Landmark Research Studies
completed

The objective of VISION Cardiac Surgery was to determine the relationship between postoperative high-sensitivity Troponin I measurements and the 30-day risk of mortality, the proportion of perioperative myocardial injuries that may go undetected without perioperative troponin monitoring, and the incidence of major vascular complications after surgery.

This cohort study also determined the current incidence of major perioperative vascular events in a representative sample of contemporary adult patients undergoing cardiac surgery.

Primary outcome measures included:

  • All-cause mortality at 30-days after surgery
  • Myocardial injuries that were not identified clinically during the first 5 days after surgery
  • Composite of major vascular complications at 30 days and 1 year post surgery (i.e., a composite of vascular death, nonfatal myocardial infarction, nonfatal cardiac arrest, nonfatal stroke, and mechanical assist device).

VISION Cardiac Surgery will, in turn, facilitate further studies of timely interventions.
