Hypertrophic cardiomyopathy - Average percent difference in left ventricular peak systolic apical rotation (Range: Control; 3.6 to 19.5, Patients; 4.1 to 12 degrees),[21, 31–33, 56] peak systolic basal rotation (Range: Control; -3.4 to −8.1, Patients; -3.2 to −6.6 degrees),[21, 31–33, 56] peak systolic twist (Range: Control; 6.6 to 22.6, Patients; 7 to 20 degrees)[21, 23, 32, 33, 55, 56], untwisting at 5% diastole (Range: Control; 17 to 21, Patients; 10 to 12 percent),[32, 56] untwisting at 10% diastole (Range: Control; 35 to 37, Patients; 23 to 25 percent),[32, 56] untwisting at 15% diastole (Range: Control; 49 to 50, Patients; 36 to 39 percent)[32, 56] and time to peak untwist (Range: Control; 14.6 to 111, Patients; 22.8 to 153% of systole (lower values normalized for diastolic duration)[55, 56] between those with hypertrophic cardiomyopathy and healthy controls as reported in existing articles . Diastolic parameters denoted by empty boxes. Note that one author used the same population in two publications.[31, 54] Therefore only one article was used in the percentage difference calculations.[31] Systolic parameters denoted by red filled boxes. Diastolic parameters denoted by empty boxes.
