ABSTRACT
There is no correlation between left ventricular (LV) systolic function and effort capacity of the patients with acute or old myocardial infarction (MI). On the other hand, some recent studies suggest such a relationship for LV diastolic function. Twenty-five patients with old MI were submitted to a maximal symptoms limited exercise testing (ET) and to an echo Doppler examination; functional aerobic impairment (FAI), myocardial aerobic impairment (MAI), maximal exercise capacity (METs NYHA class), isovolumic relaxation time (IVRT), E and A wave velocity, E/A rate being calculated. There is a negative significant correlation between MAI and E velocity (r = -0.68), but not between MAI and A velocity or IVRT. The data sustained the correlation between LV diastolic dysfunction and myocardial ischemia, but not with effort capacity of the patients, the last one being determined mainly by other factors. The LV diastolic function indices were modified in anterior but not in inferior MI, in relation with the amount of myocardial necrosis. It is concluded that, like LV systolic function, LV diastolic function does not correlate with the effort capacity of the patients with MI, but it represents a good predictor of the severity of myocardial ischemia mainly in anterior MI.
