Comparison of Left Ventricular Ejection Fraction in Heart Failure Patients on Echocardiography, Cardiac Magnetic Resonance Imaging and Single Photon Emission Computed Tomography

Objective: To compare the left ventricular ejection fraction on echocardiograph, cardiac magnetic resonance imaging and single-photon emission computed tomography scan in heart failure patients.
 Study Design: This was a prospective cross-sectional study.
 Place Duration of Study: Tertiary Cardiac Care Center Rawalpindi, Pakistan, from Nov 2021 to Apr 2022.
 Methodology: study conducted November April 2022 at tertiary care center Rawalpindi. Thirty (n=30) patients either gender with reduced were selected by consecutive sampling technique analyzed quantify their (LVEF) using Echo, CMR SPECT scan. All three modalities used measure LVEF these compared accordingly.
 Results: The measured Magnetic Resonance Imaging, Single Photon Emission Computed Tomography Scan Echocardiography range 15% 67%. mean 37.2±14.2 CMR, 37.17±14.1 38±12.3 Echo. determined slightly lower while that higher. p-value modalities, however, indicated statistically difference (p-value <0.05).
 Conclusion: Although literature shows diversity results is considered standard reference for assessment when interpreted an expert observer. We our found all are complimentary each other can be interchangeably depending upon availability equipment reporting expertise observers.
