[Reliability of an echocardiographic evaluation of the left ventricular pumping function in ischemic heart disease]
Insights
Echocardiography reliably assesses left ventricular pump function. Calculations using specific formulas, like cube, Forteen, and Teiholz, enhance accuracy in evaluating cardiac performance.
Area of Science:
- Cardiovascular medicine
- Medical imaging
- Cardiac physiology
Background:
- Left ventricular (LV) pump function is crucial for cardiac health.
- Accurate assessment of LV function is vital for diagnosing and managing heart conditions.
- Echocardiography is a non-invasive imaging technique used to evaluate cardiac structure and function.
Purpose of the Study:
- To compare the reliability of echocardiography with angiography in determining left ventricular pump indices.
- To evaluate the accuracy of different echocardiographic formulas for calculating LV pump function.
Main Methods:
- Simultaneous angiographic and echocardiographic measurements were performed in 38 male patients (aged 34-58).
- Left ventricular pump indices were calculated using three echocardiographic formulas: cube, Forteen, and Teiholz.
- Computer analysis was employed for data processing and correlation coefficient derivation.
Main Results:
- High correlation coefficients were found between echocardiographic and angiographic methods.
- Echocardiography demonstrated high reliability in assessing left ventricular pump function.
- The accuracy of echocardiographic calculations was particularly high when formulas were selected based on diastolic LV measurements.
Conclusions:
- Echocardiography is a reliable tool for evaluating left ventricular pump function.
- Selective use of specific echocardiographic formulas (cube, Forteen, Teiholz) improves accuracy.
- Echocardiography offers a valuable, non-invasive alternative to angiography for assessing LV pump performance.
Abstract:
Almost simultaneous angiographic and echocardiographic determination of the pump indices of left ventricle was performed to 38 male patients, aged 34 to 58. A special computer was used for the processing of the data. The echocardiographic indices were calculated by three formulae: cube, Forteen and Teiholz . Coefficients of correlation were derived between the two methods, confirming a relatively high reliability of echocardiography in the evaluation of left ventricular pump function, particularly if the calculations were selectively performed according to one of the three formulae, depending on the value of diastolic measure of left ventricle.
