RESUMO
OBJECTIVE: Despite the favorable data concerning topical agents use in outpatient clinics, they are not commonly in emergency departments (EDs). The present study aimed to compare the effect of 2.5% topical ketoprofen (gel form) to placebo in children presenting with ankle sprain to the ED. STUDY DESIGN: Children between 7 and 18 years old presenting with ankle sprain composed the study population. Study patients were randomized into 2 study arms: 2.5% ketoprofen gel and placebo administered in a 5-cm area locally. Pain improvements at 15 and 30 minutes were measured by visual analog scale. RESULTS: Median pain reductions at 15 minutes for ketoprofen and placebo groups were 27.5 (16-39) and 5 (4-10), respectively. Median changes in pain intensity at 30 minutes for ketoprofen and placebo gel groups were 48 (43-52) and 9 (6-16), respectively. When compared 2 arms for the pain improvement at 15 and 30 minutes, the differences between 2 study drugs were 20 (13-28) and 35 (29-41), respectively. There were 7 (12.7%) rescue drug needs in the placebo group and 1 (1.7%) in the ketoprofen group (difference, 10.9%; 95% confidence interval, -6% to 7%; P = 0.83). There were no adverse effects in either group. CONCLUSIONS: Ketoprofen gel is superior to placebo in ceasing pain in children presenting with ankle sprain to the ED with a high safety profile.

OBJECTIVE: Migraine is a leading headache etiology that frequently presents to the emergency department (ED). In the present study, we aimed to determine the efficacy of dexketoprofen in aborting migraine headaches in the ED. METHODS: This prospective, randomized, double-blind study was conducted in an ED of a tertiary care hospital using allocation concealment. Patients were allocated into two arms to receive the study drug; 50 mg dexketoprofen in 50 ml saline and 50 ml saline as placebo. Change in pain intensity was measured by the visual analog scale at baseline, both at 30 and 45 minutes after the study medication was administered. Rescue medication requirement and pain relapse were also recorded by a telephone follow-up at 48 hours. RESULTS: A total of 224 patients (112 in each group) were included into the final analysis. Mean age of the study participants was 37 ± 11 (SD) and 25% (n = 56) of them were male. The median pain improvement at 45 minutes for patients receiving dexketoprofen was 55 (IQR: 49 to 60) and 30 (IQR: 25 to 35) for those receiving placebo. The mean difference between the two groups at 45 minutes was 21.4 (95% CI: 14.4. to 28.5). Rescue drugs were needed in 22.3% of patients who received dexketoprofen compared to 55.4% in patients who received placebo (dif: 33.1%; 95% CI: 20% to 45%). There were no adverse events reported in either group during the study period. CONCLUSION: Intravenous dexketoprofen is superior to placebo in relieving migraine headaches in the ED. It may be a suitable therapy with minimum side effects in patients presenting with a migraine headache to the ED.

OBJECTIVE: Oligoanalgesia is common in emergency departments (EDs), and pain management is of concern for ED physicians. The aim of this study was to reveal the effect of ketoprofen gel in patients presenting with mechanical low back pain to the ED. METHOD: All the study patients received intravenous dexketoprofen additional to study drugs. After dexketoprofen, 2 g of 2.5% ketoprofen gel or placebo was administered to the site with pain and tenderness. Pain relief at 15 and 30 minutes was measured by visual analog scale scores. Rescue drug need and adverse effects were also recorded. RESULTS: A total of 140 patients were enrolled into the study. The mean age of the study patients was 35±12, and 56% (n=79) of them were male. The mean pain reduction at 30 minutes was 52±18 for ketoprofen gel and 37±17 for placebo, and ketoprofen gel was better than placebo at 30 minutes (mean difference, 16 mm; 95% confidence interval, 10-21). Ten patients (14%) in the placebo group and 2 patients (3%) in the ketoprofen gel group needed rescue drug (P=.35). CONCLUSION: Ketoprofen gel improves pain in patients presenting with mechanical low back pain to ED at 30 minutes in addition to intravenous dexketoprofen when compared to placebo.

