Morphologic aspects of myocardial infarction in patients with STEMI and no-reflow phenomenon after primary PCI
| Coronary branch | Territory affected | Approximate age of lesion | Number of cases |
|---|---|---|---|
| Left anterior descending coronary artery | Anterior and interventricular septum | 24–120 hours | 2 |
| Left circumflex coronary artery | Lateral part of the left ventricle | 48–72 hours | 1 |
| Right coronary artery | Posterior part of the left ventricle | 24–96 hours | 2 |
Gross and Histological Features in STEMI Patients Exhibiting the No-Reflow Phenomenon
| Macroscopy | |
| Fig. 4.1. Posterior myocardial infarction (2–3 days old): Gross appearance with early transmural ischemic changes. | Fig. 4.2. Posterolateral myocardial infarction (4–5 days old): Full-thickness infarction observed during autopsy. |
| Microscopy | |
| Fig. 4.3. H&E stain, 10×: Transmural necrosis with prominent neutrophilic infiltration in the interstitial space. | Fig. 4.4. H&E stain, 4×: Myocardial rupture with disorganized tissue architecture and interstitial hemorrhage. |
| Fig. 4.5. H&E stain, 20×: Detailed visualization of a fissure between necrotic myocardial fibers. | Fig. 4.6. H&E stain, 20×: Thrombosed myocardial region accompanied by inflammatory cell infiltration and necrosis. |
