The multicenter, international, randomized trial studied patients who needed a first revascularization because_of severe ischemia with obstructions in two or more major coronary_arteries.
They also had to have clinically severe ischemia but not a prior revascularization.
if they had, for_example, insufficient angina or ischemia, required emergency revascularization, left main stenosis of 50 percent or greater,
and are asymptomatic--experiencing no ischemia, angina,
and had their ischemia return (e_g.,
since they may_not experience symptoms during periods of ischemia.
