Abstract

Platelets play an integral role in the pathogenesis of acute coronary syndrome (ACS). The purpose of this study was to investigate any correlation between immune thrombocytopenia (ITP) and non-ST segment elevation myocardial infarction (NTSEMI), a common presentation of ACS. Using the large Nationwide Inpatient Sample (NIS) database, we studied any correlation between NSTEMI and ITP utilizing ICD-9 codes. We performed uni- and multivariate analysis adjusting for risk factors from the years 2002–2011. Data was extracted from 106,653 ITP patients and 79,636,090 controls. In multiple years of the study period (2002–2011), NSTEMI incidence was significantly higher in ITP patients when compared with non-ITP patients in the univariate analysis (odds ratio average 1.226). However, no significant association was found after adjusting for additional risk factors in multivariate analysis. Based on our large database study, ITP is not independently associated with NSTEMI incidence after adjusting for comorbidity.
