Introduction:

Relatives of women with polycystic ovary syndrome have been show to present a higher frequency of cardiovascular risk factors, such as insulin resistance, type 2 diabetes mellitus, dyslipidemia and arterial hypertension. Therefore, these people have a higher risk for developing cardiovascular disease.

Objective:

To determine the frequency of subclinical cardiovascular disease in first-degree relatives of women with and without polycystic ovary syndrome and its relationship with insulin resistance.

Methods:

A cross-sectional and descriptive study was carried out with 36 first-degree relatives of women with polycystic ovary syndrome and with the same number of relatives of women without the disease. None of the members of both groups had a history of diabetes mellitus, prediabetes, dyslipidemia, high blood pressure, or obesity. To carry out the comparison of the results of the tests carried out, they were matched at a 1: 1 ratio, by age ± 5 years, relationship, sex and body mass index.

Results:

There were 21 relatives with subclinical cardiovascular disease, 71.4% of which belonged to the study group, why 28.6% belonged to the control group (P < 0.05). Of the total family members of the study group, with insulin resistance, 65.0% had subclinical cardiovascular disease. In the control group, with normal fasting insulinemia, none has subclinical cardiovascular disease.

Conclusions:

Subclinical cardiovascular disease is more frequent in the relatives of women with polycystic ovary syndrome, while insulin resistance is significantly associated with this condition in both groups.
