[Evaluation of left ventricular function and regional kinetics following myocardial infarction. Comparative study of angiocardiography, echography and radionuclide angiography].
Left ventricular function and regional wall motion were studied three weeks after a myocardial infarction in 25 patients who had undergone L.V. monoplane cineangiography. The patients were studied by echocardiography (TM and 2D) and radionuclide angiography. Evaluation of global ejection fraction provides evidence of a close correlation between left ventricular angiography and radionuclide examination (r= 0.79). Measurement of ejection fraction by echocardiography (TM) remains clearly correlated with the same evaluation by angiography (r = 0.68). The correlations are markedly increased in the patients without significant wall motion defects (r = 0.87 for radionuclide angiography and r = 0.82 for echographic measurement). Sensitivity in the detection of L.V. aneurysms is excellent with our method of radionuclide examination (12/13) and can be compared with angiography (12/13). Two-dimensional echocardiography performed on a routine basis is less sensitive than radionuclide angiography in this diagnosis (4/13).
