Hypothesis
The study aims to assess the correlation of left ventricular mass between transthoracic echocardiography and 64-slice multidetector computed tomography.
Conclusion
Both imaging methods are consistent and accurate, but there is a slight overestimation of left ventricular mass by echocardiography compared to computed tomography.
Supporting Evidence
- The intraclass correlation coefficient was 0.67, indicating moderate agreement between the two methods.
- The concordance correlation coefficient was also 0.67, supporting the accuracy of the measurements.
- The Passing-Bablock regression showed no systematic error but indicated a proportional error.
Takeaway
The study looked at two ways to measure heart size and found they mostly agree, but one method might show a slightly bigger size than the other.
Methodology
A prospective cohort study measuring left ventricular mass using both TTE and MDCT in a blind manner.
Limitations
The study may have limitations related to the quality of the echocardiography window.
