Key result
Significant ST-segment depression during non-cardiac surgery occurred in 38% of patients with known coronary-artery disease, compared to 0% of controls without known disease.
Why the study?
Does lead V5 monitoring detect more intraoperative ST-segment depression than standard lead II monitoring in patients with coronary artery disease undergoing non-cardiac surgery?
Observational (n=40)
Does lead V5 monitoring detect more intraoperative ST-segment depression than standard lead II monitoring in patients with coronary artery disease undergoing non-cardiac surgery?
Absolute Event Rate: 38% vs 0%
Lead V5 monitoring is superior to standard lead II monitoring for detecting intraoperative myocardial ischemia in patients with coronary artery disease.
No takes yet. Share an insight, caveat, or question.
ST depression signals perioperative ischemia risk in CAD patients; leaves open whether routine monitoring improves outcomes.
Roy et al. (1979) conducted an observational in Coronary-artery disease undergoing non-cardiac surgical procedures (n=40). Known coronary-artery disease vs. No known coronary-artery disease was evaluated on Significant ST-segment depression. Significant ST-segment depression during non-cardiac surgery occurred in 38% of patients with known coronary-artery disease, compared to 0% of controls without known disease.
