Non-Q Wave Myocardial Infarction. Assessment and Management of a Unique and Diverse Subset

Acute cardiac events involving coronary symptoms, elevated enzyme levels, and electrocardiographic changes without the development of Q waves often result in higher rates of reinfarction and unstable angina than do more severe myocardial infarctions. The incidence of these non-Q wave events is on the rise, possibly because of earlier detection and treatment of heart disease. Familiarity with the characteristics and management of the condition, therefore, is more important than ever.
