Concurrent Morning Increase in Platelet Aggregability and the Risk of Myocardial Infarction and Sudden Cardiac Death
Abstract
We have previously reported that the frequencies of myocardial infarction and of sudden cardiac death are highest during the period from 6 a.m. to noon. Since platelet aggregation may have a role in triggering these disorders, we measured platelet activity at 3-hour intervals for 24 hours in 15 healthy men. In vitro platelet responsiveness to either adenosine diphosphate (ADP) or epinephrine was lower at 6 a.m. (before the subjects arose) than at 9 a.m. (60 minutes after they arose). The lowest concentration of these agents required to produce biphasic platelet aggregation decreased (i.e., aggregability increased) from a mean +/- SEM of 4.7 +/- 0.6 to 3.7 +/- 0.6 microM (P less than 0.01) for ADP and from 3.7 +/- 0.8 to 1.8 +/- 0.5 microM (P less than 0.01) for epinephrine. The period from 6 to 9 a.m. was the only interval in the 24-hour period during which platelet aggregability increased significantly. We subsequently studied 10 subjects on alternate mornings after they arose at the normal time and after delayed arising. The morning increase in platelet aggregability was not observed when the subjects remained supine and inactive. Thus, there is a temporal association between increased platelet aggregability in the morning and an increased frequency of myocardial infarction and of sudden cardiac death. Demonstration of this association does not establish a cause--effect relation, but together with other evidence linking platelets to these disorders, it may provide insight into the mechanisms precipitating myocardial infarction and sudden cardiac death and aid in the design of more effective preventive measures.

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.
