Abstract

Acute caffeine in subjects who do not normally ingest methylxanthines leads to increases in blood pressure, heart rate, plasma epinephrine, plasma norepinephrine, plasma renin activity, and urinary catecholamines. Using a double-blind design, the effects of chronic caffeine administration on these same variables were assessed. Near complete tolerance, in terms of both humoral and hemodynamic variables, developed over the first 1-4 d of caffeine. No long-term effects of caffeine on blood pressure, heart rate, plasma renin activity, plasma catecholamines, or urinary catecholamines could be demonstrated. Discontinuation of caffeine ingestion after 7 d of administration did not result in a detectable withdrawal phenomenon relating to any of the variables assessed.

  • These opinions and advisories are based upon a relatively small collection of caffeine studies.

    “These opinions and advisories are based upon a relatively small collection of caffeine studies that have been publicised in both scientific and lay literature and in the media over the past few decades [10], [17], [25].”

    From No Evidence of Dehydration with Moderate Daily Coffee Intake: A Counterbalanced Cross-Over Study in a Free-Living Population (2014) · cites this paper as [25]

    The Introduction says chronic effects of caffeine have received considerably less study and that conclusions about them have largely been extrapolated from acute studies or epidemiological investigations. That supports a limited evidence base for chronic effects, but the paper does not establish that the cited opinions and advisories were based on a small collection of studies or discuss their publicity in scientific, lay, or media outlets. (LLM, conf=0.78)

    Experimental — accuracy not yet measured
  • Caffeine acutely increases peripheral vascular resistance.

    “In short-term studies, it has been shown to increase blood pressure and peripheral vascular resistance, but tolerance rapidly develops. 4”

    From Acute Effect of Caffeine on Arterial Stiffness and Aortic Pressure Waveform (2001) · cites this paper as [4]

    The Results report an acute rise in systolic blood pressure, and the Discussion says tolerance to that rise develops with continued caffeine use. The paper does not report an increase in peripheral vascular resistance; its Discussion instead says a direct effect on vascular resistance is unlikely to explain the pressor response (page not available in our copy). (LLM, conf=0.88)

  • Tolerance to caffeine's hemodynamic effects rapidly develops.

    “In short-term studies, it has been shown to increase blood pressure and peripheral vascular resistance, but tolerance rapidly develops. 4”
  • Caffeine acutely increases blood pressure.

    “In short-term studies, it has been shown to increase blood pressure and peripheral vascular resistance, but tolerance rapidly develops. 4”
  • Earlier studies claiming tolerance to pressor effects of caffeine did not mirror normal staggered caffeine consumption.

    “Earlier studies which claimed to show tolerance to the pressor effects of caffeine [11,[16][17][18] have not mirrored 'normal' staggered caffeine consumption but are characterized by a prior period of prolonged abstinence followed by a high dose of caffeine administered once or twice daily.”

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.
