Physiology or Angiography-Guided Coronary Artery Bypass Grafting: A Meta-Analysis.

This meta-analysis demonstrated a reduction in all-cause death when a physiology guided CABG strategy was used. Nevertheless, the short follow-up period, small sample size of the included studies and the non-discrimination of the causes of death can largely justify these conclusions. Studies with an extended follow-up period of observation are required to draw more robust and definitive conclusions.
