Purpose: The purpose of this study was to compare plaque characteristics of native coronary atherosclerosis and in-stent neointima ten months after ST elevation myocardial infarction (STEMI) using iMap intravascular ultrasound (IVUS). Methods: In 49 patients in-stent neointima and the coronary segment proximal to the stent were analyzed with iMap intravascular ultrasound (IVUS) ten months after primary PCI for STEMI. Results: A higher percentage of necrotic tissue was observed in the proximal coronary segment compared to the in-stent neointima by iMap IVUS (25.5%. ±. 12.8% vs 12.3%. ±. 3.3%, p. <. 0.0001) ten months after STEMI. The proportion of fibrotic tissue in the proximal segment was lower (63.6%. ±. 14.8% vs 72.0%. ±. 5.7%, p. =. 0.002) and the proportion of the lipidic tissue was higher (8.8%. ±. 3.0% vs 5.9%. ±. 2.0%, p. <. 0.0001) than in-stent neointima. Conclusions: In patients ten months after STEMI, in-stent neointima contained a higher proportion of fibrotic tissue and lower proportion of necrotic and lipidic tissue compared the native atherosclerotic lesion.
