Key result
Paretic sides show ~6 mmHg higher central systolic BP than non-paretic sides after chronic stroke.
Why the study?
Vascular changes can be a risk factor for recurrent and new stroke events, but little is known regarding variables related to aortic pulse wave morphology in stroke individuals.
Are there differences in aortic pulse wave morphology between the paretic and non-paretic sides in individuals after chronic stroke?
Cross-Sectional
Are there differences in aortic pulse wave morphology between the paretic and non-paretic sides in individuals after chronic stroke?
Peripheral vascular changes after chronic stroke affect heart-vascular coupling, leading to higher arterial stiffness and blood pressure parameters on the paretic side.
Suggests asymmetric vascular changes post-stroke; hypothesis-generating and should not yet change practice.

Silva et al. (2023) conducted a cross-sectional in Chronic stroke. Paretic side vs. Non-paretic side was evaluated on Aortic pulse wave morphology (arterial stiffness indices, hemodynamics and vascular variables). Aortic pulse wave parameters, including central systolic blood pressure (mean difference -6.17; 95% CI -9.74 to -2.59), were higher in the paretic compared to non-paretic side after chronic stroke.
