Abstract
AIM To assess the parameters of global and regional left ventricular systolic and diastolic function in patients with different-Killip-class anterior myocardial infarction by the technology of radionuclide ventriculography.METHODS A control group of 15 cases(G0),17 cases with Killip-I-class anterior myocardial infarction(G1) and 12 cases with Killip-Ⅱ-and-Ⅲ-class anterior myocardial infarction(G2) were included in the study and the parameters of global and regional left ventricular systolic and diastolic functions were assessed in the three groups.RESULTS ①For left ventricular global systolic function,the two parameters of LVEF and ESC in G1 were significantly different compared with that in G0(P0.05),and the parameters in G2 were significantly different compared with those in G1 and G0 respectively (P0.05).The three parameters of PER 1/3EF and 1/3ER in G2 were significantly different compared with those in G1and G0 respectively(P0.05).②For left ventricular global diastolic function,the four parameters of PFR,1/3FF,1/3FR and EDS in G1 were significantly different compared with those in G0(P0.05) and the parameters in G2 were significantly different compared with those in G1 and G0 respectively(P0.05) ③For left ventricular regional systolic function,the parameters of LVREF in G1 were reduced significantly in four segments compared with those in G0(P0.05) and the parameters of LVREF in G2 were significantly reduced in all the six segments compared with those in G1 and G0 respectively(P0.05).④For left ventricular regional diastolic function,the parameters of LVR1/3FF in G1 were significantly reduced in four segments compared with those in G0(P0.05) and the parameters of LVR1/3FF in G2 were significantly reduced in all the six segments compared with those in G1 and Go respectively(P0.05).CONCLUSION The factors for heart failure after anterior myocardial infarction include left ventricular remodeling,decrease of left ventricular systolic function and left ventricular diastolic dysfunction.
