Key result
Perioperative ventricular arrhythmias were not significantly associated with nonfatal myocardial infarction or cardiac death in high-risk men undergoing noncardiac surgery (OR 1.6; 95% CI 0.4-6.2).

What is the incidence and prognostic importance of perioperative ventricular arrhythmias in high-risk patients undergoing noncardiac surgery?
Odds Ratio: 1.6 (95% CI 0.4–6.2)
Perioperative ventricular arrhythmias are common in high-risk patients undergoing noncardiac surgery but do not significantly predict nonfatal myocardial infarction or cardiac death, suggesting they may not require aggressive treatment in the absence of other ischemic signs.
Brian O’Kelly (1992) conducted a cohort in Coronary artery disease or high risk of coronary artery disease undergoing noncardiac surgery (n=230). Perioperative ventricular arrhythmias vs. Absence of perioperative ventricular arrhythmias was evaluated on Nonfatal myocardial infarction or cardiac death (OR 1.6, 95% CI 0.4-6.2). Perioperative ventricular arrhythmias were not significantly associated with nonfatal myocardial infarction or cardiac death in high-risk men undergoing noncardiac surgery (OR 1.6; 95% CI 0.4-6.2).
