Abstract
Objective:To evaluate and automated tracking of mitral annular displacement in diagnosing coronary heart disease(CHD).Method:60 cases of coronary heart disease were selected in our hospital from 2012 to 2013 as the CHD group and 20 cases with normal as the control group.They were all received transthoracic left and right coronary diameter measured.Their apical four-chamber view and two-chamber view images were recorded by PHILIP IE33,the interventricular septum,side wall,front wall and wall motion abnormalities in the change of displacement of mitral valve ring of coronary heart disease group and control group were observed.Parameters included MAD of interventricular septum (MADsep),left ventricular lateral wall(MADlat),MAD of anterior wall(MADant),MAD of inferior wall(MADinf), middle point of mitral annulus(MADmid),and MADmid%was defined as MADmid divided by left ventricular diameter. The results of coronary heart disease group and control group were compared.The correlation between MAD indexes and LVEF and E/A was also explored. Result:According to the results by echocardiography,CHD group was divided into CHDⅠ(with wall motion abnormality)and CHDⅡ(not with wall motion abnormality). MAD indexes were significantly smaller in CHDⅠthan in control group and CHDⅡ,the difference was statistically significant(P<0.001);MAD indexes were no statistical significance in CHDⅡand control group(P>0.05);the ventricular septal MAD side wall,front wall and lower wall were significantly reduced in control group,the difference was statistically significant(P<0.001). Coronary heart disease group and control group by transthoracic left and right coronary diameter there was no significant difference(P>0.05). Coronary heart disease(CHD)Ⅰgroup each movement parameters significantly correlated the left ventricular EF value and E/A value(P<0.001),especially average MADmid%.Conclusion:ATMAD has advantages of easiness,rapid,non-invasion and repeatability. It can be a rapid and stable index for assessment of CHD wall motion abnormality and left ventricular systolic/diastolic function in CHD patients.关键词
