
