OBJECTIVE: The aim of this study is to detect the value of point-of-care ultrasound (POCUS) for diagnosing a nail bed injury and fracture of distal phalanx in patients presenting with distal finger trauma to the emergency department (ED). METHODS: Patients, 18 to 65 years old, presenting with a blunt trauma of distal finger and diagnosed with subungual hematoma were eligible for the study. Subungual hematoma extending over more than 50%, fracture of distal phalanx, and disruption of periungual tissue or nail integrity were accepted as the indications for nail bed inspection. All the study patients underwent POCUS to detect the existence of a distal phalanx fracture or nail bed injury. X-ray was also obtained from all the patients. RESULTS: Nail bed was visualized in 45 patients. Squeezing and crush injury were the most reported trauma mechanism in study patients (66.7%). The sensitivity and specificity of POCUS in detecting nail bed injury were 93.4% (95% CI, 80%-99%) and 100% (95% CI, 74%-100%), respectively. The sensitivity was 100% (95% CI, 79%-100%), and specificity was 98.4% (95% CI, 91%-100%) for distal phalanx fracture. CONCLUSION: Point-of-care ultrasound is a promising tool in detecting the nail bed injury and distal phalanx fractures in patients presented with distal finger trauma. Further studies with bigger sample size are needed to reveal the diagnostic ability of POCUS before using it regularly in the ED.

OBJECTIVE: Point-of-care ultrasonography (POCUS) is an easily available and noninvasive tool without radiation exposure that is also gaining a broad range of use in emergency departments. The aim of this study is to evaluate the value of POCUS in the diagnosis of shoulder dislocation by comparing with plain radiography. METHODS: This prospective observational study with a convenience sampling was conducted in emergency departments of 2 hospitals. Patients older than 15 years with possible shoulder dislocation during the physical examination composed the study population. All the study patients underwent POCUS evaluation to detect a shoulder dislocation or fracture before radiography, and the POCUS procedure was also achieved after the reduction attempt. RESULTS: A total of 103 patients were enrolled in the study. The mean age of study subjects was 33.9±15 years, and 80.6% (n=83) of them were male. The sensitivity and specificity of POCUS in identifying dislocation were 100% (95% confidence interval [CI], 96%-100%) and 100% (95% CI, 48%-100%), respectively. POCUS also confirmed reduction in 93 of 94 patients with a specificity of 100% (95% CI, 96%-100%). POCUS has a sensitivity of 100% (95% CI, 63%-100%) for excluding a shoulder fracture but a specificity of 84.2% (95% CI, 75%-91%). CONCLUSION: Point-of-care ultrasonography is an effective tool to either rule in or rule out shoulder dislocation in the emergency setting. Furthermore, it is a robust sensitive tool for excluding fractures but with false-positive results.

BACKGROUND: High blood pressure is still a challenge for emergency physicians to discern the patients that require further analysis to establish the existence of acute hypertensive target organ damage (TOD). The present study aimed to reveal that adropin levels are useful for detecting TOD in patients presenting with high blood pressure. METHODS: Patients presenting with a blood pressure of more than 180/110 mm Hg were enrolled into the study. After a resting period of 15 minutes, patients' blood pressures were measured thrice at 5-minute intervals while the patients were sitting on a chair, and the average of these measurements was accepted as the baseline value. Blood samples were obtained for either adropin levels or possible TOD during the emergency department admission. RESULTS: A total of 119 patients were included in the study. The mean systolic and diastolic blood pressures of study patients were 204.8±23.2 and 108.3 ± 10.3, respectively, and 42% (n = 50) of the patients had TOD. Although the adropin levels were similar between the patients with or without TOD (TOD group = 195 pg/mL, interquartile range [IQR]: 178-201; no-TOD group = 196 pg/mL, IQR: 176-204 [P = .982]), it is significantly higher in normotensive patients (normotensive group = 289 pg/mL, IQR: 193-403) compared with the hypertensive ones (P < .001). CONCLUSIONS: Despite the significantly higher levels of adropin in normotensive patients compared with hypertensive ones, adropin could not be used as a decision tool for detecting TOD in patients presenting with high blood pressure to the emergency department.

