Abstract
Laser doppler flowmetry was used for the intraoperative study of myocardial blood flow before and after revascularization in 116 patients with 2-3 vessel coronary artery disease and class II-IV angina. In patients without myocardial infarction, with microfocal myocardial infarction, or operated early after myocardial infarction revascularization caused no significant increase of myocardial blood flow. In patients with macrofocal infarction surgery was associated with significant increase of myocardial blood flow. Efficacy of revascularization could be assessed by lowering of flow gradients between various regions of the myocardium.
