Unexplained chest pain in the ED: could it be panic?

Purpose: This study aimed at (1) establishing the prevalence of paniclike anxiety in emergency department (ED) patients with unexplained chest pain (UCP); (2) describing and comparing the sociodemographic, medical, and psychiatric characteristics of UCP patients with and without paniclike anxiety; and (3) measuring the rate of identification of panic in this population. Basic Procedure: A structured interview, the Anxiety Disorders Interview Schedule for the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, was administered to identify paniclike anxiety and evaluate patients' psychiatric status. Anxious and depressive symptoms were evaluated with self-report questionnaires. Medical information was extracted from patients' medical records. Main Findings: The prevalence of paniclike anxiety was 44% (95% CI, 40%-48%) in the sample (n = 771). Psychiatric disorders were more common in panic patients (63.4% vs 20.1%), as were suicidal thoughts (21.3% vs 11.3%). Emergency physician diagnosed only 7.4% of panic cases. Principal Conclusions: Paniclike anxiety is common in ED patients with UCP, and this condition is rarely diagnosed in this population. (C) 2011 Elsevier Inc. All rights reserved.
