Anti-Myosin Humoral Immune Response Following Cardiac Injury
Abstract
A sensitive and highly specific ELISA assay was developed to determine the anti-myosin humoral immune response (AMA) in various heart diseases: acute viral myocarditis, infective endocarditis, acute myocardial infarction, and valve and coronary bypass surgery. The mean study entry AMA titer of each patient group was already significantly increased compared with age matched controls. During further follow-up (90 d) all the groups except for endocarditis showed a significant increase of AMA titer compared with their entry titer. Anti-myosin antibody titer were higher after cardiac surgery than after myocardial infarction or inflammatory heart disease. These results suggest that anti-myosin immune response is not limited to infectious processes in which the pathogen induces antibodies which cross-react with heart constituents but is merely caused by direct cardiac injury. Myosin as a major compound of heart cellular proteins turned out to be a good candidate to trigger immune response after cardiac injury.

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.
