[The correlation between left ventricular segmental kinesis and a Selvester QRS analysis in stabilized myocardial infarct].
We have studied the relationship between left ventricular segmental wall motion evaluated by means of biplane left ventricular cineangiography and the myocardial infarct size estimated using Selvester's scoring system based on the QRS of the electrocardiogram. Seventy consecutive patients with old myocardial infarction were recruited. All patients underwent diagnostic retrograde left heart catheterization including left ventriculography and selective coronary arteriography. Nineteen patients were excluded from the study due to intraventricular conduction disturbances and left ventricular hypertrophy. Of the remaining 51 patients, aged 33-76 years (mean 56 years), 31 had inferior or postero-inferior myocardial infarction (Group 1); 7 patients had combined anterior and inferior myocardial infarction (Group 2); 13 patients had anterior or antero-septal myocardial infarction (Group 3). The analysis of left ventricular segmental wall motion was performed according to the Collaborative Studies in Coronary Artery Surgery assigning at hypokinesia, akinesia and dyskinesia 1, 2 and 3 points, respectively. The values of statistical correlations between QRS scoring system and ventricular scoring were: r = 0.85 (Group 1); r = 0.78 (Group 2); r = 0.70 (Group 3). Our data indicate that Selvester's scoring system may provide useful information on functional status and on the extent of left ventricular wall motion abnormalities in patients with previous myocardial infarction.
