Abstract

Introduction: The correlation between right and left ventricular ejection fractions (RVEF and LVEF, respectively) has been studied in only a small number of patients with a marked decrease in RVEF and LVEF. The aim of the present study was to compare LVEF and RVEF in patients with ischemic heart disease. RVEF and LVEF were measured by Cardiovascular Magnetic Resonance (CMR) imaging.
Materials and Methods: This observational study was done in Ghaem general hospital in 2014. LVEF and RVEF were measured in a series of 33 patients with ischemic heart disease, undergoing CMR for the evaluation of myocardial viability. The correlation between RVEF and LVEF in patients with ischemic heart disease was studied, using Pearson product-moment correlation coefficient analysis. This study was done in Ghaem general hospital in 2014 with simple sapling.
Results: Right ventricular end diastolic volume (186.33±58.90) and left ventricular end diastolic volume (121.72±61.64) were significantly correlated (r=0.223, P=0.005). Moreover, there was a significant correlation between right ventricular end systolic volume (88.18±40.90) and left ventricular end systolic volume (140.96±35.33) (r=0.329, P=0.000). The most significant association was observed between RVEF and LVEF (r=0.913, P=0.000).
Conclusion: Based on the findings, RVEF and LVEF were significantly correlated in patients with ischemic heart disease, although this association was not always present in all cardiac patients. The cause of this discrepancy is still unknown.
