“…Considering the OA, the PR was found to be increased in severe PE [8][9][10][11][12] , a maternal condition in which vasoconstriction [13][14][15] and PW reflection [16][17][18] are also increased. On the other hand, a significant decrease in PR was observed after pharmacological vasodilation with nitric oxide donors in healthy young men 19 and even in women with severe PE 11 .…”

“…This increased re ection is caused by arterial stiffness and increased local vascular tone, which cause repetitive re ections of the waves along the systemic arterial tree between the heart and the arteries studied 20 . Therefore, the higher PR may re ect local arterial preclinical disease and its possibility for future progression to atherosclerosis 21 , early changes in microcirculatory compliance causing downstream hyperperfusion, or both. In female smokers, PR is increased, which may suggest arterial stiffness and distal hyperperfusion in women.…”

Vascular dysfunctions can progress and lead to stroke and cardiovascular disease, especially in smokers. The presence of particular vascular changes according to sex has been described and they can be identified by the Doppler method. This study evaluated Doppler velocimetry parameters of the ophthalmic artery (OA) and the middle cerebral artery (MCA) according to sex in smokers regarding a non-smoker group. This cross-sectional observational study included 178 subjects: 93 women and 85 men. Doppler parameters were assessed in OA and MCA. Student’s t-test was used, with p < 0.05. There were no significant differences in OA and MCA Doppler velocimetry data between male non-smokers and smokers. However, female smokers presented several differences compared with non-smokers: lower pulsatility index (PI) and higher peak ratio and second peak of systolic velocity in OA, and higher PI and resistance index and lower end diastolic velocity in MCA. There were different brain vascular waveforms in the group of female smokers compared with non-smokers. Cigarette smoking also led to opposite arterial patterns in OA and MCA in the female group, with signs of falling impedance in OA and increased impedance in MCA. An individualised approach regarding arterial changes according to sex is desirable.

“…Its increase has been correlated to hyperperfusion 16 or to waveform change caused by the sum of the incident wave travelling towards the periphery and the early return of the reflected wave returning from the periphery reflecting on the systole and raising P2 15 . This increased reflection is caused by arterial stiffness and increased local vascular tone, which cause repetitive reflections of the waves along the systemic arterial tree between the heart and the arteries studied 17 . Therefore, the higher PR may reflect local arterial preclinical disease and its possibility for future progression to atherosclerosis 18 , early changes in microcirculatory compliance causing downstream hyperperfusion, or both.…”
