Cardiovascular Outcomes in Patients With Deferred and Performed Coronary Revascularization Based on Intracoronary Physiology: A Systematic Review and Meta‐Analysis

BACKGROUND: Although large studies and pooled analyses of individual patient data have demonstrated the safety of deferring coronary revascularization based on a nonischemic intracoronary pressure index result, conflicting findings have emerged in specific patient subsets and with varying follow-up. Thus, we conducted an updated comprehensive systematic review and meta-analysis to investigate the cardiovascular outcomes associated with deferred or performed coronary revascularization based on intracoronary physiology. METHODS: Available studies were identified through a systematic search of PubMed, EMBASE, and CENTRAL. Efficacy outcomes investigated were major adverse cardiovascular events, all-cause death, cardiovascular death, noncardiovascular death, myocardial infarction, and unplanned revascularization. RESULTS: =0.11), the associations did not reach statistical significance. CONCLUSIONS: Patients in whom revascularization was deferred based on intracoronary physiology show lower risk of adverse cardiovascular events compared with those who underwent revascularization. These findings suggest that pressure wire assessment has prognostic implications besides the indication for revascularization.
