Relationship between right and left ventricle function in subjects free of cardiovascular diseases: a population-based MRI study

Right (RV) and left ventricular (LV) volumetric measurements by cardiac magnetic resonance imaging (MRI) are established for assessing systolic and diastolic function, but the role of MRI-derived lung volumes in LV function remains unclear. This study investigated the relationship between RV and LV function, considering lung volumes. In the KORA-MRI cohort, 361 subjects underwent 3 T whole-body MRI. Cardiac functional parameters were measured from cine-steady-state free precession sequences using cvi42. Lung volumes were derived semi-automatically with an in-house algorithm. Linear regression analyses assessed RV-LV relationships, adjusted for age, sex, cardiovascular risk factors, and lung volumes. Among 361 subjects (mean age 56.1 ± 9.1 years; 43% women), RV end-diastolic volume was positively associated with LV end-diastolic (
