Measurement of ejection fraction in the elderly
Age and Ageing
|August 1, 1980
Summary
This study validates a simple, non-invasive radionuclide method for measuring ejection fraction in elderly patients. The technique shows high reproducibility and correlates well with other measures, proving valuable for assessing drug effects on the heart.
Area of Science:
- Cardiology
- Nuclear Medicine
- Geriatric Medicine
Background:
- Assessing cardiac function, specifically ejection fraction, is crucial in elderly patients.
- Non-invasive and accurate methods are needed for monitoring cardiovascular health and treatment efficacy.
Purpose of the Study:
- To evaluate a simple, virtually non-invasive radionuclide method for measuring ejection fraction.
- To assess the reproducibility and clinical relevance of this method in elderly individuals.
Main Methods:
- A radionuclide imaging technique was employed to measure ejection fraction.
- The study included 60 elderly patients, with duplicate measurements performed for reproducibility analysis.
Main Results:
- The mean difference between duplicate ejection fraction measurements was 4.9%.
- The obtained ejection fraction values demonstrated good correlation with established methods and systolic time intervals.
Conclusions:
- The radionuclide method for ejection fraction measurement is reliable and reproducible in elderly patients.
- This technique is particularly useful for evaluating the impact of cardiac medications on myocardial function.
