Background:
The goal of this study was to evaluate any association between blunt chest trauma and occurrence of ST-elevation myocardial infarction and non-ST-elevation myocardial infarction.
Methods:
Data from the National Inpatient Sample (NIS) database from 2010-2014, of patients over the age of 40, hospitalized for blunt chest trauma (ICD 959.11), with STEMI or NSTEMI, was used in this study. We performed a chi-squared test to analyze this association. We also performed a multivariant analysis adjusting for race, gender, and age.
Results:
We found that there is not an increased risk of STEMI/NSTEMI following blunt chest trauma, P > 0.05. We also found no correlation between STEMI or NSTEMI and chest trauma after adjusting for race, gender, and age. For STEMI after adjustments in 2010 (P=0.52), 2011 (P=0.19), 2012 (P=0.60), 2013 (P=0.88), and 2014 (P=0.14). For NSTEMI adjustments in 2010 (P=0.03), 2011 (P=0.06), 2012 (P=0.01), 2013 (P=0.21), and 2014 (P=0.03).
Conclusion:
Both ST-elevation myocardial infarction and non-ST-elevation myocardial infarction were not significantly associated with blunt chest trauma.
