title: Angiographic correlates of recurrent sustained ventricular tachycardia in chronic ischemic heart disease.
abstract: We report the angiographic studies of 53 consecutive patients with angiographic coronary artery disease (CAD) and recurrent sustained ventricular tachycardia occurring at least 6 weeks remote from an acute myocardial infarction. Triple-vessel disease was present in 25 patients (47%), double-vessel disease in 19 patients (36%), and single-vessel disease in nine patients (17%). All patients with single-vessel disease had left anterior descending coronary artery obstruction. Patients under 50 years old had significantly fewer diseased vessels than those over 50 years old (1.4 vs 2.4 vessels diseased; p less than 0.025). Left ventricular ejection fraction ranged from 0.15 to 0.61 (mean 0.34 +/- 0.11) and was 0.25 or less in 14 patients (26%). All patients had regional wall motion abnormalities. There was akinesia and/or dyskinesia in 49 patients (92%). Akinesia or dyskinesia was inferior in 17 patients (32%), anteroapical in 14 patients (26%), inferoapical in 10 patients (19%), and anteroapicoinferior in 6 patients (11%). Involvement of the septum was noted in 19 patients (36%) and of basal segments in 26 patients (49%). An average of 2.7 (out of seven) segments per patient were dyskinetic or akinetic. Thus multivessel disease, markedly reduced ejection fraction, and severe and extensive regional wall motion abnormalities are generally present. These findings have pathophysiologic as well as clinical and therapeutic implications. The nautral history of these patients as well as the results of therapy should be related to the underlying coronary anatomy and left ventricular function.
