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).
Why the study?
Does the presence of perioperative ventricular arrhythmias predict adverse cardiac outcomes in high-risk patients undergoing noncardiac surgery?
Population

Does the presence of perioperative ventricular arrhythmias predict adverse cardiac outcomes in high-risk patients undergoing noncardiac surgery?
Odds Ratio: 1.6 (95% CI 0.4–6.2)
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. No 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).
