Associates patent grafts with restored flow reserve and exercise tolerance; leaves open whether bypass surgery improves outcomes in obstructive CAD.
Does aortocoronary bypass surgery improve myocardial blood flow reserve and treadmill exercise tolerance in patients with significant coronary artery obstructions?
Successful aortocoronary bypass grafting with patent grafts restores normal myocardial blood flow reserve and normalizes treadmill exercise tolerance.
