What is it about?
Blood pressure measured in the brachial artery does not represent the impedance of the left ventricular outflow tract. Central pressure values depend on the magnitude of the incident and reflected pressure waves. We have shown that the magnitude of the reflected pressure waves was higher in girls than in boys because ejection duration was longer and the time of reflected pressure waves from the periphery was shorter in girls.

Why is it important?
Our findings add information regarding the sexual dimorphism intrinsic to human central hemodynamics. Clinicians should benefit from this knowledge since it helps with early identification of cardiovascular risk profile.
Perspectives
We hope this article reaches the target audience. Although we recognize that this subject is still little known among clinicians, we expect that the plain language we try to use and the clarity of physiological reasoning make reading attractive to them.
