A study of 42,535 patients with non-STEMI and considerable three-vessel or left main coronary disease found no standard threshold for using revascularization treatment. Among the patients, 17.6% were medically managed "even in hospitals with full revascularization capacities" and even though patients with three-vessel disease are known to benefit from revascularization, the researchers wrote. "Since the use of MMS varies widely across hospitals despite a relatively similar hospital-level case mix, these findings suggest that there is no standard threshold for the use of revascularization in [non-]STEMI patients with [three-vessel disease]/[left main disease]," they wrote.
