Term: Post-Acute Myocardial Infarction (AMI) Care: Beta-Blocker Prescribing

Glossary Definition

Last Updated: 2020-05-19

Definition:

The crude percentage of patients with a diagnosis of acute myocardial infarction in five years of hospital discharge abstracts who filled at least one prescription for a beta-blocker within four months of their AMI. To be included in the denominator, patients had to be alive for the entire follow-up period.

Patients with the following diagnoses in hospital in the three years prior to the index event are excluded because beta-blockers are contra-indicated for patients with these conditions:

• asthma (ICD-9-CM diagnosis code 493 or ICD-10-CA code J45),
  
• COPD (ICD-9-CM diagnosis codes 491 and 492 or ICD-10-CA codes J41-J44) or
  
• peripheral vascular disease (ICD-9-CM diagnosis code 443 and 459 or ICD-10-CA codes I73, I79.2, and I87).
