Fig. 6 — Application of the heart-to-mediastinum ratio (HMR) in a risk model. A sample plot of 5-year cardiac mortality risk is shown in a 54-year-old man with chronic heart failure, which is expressed as a function of HMR. This calculation is based on conditions of NYHA class III, left ventricular ejection fraction of 20%, and HMR of 1.4, and estimated mortality is 56%/5 years (purple dot) [45, 46]
