Instantaneous and sudden deaths. Clinical and pathological differentiation in coronary artery disease
Abstract
A study of 59 persons dying of coronary artery disease revealed that persons dying instantaneously differed from persons dying suddenly of coronary artery disease in that (1) they rarely experienced acute symptoms or exhibited acute signs before death; (2) more than one half died during or immediately after physical exertion; (3) their deaths appeared to result from a primary arrhythmia; and (4) their hearts rarely showed an acute lesion of any kind and frequently exhibited two old occluded coronary arteries or one old occluded, left anterior descending artery. These latter differences should permit angiographic detection of many persons prone to instantaneous death.

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.
