Adjustment was made for the variables listed in the table, smoking status, facility characteristics, chronic blood loss anemia, deficiency anemia, psychosis, alcohol abuse, drug abuse and calendar year.

^*The comparator group is hospitalized patients who did not undergo surgery.

^**For all variables, comparator group were those patients without STEMI
