Left ventricular function in patients with polycystic ovary syndrome: a Doppler echocardiographic study

Area of Science:

• Cardiology
• Endocrinology
• Reproductive Medicine

Background:

• Polycystic ovary syndrome (PCOS) is a common endocrine disorder associated with increased cardiovascular risk factors.
• Understanding the cardiac implications of PCOS is crucial for comprehensive patient management.

Purpose of the Study:

• To compare echocardiographic profiles of patients with PCOS to healthy controls.
• To assess cardiac function using conventional echocardiography and tissue Doppler imaging.

Main Methods:

• 26 untreated PCOS patients and 24 matched healthy controls were studied.
• Conventional echocardiography, M-mode, and color Doppler M-mode were employed.
• Tissue Doppler imaging of the mitral annulus and basal wall was performed.

Main Results:

• No significant differences were observed in ejection fraction, mitral E/A ratio, or relaxation times between groups.
• Pulmonary venous flow, transmitral valve flows, and left ventricular inflow propagation velocities (Vp) were similar.
• Tissue Doppler imaging revealed comparable cardiac function in PCOS patients and controls.

Conclusions:

• Conventional and tissue Doppler echocardiography show no significant differences in cardiac function measures between PCOS patients and healthy subjects.
• This suggests that standard echocardiographic parameters may not detect subclinical cardiac dysfunction in PCOS patients at this stage.
