Case in brief
A 59-year-old patient experienced a myocardial infarction without diagnostic ST segment elevation on the 12-lead ECG. However, subtle abnormalities were noted in the anterior leads. Coronary angiography revealed occlusion of the left anterior descending coronary artery, highlighting the importance of recognizing these subtle ECG changes.
What made this case unusual
The case emphasizes the presence of newly appearing subtle anterior Q-waves, which are not typically associated with ST segment elevation but may indicate significant coronary artery occlusion.
Diagnostic / clinical pearl
Clinicians should be vigilant for subtle anterior Q-waves on ECG, as they may suggest left anterior descending coronary artery occlusion despite the absence of ST segment elevation.
