Abstract
AIM To compare and analyze global and regional ventricular systolic and diastolic functions by radionuclide ventriculography technique in patients with left ventricular myocardial infarction at different locations.METHODS We selected control group(15 cases),inferior myocardial infarction(24 cases),anterior and myocardial infarction(29 cases) for the study and assessed the parameters of global and regional left ventricular systolic and diastolic functions in the three groups.RESULTS ①For left ventricular global systolic function,left ventricular ejection fraction(LVEF) and peak ejection rate(PER) in anterior myocardial infarction group reduced significantly than those in control group and inferior myocardial infarction group respectively(P0.05).②For left ventricular global diastolic function,peak filling rate(PFR) and first third filling fraction(1/3FF) in anterior myocardial infarction group reduced significantly than those in control group and inferior myocardial infarction group respectively(P0.05).③For left ventricular regional systolic function,left ventricular regional ejection fraction(LVREF) in anterior myocardial infarction group reduced significantly in two segments than that in inferior myocardial infarction group(P0.05).④For left ventricular regional diastolic function,left ventricular regional first third filling fraction(LVR1/3FF) in anterior myocardial infarction group reduced significantly in two segments than that in inferior myocardial infarction group(P0.05).CONCLUSION Anterior myocardial infarction has caused more severe damage to global and regional ventricular systoloic and diastolic functions than the damage caused by inferior myocardial infarction.
