The main aim of this states that The prognostic value of asymptomatic perioperative troponin rise in vascular surgery is unclear. We conducted this systematic review and meta-analysis to determine the significance of clinical and subclinical troponin elevation after vascular surgery.
We searched MEDLINE (Ovid), Embase (Ovid), and the Cochrane Library, without language restriction, from inception to May 2019 and included studies that reported associations between elevated postoperative troponin and short-term mortality, major adverse cardiac events (MACEs), or long-term mortality in a vascular surgery cohort. We synthesized study-level data on the maximally adjusted estimates using mixed effects modeling to generate summary odds ratios (ORs) for fixed-interval outcomes and summary hazard ratios for long-term mortality. Between-study heterogeneity was assessed with meta-regression. Methodologic quality and publication bias were formally assessed. We included 24 studies involving 11,657 participants. Postoperative troponin was found to have a strong, positive association with short-term mortality (OR, 4.95; 95% confidence interval.
