The predictive value of preoperative silent ischemia for postoperative ischemic cardiac events in vascular and nonvascular surgery patients
Key result
Preoperative silent myocardial ischemia carries a ~38% predictive value for postoperative morbid cardiac events.
- n=146
Why the study?
No controlled data were available regarding the predictive value of preoperative silent ischemia for postoperative cardiac events in nonvascular surgery patients.

Overview
May support preoperative risk stratification in surgical patients; leaves open need for prospective validation before practice change.

Preoperative silent ischemia is a significant predictor of postoperative cardiac events in both vascular and nonvascular surgery patients, highlighting the importance of assessing coronary circulation functional status.
Cite This Study
Fleisher et al. (1991) conducted an observational in Vascular and nonvascular surgery patients with increased risk for cardiac disease (n=146). Preoperative silent myocardial ischemia vs. Absence of preoperative silent ischemia was evaluated on Postoperative morbid cardiac events. Preoperative silent myocardial ischemia had a predictive value of 0.38 for postoperative morbid cardiac events in both vascular and nonvascular surgery patients.
