The aim of this study was to evaluate the influence of polycystic ovary syndrome (PCOS) and obesity on vascular parameters related to early atherosclerosis (VP-EA) [brachial flow-mediated dilation (FMD), carotid intima-media thickness (CIMT) and carotid arterial compliance (CAC)] in women with minor cardiovascular risk factors (CVRFs). Twenty-five young women with PCOS and 23 eumenorrheic women matched for body mass index (BMI) were studied. The women were subdivided according to BMI and PCOS status, and comparisons were done between PCOS and Control group, regardless of BMI, and between Obese and Lean group, regardless of the presence of PCOS. Insulin resistance was higher in PCOS-group than in control-group and in obese-group than in lean-group. The median of all VP-EA evaluated were similar between PCOS-group and Control-group [FMD: 6.6 versus 8.4% (p = NS); CIMT: 48.0 versus 47.0 mm.10-2 (p = NS); CAC: 6.2 versus 5.6N-1.m4.10-10 (p = NS)] and between obese-group and lean-group [FMD: 7.8 versus 6.6% (p = NS); CIMT: 48.0 versus 47.0 mm.10-2 (p = NS); CAC: 5.7 versus 6.3N-1.m4.10-10 (p = NS)]. These results suggest that PCOS and obesity do not affect VP-EA in women with minor CVRFs.
本研究旨在评估多囊卵巢综合征(PCOS)和肥胖对伴有轻微心血管危险因素(CVRFs)女性早期动脉粥样硬化相关血管参数(VP-EA)[肱动脉血流介导的扩张(FMD)、颈动脉内膜中层厚度(CIMT)和颈动脉顺应性(CAC)]的影响。研究纳入了 25 名患有 PCOS 的年轻女性和 23 名体质量指数(BMI)匹配的正常月经周期女性。根据 BMI 和 PCOS 状况对女性进行分组,并比较了 PCOS 组和对照组(无论 BMI 如何)、肥胖组和瘦弱组(无论是否存在 PCOS)之间的差异。与对照组和瘦弱组相比,PCOS 组的胰岛素抵抗更高。PCOS 组与对照组之间[FMD:6.6%比 8.4%(p = NS);CIMT:48.0 毫米比 47.0 毫米.10-2(p = NS);CAC:6.2 比 5.6N-1.m4.10-10(p = NS)]和肥胖组与瘦弱组之间[FMD:7.8%比 6.6%(p = NS);CIMT:48.0 毫米比 47.0 毫米.10-2(p = NS);CAC:5.7 比 6.3N-1.m4.10-10(p = NS)]所有评估的 VP-EA 中位数均无显著差异。这些结果表明,PCOS 和肥胖并不影响伴有轻微 CVRFs 的女性的 VP-EA。
