(1) The width of AWM-TRA was decreased significantly only in DAT.
(2) Depressed RVF and reduced AWM were observed in 26 (35%) (Group A); depressed RVF and normal AWM were found in 20 (27%) (Group B); reduced AWM and normal RVF in 10 (13%) (Group C); and normal RVF and AWM in 19 (25%) (Group D).
(3) The patients were divided into four groups based on the right ventricular function (RVF) and anterior wall motion (AWM) of the left ventricle by scan at the time of admission.
(4) Of the three definitions of abnormality used in method A, the best correlation was achieved between area at risk and less than 10% inward endocardial excursion and was expressed by the following polynomial regression: AWM = -0.01 AR2 + 1.5 AR -0.14 (r = 0.92, p less than 0.001, SEE = 1.7%).
(5) The abnormal wall motion (AWM) score was calculated, and the cardiac events (death, reinfarction, severe ventricular arrhythmia or congestive heart failure) after discharge were recorded.
(6) When absolute values of each AWM width were compared between right and left sides, there were no differences in AWM and AWM-TER.
(7) The width of AWM-TRA of the left side was tended to decrease with age.
(8) When the data were examined in relation to the age of the myocardial infarct, the echocardiographic %AWM appeared to overestimate the autopsy infarct size (by percent infarct volume) in the recent infarct group (n = 6), and underestimate the extent in the old infarct group (n = 13).
(9) Similarly, a good correlation was found for the percent abnormal wall motion and the autopsy percent endocardial surface area overlying infarction (%AWM = 0.89 X infarct area - 0.9; r = .89, p = .0001).
(10) I asked Dr Brendan Nelson following his AWM directorship appointment – ‘When will the AWM acknowledge the frontier conflicts and put a memorial to Aboriginal people on Anzac parade?’ Dr Nelson was adamant that the AWM does not acknowledge the ‘frontier conflicts’ as war and won’t acknowledge Aboriginal participation in war,” Mortimer said.
(11) Normalized values of AWM, AWM-TER, AWM-TRA showed a similar results as that of the absolute values.
(12) The best linear correlation between area at risk (AR) and abnormal wall motion (AWM) was achieved using method B and expressed by the following linear regression: AWM = 0.92 AR + 3.0 (r = 0.92, p less than 0.0001, SEE = 1.7%).
(13) The endocardial surface area (ESA) and the area of abnormal wall motion (AWM) were reconstructed from the echocardiographic data using a previously reported technique for quantitatively mapping the ESA and extent of AWM.
(14) The width of AWM was not correlated with age, but the width of AWM-TER showed a significant decline in the left (r = -0.36, p = 0.04) and non-significant trend to decline in the right side (r = -0.33, p = 0.07).
(15) Measurements from the echocardiograms were used to construct maps of the left ventricular endocardial surface from which the endocardial surface area index (ESAi) and the percent of the endocardial surface area involved by abnormal wall motion (%AWM) were calculated.
(16) However, AWM-TRA of the right side was significantly wider than that of the left side (t = 4.28, p less than 0.001).
(17) The widths of the anterior white matter bundle (AWM) and the interhemispheric (AWM-TER) and intrahemispheric (AWM-TRA) bundles at the level of the foramen of Monro on horizontal inversion recovery MRI scans were measured in 17 patients with dementia of Alzheimer type (DAT), 16 patients with multi-infarct dementia (MID) and 47 age-matched normal subjects (NOR).
(18) Asked if Nelson would consider depicting frontier conflict in the memorial, an AWM spokeswoman said the memorial “holds a rich collection of material related to Indigenous servicemen and women from the first world war”.
(19) The endocardial surface area therefore expands immediately after coronary occlusion and the magnitude of this process is primarily related to the site (anteroapical) rather than to the extent of AWM.
(20) Regional function, as represented by the area of AWM, was also improved but the timing of the improvement was related to the location and size of the infarction.
