ABSTRACT
To investigate the significance of precordial ST-segment depression in acute inferior myocardial infarction, electrocardiographic findings in 51 consecutive patients with acute inferior myocardial infarction were analysed with clinical findings and coronary artery angiography. Thirty patients(Group A) had no or or =1.0mm ST depression in two or more precordial(VI-6) leads were included in this study. Patients in Group B thd greater summed ST-segment elevation in leads II, III, AVF(6.3+/-6.1 vs 2.4+/-2.3mm, p<0.05), higher plasma peak CK levels(1776.8+/-1503.3 vs 5666.6+/-587.7 IU/L, p<0.05), higher plasmal peak CK-MB levels(141.2+/-1553.3 vs 34.1+/-35.7 IU/L, p<0.05), more prevalence of proximal left anterior descending coronary artery disease (46.6% vs 16.6%, p<0.05) than patients in Group A. There was no significant difference between Group A and Group B in the LV ejection fraction, delta area decreasing rate, infarction related asynergy, complications during hospitalization and cardiac events during follow up period. In conclusion, patients with acute inferior myocardial infarction who have associated with precordial ST depression had more extensive myocardial damage probably due to concomitant left anterior descending coronary artery disease.
