Caffeine increases aortic stiffness in hypertensive patients
Abstract
BACKGROUND: Caffeine is the most widely used pharmacologic substance. Aortic stiffness is an important factor for cardiovascular system performance and a prognosticator of cardiovascular risk. We investigated the effect of caffeine on aortic stiffness in treated hypertensive patients. METHODS: We studied the effect of caffeine (250 mg) in 12 treated hypertensive patients according to a randomized, placebo-controlled, double-blind, cross-over design during a 3-h period. Aortic stiffness was evaluated by carotid-femoral pulse wave velocity. RESULTS: Systolic blood pressure (BP) and pulse pressure increased significantly throughout the study (by 12.3 and 7.4 mm Hg, P =.005 and P <.01, respectively), whereas diastolic BP did not change. Pulse wave velocity increased (by 0.57 m/sec, P <.05) denoting an increase in aortic stiffness. This effect of caffeine lasted throughout the study (3 h), peaking at 60 min and decreasing progressively thereafter. CONCLUSIONS: These results demonstrate, for the first time, that caffeine exerts an acute unfavorable effect on aortic stiffness in treated hypertensive patients. This finding has important implications for the impact of caffeine consumption on cardiovascular risk in hypertension.

Active and passive smoking and caffeine separately increase arterial stiffness and wave reflections.
“We and others have previously shown that active and passive smoking (13)(14)(15) and caffeine (16 -19) increase arterial stiffness and wave reflections.”

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.
