Differential characteristics of LV geometry between systolic and diastolic HF (modified from Zile MR [49]).
| Characteristic | Systolic HF | Diastolic HF |
| LV volume | ↑ ↑↑ |
N (o ↓) |
| LV mass | ↑ | ↑ |
| LV geometry | Eccentric | Concentric |
| Cardiomyocites | ↑ Length | ↑ Diameter |
| Extracellular Matrix | ↓(o ↑ o N) Collagen | ↑↑ Collagen |
HF = heart failure, LV = left ventricular, N = normal
