ABSTRACT
Aim: We investigated the relationship between the severity of
reciprocal ST depression and the extent of coronary artery disease
in patients with inferior myocardial infarction.
Method: Ninety-five consecutive patients (52 women 43 men, with a
mean age of 54±5 years) who had acute inferior myocardial infarction
were included in the study. Reciprocal changes in the ST segment were
defined as ST depression of >1 mm in at least two out of four of
the precordial leads V1–V4. All the patients had undergone coronary
angiography within seven days of admission. The extension of coronary
artery disease which was measured by Gensini and Reardon scores,
was compared with the reciprocal changes on ECG recorded at the
time of admission.
Result: There was a significant correlation between reciprocal ST
depression and disease extension (r=0.68 for Gensini score, r= 0.88
for Reardon score, p<0.05 for both).
Conclusion: The presence of ST segment depression in the
precordial leads during the acute inferior myocardial infarction
was associated with greater myocardial necrosis and more frequent
left coronary artery disease.
