Abstract
A 57-year-old man with no history of coronary artery disease was admitted for acute anterior ST-segment–elevation myocardial infarction caused by an occlusion of the proximal left anterior descending (LAD) coronary artery. The culprit artery was recanalized with direct stenting with an optimal result. Left ventricular ejection fraction was 40% with anteroapicoseptal akinesia. A positron-emission tomography study demonstrated reduced perfusion and borderline fluorine-18-fluorodeoxyglucose uptake in apical segments and adjacent anterior and septal wall, suggesting reduced viability in the distal LAD territory. Nine days after infarction, the patient underwent autologous bone marrow stem cell transplantation as a part of a research protocol. Bone marrow blood was aspirated under local anesthesia from both iliac crests. A total of 27.4×108 of …
