Effect of increased body mass index on accuracy of two-dimensional echocardiography for measurement of left ventricular volume, ejection fraction, and mass.
We used 2- and 3-dimensional echocardiography to determine left ventricular volume, mass, and ejection fraction in overweight (body mass index [BMI] > or = 25 kg/m2), obese (BMI > or = 30 kg/m2), and control (BMI < 25 kg/m2) subjects. Compared with corresponding magnetic resonance imaging measurements, 3-dimensional echocardiography is more accurate than 2-dimensional echocardiography in all patients, but particularly in overweight and obese subjects.
