73 Possible Causes for Narrowed Vasculature

  • Hypertension

    […] with local tissue factors to maintain BP within a relatively narrow range ( Figure 1 ).[doi.org] Hypertensive retinopathy is most commonly manifested by generalized or focal narrowing of retinal arterioles.[doi.org] In health, despite potential changes to blood volume, CO and SVR, complex neural and hormonal homeostatic mechanisms involving the brain, heart, vasculature and kidneys combine[doi.org]

  • Essential Hypertension

    Hypertensive retinopathy is most commonly manifested by generalized or focal narrowing of retinal arterioles.[hyper.ahajournals.org] In acute or advanced hypertension, the retinal vasculature may be injured sufficiently to cause occlusion or leakage.[hyper.ahajournals.org]

  • Hypothyroidism

    Cardiovascular risk and heart failure Thyroid hormones are well known to act on the heart and vasculature, and the impact of subclinical thyroid dysfunction on the cardiovascular[doi.org] […] raising TSH levels over the lifetime and given the lack of evidence on adverse outcomes and therapeutic consequences in individuals with high normal TSH levels speak against narrowing[doi.org]

  • Hypertensive Crisis

    Hypertensive retinopathy is most commonly manifested by generalized or focal narrowing of retinal arterioles.[doi.org] In acute or advanced hypertension, the retinal vasculature may be injured sufficiently to cause occlusion or leakage.[doi.org]

  • Diabetic Nephropathy

    […] of glomerular vasculature by hyaline deposition).[symptoma.com] […] increase in matrix protein production) and glomerular sclerosis (secondary to intraglomerular hypertension, caused by afferent renal artery dilatation or ischemic injury due to narrowing[symptoma.com]

  • Arteriosclerosis

    This is technically called ischemia, the inadequate supply of blood to a tissue or organ due to obstructed or constricted vasculature.[study.com] What's worse is that these plaques predispose a person to the formation of blood clots that can further narrow or completely block the artery, or the blood clot or plaque[study.com]

  • Preeclampsia

    […] due to systemic ischemia that generate damage to the retinal and choroidal vasculature and to the retinal pigmentary epithelium.[eyewiki.aao.org] Eclampsia is new-onset generalized seizures in a woman with preeclampsia. [1] Disease Preeclampsia/eclampsia associated retinopathy is characterized by retinal arteriolar narrowing[eyewiki.aao.org]

  • Transient Ischemic Attack

    Also, carotid stenosis secondary to atherosclerosis narrowing the diameter of the lumen and thus limiting blood flow is another common cause of TIA.[en.wikipedia.org] A portion of the plaque can become dislodged and lead to embolic pathology in the cerebral vessels.In-situ thrombosis, an obstruction that forms directly in the cerebral vasculature[en.wikipedia.org]

  • Hypotension

    Hypertensive retinopathy is most commonly manifested by generalized or focal narrowing of retinal arterioles.[doi.org] In acute or advanced hypertension, the retinal vasculature may be injured sufficiently to cause occlusion or leakage.[doi.org]

  • Orthostatic Intolerance due to NET Deficiency

    The noradrenergic synaptic clefts in the heart are approximately three times as narrow as the synaptic clefts in the vasculature, 28 making the removal of norepinephrine from[nejm.org]
