Characteristics and Outcomes of Type 1 versus Type 2 Perioperative Myocardial Infarction After Noncardiac Surgery.

ABSTRACT:

Background

Perioperative myocardial infarction is frequently attributed to type 2 myocardial infarction, a mismatch in myocardial oxygen supply-demand without unstable coronary artery disease. Our aim was to identify characteristics, management, and outcomes of perioperative type 1 versus type 2 myocardial infarction among surgical inpatients.

Methods

Adults age ≥45 years hospitalized for noncardiac surgery were identified in the United States. Perioperative myocardial infarction were identified using International Classification of Diseases, 10th revision (ICD-10) codes. Clinical characteristics, invasive myocardial infarction management, mortality, and readmissions were assessed by myocardial infarction subtype.

Results

Among 4,755,382 surgical hospitalizations, we
