Epicardial Adipose Tissue Thickness in Polycystic Ovary Syndrome (PCOS)

June 10, 2011 updated by: Gulhane School of Medicine

The Relationship Between Epicardial Adipose Tissue Thickness, Insulin Resistance and Plasma Adiponectin Concentrations In Patients With Polycystic Ovary Syndrome

The aim of the present study was to search whether epicardial adipose tissue thickness, a predictor of increased cardiovascular risk, increases in PCOS patients or not and, if it does, to analyze the relationship of EATT with insulin resistance, adiponectin and biochemical and anthropometric parameters.

Detailed Description

Context: Polycystic ovary syndrome (PCOS) is characterized with chronic oligo/unovulations, hyperandrogenism and insulin resistance. Insulin resistance is mostly attributed to visceral adipose tissue. Epicardial adipose tissue thickness (EATT) is in close relation with atherosclerotic coronary heart disease and its importance in PCOS is not determined yet. Thus, we aimed to clarify EATT in patients with PCOS and compare with healthy matched controls. In addition we searched plasma adiponectin levels to clarify its relationship with EATT in patients with PCOS.

Settings: EATT was determined by echocardiography. Insulin resistance is calculated as HOMA-IR and plasma adiponectin levels were determined with ELISA radioimmunoassay at Gülhane School of Medicine, Ankara, Turkey.

Patients: Patients with PCOS and healthy controls who were similar in body mass index (BMI) and age (p=0.118, p=0.081, respectively) were enrolled in the study after having their written consents.

Results: Mean EATT and HOMA-IR levels were significantly higher (p=0.001, p=0.001, respectively) while plasma adiponectin concentrations were significantly lower (p=0.0032) in patients with PCOS than controls. There was no correlation between plasma adiponectin levels and EATT in subjects (p=0.824). EATT levels were in positive correlation with HOMA-IR, plasma triglyceride concentrations and body mass index (BMI) (p=0.022, p=0.027, p=0.022, respectively). HOMA-IR, triglyceride levels, HDL-Cholesterol, LH/FSH ratio were most powerful determinants of EATT in logistic regression modeling (p=0.016, p=0.021, p=0.049, p=0.039, respectively).

Conclusion: EATT is increased in patients with PCOS in concordance with HOMA-IR level and these findings may reflect the increased risk for atherosclerotic cardiovascular disease in this particular patient group.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 44 years (Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Mean EATT and HOMA-IR levels were significantly higher (p=0.001, p=0.001, respectively) while plasma adiponectin concentrations were significantly lower (p=0.0032) in patients with PCOS than controls.
Time Frame: 1 year
june 2009-june 2010
1 year
HOMA-IR, triglyceride levels, HDL-Cholesterol, LH/FSH ratio were most powerful determinants of EATT in logistic regression modeling (p=0.016, p=0.021, p=0.049, p=0.039, respectively)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
January 1, 2009

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
