Impact of Immediate Versus Staged Complete Revascularization on Short-Term and Long-Term Clinical Outcomes in Patients With Acute Coronary Syndrome and Multivessel Disease: A Systematic Review and Meta-Analysis.

In ACS patients with MVD, we first found that ICR significantly lowered the risk of both short-term and long-term unplanned ischemia-driven revascularization and re-infarction, as well as the long-term composite outcome of CV death or MI compared with SCR. However, there may be an increase in 1-month all-cause death in the ICR group.
