Data on myocardial infarction (MI) treatment in patients with previous coronary artery
bypass grafting (CABG) is limited. We queried the Nationwide Readmissions Database
to identify hospitalizations of patients with MI from 2016 to 2019. Among hospitalized
patients presenting with MI, 10.3% had previous CABG. Patients with MI who had previous
CABG were less likely to be revascularized than those without previous CABG for both
ST-segment elevation MI (STEMI) (46.4% vs 68.4%) and non-ST-segment elevation MI (NSTEMI)
(30.8% vs 36.7%). CABG was associated with a lower risk of death in NSTEMI patients
(odds ratio [OR] 0.84, 95% confidence interval [CI] 0.82 to 0.86), but a higher risk
in STEMI patients (OR 1.06, 95% CI 1.01 to 1.13). Revascularization was associated
with a lower risk of in-hospital death in patients with previous CABG presenting with
STEMI (OR 0.30, 95% CI 0.26 to 0.35) and NSTEMI (OR 0.21, 95% CI 0.19 to 0.23).
