Aim. The aim of the study is to verify that the left ventricle systolic and diastolic dysfunction have two diverse localization of the segmentary contractility alteration.
Methods. The gated equilibrium ventriculography was used to explore the left ventricle segmentary contractility in the left anterior oblique view in 3 patients groups: group 1 with systolic dysfunction (10 patients); group 2 with diastolic dysfunction (15 patients); group 3 the control patients (27 patients). The global ejection fraction and the peak filling rate, that the same gated equilibrium ventriculography furnishes, were used to differentiate the groups.
Results. A discriminant analysis according to Fisher was executed to see if the isocontours and the regional ejection in the 4 sector tested for the analysis (posterolateral; inferolateral; apical septal; basal septal) that the gated equilibrium ventriculography furnishes, classified the patients in the groups and they classified correctly the 80% of the cases. The analysis of the mean excursion with the standard deviation showed that the systolic dysfunction joined with a basal septal and apical septal hypokinesis and the diastolic dysfunction joined with a posterolateral and inferolateral hypokinesis.
Conclusion. In this way the segmentary contractility diverse topography that is joined to systolic and diastolic dysfunction is verified. This data opens some study expectation in the diverse picture of systolic and diastolic heart failure.