BACKGROUND: There are few data regarding the validity of cardiopulmonary resuscitation (CPR) and basic life support (BLS) videos on YouTube in the medical literature, and those that do are only analyzing adult CPR videos. The present study aimed to determine the reliability and accuracy of pediatric CPR and BLS videos as to whether they are consistent with the 2010 CPR guidelines. MATERIALS AND METHODS: YouTube was scanned in January 2015 using the key words "Pediatric CPR Pediatric BLS" without any filters. The raw data collected in the study included sources that uploaded the videos, the record time, the number of viewers in the study period, and inclusion of human or mannequins. Furthermore, the contents of the videos were evaluated as to whether they are consistent with the 2010 resuscitation guidelines. All videos were seen by two independent researchers (emergency physicians) and scored between 0 and 8. RESULTS: In total, 1,200 videos were evaluated regarding the exclusion criteria, which yielded 232 eligible ones. Most of the videos were found to be uploaded by individuals with unspecified credentials (34.1%). Of the videos, 15.5% have content inconsistent with the 2010 guidelines. The median score of all the videos are not high enough (5 [interquartile range (IQR), 4-7]), and only one-third of the videos have optimal quality with scores of 7 or 8. The downloaded number of videos compatible with guidelines was significantly higher relative to the videos not compatible with the guidelines (15,389 [IQR, 881-31515] versus 477 [IQR, 108-3,797); p = 0.0001). The videos downloaded more than 10,000 times had a higher score than the others (median scores of 7 and 5, respectively; p = 0.0001). CONCLUSIONS: Moderate numbers of YouTube videos purporting to be about pediatric life support have optimal quality, and few of them are perfect. Furthermore, YouTube videos uploaded by news programs with an insufficient quality have the highest download rates.
RESUMO
OBJECTIVE: The therapeutic response of a patient cannot purely be explained by the method of therapy or the efficacy of a drug. Clinician-patient interaction, psychosocial factors, patients' expectations, hopes, beliefs and fears are all related to the healing outcome. Malleability and suggestibility are also important in the placebo or nocebo effect. The purpose of this study was to evaluate whether adding brief verbal suggestions for pain relief could change the magnitude of an analgesic's efficacy. METHODS: This prospective study was performed in the emergency department of a university hospital. Patients who were ordered analgesia with diclofenac sodium for primary headache were divided into three groups. All groups were informed that they would be administered a pain killer by intramuscular injection. The second and third groups were given positive and reduced treatment expectations about the therapeutic efficacy, respectively. Patients were asked to rate their pain on a VAS at 0 and 45 minutes and if they needed any additional analgesic 45 minutes after the injection. RESULTS: A total of 153 patients were included in the study. The paired univariate analyses showed significant differences for all groups between 0- and 45-minute VAS scores. However, there was no difference between the three groups according to the differences in VAS scores between 45 and 0 minutes and according to the administration of an additional drug. CONCLUSION: Simple verbal suggestions did not alter the efficacy of an analgesic agent for headache in an emergency setting. The contributions of suggestibility, desire and expectation in acute primary headache patients should be further investigated.

Migraine is one of the most common causes of headache presentations to emergency departments (EDs). Patients with migraine attack need rapid pain relief rather than diagnostic modalities. Metoclopramide, a dopamine antagonist with a primary use of antiemetic, has been used commonly in ceasing migraine attack. An earlier meta-analysis favors metoclopramide over placebo but includes studies with significant methodological errors and heterogeneity. The present article aimed to review the literature to reveal studies comparing metoclopramide to either placebo or active comparators. A literature search including PubMed, Cochrane Database, and Google Scholar was performed by using the evidence-based process for determining the study quality. Although the studies comparing parenteral metoclopramide to placebo in ceasing migraine headache favor metoclopramide to placebo and lower rates of rescue drug need, however, they lack high methodological quality even to perform a meta-analysis. Meanwhile, the effect of metoclopramide in ceasing migraine headache is also comparable to active comparators. It seems reasonable to use metoclopramide in migraine attacks in EDs according to the current literature. However, further studies with high methodological quality are needed to reveal whether and how much metoclopramide is superior to placebo.

OBJECTIVE: Ketamine is a dissociative anesthetic agent that has an increased frequency of usage in the last years particularly in emergency departments. In the present study, we aimed to determine whether ketamine is related to myocardial injury in children undergoing minor procedures. METHOD: Children younger than 18 years undergoing procedural sedation secondary to minor trauma composed the study population. Patients were administered ketamine with a dose of 1.5 mg/kg via intravenous route. QT interval was measured by Bazett's formula, and QT dispersion was determined by taking the average of 3 different QT intervals. High-sensitive troponin levels were measured before and 3 hours after the ketamine administration. RESULTS: A total of 30 patients were included into the study. Study subjects had a median age of 2 years (interquartile range, 1-4 years). There were 2 patients among the study patients who had troponin elevations 3 hours after the ketamine administrations. High-sensitive troponin levels of these 2 at the time of preketamine, 3, 5, and 24 hours after the ketamine administration were as follows: 5, 29, 15, and 5 ng/L and 3, 44, 41, and 4 ng/L, respectively. There was no difference before and after the ketamine administration for the corrected QT intervals and QT dispersions. CONCLUSION: Ketamine may be related to minor troponin elevations in children undergoing procedural sedation without a permanent cardiac dysfunction.

