title: [Correlations between the patterns--dynamic--of regional contraction and the ECG-enzymatic-clinical signs of myocardial infarction (author's transl)].
abstract: 60 patients with clinical signs of coronary artery disease who had a hemodynamic examination were studied. The study of the regional dynamics using the deformation as a vectorial time-dependent parameter and the pressure-length loops, was carried out on a total of 420 parietal regions of the left ventricle: the basal ventriculography, the post-extrasystolic potentiation and the ventriculography after nitroglycerin were evaluated. The dynamic regional pattern was correlated with clinical-enzimatic signs of necrosis in the electrocardiogram. The possibility of correlating signs of necrosis with particular patterns of hypokinesia, akinesia, dyskinesia which differ from corresponding "static" forms of asynergy in active pressure development and deformation (even in a brief systolic interval) seems to confirm the physiopathologic interpretation of the regional phenomenon based on the ratio between viable not viable myocardium -- as primary cause.
