What are the clinical and electrocardiographic characteristics of myocardial infarction after noncardiac surgery?
Perioperative myocardial infarction after noncardiac surgery is typically an early, often asymptomatic (lacking chest pain), non-Q wave event, highlighting the need for high clinical suspicion and routine surveillance.
This study determined that PMI was an early event, only occasionally associated with chest pain, and usually non-Q wave in nature.
Badner et al. (Sun,) studied this question.
