- Abstract
A 72-year-old woman with hypertension, dyslipidemia, and diabetes mellitus presented to our hospital because of the sudden onset of chest pain. Emergency coronary angiography showed acute occlusion of the distal left anterior descending artery and coronary intervention with a drug-eluting stent was performed. Sudden cardiopulmonary arrest occurred on the sixth day of hospitalization, but coronary angiography showed no remarkable progression of the coronary artery diseases, including the site of stent implantation. An autopsy revealed that the cause of the sudden death was apical free wall rupture. In addition, the different timing of acute and sub-acute infarct findings were observed in the apical wall by histology, which indicated cardiac rupture was due to reinfarction at early phase of apical acute myocardial infarction. Although the rate of mechanical complications, including cardiac rupture, is decreasing in the era of primary coronary intervention, in addition to the well-known risk factors of cardiac rupture, the reinfarction of the culprit myocardial site in the early phase of acute myocardial infarction was considered as a possible risk factor of cardiac rupture.
