Acute myocardial infarction (AMI) mortality rate (number of deaths per 1,000 discharges for AMI)

Measure Source

Agency for Healthcare Research and Quality (AHRQ) Inpatient Quality Indicators (IQI).


1.55 Deaths per 1,000 admissions with acute myocardial infarction (AMI) as principal diagnosis, age 18 and older (excluding transfers to another hospital), United States, 2001 and 2002.

Data Source

AHRQ, Center for Delivery, Organization, and Markets, Healthcare Cost and Utilization Project (HCUP), Nationwide Inpatient Sample.


All hospital inpatient discharges age 18 and older with a principal diagnosis code of AMI (ICD-9-CM 41001, 41051, 41011, 41061, 41021, 41071, 41031, 41081, 41041, 41091).

Excludes patients transferring to another short-term hospital and obstetric and neonatal admissions.


Number of deaths with a principal diagnosis code of AMI.


Rates are adjusted by age, gender, age-gender interactions, and APR-DRG risk of mortality score. When reporting is by age, the adjustment is by gender and APR-DRG risk of mortality score; when reporting is by gender, the adjustment is by age and APR-DRG risk of mortality score.

Although not all States participate in the HCUP database, the Nationwide Inpatient Sample is weighted to give national estimates using weights based on all U.S. community, non-rehabilitation hospitals in the American Hospital Association Annual Survey of Hospitals.

This table was created using version 2.1, revision 3, of the AHRQ IQI software. This measure is referred to as indicator 15 in the software documentation. More information about the AHRQ Quality Indicators is available at
