Left bundle branch block: a hemodynamic and angiographic study.

Coronary angiography, left ventriculography, and hemodynamic data were evaluated in 34 patients with coronary artery disease and left bundle branch block. Left axis deviation (mean frontal axis greater than —30°) was correlated with hemodynamic and angiographic findings. The patients with left bundle branch block and coronary artery disease were compared with 98 subjects with ischemic heart disease without conduction disturbances.

Left axis deviation, which is common in subjects with coronary artery disease and left bundle branch block, had no prognostic hemodynamic significance. Left bundle branch block associated with coronary artery disease did not imply more severe or more extensive coronary atherosclerosis, even though it revealed a higher frequency of lesions of the left main coronary artery and more severe myocardial dysfunction, with asynergy especially involving the anterior areas of the left ventricle.
