Electrocardiogram. QS complex in V1, absence of R-wave progression in V2–V4, ST depression in leads II, III, and aVF.
Figure 2
Angiogram of the left coronary artery. Coronary angiography (12 hours post-symptom onset) revealed a mural thrombus in the proximal left anterior descending artery (LAD) with TIMI III flow and no signs of atherosclerosis, dissection, or vasospasm.
Figure 3
Angiogram of the right coronary artery. The right coronary artery is normal.
Figure 4
Electrocardiogram (discharge). Persistent QS complex in V1–V2, minimal R-wave in V3 (1 mm), no positive dynamics in V4, confirming completed transmural Q-wave MI.
