We evaluated coronary angiography use among patients with coronary stents suffering postoperative myocardial infarction (MI) and the association with mortality.


Patients with prior coronary stenting who underwent inpatient noncardiac surgery in Veterans Affairs hospitals between 2000 and 2012 and experienced postoperative MI were identified. Predictors of 30-day post-MI mortality were evaluated.


Following 12,096 operations, 353 (2.9%) patients had postoperative MI and 58 (16.4%) died. Post-MI coronary angiography was performed in 103 (29.2%) patients. Coronary angiography was not associated with 30-day mortality (odds ratio [OR]: .70, 95% CI: .35-1.42). Instead, 30-day mortality was predicted by revised cardiac risk index ≥3 (OR 1.91, 95% CI: 1.04-3.50) and prior bare metal stent (OR 2.12, 95% CI: 1.04-4.33).


Less than one-third of patients with coronary stents suffering postoperative MI underwent coronary angiography. Significant predictors of mortality were higher revised cardiac risk index and prior bare metal stent. These findings highlight the importance of comorbidities in predicting mortality following postoperative MI.
