Abstract

OBJECTIVE: Anxiety predicts cardiovascular events, although the mechanism remains unclear. We hypothesized that anxiety symptoms will correlate with impaired resistance and conduit vessel function in participants aged 55 to 90 years. METHODS: Anxiety symptoms were measured with the Symptom Checklist-90--Revised in 89 participants with clinically diagnosed atherosclerotic cardiovascular disease and 54 healthy control participants. Vascular function in conduit arteries was measured using flow-mediated dilatation, and vascular function in forearm resistance vessels (FRVs) was measured using intra-arterial drug administration and plethysmography. RESULTS: Anxiety symptoms were not associated with flow-mediated dilatation in either group. Participants with atherosclerosis exhibited significant inverse associations of anxiety symptoms with FRV dilatation (acetylcholine: β = -.302, p = .004). Adjustment for medication, risk factors, and depression symptoms did not alter the association between anxiety and FRV dysfunction, except for body mass index (BMI; anxiety: β = -.175, p = .060; BMI: β = -.494, p < .001). Although BMI was more strongly associated with FRV function than anxiety, combined BMI and anxiety accounted for greater variance in FRV function than either separately. Control participants showed no association of anxiety with FRV function. CONCLUSIONS: Anxiety is uniquely and substantially related to poorer resistance vessel function (both endothelial and vascular smooth muscle functions) in individuals with atherosclerosis. These relationships are independent of medication, depression, and cardiovascular risk factors, with the exception of BMI. These findings support the concept that anxiety potentially increases vascular events through worsening of vascular function in atherosclerotic disease.

  • In adults with atherosclerosis, anxiety is independently associated with lower forearm resistance microvascular function after adjustment for cardiovascular disease risk factors.

    “Stillman et al. (2013) found a significant independent association between anxiety and decreased forearm resistance microvascular function after controlling for CVD risk factors in adults with atherosclerosis [11].”

    The Discussion reports that anxiety was associated with impaired forearm resistance vessel function in participants with atherosclerosis, independently of most conventional risk factors. But the Results show that, in a model including BMI and other significant covariates, anxiety only trended toward significance (p=0.054); the claim omits this exception to its assertion of a significant independent association after risk-factor adjustment.

  • Anxiety is not associated with peripheral conduit artery endothelial function measured by brachial artery flow-mediated dilation, suggesting that endothelial dysfunction in anxiety is selective to the resistance artery microcirculation.

    “In contrast, there was no association between anxiety and peripheral conduit artery endothelial function as assessed by brachial artery flow-mediated dilation (FMD), suggesting that vascular endothelial dysfunction in individuals with anxiety is selective to the resistance artery microcirculation rather than larger conduit muscular arteries.”

    The Results and the Discussion’s ‘Resistance versus conduit vessels’ section report no association between anxious symptoms and brachial FMD, alongside an association with resistance-vessel dysfunction in participants with atherosclerosis. The claim extends that pattern to individuals with anxiety generally, although the reported resistance-vessel finding is specific to participants with atherosclerosis. The study also reports vascular smooth muscle dysfunction, not only endothelial dysfunction. (LLM, conf=0.86)

  • Stillman et al. (2013) demonstrated that forearm resistance artery function was associated with anxiety in older adults with atherosclerosis, but there was no relation with peripheral conduit artery endothelial function as assessed by brachial artery FMD.

    “Stillman et al. (2013) demonstrated that forearm resistance artery function, as assessed by in response to intra-brachial artery infusions of endothelial-dependent and –independent pharmacological agonists, was associated with anxiety in a cohort of older adults with a history of atherosclerosis. In contrast, there was no relation with peripheral conduit artery endothelial function as assessed by”

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.
