Abstract

Background:

The aim of this study was to analyze the indications for using bare metal stents (BMSs) in hospitalizations with ST segment elevation myocardial infarction (STEMI) undergoing percutaneous coronary intervention (PCI).

Methods:

The study cohorts were identified from the National Inpatient Sample database from 2010–2014 using appropriate, International Classification of Diseases, 9th Revision, Clinical Modification, diagnostic and procedural codes.

Results:

A total of 123,487 hospitalizations were identified for this study. Drug eluting stent (DES) use demonstrated lower in-hospital mortality (5.8% vs. 3.3%, P = < 0.01) and other in-hospital outcomes, thus resulting in lower hospitalization stay. Higher age, black race, greater comorbidity burden, inferior wall myocardial infarction, and the use of mechanical circulatory devices were all associated with BMS use.

Conclusion:

DES was the preferred standard of care in the era of 2nd generation DES; however, BMSs were used in hospitalizations with high-risk procedures and multiple risk factors.