OBJECTIVE: Critically ill patients have high mortality and admission rates requiring early recognition and a rapid management. In the present study, we evaluated the prognostic parameters in these patients and the value of perfusion index measurement as a novel tool for accomplishing emergency department (ED) triage. METHODS: Seven hundred seventy patients admitted to the critical care area of the ED in a month composed the study population. Perfusion index and vital signs (blood pressure, pulse rate, body temperature, pulse oximeter, and respiration rate) of the study patients were recorded to the study form. The communication data, admitting time, comorbidities, capillary refilling time, and blood gas analysis findings if obtained were recorded. Outcome of patients at the end of the ED period such as discharge, admission to the hospital, and death were also recorded. Outcome of patients at 15th and 30th days was identified by telephone call follow-up or from hospital records. RESULTS: Two hundred seventy-eight patients (36.1%) were admitted to the hospital, 454 patients (59%) were discharged, 3 patients (0.4%) died in the ED, 25 patients (3.2%) were transferred to another hospital, and 10 patients (1.3%) refused treatment and left the ED. Sixty patients (7.8%), 39 (5.1%) of whom had died in 15 days' period, were dead at the end of 30-day follow-up period. Respiratory rate and pulse oximetry were significant parameters in hospital admission. Systolic blood pressure, diastolic blood pressure, pulse rate, respiratory rate, pulse oximetry, lactate levels in blood gas analysis, and ED length of stay were significant variables in 30-day mortality rate. Patients who were admitted to the hospital had higher rates of fever and diabetes. Patients who had died in the 30-day follow-up period had higher rates of diabetes and malignancy. In logistic regression analysis, the predictors of hospital admission were hypotension, fever, and pulse oximetry, whereas the predictors of 30-day mortality were systolic blood pressure, respiratory rate, pulse oximetry, and presence of malignancy. CONCLUSIONS: Perfusion index as a novel triage instrument was found to be an insignificant tool in predicting hospital admission and mortality of critically ill patients in the ED. However, diabetes and malignancy were found to be independent factors in determining the prognosis of these patients in addition to vital signs and should be considered by ED physicians either in triage field or inside the ED.

STUDY OBJECTIVE: The objective of this study was to determine the analgesic efficacy and safety of intravenous, single-dose paracetamol versus dexketoprofen versus morphine in patients presenting with mechanical low back pain (LBP) to the emergency department (ED). METHODS: This randomised double-blind study compared the efficacy of intravenous 1 gm paracetamol, 50 mg dexketoprofen and 0.1 mg/kg morphine in patients with acute mechanical LBP. Visual analogue scale (VAS) was used for pain measurement at baseline, after 15 and after 30 min. RESULTS: A total of 874 patients were eligible for the study, and 137 of them were included in the final analysis: 46 patients from the paracetamol group, 46 patients in the dexketoprofen group and 45 patients in the morphine group. The mean age of study subjects was 31.5 ± 9.5 years, and 60.6% (n=83) of them were men. The median reduction in VAS score at the 30th minute for the paracetamol group was 65 mm (95% CI 58 to 72), 67 mm (95% CI 60 to 73) for the morphine group and 58 mm (95% CI 50 to 64) for the dexketoprophen group. Although morphine was not superior to paracetamol at 30 min (difference: 3.8 ± 4.9 (95% CI -6 to 14), the difference between morphine and dexketoprofen in reducing pain was 11.2 ± 4.7 (95% CI 2 to 21). At least one adverse effect occurred in 8.7% (n=4) of the cases in the paracetamol group, 15.5% (n=7) of the morphine group, and 8.7% (n=4) of the dexketoprophen group (p=0.482). CONCLUSIONS: Intravenous paracetamol, dexketoprofen and morphine are not superior to each other for the treatment of mechanical LBP in ED.

