Abstract
This study shows that in patients with subtotal (95% to 99%) coronary artery stenosis, the presence of myocardial ischemia is dictated prima rily by the presence and degree of coronary collateral how, with anter ograde flow participating little, if at all, in the origin of myocardi al ischemia and angina pectoris. Conversely, in patients with severe b ut not subtotal coronary artery stenosis (70% to 94%), both reduced an terograde flow and coronary collateralization contribute to the evolut ion of myocardial ischemia and angina pectoris.
