Thrombosis and Acute Coronary-Artery Lesions in Sudden Cardiac Ischemic Death

Davies, Michael John, Thomas, Anthony·1984·New England Journal of Medicine

Abstract

The nature of the pathologic lesion in sudden cardiac ischemic death is in dispute. Among 100 subjects who died of ischemic heart disease in less than six hours, coronary thrombi were found in 74. There was no difference in incidence between those who died in less than 15 minutes, those who died in 15 to 60 minutes, and those who died after one hour. Among 26 cases without an intraluminal thrombus, plaque fissuring was found in 21; thus, in only 5 cases was no acute arterial lesion demonstrated. No intraluminal thrombi were found in age-matched controls. Forty-eight of the 74 thrombi were found at sites of preexisting high-grade stenosis; 14 were found at points of previous stenosis of less than 50 per cent of the diameter of the lumen. Forty-seven per cent of the thrombi were found in the right coronary artery. Only 30 per cent were found in the left anterior descending coronary artery. The pathologic process in sudden ischemic death involves a rapidly evolving coronary-artery lesion in which plaque fissuring and resultant thrombus formation are present. These findings have implications for the prevention of sudden cardiac death by antithrombotic therapy.

  • The integrity of the fibrous cap, comprising mostly αSMA-positive cells and associated ECM, is critical to stabilise and protect plaques from rupture.

    “detailed post-mortem analyses of culprit plaques in sudden cardiac death established that the integrity of the fibrous cap, comprising mostly α SMA-positive cells and associated extracellular matrix (ECM), is critical to stabilise and protect plaques from rupture, a major cause of the clinical sequalae of atherosclerosis 142,163,168 .”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
