[Differences in reference values in 2-dimensional echocardiography in men and women]

Area of Science:

• Cardiology
• Medical Imaging
• Human Physiology

Context:

• Establishing reference values for echocardiographic measurements is crucial for accurate diagnosis.
• Two-dimensional echocardiography is a key non-invasive imaging technique in cardiology.
• Previous studies may not have adequately accounted for sex-based variations in cardiac dimensions.

Purpose:

• To establish reference standards for two-dimensional echocardiography measurements in a healthy adult population.
• To investigate potential sex-based differences in cardiac dimensions.
• To determine the reliability of various echocardiographic parameters.

Summary:

• This study examined 126 healthy blood donors (90 men, 36 women) to define two-dimensional echocardiography standards.
• Measurements included left ventricle, interventricular septum, posterior wall, left atrium, aorta, and right ventricle dimensions.
• Men exhibited significantly larger dimensions in several parameters compared to women, emphasizing the need for sex-specific reference values.

Impact:

• Provides essential normative data for interpreting echocardiographic findings.
• Highlights the necessity of incorporating sex-specific parameters in clinical practice and research.
• Contributes to improved accuracy in diagnosing and managing cardiovascular conditions.
