Uterine Artery Diastolic Notching & Apelin-13 and 36

April 25, 2024 updated by: ibrahim kale, Umraniye Education and Research Hospital

Investigation of the Relationship Between Uterine Artery Doppler Diastolic Notching and Serum Apelin-13 and Apelin-36 Concentrations Between the 11th and 14th Weeks of Pregnancy

This study was conducted to investigate the relationship between diastolic notching on uterine artery Doppler and serum apelin-13 and 36 concentrations between 11 and 14 weeks of gestation.

Detailed Description

Apelin-13 and apelin-36, which provide vasodilatation through a nitric oxide-dependent mechanism, also play a role in trophoblasts' survival, proliferation, and migration.

Based on this, we aimed to investigate serum apelin-13 and apelin-36 concentrations in pregnant women with and without diastolic notch on uterine artery Doppler between the 11th and 14th weeks of pregnancy.

We hypothesized that apelin-13 and apelin-36 might be associated with the formation of diastolic notch in uterine artery Doppler and serum apelin-13 and apelin-36 concentrations would be lower in the group with a notch in the uterine artery Doppler than in the group without a notch.