OBJECTIVE: Migraine is a common form of headache that is a major burden for patients who often seek emergency care. The goal of this study was to compare the effectiveness of intravenous non-steroidal anti-inflammatory medication (dexketoprofen) with paracetamol (acetaminophen) in the treatment of an acute migraine attack. MATERIALS AND METHODS: This prospective, randomised, double blind, controlled study was conducted in a tertiary care emergency unit. Study patients were randomised into two groups to receive either 50 mg of dexketoprofen trometamol or 1000 mg of paracetamol intravenously by rapid infusion in 150 mL of normal saline. Pain reduction was measured at baseline, and after 15 and 30 min, using a Visual Analogue Scale (VAS)) as the primary outcome. VAS is a measurement tool ranging from 0 (no pain) to 100 mm (worst pain). RESULTS: 200 patients were included in the final analysis. Mean (SD) age of the study subjects was 30.1 ± 11 years and 81% (n=162) were women. Median reduction in VAS score at 30 min was 56 (IQR 30-78.5) for the paracetamol group and 55 (IQR 34-75) for the dexketoprofen group, with a difference of 1 mm (95% CI -7 to 10) between the two groups. CONCLUSIONS: Intravenous paracetamol and dexketoprofen appear to produce equivalent pain relief for migraine in the emergency department. CLINICALTRIALS.GOV NO: NCT01730326.

OBJECTIVE: To determine the analgesic efficacy and safety of intravenous single-dose paracetamol versus morphine in patients presenting to the emergency department with renal colic. METHODS: A randomised double-blind study was performed to compare the efficacy of intravenous paracetamol (1 g) and 0.1 mg/kg morphine in patients with renal colic. The efficacy of the study drugs was measured by a visual analogue scale and a verbal rating scale at baseline and after 15 and 30 min. The adverse effects and need for rescue medication (1 µg/kg intravenous fentanyl) were also recorded at the end of the study. RESULTS: 133 patients were eligible for enrolment in the study, with 73 patients included in the final analysis (38 in the paracetamol group and 35 in the morphine group). The mean±SD age of the subjects was 30.2±8.6 years and 51 (70%) were men. The mean reduction in scores at 30 min after study drug administration was 63.7 mm (95% CI 57 to 71) for paracetamol and 56.6 mm (95% CI 48 to 65) for morphine. The difference between pain reduction scores for the two groups at 30 min was 7.1 mm (95% CI -18 to 4), demonstrating no statistical or clinical significance. Two adverse events (5.3%) were recorded in the paracetamol group and five (14.3%) in the morphine group (difference 9%, 95% CI -7% to 26%). CONCLUSION: Intravenous paracetamol is effective in treating patients presenting with renal colic to the emergency department. CLINICAL TRIALS REGISTRATION NO: ClinicalTrials.gov ID number NCT01318187.

STUDY OBJECTIVE: We assess whether midazolam reduces recovery agitation after ketamine administration in adult emergency department (ED) patients and also compared the incidence of adverse events (recovery agitation, respiratory, and nausea/vomiting) by the intravenous (IV) versus intramuscular (IM) route. METHODS: This prospective, double-blind, placebo-controlled, 2×2 factorial trial randomized consecutive ED patients aged 18 to 50 years to 4 groups: receiving either 0.03 mg/kg IV midazolam or placebo, and with ketamine administered either 1.5 mg/kg IV or 4 mg/kg IM. Adverse events and sedation characteristics were recorded. RESULTS: Of the 182 subjects, recovery agitation was less common in the midazolam cohorts (8% versus 25%; difference 17%; 95% confidence interval [CI] 6% to 28%; number needed to treat 6). When IV versus IM routes were compared, the incidences of adverse events were similar (recovery agitation 13% versus 17%, difference 4%, 95% CI -8% to 16%; respiratory events 0% versus 0%, difference 0%, 95% CI -2% to 2%; nausea/vomiting 28% versus 34%, difference 6%, 95% CI -8% to 20%). CONCLUSION: Coadministered midazolam significantly reduces the incidence of recovery agitation after ketamine procedural sedation and analgesia in ED adults (number needed to treat 6). Adverse events occur at similar frequency by the IV or IM routes.

