| Abstract: | 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 infarc-
tion (group C), with ECGs and UCGs done in alt.
16 cases were angiographically studied. Wall mo-
tion abnormalities were found in 4 cases in group
A, 27 in group B and 9 in group C. 5.18% of the
segments had abnormal waH motion in group A,
31.6% in group B and 63.77To in group C. There was
an inverse relationship between left ventricular wall
motion index (LVWMI) and ejection fraction (EF)
(y=81.3520-1.1601x, 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 bet-
ter prognosis. LV wall motion can help determine
further examinations or treatment in CHD. The LV
function can be assessed indirectly by LVWMI. |
