non-Q-wave myocardial infarction
Pathology:
- patients with non-Q-wave MI tend to develop platelet-rich (white) subocclusive thrombi in contrast to larger, occlusive erythrocyte-rich thrombi of Q-wave MI
Laboratory:
- markers of myocardial infarction
- diagnosis is commonly made only retrospectively on the basis of elevated cardiac enzyme levels after the event
Special laboratory:
- electrocardiogram
- not associated with evolution of new Q waves
Management:
- non-Q-wave MI tends to respond more favorably to thrombolytic therapy
- also see myocardial infarction
Notes:
- the diagnosis of non-Q-ave MI is often difficult to make soon after the event & is commonly made only retrospectively on the basis of elevated cardiac enzyme levels
