Brief Summary:
To examine whether serum androgens measured earlier in life and variation in genes related to androgen synthesis metabolism and signaling are associated with early-onset subclinical coronary atherosclerosis in young adult women from the community
Detailed Description:
BACKGROUND
Polycystic ovary syndrome PCOS is denoted by hyperandrogenism and symptoms of ovulation dysfunction eg infertility oligomenorrhea Women who are diagnosed with PCOS represent the more extreme end of abnormal ovarian function While PCOS is rare approximately 20 percent of women are expected to have subclinical polycystic ovaries identified by sonogram Factors that are associated with PCOS insulin resistance and dyslipidemia are also risk factors for coronary artery disease and there is evidence to suggest that women with PCOS are more likely to experience coronary artery disease This raises the question are subclinical cases of polycystic ovaries at increased risk of coronary artery disease
The study is ancillary to the the Coronary Artery Risk Development in Young Adults CARDIA Study a large cohort study supported by the NHLBI The CARDIA population provides a unique opportunity to explore these associations because there is a 15-year period of risk factor ascertainment in this population including stored blood DNA specimens from which serum androgens and relevant genetic markers can be ascertained In addition all participants will have coronary artery calcium CAC determinations at the year 15 exam In the ancillary study an additional year 16 visit will occur for the purpose of obtaining a trans vaginal ultrasound determination TVUS so as to obtain clinical evidence of hyperandrogenism and look at the joint effects of the clinical evidence and serum markers as predictors of CAC The study is in response to an initiative on Ancillary Studies in Heart Lung and Blood Disease Trials released in June 2000
DESIGN NARRATIVE
The ancillary study in year 16 of CARDIA will recall 1200 women who received a coronary artery calcification CAC determination in year 15 These women will have an additional blood draw three to 10 days after their last menstrual period will have a questionnaire administered to them regarding clinical symptoms of PCOS polycystic ovarian syndrome and other aspects of hyperandrogenism Two principal analyses will be performed The first is a longitudinal analysis using year 2 and year 10 data to use serum markers of hyperandrogenism and genetic markers from DNA samples as predictors of CAC which is defined as present absent and is determined at the year 15 examination The principal method of analysis will be logistic regression An additional analysis will relate androgen levels at year 2 to lipid levels and other coronary risk factors ascertained at year 2 7 10 and 15
