Abstract

Stroke is the culmination of a heterogeneous group of cerebrovascular diseases that is manifested as ischemia or hemorrhage of one or more blood vessels of the brain. The occurrence of many acute cardiovascular events--such as myocardial infarction, sudden cardiac death, pulmonary embolism, critical limb ischemia, and aortic aneurysm rupture--exhibits prominent 24 h patterning, with a major morning peak and secondary early evening peak. The incidence of stroke exhibits the same 24 h pattern. Although ischemic and hemorrhagic strokes are different entities and are characterized by different pathophysiological mechanisms, they share an identical double-peak 24 h pattern. A constellation of endogenous circadian rhythms and exogenous cyclic factors are involved. The staging of the circadian rhythms in vascular tone, coagulative balance, and blood pressure plus temporal patterns in posture, physical activity, emotional stress, and medication effects play central and/or triggering roles. Features of the circadian rhythm of blood pressure, in terms of their chronic and acute effects on cerebral vessels, and of coagulation are especially important. Clinical medicine has been most concerned with the prevention of stroke in the morning, when population-based studies show it is of greatest risk during the 24 h; however, improved protection of at-risk patients against stroke in the early evening, the second most vulnerable time of cerebrovascular accidents, has received relatively little attention thus far.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Cerebrovascular and cardiovascular events exhibit a bimodal pattern.

    “It is known that cerebrovascular and cardiovascular events exhibit a bimodal pattern (116).”
  • Strokes follow a circadian rhythm with a major morning peak and a secondary early evening peak.

    “Strokes, for instance, follow a circadian rhythm with a major morning peak and a secondary early evening peak.”
  • Epidemiological data reveal a robust morning increase in adverse cardiovascular events, including stroke, myocardial infarction, serious ventricular arrhythmias, and sudden cardiac death.

    “Moreover, epidemiological data reveal a robust morning increase in adverse CV events, including stroke (7,8), myocardial infarction (9)(10)(11), serious ventricular arrhythmias (12), and sudden cardiac death (refs.11, 13, and Figure 1).”

    From Role of the circadian system in cardiovascular disease (2018) · cites this paper as [8]

  • Adverse cardiovascular events, including myocardial infarction, sudden cardiac death, and ischemic stroke, occur more frequently in the morning hours than at other times of the day and night in the general population.

    “the vulnerable period for an adverse CV event in the general population is in the morning, coinciding with a morning surge in BP (183)”

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.
