Why the study?

Does two-dimensional echocardiography and a combined method improve the accuracy of left ventricular volume and stroke volume measurements compared to one-dimensional echocardiography in male athletes and untrained subjects?

Population

108 males (40 untrained subjects and 68 endurance athletes)

Comparison

Two-dimensional echocardiography and a combined… vs One-dimensional echocardiography

Design

Cross-sectional

Implication

Two-dimensional and combined echocardiographic methods provide highly accurate measurements of left ventricular volume and stroke volume, correlating strongly with maximum oxygen pulse.

Key Points

To assess the accuracy of one-dimensional, two-dimensional, and combined echocardiographic techniques for determining left ventricular volumes and stroke volume in trained and untrained individuals.
Measured left ventricular end-diastolic volume (EDV), total volume (TDV), and stroke volume (SV) in 40 untrained males and 68 male endurance athletes.
Compared 1D echocardiography, 2D echocardiography, and a combined method against ergometric maximum oxygen pulse (max O2-P) and radiographic heart volume (HV).
Two-dimensional echocardiography and the combined method significantly improved the accuracy of EDV, TDV, and SV estimations compared with one-dimensional echocardiography.
The combined total volume method (TDV2) yielded the highest correlation with maximum oxygen pulse (r = 0.8738), matching the correlation between radiographic heart volume and maximum oxygen pulse (r = 0.8665).

Population

108 males (40 untrained subjects and 68 endurance athletes)

Intervention

Two-dimensional echocardiography and a combined method for measuring left ventricular volume (EDV, TDV) and stroke volume (SV)

Comparator

Outcome

Accuracy of volume and stroke volume measurements (correlation to ergometrically determined maximum oxygen pulse [max O2-P] and radiographic heart volume [HV])surrogate

Two-dimensional and combined echocardiographic methods provide highly accurate measurements of left ventricular volume and stroke volume, correlating strongly with maximum oxygen pulse.
