Ikram Mizrak “Aortic distensibility is equal in prepubertal girls and boys"

Hi, my name is Jannik Pallisgaard, and I am back with “2 minutes @CopCard.” Today I am back with a study from Ikram Mizrak and colleagues entitled “Aortic distensibility is equal in prepubertal girls and boys and increases with puberty in girls.” In this study, they determined conductance artery compliance and cardiac function by MRI in 150 healthy children, 50-50 boys and girls aged 7-10 years Data showed that, respectfully, the ascending and descending aortic distensibility were higher in girls with a crude mean difference of 1.11 and 1.10. These differences disappeared after adjustment for pubertal status and other identified potential predictors Systolic and diastolic blood pressure, cardiac output, left ventricle systolic function, and total peripheral resistance did not differ between the sexes. In girls, heart rate was 7 bpm higher, whereas pulse pressure, LV end-diastolic volume index, and stroke volume were lower. So, in conclusion, prepubertal girls and boys have equal conductance artery function. Thus, the well-known sex difference in adult conductance seems to develop after the onset of puberty This is Jannik Pallisgaard. Thank you for watching “2 Minutes @CopCard”.
