Myocardial triglycerides (TGs) and systolic function in humans. In vivo evaluation by localised proton spectroscopy and cardiac imaging. a) Selection of volume of interest in the ventricular septum and in the left ventricular (LV) wall with corresponding spectra. Spectrum from septum displays single resonance from myocardial TG. Spectrum from LV wall contains additional resonance from epicardial fat. Scale bar = 2 cm. b) Myocardial TG is inversely correlated with the regional systolic function measured as septal thickening. Normal range of septal thickening is indicated by the shaded area. c) Concentric remodelling of LV with increased deposits of myocardial TGs documented by the relationship of myocardial lipids and concentricity index measured as a ratio of LV mass and volume. Normal levels of concentricity index are indicated by the shaded area. Reproduced and modified from [42] with permission from the publisher.
