BACKGROUND AND OBJECTIVE: Correlation between right and left ventricular ejection fraction (RVEF, LVEF) has been studied in only a small number of patients with a marked decrease in RVEF and LVEF. The goal of the present study was to compare LVEF and RVEF in a large population with low and normal ejection fractions (EFs) measured by blood pool scintigraphy. METHODS: A series of 152 patients who underwent LVEF measurement for a clinical indication also underwent simultaneous measurement of the RVEF. The correlation between RVEF and LVEF in patients with or without depressed EF was studied using Pearson's regression analysis. RESULTS: Although RVEF and LVEF were significantly correlated in an S curve mathematical function, the correlation was weak when the entire cohort was considered (r=0.32; P<0.001). However, when patients with lower EF (LVEF and RVEF less than 50%) were considered, the correlation was stronger (r=0.41; P<0.001), and in patients with normal biventricular EF (LVEF and RVEF 50% or greater), the correlation was completely absent (r=0.001; P=0.86). The strongest correlation between RVEF and LVEF occurred in patients with LVEF and RVEF less than 30% (r=0.75, P=0.03). CONCLUSION: Patients with decreased EF have highest correlation between LVEF and RVEF in comparison with no correlation in patients with normal EF. The cause of this discrepancy is not known. |
