Abstract

Ruptured atheromatous plaques were identified by step-sectioning technique as responsible for 40 of 51 recent coronary artery thrombi and 63 larger intimal haemorrhages. The degree of pre-existing luminal narrowing at the site of rupture was decisive for whether plaque rupture caused occlusive thrombosis or just intimal haemorrhage. If the pre-existing stenosis was greater than 90% (histologically determined) then plaque rupture nearly always caused occlusive thrombosis. Clearly indicating the primary role of plaque rupture in thrombus formation were the frequent finding of plaque fragments deeply buried in the centre of the thrombus and the nature of the thrombus at the site of rupture where it consisted predominantly of platelets. Thus, a severe chronic stenosis seems to be a prerequisite for occlusive thrombus formation, but the thrombotic process itself is triggered by an acute intimal lesion.

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.