OBJECTIVES: The purpose of this study is to examine the relation between end-tidal carbon dioxide (ETCO2) measurement and bicarbonate (HCO3) level reflecting the patient's metabolic status. METHOD: This prospective cross-sectional study has been carried out during a 3-month period in a tertiary care university hospital's emergency department (ED). During the study period, every spontaneously ventilating ED patient requiring arterial blood gas analysis for any medical indication, regardless of presenting symptoms, had a simultaneous ETCO2 measurement using a Medlab Cap 10 side stream capnograph. The demographics and clinical outcomes of the patients were recorded. RESULTS: Of 399 eligible patients, 240 with possible metabolic disturbance were enrolled into the study. There was a statistically significant correlation between the value of ETCO2 and HCO3 levels (r = 0.506). The mean ET(CO)2 level was statistically significantly lower in patients who died (26.5 ± 7.2, 95% confidence interval [CI], 24.2-28.6, vs 30 ± 7.5, 95% CI, 29-31; P = .007) and who had low bicarbonate levels (25.7 ± 6.7, 95% CI, 24.3-27.1, vs 31.6 ± 7.1, 95% CI, 30.4-32.8; P = .000). The value of ET(CO)2 measurement to detect low bicarbonate level was found to be significant. The area under the receiver operating characteristic curve was 0.734, the (+) likelihood ratio for ETCO2 less than or equal to 25 was 2.7, and the (-) likelihood ratio for ETCO2 greater than or equal to 36 was 0.05. CONCLUSION: ETCO2 values correlate moderately with HCO3 levels and thus might predict mortality and metabolic acidosis. Therefore, side stream capnograph can be used as a noninvasive diagnostic tool for ruling out suspected severe metabolic disturbance in the ED.

BACKGROUND: Procalcitonin is a calcitonin precursor that is used as an inflammatory biomarker in the plasma of patients with sepsis. OBJECTIVE: The aim of this study was to determine the diagnostic accuracy of emergency department (ED) point-of-care blood procalcitonin testing in identifying myocardial infarction (MI) in patients with chest pain of presumed ischemic origin. METHODS: Patients over 18 years of age who presented to the ED with MI-typical chest pain of presumed ischemic origin were included in the study. An initial point-of-care blood sample was drawn from each study patient for testing procalcitonin, troponin T, myoglobin, and creatine kinase-MB levels. A second sample was taken 4h after admission for a procalcitonin test. Finally, a 6-h post-admission blood sample was taken to measure troponin T, myoglobin, and creatine kinase-MB levels in each study patient who had an initial negative cardiac marker test. RESULTS: A total of 1008 patients with chest pain were admitted to the ED during the study period, and a total of 141 patients met study criteria and were entered into the study. ED point-of-care blood procalcitonin testing to identify myocardial infarction in patients with chest pain of presumed ischemic origin had a sensitivity of 38.3% (95% confidence interval [CI] 28.8-47.3%) and a specificity of 77.8% (95% CI 70.0-84.4%), a positive likelihood ratio (LR+) of 1.725 and a negative likelihood ratio (LR-) of 0.792. The 4th hour diagnostic values (sensitivity, specificity, LR+ and LR-) of procalcitonin semi-quantitative (PCT-Q) testing were 90% (95% CI 80.9-95.7%), 59.3% (95% CI 52.5-63.5%), 2.2, and 0.16, respectively. CONCLUSION: ED point-of-care testing for procalcitonin had poor diagnostic accuracy for predicting myocardial infarction.

Palpitation is a common chief complaint among emergency department patients, and is often associated with a tachydysrhythmia. Tachydysrhythmia is classified as supraventricular tachycardia or ventricular tachycardia. Reentry in a normal or accessory pathway is one of the most frequently seen mechanisms explaining the tachydysrhythmia. In the present case, we report an unusual cause of atrioventricular paroxysmal supraventricular tachycardia due to pseudoephedrine intake.

OBJECTIVE: The aim of this study was to determine the prevalence of anxiety and depressive disorders in patients presenting with chest pain to the Emergency Department (ED) and determine if there is a relationship between these and cardiac vs. non-cardiac chest pain. METHODS: This prospective cross-sectional study was performed in an urban tertiary care hospital between March and October 2005. Consecutive patients presenting with chest pain were enrolled in the study. The prevalence of anxiety and depressive disorders in patients with chest pain were determined by using the Hospital Anxiety and Depression Scale. RESULTS: A total of 324 patients presented to the ED with chest pain during the study period. The mean age of the patients studied was 50.5 +/- 14 years; 67% were men and 33% were women. Of the 324 study patients, 194 (59.9%) patients were diagnosed with non-cardiac chest pain, 16 (4.9%) with stable angina, 84 (25.9%) with unstable angina, and 30 (9.3%) with acute myocardial infarction. No statistically significant differences were determined between patients with cardiac and non-cardiac chest pain both for anxiety (40% vs. 38.1%, respectively; p = 0.737) and depressive disorders (52.3% vs. 52.1%, respectively; p = 0.965). CONCLUSION: Anxiety and depressive disorders are common among patients presenting with chest pain to the ED. However, the prevalence of anxiety and depressive disorders is similar between patients with chest pain of cardiac and non-cardiac origin. Chest pain should not be attributed to an anxiety or depressive disorder before organic etiologies are excluded.
