This research study is designed to evaluate the accuracy of the techniques that are used to analyze heart function. The main purpose of this study is to analyze and compare three different methods of assessment of regional and overall heart function.
The purpose of the present study is to establish the reproducibility and to validate gated blood pool SPECT imaging with application of attenuation correction (ACGBS) in evaluation of left ventricular regional and global function and volumes, by direct comparison with Equilibrium Radionuclide Angiocardiography (ERNA) and 3-dimensional ECHO (3DE).
5,701 studies on the registry are indexed under Heart Failure; 1,220 are open to participants now.
This study's enrollment of 30 is below the median of 200 across 1,679 observational studies indexed under Heart Failure.

Each patient scheduled to undergo clinically requested ERNA imaging for assessment of LV function in the Yale University Cardiovascular Nuclear Imaging Laboratory will be an eligible candidate and will be asked to participate. Based on our referral pattern it will include both patients with cardiac and non-cardiac disease, the later usually consist of patients undergoing chemotherapy.
Exclusion Criteria:
Patients being referred for the routine Equilibrium Radionuclide Angiocardiography (ERNA) for assessment of their left ventricular function will be asked to participate in the study. All patients will be asked to sign the consent form. Patients will be given a choice to participate in either or both studies (i.e. ERNA plus ACGBS or ERNA plus ACGBS and 3 DE).
2D echo provides a good estimate of regional LV function but if done with 3D analysis can provide a good estimate of global LV function and volumes. The quality of 3DE can be further improved by use of IV contrast which is FDA approved.
