Abstract

Abstract: Objectives: Cocaine use (CU) related chest pain (CP) is a common cause of emergency department (ED) visits in the United States. However, information on disposition and outcomes in these patients is scarce. We conducted a nationwide study to assess disposition from ED, hospitalization rates, in‐hospital outcomes, and health care costs in patients with history of CU who presented to the ED with CP. Methods: We queried the Nationwide Emergency Department Sample database from 2016–2018 for adult patients with CU presenting to the ED with CP. International Classification of Diseases, Tenth Revision codes were used to identify study patients. Results: We identified 149, 372 patients. The majority were male (76%), presented to metropolitan centers (91.3%), and had a high prevalence of cardiovascular risk factors (48.1% with hypertension, 24.4% with coronary artery disease, 18.2% with diabetes) and psychiatric illnesses (21%). Overall, 21.4% of patients were hospitalized, 68.6% were discharged from ED and 6.6% left against medical advice. Patients requiring admission were older (51.8 vs 45.0; P < 0.0001) and had a higher prevalence of coronary artery disease, peripheral arterial disease, hypertension, diabetes, and chronic kidney disease. Of those admitted, 45.7% were diagnosed with myocardial infarction (MI), constituting 9.7% of the total study population. Over 80% of these patients underwent coronary angiography and 38.6% had coronary intervention. Mortality was 1.2%. Conclusion: CU patients who present to ED are predominantly male, are from lower economic strata, and have significant comorbidity burden. One in 5 patients requires hospitalization and has more prevalent cardiovascular risk factors and comorbidities. In‐hospital mortality is low, but incidence of MI and subsequent invasive procedures is high. CU may be considered a cardiac risk factor as it is associated with high rates of in‐hospital MI.
