The Reappraisal of ST Segment Elevation as an Index of Infarct Size in Patients with Acute Anterior Myocardial Infarction : Present Status and Future of Clinical Electrocardiology

The clinical meaning of precordial ST segment mapping for assessment of infarct size was studied in 12 patients with acute anterior myocardial infarction. ΣST_<39> (the sum of ST segment elevations in 39 precordial leads), ΣSTv_<l-6> (the sum of ST segment elevations in the standard chest leads) and ST_<MAX> (the maximum of ST segment elevation in 39 precordial leads) were obtained serially after the onset from precordial electrocardiographic mapping records. The infarct size and the time (Tf) when the evolution of myocardial infarction finished were calculated by the total creatine phosphokinase released (ΣCPK) and serial changes in CPK releasing rate, respectively. ΣSTv_<l-6> at Tf, as closely as ΣST_<39> (r = 0.82, p < 0.01), correlated with ΣCPK (r = 0.79, p < 0.01). Even ST_<MAX> at the time of Tf significantly correlated with ΣCPK (r = 0.60, p < 0.05), although the correlation coefficient was not so well as the former two. These results showed that ΣSTv_<l-6> reflected infarct size as satisfactorily as ΣST_<39> and could be useful for measuring infarct size.
