Cerebrovascular pulsatility index is higher in chronic kidney disease [PDF]

Physiological Reports, 2023
Patients with chronic kidney disease (CKD) are more likely to die of cardiovascular diseases, including cerebrovascular disease, than to progress to end‐stage kidney disease.

Application of the intracranial arterial pulsatility index for determination of prognosis after lacunar infarct [PDF]

Advanced Biomedical Research, 2023
Background: We aimed to investigate the usefulness of intracranial arterial pulsatility index to assess the prognosis of lacunar infarcts. Materials and Methods: Forty-nine patients with confirmed acute lacunar infarct were enrolled in the study.

Homocysteine and Pulsatility Index of Cerebral Arteries [PDF]

Stroke, 2009
Background and Purpose— A pulsatility index (PI) represents vascular resistance distal to an examined artery. The purpose of the present study was to evaluate an association between plasma total homocysteine (tHcy) and PIs of the cerebral arteries in patients with ischemic stroke.

Fetal liver blood flow distribution: role in human developmental strategy to prioritize fat deposition versus brain development [PDF]

, 2012
Among primates, human neonates have the largest brains but also the highest proportion of body fat. If placental nutrient supply is limited, the fetus faces a dilemma: should resources be allocated to brain growth, or to fat deposition for use as a ...

The Impact of Aging on the Association Between Aortic Stiffness and Cerebral Pulsatility Index

Frontiers in Cardiovascular Medicine, 2022
The central arteries dampen the pulsatile forces from myocardial contraction, limiting the pulsatility that reaches the cerebral vasculature, although there are limited data on this relationship with aging in humans.

Maternal haemodynamic function differs in pre‐eclampsia when it is associated with a small‐for‐gestational‐age newborn: a prospective cohort study [PDF]

, 2021
Objective To describe maternal haemodynamic differences in gestational hypertension with small‐for‐gestational‐age babies (HDP + SGA), gestational hypertension with appropriate‐for‐gestational‐age babies (HDP‐only) and control pregnancies.

Longitudinal Impact of Physical Activity on Brain Pulsatility Index and Cognition in Older Adults with Cardiovascular Risk Factors: A NIRS Study

Brain Sciences, 2021
Recent studies have shown that optical indices of cerebral pulsatility, including cerebral pulse amplitude, are linked to cerebrovascular health. A chronically higher cerebral pulsatility is associated with cognitive decline.

A comparison between uterine artery blood flow in fertile and unexplained infertile women by Doppler ultrasound using pulsatility index and resistance index

Advanced Medical Journal, 2022
Background and objectives: Infertility is the inability to conceive after one year of regular unprotected intercourse. Unexplained infertility is present if the basic fertility investigations are normal.
