Heart failure - Average percent difference in left ventricular peak systolic apical rotation (Range: Control; 3.3 to 9.4, Patients; 1 to 2.4 degrees),[43, 64, 65] peak systolic basal rotation (Range: Control; -6.1 to −9, Patients; -3.3 to −3.5 degrees) [43, 64, 65] and peak systolic twist (Range: Control; 14 to 16.2, Patients; 4.8 to 6.8 degrees) [20, 63, 64] between those with heart failure and healthy controls as reported in existing articles. Systolic parameters denoted by red filled boxes.
