Abstract:

In this paper 80 casea of myocardial infarction receiving non-in -vasive techniques to assess the left ventricular function by Echocardiography (EF, Ejection Fraction) and STI (Systolic Time Interval, PEF/LVET) were reported. The results showed:(1) Both the Echocardiographic and STI findings were all consistant with the clinical features. So it can be used as an useful objective index for the assessment of left ventricular function. (2) It may predict the potential reduction of the left ventricular function. (3) Echocardiography is much more sensitive than other techniques and is also frequently in accordance with the findings of catheterization in the same patient.
