Abstract:
Objective: To observe the value of vascular echo tracking (ET) in evaluating early carotid atherosclerosis in patients with polycystic ovary syndrome complicated with insulin resistance (PCOS-IR). Methods: According to the carotid intima-media thickness (CIMT), totally 90 patients with PCOS-IR were divided into PCOS-IR-A group (CIMT<0.10 cm, n=52) and PCOS-IR-B group (CIMT 0.10-0.15 cm, n=38). Meanwhile, 90 age-matched healthy women were enrolled as control group. The stiffness degree (β), pressure-strain elasticity modulus (Ep), single point pulse wave conduction velocity (PWVβ), augmentation index (AI) and arteria compliance (AC) of common carotid artery were measured with ET and compared among 3 groups. Results: There were significant differences of β, Ep, PWVβ and AC among PCOS-IR-A group, PCOS-IR-B group and control group (all P<0.05), while there was no significant difference of AI (P=0.250). β, Ep and PWVβ in PCOS-IR-B group were higher, while AC was lower than those in control group and PCOS-IR-A group. β, Ep and PWVβ in PCOS-IR-A group were higher, while AC was lower than those in control group (all P<0.05). Conclusion: ET technique can be used to quantitatively evaluate the elastic parameters of carotid artery. Vascular elastic dysfunction in early carotid atherosclerosis in patients with PCOS-IR can be early detected, therefore providing important evidences for early clinical intervention of PCOS-IR.
