Abstract

Objective: To assess cardiac flow parameters in patients with polycystic ovary syndrome (PCOS).Design: A prospective case-control study. Setting: University-based hospital.Patient(s): Thirty consecutive patients with PCOS were enrolled. Thirty women with regular menstrual cycles served as the controls.Intervention(s): Systolic and diastolic function parameters were assessed by standard two-dimensional and M-mode echocardiography. Insulin sensitivity was evaluated by a standard 75-g oral glucose tolerance test and area-under-curve insulin analysis. Serum hormones, lipid profile, homocysteine, vitamin B12, folate, fibrinogen, uric acid, and plasminogen activator inhibitor-I concentrations were measured. Main Outcome Measure(s): Systolic and diastolic function parameters, insulin sensitivity and serum homocysteine levels. Result(s): The mean serum homocysteine and uric acid concentrations were significantly higher in the PCOS group. Patients with PCOS had significant hyperinsulinemia. All systolic function parameters were comparable between the two groups. However, patients with PCOS had significantly lower peak mitral flow velocity in early diastole and significantly lower ratio between the early and late peak mitral flow velocities and also had significantly longer isovolumic relaxation time, reflecting a trend for nonrestrictive-type diastolic dysfunction. The area-under-curve insulin correlated positively with peak mitral flow velocity in late diastole (r = 0.375). The mean cholesterol/high-density lipoprotein ratio correlated negatively with mean mitral flow velocity in early diastole (E) peak (r = -0.474). The mean fasting insulin level correlated negatively with mean E/A ratio (r = -0.387). Conclusion(s): Diastolic dysfunction and increased serum homocysteine concentrations may contribute to increased cardiovascular disease risk in patients with PCOS.
