Effects of previous coronary artery bypass graft surgery on in-hospital mortality in ST-segment elevation myocardial infarction: National dataset analysis.

ABSTRACT:

Background

Association of history of coronary artery bypass graft surgery (CABG) with clinical outcomes in patients presenting with ST-segment elevation myocardial infarction (STEMI) is unclear from current data.

Methods

Using Nationwide Inpatient Sample (NIS) data from 2003 to 2014, adult patients hospitalized with principal diagnosis of STEMI were extracted. The cohort was divided into patients with a history of CABG and those without a history of CABG. The primary outcome measure was in-hospital mortality (IHM).

Results

2,710,375 STEMI patients were included in final analysis of which 110,066 had history of CABG. Patients with history of CABG had higher unadjusted (12.2% vs. 8.8%, P < 0.001) and adjusted (odds ratio [OR]1.16; 95% confidence interval [CI] 1.1
