Fifty-one cases of coronary heart disease (CHD), 44 males and 7 females, aged 39-78 years, were studied. 13 cases were angina (group A), 29, myocardial infarction (group B), and 9, ventricular aneurysm or acute expansion of the zone of infarction (Group C), with ECGs and UCGs done in all. 16 cases were angiographically studied. Wall motion abnormalities were found in 4 cases in group A, 27 in group B and 9 in group C. 5.18% of the segment had abnormal wall motion in group A, 31.6% in group B and 63.77% in group C. There was an inverse relationship between left ventricular wall motion index (LVWMI) and ejection fraction (EF) (y = 81.3520-1.160x, r = -0.78) and the difference in LVWMI among the three groups was significant (p < 0.01). The study suggests that persistent wall motion abnormality in angina pectoris indicates severe coronary artery disease, while normal wall motion in old myocardial infarction is a sign of better prognosis. LV wall motion can help determine further examination or treatment in CHD. The LV function can be assessed indirectly by LVWMI.
