However, NSTE-ACS patients represent a heterogeneous population, and indication and timing of revascularization depend on many factors, including the baseline risk of the patient.

Early risk stratification is helpful to identify patients at high risk who might benefit the most from a more aggressive therapeutic approach in order to prevent further ischemic events. <Cite>REFNAME28</Cite> | Early risk stratification is helpful to identify patients at high risk who might benefit the most from a more aggressive therapeutic approach in order to prevent further ischemic events. <Cite>REFNAME28</Cite> | ||
