Abstract:
:We present the clinical and postmortem findings in seven adults (four females and three males), who died with dissection of the coronary arteries. The median age was 56 years. Five of the coronary artery dissections (CADs) were spontaneous and two followed trauma: one a motor vehicle accident, the other occurred during angiography. Four cases died suddenly or within 30 minutes. Three had symptoms of at least 24 hours duration and, not unexpectedly, had histological evidence of myocardial infarction. Four dissections involved the left anterior descending coronary artery, two the right coronary artery and one a dominant circumflex artery. Histological examination of the dissected arteries in four cases demonstrated necrosis of the medial smooth muscle which was intimately related to intimal tears and/or an inflammatory reaction. From a review of the literature and this study of seven cases, we conclude that CAD is multifactorial in causation and has a wide spectrum of clinical presentations. Presently the role of coronary vasospasm and prior trauma appears underestimated, and in many cases of CAD the nature of the primary initiating event remains open to speculation.
