Key result
Carotid plaque score (B 0.007; 95% CI 0.003-0.010) and intima-media thickness (B 0.173; 95% CI 0.120-0.226) were independently associated with middle cerebral artery pulsatility index.
Why the study?
Several cardiovascular risk factors are common to both middle cerebral artery pulsatility index and carotid atherosclerosis, leading researchers to hypothesize an association between them.

Should not yet inform clinical cerebrovascular assessment; hypothesis-generating for links between carotid atherosclerosis and MCA pulsatility.

Effect estimate: B 0.007 (95% CI 0.003-0.010)
Ultrasound-derived indices of carotid atherosclerosis are independently but weakly associated with middle cerebral artery pulsatility index in middle-aged adults.
Vigen et al. (2019) conducted a cross-sectional in Carotid atherosclerosis (n=3,154). Carotid atherosclerosis indices (ultrasound-derived) was evaluated on Middle cerebral artery pulsatility index (MCA PI) (B 0.007, 95% CI 0.003-0.010). Carotid plaque score (B 0.007; 95% CI 0.003-0.010) and intima-media thickness (B 0.173; 95% CI 0.120-0.226) were independently associated with middle cerebral artery pulsatility index.
