The corpse showed hypertrophy of skeletal musculature, with low amount of subcutaneous fat and several tattoos in shoulders, arms, thighs, and thorax (Figure 1).
Macroscopic examination of the heart: areas of scarring located at the intersection between the posterior wall and the posterior third of the septum (postero-septal).

The ventricular thickness was within the upper normal ranges (left ventricular free wall 15 mm, ventricular septum 15 mm, right ventricular free wall 5 mm) (Figure 2). Areas of scarring were located at the intersection between the posterior wall and the posterior third of the septum (postero-septal) (Figure 2).
Macroscopic examination of the coronary arteries: severe atherosclerosis with acute occlusive thrombosis at the left main trunk and left anterior descendant.

Coronary arteries, with a right dominance, had a normal origin and course, showing severe atherosclerosis (>75% stenosis) with acute superimposed occlusive thrombosis at the left main trunk and left anterior descendant (LAD) (Figure 3).
Early acute myocardial infarction at the anterior third of the septum and left ventricle anterior wall: wave fibers with elongation and narrowing as an early sign of acute ischemic damage and mild edema (HE, x10).

Acute myocardial infarction at the anterior third of the septum and the left ventricle (LV) anterior wall (Figure 4), subacute myocardial infarction at apical septum and apical posterior LV wall (Figure 5), myocytes hypertrophy (Figure 6) and small intramyocardial vessel disease (Figure 7) were detected.
Subacute myocardial infarction at the left ventricular free wall and septum: loose connective tissue with capillaries and inflammatory infiltrate (HE, x10).

Acute myocardial infarction at the anterior third of the septum and the left ventricle (LV) anterior wall (Figure 4), subacute myocardial infarction at apical septum and apical posterior LV wall (Figure 5), myocytes hypertrophy (Figure 6) and small intramyocardial vessel disease (Figure 7) were detected.
Myocytes hypertrophy with dysmetric and dysmorphic nuclei (HE, x10).

Acute myocardial infarction at the anterior third of the septum and the left ventricle (LV) anterior wall (Figure 4), subacute myocardial infarction at apical septum and apical posterior LV wall (Figure 5), myocytes hypertrophy (Figure 6) and small intramyocardial vessel disease (Figure 7) were detected.
Small intramyocardial vessels disease with media hypertrophy (Masson Trichrome 20x).

Severe atherosclerosis with acute occlusive thrombosis at the (A) left main trunk (Masson Trichrome, x2), and (B) left anterior descendant (Masson Trichrome, x4).
