| Popis: | Objective: To assess the impact of regional left ventricular curvature in patients with an acute anterior myocardial infarction on ventricular volume.Methods: Left ventricular curvature was calculated at 100 points from apical four chamber echocardiograms of 68 patients with an acute anterior wall infarction. Curvature at any point of the contour was defined as the reciprocal of the radius of the circle that intersects that point tangentially and was independent of volume and geometric assumptions. Curvature, volume and shape of the patient group was compared with these measurements in 20 normal volunteers.Results: Diastolic curvature differed at the borderzone of the infarct and the apical area. In the basal septal area (point 9–18) mean curvature was lower in the patient group (0.1±2.7 versus 2.1±0.7; p |
