The patient's first electrocardiogram after the blunt trauma shows ST evaluation and T wave inversion in the I, avL, and V2-V5 leads and the left anterior branch block.

Coronary angiography image from the right anterior oblique shows a curved lesion with approximately 70% narrowing of the lumen in the proximal of left anterior descending coronary artery.

To confirm the stenosis and examine the condition of the coronary intimal, CAG was performed at 3 months after the chest trauma, which showed approximately 70% narrowing of the lumen in the proximal LAD (Fig. 2) and the coronary segment had a curved lesion.
Coronary angiography image from the right anterior oblique shows that the curving of the lesion is slightly reduced compared to that in the its previous condition.

There was approximately 60% narrowing of the lumen (Fig. 3).
The image shows rS in V2-V4 leads; T wave inversion in the I, avL, and V2 to V5 leads; and the left anterior branch block.

M-mode echo shows that the movement of interventricular septum was almost disappeared. Thinning of the interventricular septum is seen, with the thinnest part being 4.7-mm thick, and the echo was enhanced.

Transthoracic echocardiography (Fig. 5) showed left heart enlargement with 39-mm left atrium, 54.7-mm left ventricle, and LV EF of 41% (Simpson's). Thinning of the LV anterior wall and interventricular septum was also noted, with the thinnest part being 4.7 mm; movement had almost disappeared and the echo was enhanced.
